Cercon consists of a yttria-stabilized zirconia coping or framework that is layered with dentin, body and incisal porcelains for outstanding, beautiful metal-free aesthetics for the entire mouth. Through the addition of yttrium oxide, Cercon delivers strength and fracture toughness (900 MPa's) far beyond other known aesthetic ceramics. Using CAM technology, SDL duplicates the prep model in a modelling material and designs the restoration in wax. The wax restoration is automatically scanned using a laser system and then Cercon base banks of presintered zirconia are milled in a low-density state. These milled copings or frameworks are then sintered (1350° C) at the laboratory to fully dense restorations and then layered with low wear porcelain.
