Salvaging a porcelain/metal bridge with a bonded porcelain-fused-to-metal overcasting.

Porcelain fractures from ceramo-metal fixed bridges often are troublesome for both dentist and patient, especially when problems occur in the anterior region. Repairing these fractures can be a challenge because the repair must be not only durable but also pleasing esthetically. While repair can be achieved with a composite resin material, matching the color and texture with the surrounding intact porcelain often is difficult and the bonding between the resin and porcelain is susceptible to marginal leakage, which may result in esthetic failure. This article reviews a technique designed to salvage a fractured porcelain-fused-to-metal bridge and return it to form and function by utilizing a porcelain-fused-to-metal overcasting.
