Thanks, Shirley. Good afternoon, and thanks for joining us. On our call today, I'll provide some highlights from the quarter and then briefly discuss the performance of our two operating segments, clear aligners and scanners. John will provide more detail on our financial results and discuss our outlook for the third quarter. Following that, I'll come back and summarize a few key points and open up the call to questions. Our second quarter results were better than expected across all key financial metrics, including revenue volume, margins, and EPS. Q2 revenues increased 32.3% year-over-year, driven by strong Invisalign case shipments across all channels and especially in the teen segment. Solid execution of our strategy and key investments continue to deliver strong growth across the board with record Invisalign volume in almost every geography.
Q2 also had an all-time high of nearly 5,000 newly trained doctors in a quarter for the first time ever. Our iTero scanner business also performed well this quarter, with revenues up 36.7% year-over-year. For Q2, North American Invisalign case volume was up 10.3% sequentially and 27.6% year-over-year, reflecting strong year-over-year growth from both orthodontist and GP dentist channels. Continued uptake with teens drove Invisalign growth in North America and contributed to another record quarter for ortho volumes, up 34.5% year-over-year, and in utilization up to 13.6 cases per doctor. Q2 volume for North America GP dentists increased 18.9% year-over-year, primarily reflecting continued expansion of our GP customer base and utilization growth, which increased to a record 3.3 cases per doctor.
Q2 was the first quarter we offered Invisalign Lite in North America. We saw solid uptake, especially among GP dentists. Invisalign Lite includes up to 14 stages of aligners and is intended to treat simple to moderate cases. Q2 Invisalign volume for international doctors was up 13.6% sequentially and 37.4% year-over-year, driven primarily by new customers in both EMEA and APAC regions. In EMEA, Q2 volumes were up 33.2% year-over-year. All five of our core European markets showed record growth rates led by Spain and the U.K. Expansion markets also had record volume with over 50% year-over-year growth led by Central and Eastern Europe and the Benelux. In Asia Pacific, Q2 volumes were up 44.4% year-over-year, led by China, where we trained over 1,000 doctors for the first time, followed by growth from Southeast Asia, Japan, and ANZ.
Turning to the teen market, over 55,000 teenagers started treatment with Invisalign clear aligners in Q2, up 12.6% sequentially and 37.6% year-over-year, reflecting continued acceleration above adult case volume growth. North America ortho teen cases increased 11.6% sequentially and 42.1% year-over-year, compared to adult cases of 9.8% and 30.5%, the third consecutive quarter teen growth rate that has been above adults. International case shipments to teen patients increased both 13.7% sequentially and 40.5% year-over-year as well. In Q2, we expanded commercialization of Invisalign treatment with Mandibular Advancement to select countries in EMEA and APAC. MAF, as we call it, is the first clear aligner solution for Class II correction that advances the mandible while moving teeth at the same time.
While it's still very early in the adoption cycle to date, we're pleased with the initial uptake and expect to see continued ramp-up over the course of the year. Invisalign treatment with Mandibular Advancement is not available in the U.S. yet, where it's pending FDA approval. The Invisalign brand and our consumer marketing campaign programs continue to be key factors in raising awareness and creating demand for Invisalign treatment. In Q2, we continued to benefit from our investments in new programs, as well as optimizing online spending and media mix for existing programs. In the U.S., we launched our new teen-focused marketing campaign in May that aims to educate teens and their parents, moms especially, about the benefits of teeth straightening with Invisalign clear aligners. It also works to ensure that teens know Invisalign treatment is the best option for their lifestyle.
The new program contributed to significant growth in consumer demand during the quarter that helped drive Invisalign teen volume. Our teen campaign expands to the Invisalign Made to Move campaign that we introduced in March, and we continue to see positive impact from the overarching campaign on consumer interest as well. Specifically, in Q2, we saw a 23% year-over-year increase in unique visitors to our website and achieved significant growth year-over-year in doctor locator searches. We also saw a continued uptick in adult male patients as compared to females as a result of our changing consumer targeting approach. In EMEA, early results show the Invisalign Made to Move campaign is resulting in higher engagement with consumers across digital display, PPC, and social channels. During the quarter, we piloted new social media formats that delivered exceptional results. Pinterest, Facebook Canvas, and Instagram all outperforming benchmarks.
