Aesthetic repair of zirconia-supported porcelain prosthesis with ceramic veneer, case report with 3-year follow-up

Abstract

Chipping is the most common complication in zirconia-supported porcelain prosthesis. If the prosthesis has ideal adaptation and there is no problem other than chipping, intraoral repair is the most practical solution for such failures. Composite resins are often preferred for intraoral porcelain repair. However, the wear and unstable colour of composite resins negatively affect aesthetics. This complication could be restored intraorally and aesthetically with ceramic veneer. This case report presents the intraoral repair of a zirconia supported Fixed Partial Denture (FPD) consisting of four units. The cohesive fracture of the ceramic material in the incisal part of maxillary right central incisor was restored with ceramic veneers. Preparation was done with a tapered, rounded end diamond bur under water-cooling. The impression was taken with elastomeric impression material. Ceramic veneer was manufactured with a leucite-reinforced glass-ceramic and cemented with light cure resin cement. Based on the three-year follow up of the performed intraoral repair, ceramic veneers have shown to be an alternative treatment for fractured FPD.
