Joseph M. Hogan -- Director, President and Chief Executive Officer

Thanks, Shirley. Good afternoon and thanks for joining us. On our call today, I'll provide some highlights from the fourth quarter and full year, then briefly discuss the performance of our two operating segments Clear Aligners and Systems and Services. John will provide more detail on our financial results and share additional color on business trends. Following that, I'll come back and summarize a few key points and open the call to questions.

Our fourth quarter was a strong finish to the year with record revenues and volumes from both Invisalign aligners and iTero scanners, as well as increased gross margins, operating margins, EPS and cash flow. Our fourth quarter performance is driven by strong year-over-year growth across customer channels and regions and continued momentum sequentially. During the quarter, we achieved a major milestone in EMEA with the shipment to our 2 millionth Invisalign patient that will be amplified with the EMEAwide campaign that will launch next month. This milestone from reflects strong acceleration in Invisalign adoption and growth.

For Q4, total revenues were $834.5 million, up 13.7% sequentially and up 28.4% year-over-year. Q4 '20 Clear Aligner revenues of $700.7 million million were up 12.9% sequentially and increased 28.9% year-over-year. In Q4, we shipped a record 568,000 Invisalign cases, an increase of 14.5% sequentially and 37.3% year-over-year.

Q4 reflects increased Invisalign adoption from both adults and teenagers, which were up 36.7% and 38.7% year-over-year respectively. Our Teen and Mom-focused consumer campaign generated 77% year-over-year increase in unique visitors to our website and 76% increase in leads generation.

In addition, Invisalign social media influencers like Charli D' Amelio, Marsai Martin, Christina Milian, Tisha Campbell-Martin, Rachel Zoe, Tiffany Ma, and Tahj Mowry continued to deliver exciting new content and increased engagement for the Invisalign brand with consumers and among their millions of followers.

Our digital platform continues to gain traction as doctors uses of iTero scanners increase. Our Consumer and Patient app was rolled out to more than 50 markets, resulting in more than a 2.5 times increase in apps download and monthly active users in 2020 versus a year ago. Our patient feature usage continues to increase, for example, Invisalign Virtual appointment was used 68,000 times. Our insurance verification feature was used 26,000 times and more than 30,000 patients enrolled in Invisalign Virtual Care in 2020.

Our new consumer website was rolled out to more than 40 markets around the world and is driving increased effectiveness in lead generation. We also launched an improved new doctor recruitment website in the U.S. and Canada to support our digital conversion journey. This will be expanded to other markets in the next few months.

From a product perspective, growth was strong across Invisalign portfolio, especially for non-comprehensive cases including Invisalign Go and Invisalign Moderate. There are also more doctors engaging with us through the Align Digital and Practice Transformation or ADAPT program, as more practices are moving toward digital practice optimization. As you'll recall, ADAPT was piloted over two years ago and is being commercialized as a stand-alone service providing the relevant workforce, clinical and marketing support to enable doctors to digitally transform their practices.

In Q4, we shipped a record 77,000 Invisalign doctors worldwide of which a record 7,300 were first time customers. We also trained over 6,400 new docs in Q4, including over 3,900 international doctors.

Q4 '20 System and Services revenues of $133.8 million were up 18% sequentially driven by momentum in the Americas and EMEA, and up 26% year-over-year, reflecting strong growth in EMEA and Asia Pacific. Our results reflect continued strong uptake of the iTero Element 5D, the only intraoral scanner with caries detection which is scaling rapidly across each region and represented approximately a third of iTero volumes in Q4.

Innovation remains a cornerstone of our business. Today, we announced the availability of the iTero Element Plus Series, which expands our portfolio of iTero Element Scanners in Imaging Systems to include new solutions that serve a broader range of the dental marketplace. The new iTero Element Plus Series of scanners in Imaging Systems builds on the success of the award winning iTero Element family and offers all of the existing orthodontic and restorative digital capabilities doctors have come to rely on, plus faster processing time and advanced visualization capabilities for seamless scanning experience in a new sleek ergonomically designed package.

We announced the launch of our next-gen ClinCheck Pro 6.0 proprietary treatment planning software with in-face visualization and our Invisalign G8 improved predictability in our last earnings call we announced. Their availability is being expanded across all regions. Further, we launched several enhancements to our treatment planning, including improved Final teeth position and Auto segmentation. We also added several new features to our Virtual Care tool.

For the full year 2020, total net revenues were a record $2.5 billion, up 2.7% year-over-year. Clear Aligner revenues of $2.1 billion were up 3.7% reflecting a record $1.6 million Invisalign shipments and growth of 7.9%. During the year, 30.3% of total Invisalign cases or nearly 500,000 teens or younger started Invisalign treatment. This is up 11.5% from 2019. System and Services revenues were down slightly compared to 2019.

2020 was a year unlike any other that we've experienced. The COVID-19 pandemic and its impact have been life-changing, marked by loss and separation, recovery and renewal, record highs and lows, and significant milestones and accomplishments. Even in a time of huge disruption, we all had to adapt, evaluate priorities and develop new ways of doing things both personally and professionally. Through it all, Align's priority has been the health and well-being of our employees and their families and our doctor, customers and their staff. And that remains a constant.

Despite the swift onset of the pandemic and the uncertainty through 2020, we didn't hold our plans or change our strategy for continued growth. We completed the acquisition of exocad, accelerated our investments in marketing to create Invisalign brand awareness and drive consumer demand for our doctors' offices. Accelerated new technology to market with virtual tools that enable our doctors to stay connected with their patients, provided PPE to those in need and supported doctors and their teams with online education and digital forums that went beyond products to help them navigate the uncertainties of the pandemic. As a result of our continued strategic focus and investments, we exited the year stronger than we started and 2021 is off to a great start.

Now let's turn to the specifics around our fourth quarter starting with the Americas. With the Americas region, Q4 Invisalign case volume was up 12.7% sequentially and up 34.1% year-over-year, reflecting increased utilization of Invisalign treatment for both orthodontic and GP channels. Our continued investments in digital marketing and sales programs and focus on market segmentation are helping drive strong growth of Invisalign Clear Aligners and iTero products. During the quarter, we continued offering sales initiatives to our doctor partners to help drive adoption of Invisalign and iTero products.

