A case report of oral rehabilitation using an implant-supported prosthesis for unilateral posterior edentulous maxilla

Abstract

Patient: A 62-year-old female visited our department complaining of pain in the upper left tooth. The upper left first premolar was extracted due to a root fracture. Implants were placed in the upper left posterior region, avoiding the first premolar site, because the root of the upper left canine was significantly distally inclined. Subsequently, an implant-supported hybrid composite resin-facing fixed partial denture with a mesial cantilever, made of a gold alloy, was installed.

Discussion: Since excessive occlusal forces and parafunction were suspected due to a history of root fracture, the occlusal surface of the final prosthesis was made of metal to prevent wear and chipping, which resulted in a stable long-term outcome.

Conclusion: The implant prosthesis for a patient with Kennedy class II partially edentulous resulted in good outcomes with high patient satisfaction by establishing occlusal support and selecting materials that can withstand occlusal force, along with concurrent training for oral function to help improve and maintain mastication.