Social media remains a key driver, delivering 200% more users. Although we also saw a significant increase in the number of smile assessment completions, +22%, and total leads, +30%, and we'll continue to roll out the Made to Move campaign across the remaining countries in EMEA in Q3. In the Asia Pacific region, our Q2 customer marketing campaigns focused primarily on Australia and New Zealand, where we saw momentum from our summer campaign featuring Invisalign ambassador John Burgess, a well-known TV host and personality in Australia. The campaign shares John's personal journey of how Invisalign treatment helped transform his smile and his career, along with a call to action for consumers focused on their New Year's resolution to improve their lives by getting the smile they've always wanted.
We also continue driving Invisalign website doctor locator visits by reaching out to potential patients who engaged with our ads and banners in Q1. In India, where we're just getting started, we participated in Beach Fashion Week, where the Invisalign brand was a beautiful smile partner. In Q2, our scanner revenues increased 36.7% year-over-year and 26.9% sequentially. In May, we announced the new iTero Element 1.5 software upgrade, which includes two key features, time lapse and one-minute scans. Time lapse compares a patient's prior 3D scans to their most current scan and gives doctors an enhanced visualization assessment and communications tool that can help them provide additional treatment recommendations. One-minute scans enable practitioners to complete a full-arch scan in less than a minute with the same accuracy and reliability practitioners have come to expect from iTero scanners.
The use of our iTero scanners for Invisalign case submissions in place of PVS impressions continues to expand. It remains a positive catalyst for Invisalign utilization. In Q2, total Invisalign cases submitted with a digital scanner in North America increased to a record 59%, up from 47% in Q2 of last year. In the doctor-directed at-home channel, Q2 was our second full quarter supplying clear aligners to SmileDirectClub or SDC. Q2 shipments to this new channel were strong and nearly tripled sequentially off a small base. As their exclusive third-party supplier, we produce roughly one-third of SmileDirectClub's clear aligner volume, and they manufacture the remaining amount. In Q2, SDC continued to invest significantly in consumer marketing, including TV advertising, print, online media, including social media, which we believe has a positive effect on both SDC and Invisalign demand.
They also opened several new SmileShops in the U.S., which are continuing to ramp. Overall, we're excited about the long-term potential for the at-home doctor-directed market, remain pleased with our investment and supply agreement. Today, we also announced that we have purchased an additional 2% of SmileDirectClub for $12.8 million, which brings our total ownership to 19%. We've extended SDC's line of credit from $15 million to $30 million. Finally, before I turn the call over to John, I want to provide a brief update on our operational expansion plans. In June, we opened a new treatment planning facility in Chengdu, China, which services and supports our customers within China. It also serves as a clinical education and training center for all of our customers across Asia Pacific. We have been steadily migrating Chinese Invisalign cases to Chengdu and are continuing to train new technicians and improve lead times.
We will also open a treatment planning facility to support our EMEA customers in Cologne, Germany, in Q3. With that, I'll turn it over to John.
Thanks, Joe. Now for our Q2 financial results. Total company revenue for the second quarter was a record $356.5 million, up 14.9% from the prior quarter and up 32.3% from the corresponding quarter a year ago. Clear aligner revenue of $321 million was up 13.7% sequentially, driven primarily by better-than-expected Invisalign shipments and higher Invisalign ASPs. Year-over-year clear aligner revenue growth of 31.9% reflected strong Invisalign shipment growth across all customer channels and geographies and increased prices. This was partially offset by product mix shift to non-comprehensive products, primarily driven by increased sales of SDC clear aligners, higher discounts, and unfavorable foreign exchange rates. Q2 Invisalign ASPs were up sequentially approximately $15 from Q1 to $1,285, reflecting price increases and favorable foreign exchange, partially offset by increased promotional discounts. On a year-over-year basis, Q2 Invisalign ASPs were flat, reflecting price increases offset by increased promotional discounts and unfavorable foreign exchange.