The Bracket Buy Back-Switch program, which we launched in North America in Q2 '20 continues to drive conversion from wires and brackets to Invisalign clear aligners. During Q4, this program resulting -- has resulted in about 10,000 new cases similar to Q3. We believe this is also causing a halo effect with patients switching from wires and brackets to Invisalign clear aligners with increased awareness of the benefits of Invisalign treatment and how it is less disruptive to their lives with the outcome of a beautiful smile through an Invisalign trained doctor.

The Teen Awesomeness Centers programs direct patients to Invisalign doctors who are experts at treating teens and are seen as the go-to docs for treatment. We continue to see growth with Invisalign First for treatment in younger kids driving increased comprehensive treatments within North America Ortho channel.

Latin American volume was also up year-over-year, led by strong growth in Brazil and Mexico. We believe the market for orthodontic treatment is huge in Latin America as we continue to grow our presence across the region.

We saw increased utilization in the GP channel with Invisalign Go and the continued adoption of Moderate. The GP Accelerator program designed exclusively for general practitioner dentist provides an all-encompassing support plan based on practice needs that is centered around maximizing iTero integration, clinical support needs, and implementing new marketing strategies. We also see increased utilization with GP dentists that have enrolled in the iPro program as well as with doctors that have installed the iTero scanner. DSO utilization also increased and continues to be a strong growth driver led by Heartland and Smile Docs. For the full year, Americas Invisalign volume was up 3.6%

For our International business, Q4 Invisalign case volume was up sequentially 6.7% [Phonetic], led by a strong growth in EMEA as doctors returned from summer holiday season, offset somewhat by seasonally slower period in China. On a year-over-year basis, International shipments were up 41.1%, reflecting increases throughout both EMEA and APAC. For the full year, International Invisalign volume was up 13.3%.

For EMEA, Q4 volumes were up sequentially 47.9% and 48.3% on a year-over-year basis across all markets, with strong performance across both Ortho and GP channels. Within the GP channel specifically, we saw acceleration in both utilization and shipments with Invisalign Go. We also saw acceleration in both core and expansion markets, with growth in our core markets, led by Iberia, UK and France, along with continued growth in our expansion markets, led by Central and Eastern Europe and the Benelux.

We introduced the Ortho Recovery 360 Program in EMEA last quarter to support our orthodontists as they started reopening their businesses. As of Q4, 3,200 orthodontists have enrolled in the program. During the quarter, we launched the Recovery II Program with a refreshed website featuring all digital tools, growth programs and education events for EMEA doctors to support their relief efforts during COVID-19.

We also held our Digital Innovation Forum at the beginning of December where approximately 900 doctors, both Ortho and GP, attended the two-day forum event with keynotes on the digitization of dental practices. We also continued our Digital Excellence Series of webinars launched by the iTero team.

Throughout the quarter, the following digital innovations were also launched across EMEA, Invisalign G8, ClinCheck Pro 6.0 and Invisalign Go Plus, to help drive Invisalign clear aligner utilization. To support our GP doctors, we launched our GP Recovery 360 program last quarter, with over 2,700 GPs enrolled so far. We continued to offer online and on-demand education events, which reached over 15,000 GPs cumulatively. For the full year, EMEA Invisalign volume was up 12.6%.

For APAC, Q4 volumes were down sequentially 14.7%. Notwithstanding typical Q4 seasonality in China, following a strong Q3, we had strong growth in Japan and ANZ and Southeast Asia. On a year-over-year basis, APAC was up 30% compared to the prior year, reflecting continued strong growth across the region. We were pleased to see growth in the Adult segment with non-comprehensive cases with the Invisalign Moderate product in the GP channel. In the Teen segment, we also saw an increase in utilization among Invisalign doctors and we saw continued acceleration from Japan and ANZ. For the full year, APAC Invisalign volume was up 14.3.%.

Last year, we launched a new and improved digital learning environment for our doctors offering a comprehensive learning platform with role-specific content for orthos, GPs and their teams. The improved functionality enables more online learning opportunities with spotlight features for what's trending now, recommended learning path based on doctors' experiences, and expanded categories including digital treatment planning, comprehensive dentistry, and team education.

For the year, over 127,000 doctors have accessed recorded lectures, completed self-paced learning modules, and watched how-to videos, with new certified doctors viewing more than 1.4 million pages of content. Among the ortho channel, over 47,000 unique users have engaged with the digital learning site with an additional 80,000 unique users from the GP channel.

As we've mentioned, we are seeing good adoption of the ADAPT program, which is an expert and independent fee-based business consulting service offered by Align to optimize clinics' operational workflow and processes to enhance patient experience and customer and staff satisfaction, which will in turn translate into higher growth and greater efficiencies for orthodontic practices. As a result, the ADAPT service participating practices in Q4 improved profitability significantly after implementation.

Our consumer marketing is focused on capitalizing on the massive market opportunity to transform 500 million smiles, educating consumers about the Invisalign system and driving that demand to our Invisalign doctor offices. In Q4, we saw strong digital engagement globally with more than 77% increase in unique visitors, 108% increase in doc locator searches and 76% increase in leads created, driven by our global adult and mom-focused campaigns and teen-focused influencer content.

Our US Mom/Teen multi-touch multimillion dollar campaign with influencer-led YouTube videos, a mom-focused TV spot, a custom Twitch activation, and mega teen sensation Charli D'Amelio continued to perform very well and garnered 2.7 billion impressions in Q4. The statistics I shared previously speak to the successful reach of this marketing campaign is having to not only drive demand with consumers, but also in educating them on the benefits of Invisalign treatment through a doctor's office.

In Q4, we also launched media tests in the EMEA region in the UK, Germany and France and in the APAC region in Australia and Japan. These have worked very well and resulted in a more than six-times increase in leads in EMEA and a 3-times increase in leads in APAC. Several key metrics that show increased activity and engagement with the Invisalign brand are included in our Q4 quarterly presentation slides available on our website.

Align is always looking for new opportunities to reach consumers and be relevant to potential patients wherever they work, live, and play, which is why we announced that the Invisalign brand is the Official Clear Aligner Sponsor of the National Football League, the NFL, and 11 NFL teams, including the Tampa Bay Buccaneers and the Kansas City Chiefs. The NFL league partnership, designed to expand our reach with consumers, generated over 150 million impressions in 2020, helping to drive awareness of Invisalign clear aligner treatment at a national level, while the team agreements are designed to help us engage within key markets and connect consumers with doctors in those markets.

