What is a porcelain-fused-to-metal dental restoration?

A type of dental restoration is porcelain-fused-to-metal, which provides strength to a crown or bridge. These restorations are very strong and durable.

The combination of porcelain bonded to a supporting structure of metal creates a stronger restoration than porcelain used alone. More of the existing tooth must be removed to accommodate the restoration. Although they are highly resistant to wear, porcelain restorations can wear opposing natural teeth if the porcelain becomes rough. There may be some initial discomfort to hot and cold. While porcelain-fused-to-metal restorations are highly biocompatible, some patients may show an allergic sensitivity to some types of metals used in the restoration.

A porcelain fused to metal restoration is a cap/crown that has a metal foundation upon which porcelain is baked/fused. The metal may be base metal, noble metal (often platinum palladium alloy) or high noble metal with a significant percentage of gold. The porcelain is available in a wide variety of colors so that the color can be blended and matched to the color of the adjacent teeth. Of course, if multiple teeth are being crowned the patient and dentist may decide to alter the natural color with the porcelain restorations.
