Cercon® Ceram S Porcelains (K022796) PREDICATE DEVICE:

DEVICE DESCRIPTION: The CERCON® CERAM EXPRESS Ceramic System consists of a dental ceramic veneering material developed for veneering zirconium oxide substructures for fixed prosthodontics devices that include both anterior and posterior crowns and bridges. The modified device is a glass/glass-ceramic mixture used to veneer zirconia substrates in a medium-pressure. lost-wax injection molding (pressing) process. The modified device consists of a translucent material and an opaque material.

INTENDED USE: Designed for use on zirconia (zirconium oxide) in single tooth or bridge type restorations. Applications include tooth anterior and posterior locations.

TECHNOLOGICAL CHARACTERISTICS: CERCON® CERAM EXPRESS Ceramic System represents a modification to Cercon® Ceram S Porcelains (K022796). Changes have been made to the device's formulation, material form, and processing technique.

All of the components found in CERCON® CERAM EXPRESS Ceramic System have been used in legally marketed devices.

We believe that the prior use of the components of CERCON® CERAM EXPRESS Ceramic System in legally marketed devices, the similarity in the formulations between the modified and the marketed device, and the data provided regarding the modifications to the marketed device support the safety and effectiveness of CERCON® CERAM EXPRESS Ceramic System for the intended use.