For the second quarter, total Invisalign shipments of 231.9 thousand cases were up 11.5% sequentially, driven primarily by our international doctors and North American orthodontists. Year-over-year, Invisalign case volume growth was up 31%, driven by growth across all regions, as well as expansion of our customer base, primarily from Asia Pacific. For North American orthodontists, Q2 Invisalign case volume was up 10.5% sequentially and up 34.5% year-over-year. For North American GP dentists, Invisalign case volume was up 9.9% sequentially and up 18.9% year-over-year. For international doctors, Invisalign case volume was up 13.6% sequentially and up 37.4% year-over-year. Our scanner and services revenue for the second quarter was $35.4 million, up 26.9% sequentially and up 36.7% year-over-year. Moving on to gross margin. Second quarter overall gross margin was 76%, up 0.1 point sequentially and down 0.2 points year-over-year.
Clear aligner gross margin for the second quarter was 78.1%, up 0.2 points sequentially, primarily due to leveraging our manufacturing costs over higher volumes. Clear aligner gross margins were down 0.5 points year-over-year, primarily due to lower ASPs. Scanner gross margin for the second quarter was 56.7%, up 0.6 points sequentially, primarily due to lower services costs on our installed base and partially offset by lower ASPs. Scanner segment gross margin was up 3.1 points year-over-year, primarily a result of lower service costs and product mix shift to our lower-cost iTero Element scanner. Q2 operating expenses were $187.3 million, up sequentially by $13.4 million or 7.7%, primarily related to increased employee headcount, marketing programs, including our advertising campaigns, key customer events, and international commercialization efforts.
On a year-over-year basis, Q2 operating expenses were up 33.7%, reflecting increased headcount and continued investment in our go-to-market activities critical to the growth of the business. Our second quarter operating margin was 23.4%, up 3.5 points sequentially and down 0.8 points year-over-year. The sequential increase in operating margin relates primarily to increased clear aligner volume. On a year-over-year basis, the decrease in operating margin primarily reflects higher operating expenses as we invest in headcount, geographic expansion, and new products in order to increase adoption and accelerate the growth of our business. With regards to our second quarter tax provision, our tax rate was 17.7%, which includes $1.1 million in excess tax benefits and is down by approximately 5.5 points compared to prior year, primarily due to a favorable resolution of foreign jurisdiction unrecognized tax benefits during the quarter.
We supply aligners to SmileDirectClub. Therefore, revenue and costs for this activity are included in our operating profit and reporting results, although they were immaterial to the company this quarter. Additionally, we report our share of SmileDirectClub's losses below operating margin and our tax provision and is entitled "Equity in Losses of Investee, Net of Tax." Our Q2 loss net of tax was approximately $2.2 million, or $0.03 per diluted share. Second quarter diluted earnings per share was $0.85, flat compared to Q1 and up 37% compared to prior year. Moving on to the balance sheet. As of the second quarter, cash equivalents, and marketable securities, including both short and long-term investments, were $676.6 million. This compared to $644.2 million at the end of Q1, an increase of approximately $32.4 million, primarily related to net income growth and our collections efforts.
Of our $676.6 million of cash equivalents, and marketable securities, $218.4 million was held by the U.S., and $458.2 million was held by our international entities. Q2 accounts receivable balance was $291.7 million, up approximately 9.2% sequentially. Our overall DSO was 74 days, down three days sequentially and up 10 days year-over-year. The year-over-year increase is a result of our ERP and other related systems implementation last July, which have impacted our timing of our customer collections. As we work through these changes, we anticipate that our DSOs will continue to decline over the next few quarters. Cash flow from operations for the second quarter was $110.5 million, up $34.3 million compared to prior year. Free cash flow for the second quarter, defined as cash flow from operations less capital expenditures, amounted to $92 million.
Capital expenditures for the second quarter were $18.5 million, primarily relating to building improvements, equipment purchases for additional manufacturing capacity, as well as our global expansion efforts. During the second quarter, we paid $50 million under an accelerated stock repurchase plan, ASR, in which we received an initial delivery of approximately 300,000 shares of common stock. The final number of shares repurchased will be determined at the completion of the ASR based on Align's volume weighted average stock price during the term of the ASR, less an agreed upon discount. There remains approximately $250 million available for repurchases under the existing stock repurchase authorization. As Joe mentioned earlier, we have purchased an additional 2% of SmileDirectClub for $12.8 million, which brings our total ownership to 19%, and we extended SDC's line of credit from $15 million to $30 million. All other terms remain the same.