For our Systems and Services business, Q4 revenues were up 18% sequentially due to higher shipments and services revenues. We continued to see momentum with the iTero Element 5D Imaging System, gaining traction in all regions with significant Element Flex sales in EMEA. On a year-over-year basis, Systems and Services revenues were up 26% due to higher shipments and services. For the year, our Systems and Services total revenues were down 2.8% year-over-year. Cumulatively, over 31.4 million orthodontic scans and 6.7 million restorative scans have been performed with iTero scanners.

For Q4, total Invisalign cases submitted with a digital scanner in the Americas increased to 84% from 79.5% in Q4 last year. International scans increased to 73.7%, up from 64.7% in the same quarter last year.

We're pleased to see that within the Americas 94.8% of cases submitted by North American orthodontists were submitted digitally. We're also proud to share that iTero Element intraoral scanners are the winners of the 2020 Dentaltown Townie Choice Award for Digital Impressioning category.

Also, during the quarter, the National Association of Dental Laboratories judging panel selected the iTero Element 5D as the winner of the 2020 Journal of Dental Technology WOW! Award. The award represents the recognition of our commitment to enhancing patient engagement and communications that support efficient laboratory production.

For exocad, during the quarter we launched two of the largest software releases in history, DentalCAD and exoplan. DentalCAD3.0 Galway includes over 90 new features and over 80 enhanced functionalities with significant improvements to reduce design time, such as Instant Anatomic Morphing. exoplan 3.0 Galway includes over 40 new features and over 60 enhanced functionalities that support planning of edentulous cases, including the design of surgical guides. During the quarter, exocad also added two new large implant manufacturers as OEMs for exoplan in Brazil.

With that, I'll now turn it over to John.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Thanks, Joe. Now for our Q4 financial results. Total revenues for the fourth quarter were $834.5 million, up 13.7% from the prior quarter and up 28.4% from the corresponding quarter a year ago. For Clear Aligners, Q4 revenues of $700.7 million were up 12.9% sequentially and up 28.9% year-over-year reflecting Invisalign volume growth in all regions, partially offset by lower ASPs.

Clear Aligner revenues growth was favorably impacted by foreign exchange of approximately $5 million or approximately 0.8 points sequentially and on a year-over-year basis by approximately $10.3 million or approximately 1.9 points.

Q4 Invisalign ASPs were down sequentially $15 primarily due to increased revenue deferrals related to a higher mix of new cases versus additional aligners, partially offset by favorable foreign exchange, and lower promotional discounts. As we mentioned last quarter, we did not implement a price increase in 2020 given our continued commitment to helping our customers in their recovery efforts during the pandemic. On a year-over-year basis, Q4 Invisalign ASPs decreased approximately $75 primarily due to our decision not to raise prices last summer, increased revenue deferrals for new cases versus additional aligners, and higher promotional discounts, partially offset by favorable foreign exchange. As a result, clear aligner deferred revenue on the balance sheet increased $83 million sequentially and $195 million year-over-year and will be recognized as the additional aligners are shipped. Total Q4 Clear Aligner shipments of 568,000 cases were up 14.5% sequentially and up 37.3% year-over-year.

Our System and Services revenues for the fourth quarter was $133.8 million, up 18% sequentially due to an increase in scanner sales and increased services revenues from our larger installed base and higher ASPs. Year-over-year System and Services revenue was up 26% due to higher scanner sales, services revenue, and the inclusion of exocad's CAD/CAM services, partially offset by lower scanner ASPs.

Imaging Systems and CAD/CAM Services deferred revenue was up 30% sequentially and up 69% year-over-year primarily due to the increase in scanner sales and the deferral of service revenues, which will be recognized ratably over the service period.

Moving on to gross margin. Fourth quarter overall gross margin was 73.2%, up 0.4 points sequentially and up 0.5 points year-over-year. On a non-GAAP basis, excluding stock-based compensation expense and amortization of intangibles related to exocad, overall gross margin was 73.6% for the fourth quarter, up 0.3 points sequentially and up 0.7 points year-over-year.

Clear Aligner gross margin for the fourth quarter was 74.9%, up 0.1 point sequentially due to lower additional aligner volume, partially offset by higher warranty, other manufacturing costs and lower ASPs. Clear Aligner gross margin was up 0.7 points year-over-year primarily due to favorable product mix from increased iTero scanner absorption as a result of increased manufacturing volumes partially offset by lower ASPs, higher warranty costs and other manufacturing costs.

Systems and Services gross margin for the fourth quarter was 64.2%, up 2.2 points sequentially primarily due to higher ASPs and increased manufacturing efficiencies from higher productions volumes. Systems and Services gross margin was down 0.7 points year-over-year due to lower ASPs, higher freight and other manufacturing costs partially offset by higher services revenue.

Q4 operating expenses were $397.3 million, up sequentially 11.3% and up 23.8% year-over-year. The sequential increase in operating expenses is due to increased marketing and media spend and spending commensurate with business growth. Year-over-year, operating expenses increased by $76.5 million, reflecting our continued investment in sales and marketing, R&D activities, and manufacturing operations.

On a non-GAAP basis, operating expenses were $372.3 million, up sequentially 12.1% and up 23.4% year-over-year due to the reasons as described earlier. Our fourth quarter operating income of $213.2 million resulted in an operating margin of 25.5%, up 1.4 points sequentially and up 2.3 points year-over-year. The sequential and year-over-year increases in operating income and the operating margin are primarily attributed to higher gross margin and operating leverage. On a non-GAAP basis, which excludes stock-based compensation, amortization of intangibles related to exocad, and acquisition-related costs, operating margin for the fourth quarter was 28.9%, up 0.9 points sequentially, and up 2.5 points year-over-year.

Interest and other income and expense, net for the fourth quarter, was a benefit of $1.4 million, primarily driven by favorable foreign exchange.

With regards to the fourth quarter tax provision, our GAAP tax rate was 25.9% which includes tax benefits of approximately $11 million related to adjustments in prior years' unrecognized tax positions. The fourth quarter tax rate on a non-GAAP basis was 14.5% compared to 16.6% in prior quarter and 20.9% in the same quarter a year ago. The fourth quarter non-GAAP tax rate was lower than the third quarter's rate primarily due to the reason previously stated.

Fourth quarter net income per diluted share was $2.00, up $0.24 sequentially and up $0.47 compared to the prior year. On a non-GAAP basis, net income per diluted share was $2.61 for the fourth quarter, up $0.37 sequentially and up $0.85 year-over-year.

