CEREC 25 breaks out and laughs on day two

27 08 2010

CEREC 25Getting an early start can be a challenge at any event in Las Vegas, but the international group of attendees at CEREC 25 seemed more than up to the challenge, packing the rooms at early morning breakout sessions during the second day of this 3-day celebration of the 25th anniversary of Sirona’s CEREC CAD/CAM system.

An all-star line up of presenters offered talks on all aspects of the CEREC system and every angle of CAD/CAM dentistry. During the first sessions Dr. Michael Skramstad covered the importance of digital impressions to the CEREC Connect workflow, while Nobert Ulmer, MBA discussed marketing the digital lab. Marketing a CEREC practice was the topic covered by 1-800-DENTIST founder Fred Joyal, while Chris Leinweber, RDT, CDT, had a standing room only crowd spilling out of the doorways for his presentation on understanding the CEREC system’s nuances to optimize the fit of milled restorations.

One room over a smaller, but just as engaged crowd listed to Vanik Jinoian, MDT discuss the new VITA Rapid Layer Technology that is available for fabricating milled bridges with zirconia substructures with precisely matching ceramic layers over the top. Jinoian showed the ins and outs of the system he helped design that takes a new approach to the design of the substructures and allows the entire piece to be designed at one. The technique can be applied to designing implant abutments and crowns, as well as other restorations relying on substructures for support.

The system provides low cost restorations with a fast production time and the machined pieces are both repeatable and easily repairable, even after having been cemented in the patient’s mouth. Jinoian stressed that systems such as this which increase the productivity of dental labs is critical for the future because digital impressions and chairside CAD/CAM will continue to grow and change the way dentists use their labs.

“There is no future for crowns in the dental lab,” he said bluntly.

The second morning sessions saw overflow crowds pack rooms to hear Dr. Brian LeSage talk about prepping for CAD/CAM crowns and Dr. James Klim showcase the esthetic possibilities of CAD/CAM restorations. On the lab side of things Tom Nieting, CDT, discussed how CEREC brings labs and dentists closer together, while and engaging Eddie Corrales, CDT, explained how he is pushing using the CEREC system and digital communications technologies to provide better service for his dentist clients.

Corrales showed off a range of his esthetic work and explained that in the digitizing dental market labs need to find ways to stay valuable to dentists. For him, that path has involved handling cases via digital file transfer even before the advent of CEREC Connect, teaching dentists to be better users of their CEREC systems and even working with dentists chairside either in person or via Skype and LogMeIn computer software that allows him to take virtual control of a dentist’s CEREC computer.

“This technology is here to stay, and that’s just the way it is,” he said.

After lunch, a pumped up Sirona Chairman Jost Fischer took the stage to blaring Metallica for a brief presentation about the company where he reiterated Sirona’s commitment to remaining the leader in dental technology and touted the company’s sizable R&D commitment. That commitment is being punctuated next month with the groundbreaking of a new Bensheim, Germany facility dedicated to developing new dental technologies.

Dr. Ed McLaren presents

Next up the general sessions turned back to a focus on dentistry with Dr. Ed McLaren fighting through illness to discuss the possibilities of CAD/CAM dentistry with a focus on the materials available for use. Dr. McLaren stressed that the key to materials success or failure is not the material’s chemical structure, but rather how uniform that structure is due to the way it was manufactured.

“All of the materials are working,” he said.

However, Dr. McLaren explained the keys to successfully using the materials are the techniques with which they are used in a clinical situation. Proper etching and bonding procedures are a big key and understanding which materials fit which clinical situations can mean the difference between success and failure with CAD/CAM restorations.

Dr. Sameer Puri was the next to the stage and while he and Dr. McLaren traded friendly barbs about who drives what care, the bulk of his presentation focused on how he maximizes the use of his CEREC system for as many cases as possible. Dr. Puri said he now does all single unit posterior crowns in house and is doing many single anteriors as well.

He believes the restorations he produces with his system are better than anything he’s had before and the technology is a big marketing tool for his patients. He said the keys to his success with CAD/CAM are understanding the system and planning how he will work for maximum efficiency. While he uses the CEREC system a lot, and even for complex multi-unit cases such as the ones he presented via detailed videos and slides, he thinks it will be even more useful as in-office CAD/CAM bridges and other larger restorations become the norm.

“Pardon the pun, but we are on the cusp of something big,” he stated.

Materials was once again the subject as Dr. Dennis Fasbinder took over with a more academic presentation that focused on the properties, uses and benefits of Ivoclar Vivadent’s e.max lithium disilicate material. Like Dr. McLaren before him, Dr. Fasbinder explained how success is a technique sensitive prospect and taking shortcuts with the material weaken it structurally, and thus cut the effectiveness of its clinical use.

Both firing times and cementation of e.max restorations have an impact on how it works as a long-term restorative solution. However, Dr. Fasbinder said that when proper procedures are followed, the material offers strength and esthetics that are hard to match and makes full-contour crowns an option for numerous indications. He said CAD/CAM produced restorations are showing very positive results in clinical studies and the fabrication technology is definitely ready for more widespread use as long as materials are handled to the right specifications.

“It’s not about the box,” he said referring to the CEREC system. “The box works. It’s what we’re going to do with the box.”

The focus of the end of the day turned away from CEREC specifically, as Dr. Paul Homoly engaged the audience with humorous anecdotes that illustrated his practical advice on how to understand patients to increase case acceptance. Dr. Homoly said the way to reach patients is to gain an understanding not just of their clinical problems, but of the way those problems impact them emotionally. If a dentist presents the case as solving the deeper emotional issues caused by the clinical issues, the patient is more likely to say yes to treatment.

“Understanding what’s going on in people’s heads, that has to be analog,” he said at the open of talk before later summing things up with, “What we’re talking about is behavioral benefit.”

Comedian Dennis Miller was called upon to end the day on a lighter note. He eschewed the easier dental jokes to present his right-wing political humor to a crowd that definitely agreed with his politics and ate up his literary and referential punch lines.

The final day of CEREC 25 awaits in the morning, provided the attendees make it through one more night in Las Vegas.
