ABSTRACT:
The present invention is a multilayer dental system for the production of restorations which incorporates a high strength bridging ceramic core, a layer of biocompatible metal for aesthetics and encasing the abutment and a conventional porcelain top layer. The restoration is made by producing the high strength bridging ceramic core, electroforming the 24 K gold upon the core, and then completing the restoration by applying outer layers of conventional dental porcelain. A restoration of the present invention has a natural appearance, is lightweight, is highly biocompatible, does not impart thermal sensitivity, and is strong enough to be used for posterior bridgework. The system of the present invention eliminates the use of toxic alloys and will not result in unsightly oxidation, as is seen with other cast metal restorations. The high strength ceramic core does not slump with repeated firings the way cast alloys do when fired. The completed units can be bonded or cemented within the patient's mouth, and are easily handled by the dentist.