Moving on to the balance sheet. As of December 31, 2020, cash and cash equivalents were $960.8 million, an increase of approximately $345.3 million from the prior quarter, which is primarily due to higher cash flow from operations. Of our $960.8 million of cash and cash equivalents, $548.3 million was held in the U.S. and $412.5 million was held by our International entities.

Q4 accounts receivable balance was $657.7 million, up approximately 5% sequentially. Our overall days sales outstanding was 71 days, down approximately 6 days sequentially and down approximately 5 days as compared to Q4 last year due to strong cash collections.

Cash flow from operations for the fourth quarter was $381.4 million. Capital expenditures for the fourth quarter were $53.2 million, primarily related to our continued investment in increasing aligner capacity and facilities. Free cash flow, defined as cash flow from operations less capital expenditures, amounted to $328.3 million. Under our May 2018 Repurchase Program, we have $100 million still available for repurchase of our common stock.

Before we move to the outlook, I would like to make a few comments on the full year 2020 results. In 2020, we shipped a record 1.6 million Invisalign cases, up 7.9% year-over-year. This reflects 13.3% volume growth from our International doctors and 3.6% volume growth from our Americas doctors.

System and Services volumes were down 12% compared to 2019, reflecting the impact of COVID-19 pandemic on equipment sales.

Total revenue was a record $2.5 billion, up 2.7% year-over-year, with Clear Aligner revenues a record $2.1 billion, up 3.7% year-over-year.

2020 Systems and Services revenues were $370.5 million, including exocad revenues from April 1, 2020 forward compared to $381 million in 2019. Full year 2020 operating income of $387.2 million, down 28.6% versus 2019 and operating margin at 15.7% versus 22.5% in 2019.

2019 operating income included a litigation benefit of $51 million and Invisalign Store closures of $23 million for a net benefit on operating margin of 1.1%. With regards to a full year tax provision, our GAAP tax rate was negative 368.6%, which includes a one-time tax benefit of approximately $1.5 billion, net of current year amortization, associated with the recognition of a deferred tax asset related to an intra-entity sale of certain intellectual property rights resulting from our corporate structure reorganization completed in the first quarter of 2020. Excluding the tax benefit related to our corporate structure reorganization and the related tax effects of stock-based compensation and other non-GAAP adjustments, the full year tax rate on a non-GAAP basis was 17.6% compared to 22% for 2019.

2020 diluted EPS was $22.41. On a non-GAAP basis, 2020 diluted EPS was $5.25. Free cash flow was $507.3 million for 2020, down $90.3 million versus 2019.

Now let me turn to our outlook. Overall, we are very pleased with our Q4 performance and the strong momentum in our business, which has continued through January for both Clear Aligners and Systems and Services. As we discussed at our Investor day in November, we are committed to making significant investments to drive growth and we are seeing good return on these investments across all regions and customer channels. These strong returns give us confidence to continue investing in sales, marketing, innovation and manufacturing capacity to accelerate adoption in a huge, underpenetrated market. These investments coupled with typically higher seasonal operating expenses as a percentage of revenue are expected to result in a sequentially lower operating margin percent in Q1 as we have historically seen.

While the global environment surrounding the pandemic remains uncertain, we will continue to focus on what we can control and we are confident in our ability to continue to execute. Our responsibility is to continue driving innovation and delivering on the needs of our customer doctors and their patients. Over the past 24 years, Align has invested billions in technology, innovation, consumer marketing and demand creation to connect millions of consumers with our doctor customers. We will continue to invest in this business to drive demand and to drive adoption of the Align Digital Platform, including manufacturing and operational expansion. We will always be responsible. Just like we've done in the past, we make investments to drive growth and maximize ROI. We remain committed to our long-term target model of 20% to 30% revenue growth for Clear Aligners and Systems and Services, and operating margin of 25% to 30%.

With that, I'll turn it back over to Joe for final comments. Joe?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Thanks, John. The choices we made in 2020, to protect employees, support customers, and press forward on our strategy for growth, were possible because of the strength of our balance sheet and the confidence we have in our business model. Our actions reflect our conviction in the enormous opportunity we have to transform smiles and change lives. With 15 million orthodontic cases starts annually and more than 500 million consumers who can benefit from a better smile, the market for digital orthodontics and restorative dentistry is massive and has been unleashed by the need for digital.

In a macro sense, COVID-19 has accentuated the benefits and pervasiveness of the digital economy. From an Align standpoint, practices across every region are embracing digital treatment in new ways and more purposefully than ever before. Invisalign providers are using our virtual tools to minimize in-office appointments and deliver doctor-directed, personalized treatment that meets the needs of the moment and that will reshape the future of treatment. Digital acceleration is not just around Invisalign treatment. It includes digital workflows around iTero scanners and general dentistry. Doctors tell us that the iTero scanner is central to their practice and their practice workflows, and it is key to driving digital treatment. We've always known this, iTero and now exocad are core components of the Align Digital Platform, our integrated suite of unique, proprietary technologies and services delivered as a seamless, end-to-end solution for patients and consumers, orthodontists and GP dentists, and lab partners. And particularly, we now have all the building blocks to create digital workflows, leveraging the combined power of Invisalign treatment, iTero scanners, and exocad software to become more relevant to the GP market, which is critical to accessing the 500 million consumer opportunity. Align is a growth business with huge opportunities, but the environment remains uncertain due to COVID-19. Our plan is still to counter uncertainty by staying focused on our long-term strategy, living our values, supporting our employees and customers, and keeping in mind the demand drivers we've identified over the past year, the redirection of disposable income for many consumers, channel focus that allows us to reach and support a wider range of customers within each channel. And most importantly, the digital mindset that's taking hold with more and more of our customers and that we are supporting through innovative products and programs that can help support their digital transformation.

We are not ignoring the reality of COVID-19 and how long it may be part of our lives, but we're also not going to stop driving the business forward for the good of customers and their patients, our employees, and our stakeholders. In closing, I want to leave you with a few thoughts as we begin the new year. While there is considerable amount of turmoil in the world, our focus is on what we can control as a company. We have strong momentum. We'll stay focused on our strategic priorities, international expansion, patient demand and conversion, orthodontist utilization, and GP dentist treatment.