With that, let's turn to our Q3 outlook and the factors that inform our view, starting with the demand outlook. For our international markets, expect Invisalign volume to be up sequentially, which reflects continued strong growth in APAC, partially offset by summer holidays in EMEA. For North America, expect Invisalign volume to be flat to slightly down sequentially, reflecting stronger teen volume for orthos, offset by GP dentists who typically have less days in the office and lighter patient traffic during the summer. For our scanner business, we expect revenues to be up sequentially. With this as a backdrop, we expect the third quarter to shape up as follows. Invisalign case volume is expected to be in the range of 231,000-234,000 cases, up approximately 30%-32% over the same period a year ago, reflecting continued strong demand, including summer seasonality in North America, ortho, and Asia Pacific.
We expect Q3 net revenues to be in the range of $355 million-$360 million, an increase of 27%-29% year-over-year. We expect Q3 gross margins to be in the range of 74.7%-75.7%, reflecting higher ASPs, partially offset by higher expenses as we globalize our treatment planning operations. We expect Q3 operating expenses to be in the range of $184.5 million-$187.5 million, relatively flat on a sequential basis. Q3 operating margin should be in the range of 22.7%-23.6%. Our effective tax rate, including an excess tax benefit of about $1 million, should be approximately 21%. We expect a $2 million loss related to our share of SmileDirectClub, and diluted shares outstanding should be approximately 81.8 million, exclusive of any share repurchases. Taken together, we expect our Q3 diluted earnings per share to be in the range of $0.78-$0.81.
In addition, as we continue to operationalize expansion efforts, we expect CapEx for Q3 to be approximately $70 million-$75 million, which includes purchasing a new facility in Costa Rica for $26.1 million. With that, I'll turn it back over to Joe for final comments. Joe.
Thanks, John. Overall, we're pleased to see the first half of the year off to such a strong start. Many of you have already recently thought of a question about us being at a tipping point, and I'm sure we'll get that question following today's call. Frankly, we think it's too early to tell. The growth we're seeing in our business is better than we expected and reflects progress in several areas, including clinical efficacy, sales coverage and support models, customer engagement, and demand generation and patient capture. We believe it also reflects a healthy underlying market with solid patient traffic and a significant increase in direct-to-consumer programs by us and others. There's still a lot of work ahead as we move toward our goal of replacing metal braces and making Invisalign the standard of care in orthodontics.
We know there will be challenges, and we aren't drawing a straight line up and to the right at this point, but we are confident in our ability to drive this industry forward and transform it from an outdated analog process to a fully digital system. Thanks for your time today, and we look forward to your questions.
At this time, we will be conducting a question and answer session. If you would like to ask a question, please press star one on your telephone keypad. A confirmation tone will indicate your line is in a question queue, and you may press star two if you would like to remove your question from the queue. For participants using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. One moment, please, while we poll for questions. Our first question comes from the line of Robert Jones of Goldman Sachs. Please proceed with your question.
Great. Thanks for the questions. Joe, the teen growth the past couple of quarters now, the acceleration has been noticeably pretty steep. Understanding that it's obviously not one factor that's driving this acceleration, is there any couple of areas that you would point to specifically? Anything that you could just help us get our head around what you think is most resonating with practitioners in the marketplace?
Bob, from a teen standpoint overall, I'd just focus on North America for a second. We mentioned last year when we put our plan together that we would have a strong focus on teens as we go into the second quarter of this year, because it's the teen season for North America. What we started that program off with is we had several programs in North America just to get doctors ready for this program overall. Next Level Partnership, a program we call IMOP, some specific things that really focused on teens to get that base ready. Then we started to really unleash the communications part of this, the $14 million or so that we're moving in consumer advertising to do that.
I think when you look at the first half and those two kind of simultaneous actions, that's been really one of the biggest underlying drivers of North America to make that to really go. That along with our ad campaigns and everything else we've put in place that are much more specific these days in the sense of how we go to market. You see how we're working both the teen channels and the moms channels from a marketing standpoint also. It's just a much cleaner, more specific approach to teens that includes a real sales effort with our doctors and a real strong customer-patient facing piece with moms and teens.
