CEREC is an acronym for Chairside Economical Restoration of Esthetic Ceramics. Translated, it means that a dentist can economically restore damaged teeth in a single appointment using a high-quality ceramicmaterial that matches the natural color of other teeth.CEREC uses CAD/CAM (Computer Aided Design / Computer Aided Manufacturing) technology, incorporating a camera, computer and milling machine. The dentist uses a special camera to take an accurate picture of the damaged tooth. This optical impression is transferred and displayed on a color computer screen, where the dentist uses CAD technology to design the restoration. Then CAM takes over and automatically creates the restoration while the patient waits. Finally, the dentist bonds the new restoration to the surface of the old tooth. The whole process takes about one hour.Dentists no longer need to create temporaries or take impressions and send them to a lab. Because of this, the traditional second visit has been eliminated!