In summary, we are very pleased with the fourth quarter and full year results of 2020, during a remarkable year with events beyond our control as a result of COVID-19. It is during times such as this when having a solid strategy combined with focused execution can lead to outcomes that support growth, not only for Align's business but also practice growth for Align's customers which also leads to more and more Invisalign smiles.

With that, turn it over to the operator and we'll take calls.

Questions and Answers:

Operator

[Operator Instructions] Thank you. Our first question comes from Ravi Misra with Berenberg Capital Markets. Please proceed with your question.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hi, Ravi.

Ravi Misra -- Berenberg Capital Markets, LLC -- Analyst

Hi. Thanks for the question. Hi. How are you?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Good.

Ravi Misra -- Berenberg Capital Markets, LLC -- Analyst

Happy New Year. So I just wanted to maybe start on -- I'll let the others maybe talk about the quarterly trends, but one of the things that kind of stood out to me was you're driving extremely strong volume growth amid what's kind of a stable to slightly declining pricing environment. Just curious, first, when do you think you'll be able to go back to the kind of prior model where you're able to take pricing? Is that still in the cards? And then secondly, I think the teen market is an area that we've kind of always been looking at as the next leg of growth, the kind of huge market that's out there. And you're talking about some of the conversion and the lead generations. Can you help us understand kind of the conversion rates around the leads that you generate in terms of timing and how long this takes to get the ROI that is put into the advertisements that you're putting out there?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, Ravi, first of all, I guess, your first question is on average selling prices. We try to communicate this as strongly as we can is to keep your eyes on gross margin, because we have huge mix, whether it's international mix or it's product mix, you see a lot of progress in iGo and products like Moderate and Invisalign First in those products. The carry actually lower average selling prices, but higher margins, and so you can often mix up on those things. So I'd say as we keep emphasizing is don't be overly concerned about ASPs or focused on ASPs. Like John said, we didn't increase ASPs this year because we're interested in supporting our customers and making sure that this is difficult -- a really difficult transition for many practices right now and instituting a price increase just wouldn't have been responsible in that sense. But at the same time, we drove incredible productivity across the business and we're able to show those kind of gross margins. So I hope you and the rest of the analysts community out there can actually see that. We've been talking about this for a few years, but actually taking place.

On the teen side and the conversions from an advertising standpoint, I mean, we come out just from a lot of different ways and a lot of different areas. And we -- if we are going to start teen season, you really have to start in February in the United States and you have to really work through a lot of different aspects of social media. You advertise differently for moms and you do teens and different things like that. So I can't give you a correlation coefficient in the sense of here we invest and how much we get back, but we understand as well as a business, we've been doing it for years. We understand the timing of it. And more and more we become more specific on the social advertising pieces and how to implement that properly. And John, do you have anything you want to add?

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

No. As you said, I mean, it's -- there's others that are in the equation. You have to reach the teen, as Joe described, and we talked about social influencers and so on. You have to reach the parents and we try that. And then also have the right formula with the doctors. So getting those three to think about going into treatment is really the key.

Ravi Misra -- Berenberg Capital Markets, LLC -- Analyst

Okay. Then maybe one last one if I can ask one more, just on the reopening and vaccination progress and kind of volumes. How are you guys kind of thinking about the consumer spending environment as the options that the patient is going to have start increasing. I mean is that going to require more investment here in the near term or do you think kind of where we're at a baseline where you've kind of gotten the ramp where things are starting to really click here with the advertising that you're doing as is? Thank you.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Yeah, Ravi, it's a good question. I mean, look, we're always looking to maximize our return on investment. We talk about that to grow in this vastly underpenetrated market. In some countries like in the U.S., it's just a matter of refining how we spend. We talked about the influencers, talked about NFL and other things. And in other countries, we've really started spending some of that consumer advertising and we see a great response and we see a strong return. And those are areas that, as we see that response, we see it turn into volume, those are areas that will continue. So we're always looking at return on investment and we'll find ways to be able to grow our volume that way.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, Jon.

Jonathan D. Block -- Stifel, Nicolaus & Company -- Analyst

Hey, Joe. Good afternoon. Joe, you mentioned 2021 is off to a great start. From 2015 to 2019, so I'm sort of isolating pre-COVID management guidance for 1Q cases, the guidance for 1Q cases were up pretty consistently, just low single-digits off of what you did in the fourth quarter. And I guess where I'm going with this is at a high level, what's the expectation for case growth sequentially? And I'm just trying to level set as the back part of 2020 likely benefited from some pent-up demand. So just how we should think about the trend line, if you would, into the early part of 2021?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, Jon, I'll let John have the specifics. I would just tell you that January was a really strong orders quarter, so that momentum really continues.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

And look, Jon, I think as we've said it, we're controlling what we can control, making investments that help drive this business. We look at -- as Joe said, we felt really good about how we exited Q4. We saw that in January as well, and we don't want to guide. We basically haven't because there is things that are outside of our control. And we'll leave that as it is. What we're trying to give you is kind of the latest information without projecting forward.

Jonathan D. Block -- Stifel, Nicolaus & Company -- Analyst

Okay, fair enough. And I'll ask a quick two-part for the second one. EMEA was just gangbusters, I mean, it was up 48% of a 32% comp, shout out to Markus, but anything to call out there? I mean, the number was huge. And then the second part is teen up almost 40%, Joe. What do you think the underlying ortho market was growing? Where I'm going with this is just your conviction of sort of maybe a type of inflection point, if you would, with teen's share of share. Thanks, guys.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, Jon, I appreciate you bringing up EMEA, I mean, that was just an amazing performance when you see that. I've been doing business in Europe since I was 30 years and you see growth like that by countries, it's amazing. And I think that, to me, that was really a story on the fourth quarter too was the breadth of that growth. It wasn't just North America. It wasn't just Asia. It was deep across segments, across GPs, across orthos. So Jon, I'm not ready to talk about an inflection point. All I can say is when you think about, we had 77,000 doctors that ordered that I talked about in my script. And then 7,200 to 7,300 more doctors, that's 10% more doctors, that's a record for us too. So we see Invisalign, this digital treatment really catching on in a big way and it's meaningful. Look, we're gearing up for it. We're obviously advertising to drive that demand and will stay focused on just executing, Jon, right now.

Jonathan D. Block -- Stifel, Nicolaus & Company -- Analyst

Thank you. Our next question comes from Steve Beuchaw with Wolfe Research. Please proceed with your question.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hi, Steve.