No, I appreciate all that. I guess just shifting over, I had a question on North American GPs. I know the focus has been on orthos, and rightfully so, but noticed that the North American GP saw a significant step up from the level of growth you had been seeing. Anything that you would talk to there specifically that you think would attribute to the step-up in growth we saw in the quarter?
Yeah, I'd say two major variables, Bob. One would be just media spend. We've had a significant increase in media spend itself, and we have seen a strong correlation between media spend in the U.S. and a GP increase. Then secondly, like our Lite product that we introduced in the second quarter with the GP segment, we're more and more targeting that segment with easier products that are more simple for them to deliver to the marketplace. I'd say media spend and some specific products have really helped in that sense.
Got it. Makes sense. Thanks for the questions.
Okay. Bye. Thanks.
Our next question comes from the line of Brandon Couillard of Jefferies. Please proceed with your question.
Thanks.
Hi, Brandon.
Good afternoon. Hey. Joe, on SmileDirectClub, could you give us the sense of how much of the manufacturing volume you did for them in the first quarter? I'm just curious why the additional equity investment couldn't have been larger, and if that was even an option for you guys.
Well, we mentioned it in my briefing that we're doing one-third of their cases right now. It's still not material in that sense, Brandon. We just wanted to give you just an idea of where we stand overall. They do still two-thirds of their volume. As far as the percent equity, it was just an opportunity we had. We work closely with David and his team at SDC. That equity was available. We're pleased with the relationship. We thought that was just a great next step for us in that sense.
On Teen, I'm curious if the second quarter was material ahead of where you thought it would be in terms of volumes. Would it be reasonable to expect a further acceleration in the Teen growth rate in the third quarter, given that the ad campaign didn't really start until mid 2Q?
Jon.
Yeah, I'll take that one, Brandon. This is John. What we saw with Teen said helped us contribute to some of the upside that we saw in the second quarter for some of the volume. It's part of the overall campaign that we have, where we're spending additional this year. Our guidance in Q3 reflects all those factors into our numbers.
Thanks. Then the $14 million for the ad campaign, was that all absorbed in 2Q, or is there some that rolls into the third quarter as well?
That's throughout the year. I mean, primarily where a lot of that hits in the second and third quarter, but there's additional spend throughout the year.
Got you. Thanks.
Thanks, Brandon.
Our next question comes from the line of John Kreger of William Blair. Please proceed with your question.
Hey, John.
Hi. Thanks, [Reem]. Hey. Another just quick follow-up on SmileDirect. When you did that deal, I think you said that when incoming case volume came in, if the case was too complicated, it would sort of get pushed into Invisalign. Is that the case? If so, what have you learned? What sort of percentage of case volume ends up driving into Invisalign?
You know, John, it's Joe. We haven't had terrific conversion rates in that sense. We've learned a lot. We tweak that model all the time is the patients of SmileDirectClub service, they have a certain price point in mind. They usually have a simple kind of an approach that they want in the sense of correcting their smile. They need to be dealt with really quickly. In other words, when those patients are interested, moving them into an orthodontist in this case, or a GP that wants to do that, it has to be done quickly and concisely because these patients, they're just different than the normal patients that we work with. We keep honing that model. We've had some success. We keep building on it. We think, in the future, as we put this thing together, we'll have a much better yield.
Great. Thanks. Joe, I think you said, you're just getting started on India. Can you talk a little bit more about that market, maybe try to size it for us and just kind of lay out what sort of strategy you're thinking about to ramp it over time?
Oh, India. You said India, John?
Yeah, India.
Oh, India. Oh, that's India. I'll go back to India again this year. I was just there last year. What we do when we go into a country like that, John, is you really do this by city, and you go in the city, and you recruit doctors, and you just begin to ramp up in those specific cities. You find great doctors in the sense of peer-to-peer, being able to one doctor to teach another. You look at this as almost a city-by-city effort in India. We'll take obviously the biggest and the most prosperous cities first. We work out from there. We're really in our second year of this in a big way. We're reaching our goals. The business has been growing pretty rapidly in that sense, and this is a model we really follow all over the world.
