Abstract:
Twenty metal ceramic crowns on upper premolars in 12 patients were purposely fractured before seating with temporary cement. The fractured crowns were repaired in situ with an experimental porcelain repair system. The initial results were satisfactory both esthetically and functionally. However, only 50% of the repairs were intact by the end of the 12-month follow-up period. The system is considered to be suitable only for intermediate repairs of metal ceramic crowns that are in occlusal contact.
