Intraoral repair of metal ceramic restorations.
The porcelain-fused-to-metal restoration is and will remain one of the most common restorations in dentistry. However, with the many variables that exist in fabrication and function of these restorations, there also is a potential for failure. This failure usually involves the porcelain portion of the restoration. A simple and predictable technique is extremely advantageous in prolonging the longevity of these restorations. A combination of metal preparation along with specific porcelain treatment will result in such a repair. The specific porcelain treatment involves a combination of hydrofluoric acid etching and a saline bonding agent. The technique has been used for numerous repairs with excellent success.