When you get to India, you just have to make sure that you approach it in an Indian way. As an example, what an Indian way is, they often don't want to buy our scanners. What we have is a scanner that's often a few of them in a city on a truck that they rent, and we move them in almost daily into different offices. They line up patients to do scans. We just acclimatize, to use that word, to the marketplace and keep working that. We're excited about it, and we feel very confident of our long-term trend there.
Great. Thanks much.
Yeah. Thanks, John.
Our next question comes from the line of Erin Wright of Credit Suisse. Please proceed with your question.
Hi. Good afternoon. This is Adam Krasner on for Erin Wright. I just wanted to touch on the strength in doctors trained in the quarter. To try to get a sense of what the typical ramp is for new doctors who are added to get up towards the average level of productivity.
Average ramp of a new doctor?
Right. That probably didn't contribute very much to the record shipments in the quarter, the fact that you added so many new doctors, or did it?
Where we're having a lot of expansion opportunities, obviously outside the U.S., where we're adding new doctors, you're seeing a lot of the growth outside the U.S. being driven by adding new doctors. In the U.S., and in particular, in both our ortho and GP channel, you're seeing growth by utilization predominantly. We saw both as a driver in the GP channel.
Thanks. Do you have a sense of, I'm looking at the statistic in the press release of 123,000 doctors trained worldwide. Is there a sense for what the total size of that market is to get a flavor of kind of how far the penetration is as of now?
Yeah. When you look at the total size of the number of orthodontists and general dentists, we can follow up with you if you want more detail. In the U.S., there's roughly 140,000, 150,000 GPs and orthodontists, roughly 10,000. Outside the U.S., the market's substantially larger. In Europe, there's probably 300,000. In Asia Pacific, there's probably twice that. It's huge. Four to five times that. We're happy to provide more stats for you offline.
Great. Thanks a lot.
Thanks, Adam.
Our next question comes from the line of Steven Valiquette of Bank of America Merrill Lynch. Please proceed with your question.
Thanks. Good afternoon, Joe and John. Incredible results.
Hey, Steve.
As we've been doing work and just talking to more practitioners, we're getting even greater appreciation for the SmartTrack aligner material. I guess with the disclosure back in May that you got the two patents issued, just curious to get more color around the patent protection on that material, because I think it is a critical part of the overall picture. The biggest thing is these seem to be the primary patents to protect that material. I just want to confirm that. Then one was filed in 2012, the other one in 2016. Really, I guess what I care about more than anything else is, what's the expiration date? How long will you get protection on this material? Is it 20 years from the date of filing or 20 years from date of issuance? I just forgot the details around that. Yeah. Thanks.
Steve, it's Joe. Its date of filing is at 20 years. It's a multilayer material. We do have patent protection on it now. The vendor that we use on it has a certain amount of restrictions in the sense of dentistry and where it can be used, but also has patents on process and all and how this is put together. It's not an easy material to do in that way. Just look at it as from date of filing and all, we have a significant number of years that the SmartTrack continues to be an Invisalign and an Align material.
On the simple math, you should be good till about 2032 or so. Is that about right?
We'll both be on the beach by then.
Okay. Okay. Just wanted to confirm that. Thanks.
Thanks, Steve.
See you, Steve.
Thanks, Steve.
Our next question comes from the line of Jonathan Block of Stifel. Please proceed with your question.
Hi, John.
Thanks. Hey, guys. Joe, you'll be on the beach then. I still think I'll be at this desk right here. Maybe just some thoughts on 2017. Maybe I missed that, John, from your commentary or even the slides. I think last quarter, you talked about the high end of the 15%-25% revenue growth and op margin in and around 23%. Are there revisions to either of those numbers that you gave last call for 2017?
Well, what we've guided to Q3. You could see that from an overall guidance standpoint. That's the update, John, that we have after we've seen Q2. From there, you can probably do the math to get an overall from a year standpoint. At least for the Q3 guide, we feel comfortable with what we're seeing so far, and that's what we ended up forecasting.
Okay. I got it from a math perspective. I guess just to push you a little bit, notably on the revenue, you blow out two Q, you guide three Q ahead. Obviously, if you just keep the 25% for the year, it would imply a bigger step down for four Q. I guess you're just sort of saying go with what you guys gave last quarter. There's no official change to those numbers.
That's exactly what you're hearing, John.
Okay. Fair enough.
He said it better than we wanted to. That was really good.
