Defective dental restorations: to repair or not to repair? part 2: all–ceramics and porcelain fused to metal systems

Ceramic restorations may fail in clinical service and, in common with all other types of restorations, should not normally be considered to be permanent. Next to secondary caries, as diagnosed clinically, porcelain fracture and chipping have been reported to be the major cause for the replacement of both all-ceramic and ceramic fused to metal restorations.5–7 The literature, however, includes conflicting data on the incidence of failure as a consequence of fracture or chipping.
