When a dental crown is made on a slightly inaccurate model, there is higher chance that the fit of the crown will have to be adjusted a lot before it is comfortable. With traditional ways of making a model of your mouth, using impressions, molds & casting, there is the possibility of distortions occurring that make the model slightly inaccurate. Computer-Aided Manufacturing Improves EfficiencyĬAD/CAM improves the efficiency, speed & especially the accuracy of many dental restoration procedures. The diamond drill bits cut the block into the shape of the tooth determined by the 3-D design. The block is placed in the milling machine & automated drills start carving into it, like an artist carving a sculpture out of marble, but much faster. The dentist will then choose a block of ceramic or porcelain (about 1-inch square) that matches the shade of your natural teeth. Once the design is complete, the dentist sends the file to an automated milling machine that’s located right in our office. Next comes the computer-aided manufacturing. This encompasses the computer-aided design part of the procedure. By also scanning the opposing teeth, the dentist can model how the restoration will fit when your teeth come together. Using tools built into the program, the dentist then sculpts a new virtual tooth (or teeth in the case of multiple-tooth restorations). The digital scan is instantly transmitted to a specialized computer program where a 3-D model of your teeth is automatically generated. COVID-19 Sterilization & Patient Safety.