All right. Just any thoughts on the ASP. John, if you could remind us, I believe you took price in the U.S. earlier in the year. Did you take price internationally more recently? The euro for the first time in several quarters has sort of flipped and should be a tailwind. Maybe when we think out on the Invisalign ASP in the back half of 2017, is there any direction you can give us there? Thanks, guys.
Yeah, you're right, John. In North America, we took a price increase in April, and in EMEA, it came in July. The price increases have happened. As we look at what's happening for the next quarter, we're pretty much expecting price to be flat to this quarter. We have price increases. We also have other pressures and FX unfavorability as well. You net all that out, and third quarter, we expect ASPs to be flat.
Okay. Thanks so much, guys.
Hey, John. Joe again. On your question on third quarter, fourth quarter, I think the best way to take what we're saying is we're not calling a step down in the fourth quarter. We're just giving you good clarity on what the third quarter is, because that's what we have clarity on now.
Understood.
Okay.
Understood. Thanks, guys.
Yeah.
Our next question comes from the line of Jeff Johnson of Robert W. Baird. Please proceed with your question.
Hey, guys. Good afternoon.
Hey, Jeff.
Just on the ASPs, John's question just reminded me as he was asking about euro flipping and then maybe getting a little benefit over the next few quarters. Hey, John, as we get into 2018, are we inching closer at all to any release of those additional aligner reserves where that could theoretically start to help ASPs at all? Or is it still too early for thinking about any ASP benefit from those kind of factors?
Jeff, it's too early. It's part of our overall plan, where we have that premium price product that has the additional aligners. That's built into the plans that we have and the pricing that we have. There's no extra reserve coming back related to that. It's just part of our overall plan from a strategic standpoint, as well as what we're thinking from an ASP standpoint.
Fair enough. Joe, I found your comments interesting at the very end of the call, just maybe a note of caution. Obviously, I know as the numbers go up, so too do expectations. I get trying to keep everybody a little level-headed here. I think in past calls you've also talked about your confidence in clear aligners eventually replacing brackets and bands, and why would you want metal on your teeth and things like that. You had a slightly different message this evening. Is there anything looming over the next few quarters that has you maybe a little worried or you're just wanting to make sure we all account for titrate in our models, anything like that?
I'm not trying to give you any kind of warning or anything like that, Jeff. I have all the confidence in the world, like I said in my final comments, that we'll complete this mission of eliminating wires and brackets with a digital system with plastic. I get questions all the time, as you can guess, when you see these kind of growth rates about if we are at a tipping point in this business. I think we all know about the whole term tipping point and what it would mean. All I was trying to get across is I don't think you can take two quarters and draw a line through as a tipping point. Don't mistake in anything at all that there's something that we see that would in some way shake our confidence in what we think we can do.
All right. Fair enough. I appreciate it, guys.
Okay, Jeff.
Our next question comes from the line of Richard Newitter of Leerink Partners. Please proceed with your question.
Hi, good afternoon. This is actually Ravi in for Rich. Thank you for taking the questions. Just a couple, if I can start just with the scanner business. You guided, I think I heard, up sequentially 3Q. Can you give us a little bit of color in terms of what kind of penetration into your adoption base are you seeing here? If we use a proxy of about 34,000 doctors that you shipped Invisalign product to last year, can you help us kind of understand what the runway here is for additional docs picking up this product? Secondly, just going to take a stab at the SDC volume. I'm guessing it may be about 2,000 cases in the quarter. Any direction on that? Thanks.
Ravi, on the scanner penetration, you have to look at it as almost two separate markets. There's the orthodontic market and the GP market. I'm not sure exactly how far penetrated we are in the orthodontic side, but I'd say what you have to look at is often when a doctor starts to do more and more Invisalign, they want an iTero scanner per chair. You really can't look at it as a unit per doctor in that sense. You got to look at it as a unit in the sense of number of chairs in that office. I'd say, obviously we have a higher penetration rate right now on the ortho side than we do on the GP side. But with, like Shirley quoted a moment ago, at 150,000 GPs in the United States, we haven't really even begun in that sense.
