dental porcelain, a type of high temperature fusion glass used in dental restorations, either jacket crowns or inlays, artificial teeth, or metal-ceramic crowns. It is essentially a mixture of particles of feldspar and quartz, the feldspar melting first and providing a glass matrix for the quartz. Porcelain, which comes in various shades, chemically and physically bonds to a metal coping and creates a tooth-colored restoration.
