CEREC is a dental restoration product that allows a dental practitioner 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  veneers  onlays and inlays can be prepared  using different types of ceramic material.
