- Title
Clinical techniques for intraoral repair of fractured porcelain when metal is exposed.

- Abstract
The article provides information on the problem of fracture of porcelain from metal-ceramic restorations. According to a research, It is stated that strong bonds can be formed between composite resin and dental porcelain when the porcelain is etched with acidic fluorides and subsequently treated with silane coupling agents. The fracture of porcelain from a metal-ceramic restoration is said to be of complicative nature because there has been no reliable method of forming a strong bond between resin and metal. A case study has also been discussed wherein a clinical technique, employing new dental technologies, was experimented on a 55-year-old man who presented with a complete loss of porcelain from the mesiofacial surface of a porcelain-fused-to-metal crown.
