A practical approach to porcelain repair

A technique for repairing fractured porcelain-fused-to-metal restorations has been presented. Mechanical retention on the coping must be created. The porcelain is beveled, acid etched, and treated with silane. The metal is masked with a mix of unfilled resin and the corresponding shade of porcelain opaque powder. Then, the surface is rebuilt with a microfilled resin (or a mixture of microfilled and composite resin) and finished by conventional methods, giving special attention to the adjustment of occlusion.
