Guaranteed. Really?!

3M ESPE makes a bold statement in the digital impressioning category by not just touting the technology behind the Lava C.O.S., but guaranteeing fit on all Lava C.O.S. restorations.

The details

All approved indications for the Lava C.O.S. are covered by the guarantee, including single or multiple crowns, inlays, onlays, veneers, seated implant abutments and bridges up to 4 units. Doctors can take advantage of the guarantee if the restoration does not fit the patient and isn’t seated and the restoration fits the SLA model provided to the doctor’s lab. Labs can receive compensation if the restoration was made using approved processes and fits the unmodified SLA model.

If the doctor chooses not to seat a restoration for reasons of fit, after verifying eligibility, 3M ESPE will:

  • Issue the practice credits for two case fees
  • Compensate the lab $100 to help defray the remake cost
  • Provide an analysis about the reason(s) for the misfit to the doctor and lab

Eligibility applies to new certified doctors of practices in good standing, as well as trained and certified laboratories in good standing producing restorations for eligible doctors only. The one-year duration of the guarantee begins on the practice’s certification date.

The data

brought to you by THE DENTAL ADVISOR

Through our new publishing alliance with THE DENTAL ADVISOR, we were made aware of a study which confirms 3M’s commitment to a guarantee of the Lava brand zirconia when paired with the C.O.S. Here, we’ll share an abbreviated version of the findings from their recent report.

THE DENTAL ADVISOR has been reviewing all major CAD/CAM systems clinically for over a year now and has been an excellent resource to practicing dentists. For the complete clinical protocol and results, as well as the latest in CAD/CAM research, visit dentaladvisor.com/clinical-evaluations/cad-cam-corner.shtml

Clinical protocol

Sixty-one patients were treatment planned for full-coverage restorations, consented and enrolled in the study, and scheduled. A total of 63 teeth were prepared. In addition to the Lava C.O.S. scan, upper and lower impressions along with a bite registration, were taken on each patient.

Two zirconia copings were fabricated for each prepared tooth. The crowns were shipped to Enspire Dental where they were evaluated; the best crown was seated by one of the three dentists taking part in the study.

Results

One hundred twenty-six crowns were fabricated for 63 prepared teeth. Eighty-one percent of the crowns were cemented with a self-adhesive resin cement.

The mesial and distal contacts were consistently more accurate on the crowns designed using Lava C.O.S. data than on the crowns designed on the impression model. Several of the crowns in the study were second molars—the last tooth in the arch— in which case the distal contact was rated perfect by default. In the areas of “Rocking” and “Fit,” crowns fabricated using Lava C.O.S. data were better. The margins—mesial, buccal, and lingual—were perfect more often on the SLA model made from the digital impression. In the case of the distal margin, the impression and the Lava C.O.S. crowns were rated essentially the same. Occlusion was rated significantly better on the Lava C.O.S. crowns, with 74% vs. 46% being perfect and with 18% of Lava C.O.S. crowns vs. 48% of impression crowns being too high.

Because of these differences, 71% of the Lava C.O.S. crowns and 29% of the impression crowns were cemented.


Conclusions

Sixty-three percent of patients preferred the scan. Scan times were as fast as or faster than taking an impression. The overall fit of the Lava C.O.S. crowns was superior to that of the impression crowns.

In early January, 3M ESPE announced that moving forward it would ensure the accurate fit of restorations created using its Lava™ Chairside Oral Scanner C.O.S., with a one-year guarantee for new doctors. The program is intended to highlight the system’s accuracy and demonstrate 3M ESPE’s commitment to customers who purchase this powerful technology.

As the digital impressioning field continues to grow—with several new competitive products slated for launch this year—Dental Products Report decided to follow-up with 3M ESPE about what this campaign means for the company and what it means for the end user. The following Q&A is excerpted from a phone interview between Thais Carter, Editor in Chief for DPR, and Chad Naughton, 3M ESPE’s marketing communications supervisor for Lava C.O.S.

DPR: After the “soft launch” of the Lava C.O.S. at the 2008 Chicago Midwinter meeting, you launch this “Guaranteed Fit” campaign leading up to Midwinter 2010. To those on the outside, that seems like a huge leap in a very short time. The main question is: Why?

When we launched this, it was all controlled and we did it methodically…opening up different areas of the country a bit at a time. We weren’t nationwide until the second half of ’09. Prior to that, it never made sense to do national marketing. We’ve had tremendous progress and what we’ve seen over the course of the last year is tremendously successful integration with our core group of customers. One thing that was clear was the remake rate was radically less than it was with traditional materials. We’ve always been proud to stand behind our products, and in the case of the Lava C.O.S., that evolved into a guaranteed fit.

DPR: Why take such a dramatic stance instead of just promoting the lower remake rate?

When you ask doctors about digital impressions, they see this is where dentistry is going. They know the technology is remarkable, but many don’t feel ready yet. One of the things we thought we could do, because we have confidence in our process and system—which leads to greater accuracy from the very beginning—is to guarantee fit for new doctors.

DPR: How would you describe the Lava C.O.S.’s standing in the current field of digital impressioning systems?

It’s simple. Our approach at 3M ESPE is to enter a category to be No. 1. We were a couple years behind Cadent in terms of offering a stand alone system, and CEREC, of course, has been around for many years, but only as a chairside system. We see opportunity and looking toward the future, we know we want to win.

DPR: What is it about your technology that you think offers you a competitive advantage?

Accuracy and potential. Every other system uses point and click technology which has been around for more than 20 years and we are just beginning to harness the power of our “3D-in-Motion” technology. For comparison, every time you take a picture with point and click you capture 1 3D data set. For every second you are in the mouth with our system it captures 20 3D data sets.

DPR: Are you worried about having to compensate for people not using the technology correctly?

One of the things we like to say is, we can’t make a bad dentist a good dentist, but we can make a good dentist a better dentist. The vast majority of customers are good dentists. What’s great about guaranteed fit is that if you have a challenge along the way or something doesn’t work, we try to capture that up front and correct it right away. We’re not just saying we’re going to compensate you for the lack of fit, but we’ll find out what was wrong and how to fix it moving forward. We don’t have to do it a lot, but that’s the promise we want to deliver.

DPR: How do you define success for this type of ad campaign?

At the end of the year, we’re all judged by making sure that we sell the units, but a great part of this campaign is making sure the doctors who do come on board have alleviated the fear. We want them to be 100% satisfied with their decision and 100% excited with where this is going.

DPR: Is there anything that worries you about the growth of the category?

Well, my concern is that we’re going to end up seeing a lot of “me too” companies. We try to emphasize to potential customers that when you are looking at a fundamental shift in how you do business, you don’t want someone who’s just going to sell you a system, but someone to partner with you.

DPR: What closing thought would you like to leave readers with?

We are not just guaranteeing fit of the restoration, but also standing behind the real benefits our doctors have told us about: Productivity, improved patient experience, improved communication with their labs and even a more engaged staff.
