Abstract
A dental restoration comprises a ceramic core material having a thin metallic layer disposed on the interior surface of the ceramic core to provide integrity to the ceramic core, eliminate bonding between the ceramic core and the patient's tooth or teeth, and provide an impervious layer on the ceramic interior to reduce infiltration of fluids into the ceramic and reduce cracking of the ceramic restoration. The metallic layer may comprise a metal, alloy or metal-matrix ceramic material. A strong, crack-resistant ceramic restoration is provided having highly aesthetic properties.
