Abstract

An implant-supported hybrid prosthesis is a fixed restoration composed of a metal framework and acrylic resin, offering advantages such as aesthetics, function, phonetics, and lip support, while providing retention and support through the splinting of implants with the metal framework. However, poor oral hygiene can lead to peri-implantitis, and long-term use may result in wear or fracture of the artificial teeth, causing reduced masticatory function and loss of vertical dimension. Traditionally, a new metal framework is cast for remanufacturing, but if the existing framework is intact, it can be reused for a more rapid and simplified protocol. This case involves a 58-year-old male patient with peri-implantitis, where some implants were removed and treated, and the superstructure was remanufactured using the existing metal framework. By preserving the existing metal framework during the remanufacturing of the implant-supported hybrid prosthesis, the treatment time and number of visits were reduced, minimizing patient discomfort.
