Zygomatic Implant-Supported Prosthesis: When the Prosthetic Rehabilitation Affects the Function: A Case Report

Abstract

The oral rehabilitation of edentulous patients can be done in different ways depending on the alveolar ridge morphology and patient expectations. The objective of this clinical case was to report prosthetic and functional adapta-tion difficulties when conventional complete denture was changed to a zygo-matic implant-supported prosthesis. We report a 52-year-old male singer with an atrophic maxilla who was rehabilitated with zygomatic implant-supported prosthesis using 4 implants. However, the thickness of the prosthesis in the palatal region and the space between the prosthesis and soft tissue caused dif-ficulty in speaking and singing. The palatal region of the prosthesis was trimmed and the anterior region of the prosthesis was relined. These proce-dures were performed to make room for the tongue and minimize the passage of air during speech. Adaptations in the shape of the prosthesis must be made to enable its use, without compromising its strength.
