CEREC is a dental restoration product that allows Dr. Yamada to produce an indirect ceramic dental restoration using a variety of computer assisted technologies, including 3D photography and CAD/CAM. With CEREC, teeth can be restored in a single sitting with the patient, rather than the multiple sittings required with earlier techniques. Additionally, with the latest software and hardware updates, crowns, onlays and inlays can be prepared, using different types of ceramic material.
The cavity preparation is first photographed and stored as a three dimensional digital model and proprietary software is then used to approximate the restoration shape using biogeneric comparisons to surrounding teeth. Dr. Yamada then refines that model using 3D CAD software. When the model is complete a milling machine carves the actual restoration out of a ceramic block using diamond head cutters under computer control in our own office. When complete, the restoration is bonded to the tooth using a resin. CEREC is an acronym for Chairside Economical Restoration of Esthetic Ceramics.