That type of scanner has a good balance between Invisalign and being able to do restorative applications, too. If you're worried about a max out on penetration, that's not necessarily in the way that we're thinking, certainly on a yearly basis. On the SDC volume piece, I don't think we've given out that data. Don't think we necessarily want to do that both for our sakes and SDC's, too.
Great. If I could just get one more on just OpEx and investments. Some of the calls that we've spoken to them is that dentists are pretty favorable about maybe shifting more of their cases towards Invisalign. Can you just talk a little bit about kind of the TFM, how that's kind of playing out as you've brought it to the U.S. and whether you feel like you need to expand and doing more investments to support further conversion of these cases to Invisalign? Thanks.
Ravi. First, I think your question's a great question. It's just from a penetration standpoint, how do you drive more of it and what you do. TFM is one of it. We've really rolled that out strongly in North America this year. Our numbers are tremendous in the sense of when you have a customer who wants to dedicate time to really learn. Again, think of TFM as kind of a learning curve. As you have primarily an analog process and your whole office has worked around gluing wires and brackets and adjusting emergencies to people's teeth and what's it look like when you go to more of a digital format. At the front end of the digital system, how you work with ClinCheck.
These are doctors that come forward and say they want to devote 90 days, 120 days of just learning, to spending time to learn how to really ramp up in a digital format. It works well. It's self-selected in that case because doctors come forward that really want to do that and spend their time. I'd also say the other thing I've learned in this job over the last two years is how important peer-to-peer is from a growth standpoint, is having really good, strong doctors that can communicate to other doctors about how to use Invisalign. We see this not just in North America, we see it all over the world as critical. We've ramped up new programs like IMOP and some other things that have just really helped in that sense.
Both across the orthodontic community and also across the GP community to do it though. Those are the two big programs I'd say we use to address the question that you have about how you ramp up doctors.
Great. Thanks. If I could squeeze one last one in, just given the landscape in the dental industry out there right now and your cash balance, any type of color on what kind of acquisitions that you guys would be potentially interested in beyond the, I appreciate that you've been kind of building out the OUS kind of sales base by some of the distributor purchases. Anything beyond that we can kind of think about?
Ravi, I call that an IQ question kind of, okay? The way I'd answer that is we're in the clear aligner business, anything that helps us to sell more clear aligners directly that doesn't have to be explained would be in our range. That's why we have a scanner business. We have a scanner business not from a diversification standpoint. We have a scanner business because it allows us to sell more clear aligners. You're not looking, I don't care how much cash we have, we're not looking to be a diversified dental company. We do clear aligners.
Thanks. Appreciate the questions.
Thanks, Ravi. We've got one more question, operator.
Our last question comes from the line of Steve Beuchaw of Morgan Stanley. Please proceed with your question.
Thanks. This is actually Zachary Wachter on for Steve. Joe, hey. Just one question on Invisalign Go. I'm wondering if you could just update us, Joe, on the ramp there and how we should think about the timing of Go, given that the GP channel seems to be doing a bit better here. When should we think about Go making a more substantial impact?
I think, Zach, the best way to think about that is if we take a step back from this whole thing, our approach to the GP channel more and more has to be to make it easy and efficient. Go is a product like that. It's a product where you can adapt quickly from a GP standpoint. It does simple cases. Most Go's are less than, I think, 15 aligners or so. We've adopted the protocols to make it simpler for doctors to do also. I would say don't just take Go, you could look in the future. We'll have a series of more simple kind of products and systems that we'll introduce to GPs to get through. Go is just the first one of those.
That's not to downfall Go, as we learn from Go, we can continue to iterate on that product line and make new offerings. It's a big part of our GP strategy overall, is having the right product and the right kind of system that it feeds through to make it really simple for the GP docs.
Got you. Okay, just last one then. As far as the distributors that you acquired in EMEA, and [Brazil] , was there any meaningful impact in the quarter from that?
There's no material impact, and you usually don't see material impact in that for 18 months to two years.
Okay.
Next year at this time is a great time to ask that question, Zach.
Great. All right. Thanks for the question.
Thanks, Zach. Yeah, see you.
There are no further questions over the audio portion of the conference. I would now like to turn the conference back over to management for closing remarks.
Thank you everyone for joining us on our conference call today. This concludes our formal remarks. If you have any questions, please reach out to the investor relations department. Have a great day.