Steve Beuchaw -- Wolfe Research -- Analyst

Hi. Thanks for the time here, guys. I wanted to try to understand a little bit better the relationship between some of the things that you flagged, John, in your prepared remarks as it relates to deferrals and ASP. I certainly agree with the view that gross margins are really the critical metric, but I'm sure we're going to get a lot of questions about ASP tonight and over the next couple of days. So I wonder if you could help us understand a little bit more deeply, one, why we'd be seeing more deferred revenue here both on aligners and scanners? And what's the relationship to ASP and do we see that reverse?

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Yeah, Steve, the basic way to think about this as we look at our revenue, we've got revenue on a new case that we ship out. And there is a certain amount that you recognize on that shipment based on our rev rec. And then there is a certain amount for future aligners or future modifications that are needed. That will be deferred revenue. And then you also get into your revenue so that those deferrals that you've made for maybe previous quarters or even previous year that as they -- that doctor needs to use that additional lines, you're going to get revenue for that.

When you have a mix like we have, where there is much more, there is this demand for future volume for new cases, you get a mix where we just have a lot more as a percentage of new cases and that's what impacts ASPs. When we look at that from a margin standpoint, it's margin accretive. We're getting as new cases. Many of the cases that we get back from a deferred revenue standpoint where there's refinements we just don't make as much margin on that. You get the deferred revenue, but you don't get as much of the margin. So there is those dynamics that we have. We saw just when you have a significant volume increase like we saw in our third and fourth quarter.

Steve Beuchaw -- Wolfe Research -- Analyst

Okay. Thank you, John. And then I wanted to follow-up about the GP channel. GP has been just gangbusters here lately. I wonder if I could try to understand that a little bit more deeply. One is do you think it continues to grow at the sort of clip relative to the ortho channel? Maybe two, do you think exocad has been a driver of incremental growth in that channel at this point? And then lastly, should we think about the shift to DSOs being a variable one way or another. And I apologize for my kids screaming in the background.

Joseph M. Hogan -- Director, President and Chief Executive Officer

That's the life we live now, Steve. We understand. It happens on and off like every call. From a GP channel standpoint, I mean, three years ago when we first started segmenting in Europe and now we are doing in the States and we do it all over the world. And then we introduced products like iGo that were specific to it. And just a salesforce that can communicate with GPs because it's a different conversation than with orthos. Yes, I can't tell you where it's going, but when we talk about that 500 million patients like I did in my script, that's where they are, and that's where you touch them. I mean, it's a different. It's not a big teen market. It's a lot of adults. But it has to have a workflow that's specific to a GP. And that's why we drive their products, that's why iTero is so important from a front-end standpoint.

Your question on exocad is we think that's going to be a big GP driver for us. It is a big legitimate piece for us, but I don't think it's adding to volume right now. We're just rolling out these new products. We're just starting to integrate that kind of software code into iTero and into our programs and that's certainly will drive increased penetration in the future.

Steve Beuchaw -- Wolfe Research -- Analyst

Got it. Thank you so much for all the perspective here.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Operator

Thank you. Our next question comes from Jeff Johnson with Robert W. Baird & Co. Please proceed with your question.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hi, Jeff.

Jeff Johnson -- Robert W. Baird & Co. -- Analyst

Thank you. Good evening, guys. Hey, Joe. I wanted to start with -- I know it's tough and maybe there is not even a way to do it, but any way to think about especially over the last two quarters, how much of this patient volume has been backlog versus the zoom effect versus true kind of accelerating penetration of clear aligners versus brackets and wires. Just is there any way to bucket or any metrics you're looking at that tells you this is truly kind of that secular uptick we've all been waiting for versus backlog and some of the zoom effect?

Joseph M. Hogan -- Director, President and Chief Executive Officer

I think as we get further and further from the second quarter obviously the backlog question becomes less and less as part of the noise of the structure, right. I feel a lot of analysts, Jeff, they wonder, hey, we had a great third quarter obviously and it was, well, how much of that was really the second quarter that's rolled into the third. We really don't know what that was. We don't. And our doctors don't know it either as we talk to them. The fourth obviously had less of that.

And we really felt good about our orders in January too. So I think we're really moving away from that question here soon. The number of docs like I just quoted with over 7,000 new docs ordering from us, 77,000 in total shows you the breadth of what's going on. And what's really struck me in this entire thing too, Jeff, is really this is not just United States, this is all over the world. It's Latin America, it's APAC. It's tremendous growth in Japan and ANZ and traditional markets, in China, in Europe. So there is breadth to this and then the segments we talked about, both GPs and orthos. So look, there have been backlog in the third quarter. There has to be some backlog in the fourth quarter or whatever. But we don't think that's the overriding story here.

Jeff Johnson -- Robert W. Baird & Co. -- Analyst

Yeah, that's fair. And then one other kind of maybe more a conceptual question. Just as I think about -- I think about it through your Advantages program, but are you seeing doctors that are the high volume guys, the Platinum guys moving up to Diamond and Double Diamond? Is it the lower Bronze or Gold guys moving up to Platinum? Does it matter to you which it is? But more importantly conceptually, is it getting those low volume guys to really go all in here or the high volume guys to convert completely to Invisalign? And I'm sure you're going to tell me it's a mix of both of that, but just kind of what you're seeing would be helpful there on your own customer base.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Yeah. You helped me answer that question, Jeff, it is a mix. But it is really broad. I mean, we see in the Bronze accounts and Golds and all the way to Diamond and Diamond Plus. And we see growth in all those segments. And I think it's kind of logical, right. The people that know how to do digital are going to expand on it, because digital really allows them to function in this COVID environment in a way that allows them fewer customer touches and they can actually carry on their practices in a normal way. Other doctors actually see the advantages of that. They have patients asking for them. And they start to move toward a digital kind of a platform. And overall, again, it's a breadth discussion. It's not just one area, it's not just one country, it's not one segment of the Advantage program. We just weren't seeing adoption across the board. And John, anything to add on that?

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

I'd echo this, the breadth. I mean, you have new doctors, like Joe said, 7,000 new doctors that come in with and want to do cases that come into our ecosystem and start cases. You see doctors who have done just a few cases really start to accelerate and then at the top of the pyramid, you have people that are doing a lot of cases and they do even more cases. So that's part of when we talk about the breadth of this growth and what makes it excited. And it's like Joe said, not just a U.S. phenomena, it's pretty much everywhere.

