Repair of fractured porcelain units: alternative approaches
British Dental Journal
|April 9, 1994
Abstract:
Laboratory studies have demonstrated high bond strengths between a number of resin systems to metal and porcelain, as well as to tooth substance. In circumstances where fracture of a porcelain bridge or crown has occurred, it may appear reasonable to attempt a repair using one of these systems in conjunction with abrasion of the fractured surface, although current knowledge does not allow an accurate prediction of the longevity of the repair under oral conditions.
