CEREC stands for Chairside Economical Restoration of Esthetic Ceramics. The method utilizes CAD/CAM or computer-aided design/computer aided manufacturing to create a crown that perfectly fits your damaged tooth. Your dentist will use the CAD/CAM technology to take images of your teeth. The images are used to create a digital model of your teeth to fit the crown. The CEREC crown is milled from a ceramic block based on the CAD/CAM model, then perfectly shaded to match your natural teeth, and bonded to your tooth. All of this takes place in one appointment.
