Digital Dentistry for the Now
SACRAMENTO ? To powder or not to powder, that is the question. At least, it is for most of the clinicians who are considering buying a CAD/CAM unit. Dr. Michael Skramstad, who is a faculty member in the CAD/CAM Department at the Scottsdale Center for Dentistry told an audience at the Advances in Digital Restorative Dentistry Meeting that although there is some perception that the powdering technique needed for the Sirona system is difficult, the advantage is speed and precision.
?In a matter of seconds, you have every image that you need for a simple quadrant,? he said. ?With other units, although there is no powder, the compromise is pretty clear. You have to take multiple images per tooth, resulting a quadrant scan that can take well over a minute.? Dr. Skramstad did a side-by-side comparison of a few of the units.
He showed clinical examples of both powder and powder-free systems recorded live in the mouth to illustrate the advantage of a light dusting powder on the imaging process.
The speed advantages afforded by CEREC have led to huge gains in usage of Sirona products. One laboratory noted spikes in the number of CEREC impressions from 129 in January 2010 to more than 1200 in December 2010. Data presented by Dr. Skramstad from LMT Research Departments suggested that the number of digital impressions has been on the rise steadily and, he noted, that a survey from LMT suggested that many survey participants believe that about 31% of impressions will be digital in the next five years.
He cited another Dental Product Shopper survey that indicated that 24% of clinicians would add CAD/CAM to their practice if money was not an issue. Dr. Skramstad said that stepping into digital dentistry is an easy way to boost quality control and expand options for your patients. He noted that it enables him to take the best impressions, viewing the entire tooth, without any guesswork.
He also said a key feature of a CAD/CAM unit like CEREC is its ability to easily work with many type of materials and its use in planning even the most difficult implant cases. ?I used the term this lecture, ?Digital Dentistry for the Future,?? Dr. Skramstad said. ?It is actually ?Digital Dentistry for The Now,? because this technology is enabling clinicians and the lab to work together to instantly evaluate the impression, which decreases remakes, increases quality control, and better serves your patients.?
