Adhesive Monomers for Porcelain Repair.

The purpose of this investigation was to test the bond strengths of several adhesive systems intended for intraoral resin-to-porcelain and resin-to-metal bonding. All measurements were compared with resin bonded to etched bovine enamel. Based on these data and the authors' own clinical experiences, protocols for intraoral porcelain repair are presented for fractures in porcelain only, fractures with both porcelain and metal exposed, and fractures with all metal exposure.