Joseph M. Hogan -- Director, President and Chief Executive Officer

And Jeff, I think the last thing you said is do you care which I thought was kind of interesting is like we really don't care. We just want to serve the doctors who want to work with us. We see this market -- we talk about how large this market is and and how under-penetrated it is. And we just want to see wherever that growth is, that's great. It's on the low end, that's terrific. It's on the high end, that's terrific. We set this company up to be able to service either side to work well with them.

Thank you. Our next question comes from Elizabeth Anderson with Evercore. Please proceed with your question.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hi, Elizabeth.

Elizabeth Anderson -- Evercore ISI -- Analyst

Hi, guys. Thanks so much for the question. Hey, Joe. I always thought -- obviously the -- one of the many nice parts of the quarter was the scanner and CAD/CAM revenue. Can you talk a little bit about what you sort of see as market growth there? Like where are you taking share? Is it in the GP, more on the ortho channel? Is it orthodontists adding their third scanner? Is it people finally saying, yes, I'll go digital? Obviously, the total number of cases submitted digitally was very high. Any other color you could provide there would be really helpful.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Elizabeth, you could work for us, OK. You kind of described exactly how that demand is, it's coming from all these different places. And a lot of it when you say where you're taking share, a lot of is just analog share. There is so much in dentistry is still just completely analog. They're still doing impression and different pieces. And so it's the growth has been tremendous in that sense.

Your question about orthodontists that start to move up into a significant part of their practice being Invisalign, you'll see -- you see a scanner at every chair. And they use these things are constantly. It's part of what they do. What we see on the GP segment is the communication tool ends up being the scanner in the front of the scanner. Because you know in the past, they'd hold up a mirror and say, can you see that, that second molar back there and you'd say, yeah, but you really couldn't, right. Now, you throw it on a screen. It's live, you can see exactly what's going on. It becomes an incredible patient-communication tool in a sense of where is your dentist and what needs to be done and helps to convince patients of what the doctor wants to do and the validity of that kind of treatment. So this is where dentistry is going. And when you look at iTero, it is arguably the highest performing scanner in the world, the speed of it, the exactness of it, color rendering, and also with NIRI technology to be able to see caries or cavities is a real benefit, even to orthodontists who want to make sure that before you start the treatment that dentition is in good enough shape to able to except that kind of movement. So that's just -- this is the time for digitization inside of dentistry and iTero plays a big role in that and it front-ends our digital platform.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Especially in a COVID environment, given the fact that you don't want to have as much time for impressions and so on and you want to be able to have something that's fast and really be part of that digital workflow, this iTero lends itself well.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Yeah.

Elizabeth Anderson -- Evercore ISI -- Analyst

Okay, that's super helpful. And Joe, sort of like to just follow up more a housekeeping question. One, obviously you announced the new products today and I imagine that that's something you'll be talking about in sort of the virtual Chicago Midwinter and what you would have discussed a lot of it IDS. Is there anything we should keep in mind in terms of the ramp of sort of new products or impacts from IDS moving to the back half of the year? And then on the other side, obviously we saw your announcement about the move to Arizona. Sounds exciting. I just didn't know if that had any impact in terms of something we should model in on taxes or anything else just to touch on that as well.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Yeah, I think I can answer the tax piece of it. No, really not a tax impact. It really came down to when we look at the campus that we have in San Jose and the expansion that we have from a technology center, we become space constraint. And so we want to keep that technology center, that innovation center in San Jose and expand that out and add more to help with that innovation. And then moving to here in Tempe for kind of that head office just made sense to us.

Elizabeth Anderson -- Evercore ISI -- Analyst

Okay, thanks.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Yeah, it is upon the new product pieces. Keep in mind we talked about we spend $500 million a year on advertising and also new product development, you'll see a lot of new products. We don't pace ourselves on those introductions based on IDS. And that's why we obviously announced the new iTero scanner. We talked about the new 6.0 software that we have. A lot of changes to FiPos, it's our final positioning aspect to dentition. We had the Plus product from iGo, the in-face visualization. This is a digital business that requires constant iterations in products. And obviously Midwinter and those things are great places to highlight it. But our innovation, we looked at it agile, not waterfall anymore. In the sense, waterfall used to be invent during the year, release one period of the year. More and more, you'll see us just monthly just rolling out new products as we adapt to a more kind of an agile philosophy of development than a waterfall type of -- if that's what you're asking, Elizabeth.

Elizabeth Anderson -- Evercore ISI -- Analyst

Makes total sense. Thank you so much.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Thank you. Our next question comes from Richard Newitter with SVB Leerink. Please proceed with your question.

Richard Newitter -- Leerink Partners -- Analyst

Hi, thank you for taking the questions. Just maybe to start off the Switch program, which has fairly been extremely successful for you. I'm curious to know how much more runway there is associated program, and maybe if you could just comment on kind of how you're at least thinking about that from your internal modeling?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Yeah, look, I think it has a huge amount of breadth to it. I mean, it's not just U.S. We started this in Japan actually years ago and introduced in the United States. And you think about -- it's just a great winner, detaching those wires and brackets from people's teeth using Invisalign, understanding, like we said, in our script, is how much more simple it is and better for people and comfortable for people to go with our product line. So we think it's -- we have a lot of room to grow and we're going to keep supporting it.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

Yeah. And Rich, it's John. I mean, we are always looking at those types of promotions for an ROI. And in these cases, many cases looking at it from an incremental standpoint, nothing could be more incremental than it was glued onto someone's teeth and now they come off and they go to Invisalign. So we like those dynamics there. It sends a great message. And those people who had wires and brackets on their teeth can talk about their experience with Invisalign. So there is a lot of positives to it, as Joe said, it started in Japan. And we've seen great success in the U.S. and we look to other places as well.

Richard Newitter -- Leerink Partners -- Analyst

Got it. Helpful. And Joe, you said a few times how encouraging the trends have been in January. I'm just curious, understanding it's only one month, but how well is the growth, if the trend that you're seeing now were to whole kind of for a good portion of the year, where in your long-term kind of long-range plan of 20% to 30% do you think you'd be falling toward the mid to upper end? I'm just trying to get a sense for kind of what do you think in there?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Nice try, Richard. Look, we're very committed to our long-term growth model 20% to 30%. That's really all I can say right now. Rich, we're in a really uncertain environment. We're happy about January. It is why we're not giving guidance. It's -- we're all living with volatility right now and we'll just continue to execute and keep our heads down, but we're committed to that 20% to 30% growth model that we've been talking about for several years.

