I 21 feature _ interview I CAD/CAM 1_2011 streamline collaboration between the dentist and the DT. The resulting workflow is quicker and simpler. _How have you measured this? CERECConnectfacilitatesanall-digitalwork- flow, from the initial impression to the finished restoration. In the case of conventional tray impressions, numerous intermediate steps are required in order to create a working model. Therefore, considerable scope for error exists, beginningwiththeinitialimpressionandending with the fabrication of the stone model. CEREC Connect reduces this process to three simple steps: the application of CEREC Optispray (Sirona),theacquisitionofthedigitalimpression via the intra-oral camera, and the completion of the order form on the computer monitor. With a single click of a mouse, I can send the virtual model data to the DT in just a few seconds. This eliminates the shipping times to and from the dental laboratory. Afurtheradvantageisthattheintra-oralscan reproduces the situation in the patient’s mouth with a high degree of accuracy. This eliminates any deviations attributable to the physical properties of the silicone impression compound. In the final analysis, CEREC Connect rules out potential errors and hence benefits all those concerned, above all, the patient, who receives a perfect dental restoration. _How have patients reacted to this new im- pression-taking procedure? My patients have found this new impression- taking procedure with the intra-oral camera much more pleasant. And they have given voice to this clearly. Most patients are horrified at the prospect of having a conventional impres- sion tray in their mouths, which can take up to four minutes until the impression compound has finally set. This step has now been elimi- nated, much to the relief of my patients. With the aid of the intra-oral camera, I can acquire practically contact-free scans of the prepara- tion, antagonist and bite situation. The ca- mera only needs to be placed on the teeth briefly. This is quick and does not cause any dis- comfort. _Which restoration types do you delegate to CEREC Connect? I delegate all restorations in excess of a certain size to my dental laboratory. Smaller restorations such as inlays, partial crowns, crowns and small-sized bridges are fabricated in-house on the CEREC system. In the case of complex work, I rely on the DT’s expertise.
