Abstract
This clinical report describes a case involving a 74-year-old woman with maxillary edentulism who was successf ully treated using an implant-supported hybrid prosthesis. The f ramework of the prosthesis was fabricated using polyetherketoneketone (PEKK), which is a high-performance polymer, and individual lithium disilicate ceramic crowns were cemented for optimal esthetics. No mechanical or biological complications were observed during a 3-year follow-up period. Further clinical studies and long-term clinical data regarding the usef ulness of PEKK as a f ramework material for dental prostheses are necessary.
