The term CAD/CAM is literally a shortening of Computer-Aided Design (CAD) and Computer-Aided Manufacturing (CAM) aka “a crown in a day.” The CAD/CAM machine provides the dentist with restorations, which are milled from blocks of white composite resin or porcelain, matching the shade of the restored tooth. Once the treated tooth is shaped and prepared, an image is taken of this defected tooth. The image then provides the data for a computer and the software is used to create a porcelain or resin composite piece for the defect, essentially creating a virtual restoration.
The software then sends this virtual data to a milling chamber in the lab where the dental restoration is carved out of a solid block of composite resin or porcelain. The resultant restoration can then be adjusted in the patient’s mouth and cured/bonded in place. Following acid etching of both, the underside of the restoration and the topside of the tooth itself (which increases surface area on both opposing surfaces), composite resin materials are then used to fuse the resultant restoration to the tooth, completing the restoration process.
At Dr. Gowd’s Dental Hospitals, we use Cerec 3D technology. Cerec 3D is the state of the art technology that makes it easy for the dentists and patients in making all kinds of restorations with micro millimeter accuracy in a span of few hours. Clinical applications include metal and all-ceramic crowns and bridges, onlays, inlays, and veneers, as well as a variety of implant restorations. The system can also produce custom implant abutments in both zirconia and titanium.
