Porcelain Inlays and Overlays
A Sirona Computer, Cerec III utilizing CAD-CAM technology (computer-aided-design and manufacturing) is used to manufacture porcelain restorations. The cerec porcelain is manufactured in the Vita Factory in Switzerland and of superb quality.
This is a very conservative technique. The defective filling and decay is removed. A reflective powder layer prepares the tooth for imaging. An optical 3D camera is used to require an optical image. The restorations is designed on the computer. The milling unit mills the restorations making use of diamond coated burs. Polishing or glazing ensures a pleasant smooth natural feel. The physical properties of this porcelain is very close to that of tooth enamel. The outstanding adhesive bond between dentine and ceramic is a decisive factor for the high durability of the restoration. It not only looks like enamel but also wear at the same rate.