Thank you. Our next question comes from John Kreger with William Blair. Please proceed with your question.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, John.

John C. Kreger -- William Blair & Company -- Analyst

Hey, Joe. Just sticking with that answer, you were obviously above that in terms of volumes in the fourth quarter. How do you feel about your ability to deliver on that if the order flow were sustained? In terms of fabrication and fulfillment, how are those metrics holding up at this point?

Joseph M. Hogan -- Director, President and Chief Executive Officer

Our supply chains, we try to keep ahead in that sense. So, I feel we have adequate plans and capacity right now to be able to handle the surge in demand.

John C. Kreger -- William Blair & Company -- Analyst

Great. Okay. And then, John, I think you've talked about in the past a reasonable assumption is kind of a flattish ASP, and realized there's a lot of puts and takes. But is that still a reasonable kind of planning thing for us? Or are you guys thinking less on the pricing front, and, therefore, maybe more of a downward trend over the coming year?

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

It's tough because it really becomes kind of the end result, because if you have more primary cases as I spoke compared to secondaries, you can get some of these impacts in ASPs. I think, in general, there is not a significant change that we would expect in some of the mix or some of that some of that pricing. So that being said, you wouldn't expect too much fluctuations in ASPs. But like I said, it depends on that demand that comes forward from our doctors.

John C. Kreger -- William Blair & Company -- Analyst

Got it, OK. And then one more, Joe, sorry, in a typical year, we'd assume kind of teens would be big in Q3 and adults would be bigger in Q4. Is that same sort of seasonal pattern likely do you think in '21 given what we know now, or would you expect kind of teen order flow to be more kind of spread evenly throughout the year.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Hey, John, we don't know. But I'd say it became muted this year. Obviously, we saw as much stronger fourth quarter United States in teens than we saw -- that you normally see from a seasonal standpoint, it got continued. So I think all of us are expecting summer and fall months as COVID to start to retreat a little bit, that might take us back to the patterns that we had before. But I don't think it's going to be binary. I really don't, I think this could have changed the pattern. We're just going to have to -- we're going to have to just ride the curve here and see how it goes. But we'll continue to advertise through this to execute on a place that we talked about in our scripts and we've really feel confident we can continue to drive significant teen demand.

John C. Kreger -- William Blair & Company -- Analyst

Okay. Our next question comes from Jason Bednar with Piper Sandler. Please proceed with your question. Hey, good afternoon, everyone. Thanks for taking my questions here. Congrats on another really strong quarter. I appreciate all the details you discussed. Maybe building off some of the real-time commentary you shared at the end of your prepared remarks there, Joe, just curious if you can expand on what you're seeing in January for maybe a utilization perspective, maybe in the context of where we were October through December, any notable call-outs in January from a good geographic perspective or teens or adults?

Joseph M. Hogan -- Director, President and Chief Executive Officer

I think the call-out, Jason, really is just the breadth of it really. There wasn't any geography in particular that dominated or it was just in segment to GP and ortho continued to be strong. So when you exit a year and you're at our new year, you're obviously glued to that month to see, especially in a business like this, what the momentum is and we just see a continuation of the strong momentum that we had in the fourth quarter. That's -- John, anything to add on that.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

I think the breadth of it is my note on this that we have across geographies between GP and orthos. And what we described is a lot of doctors that are higher-up in the tier, they're continuing to do a lot of volume, and then a lot of new doctors that come in that come in with cases in hand. And we can get them to start the Invisalign system into our digital ecosystem. So, that continued from Q4 into Q1.

Jason Bednar -- Piper Sandler -- Analyst

Okay. That's helpful, guys. And then just focusing on China here just for a quick moment. There wasn't a great deal of discussion probably less in this call than maybe any other call in recent memory on China in particular. But impression, the seasonality that happens here in the fourth quarter, but maybe just wondering if you can expand on what you're seeing with your business and the Clear Aligner market in China specifically and maybe compare that against some of your other APAC markets.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Yeah, we felt good about our growth in China 26% for the quarter overall. China, we see shutdowns periodically, issues in Shanghai or different places and Chinese are pretty draconian, I'd use the move is when they COVID, they move pretty quickly. The public hospitals have been throttled to certain extent unlike the procedures. But we feel good about the quarter and we feel, honestly, our investments in China, we really feel good about those. The manufacturing piece helps legitimizes us our IT systems from a data protection standpoint have to be geared toward China. We're in good shape with that. We're assembling iTero there now. We feel great about our training centers, great about our treatment planning capabilities. So overall, we remain bullish on China and we think that China will start to, with the rest of the world, will start to recover in the second half of next year too and we expect to be a big part of that.

Jason Bednar -- Piper Sandler -- Analyst

Okay. Our last question comes from Nathan Rich with Goldman Sachs. Please proceed with your question.

Nathan Rich -- Goldman Sachs Group, Inc -- Analyst

Hi, Nathan.

Jason Bednar -- Piper Sandler -- Analyst

Hey, Joe. Good afternoon. Thanks for squeezing me in. Obviously, results over the past couple of quarters have been really strong. I guess, when we look out to 2021, it's tough to know what happens with COVID, but hopefully we'll start to get back to normal life later this year or 2022. I think as we look at where consensus is modeled I think on a high-teens revenue growth. It seems like you still feel comfortable with the 20% to 30% target. So do you feel like we should be expecting that type of growth in line with the long-term range off of this new higher level of volumes that you're starting to see in the back half of this year.

Joseph M. Hogan -- Director, President and Chief Executive Officer

Nathan, that's -- we try to emphasize as much as we can, we feel very confident about those 20% to 30% ranges of growth. And continue to target 25, 30% operating profit to in order to do that. So you'll see us in investor rates that John talked about we're putting in place to drive that demand. So we make -- we remain committed to that model growth.

John F. Morici -- Chief Financial Officer and Senior Vice President, Global Finance

And it starts with the vastly under-penetrated market and the investment opportunities we talk about. We tried to give you a kind of the breadth of all the different levers that we have to pull to be able to drive that return. And we continue to make that. It changes over time in terms of how we invest and where and so on, but that, that belief is still there. And when we make those forward investments, we're invested into that under-penetrated market that we think we can grow 22% in and do it at a 25%-plus op margin rate.
