A case of esthetic improvement of a missing maxillary anterior tooth and discolored teeth with zirconia prostheses

Abstract

Patient: A 39-year-old male presented with masticatory dysfunction caused by occlusal pain in the maxillary right central incisor. The tooth was diagnosed as non-restorable and was subsequently extracted. Prosthetic rehabilitation was performed with zirconia-based restorations: an implant-supported crown for the maxillary right central incisor and conventional crowns for the maxillary left central and lateral incisors.

Discussion: The use of a dental CAD/CAM workflow enabled precise fabrication of zirconia restorations, allowing the information from the provisional restoration to be accurately transferred to the definitive prosthesis. This approach ensured excellent fit and esthetics, contributing to stable postoperative function and favorable long-term prognosis.

Conclusion: Zirconia restorations, owing to their superior mechanical strength and esthetic qualities, proved to be a reliable option for both implant-supported and tooth-supported crowns, providing long-term stability and predictable prosthetic outcomes.
