Case Report: Managing Complications of Feldspathic Ceramic Fractures in Zirconia-Based Crowns with Feldspathic Veneers

Abstract

This case report describes the clinical approach in managing a fractured feldspathic ceramic layer in a zirconia supported restoration with a new feldspathic veneer; minimal intervention. The case involved chipping of ceramics at tooth 1.1, in which the damaged part was removed and replaced, sparing the tooth from further intensive preparations or changes to the zirconia framework. The technique involved in the procedure include hydrofluoric acid etching, silanization, and resin cementation to foster a high bond strength. The outcomes of the study revealed an excellent aesthetic result with the replanted veneer blending properly with adjacent teeth. This case raises evidence for using feldspathic ceramics in zirconia-based restorations and demonstrates that such complications can be resolved with stability of function and esthetics. The less invasive treatment modality and the short time taken to restore the teeth suggest the feldspathic veneers as potential solution for similar long-term dentition restoration.
