Long-span, permanently cemented, multiunit prostheses that suffer a fracture of one of the porcelain facings present difficult and often embarassing problems to the clinician. Silane coupling repair systems, although quick, simple, and inexpensive, do not ensure a long-lasting result. An alternative technique involving use of a porcelain-fused-to-metal overcasting and composite resin cement is presented. The overcasting is luted to the original metal casting.
