Prosthetic complications in All-on-X restorations are related to the material of the framework. Polyether ether ketone (PEEK) is an innovative alternative, but its clinical performance has not yet been established. Therefore, the aims of this study was to analyze the clinical survival and prosthetic complications associated with the use of PEEK frameworks in All-on-X implant-supported prostheses through a systematic review. The systematic review was conducted in four phases and included scientific publications on this topic that met the established inclusion and exclusion criteria. The results demonstrated that there are few clinical studies on prosthetic or implant follow-up, of which in vitro or Finite Element Analysis (FEA) studies are the most common. Likewise, most clinical studies showed implant survival rates between 98% and 100%, while prosthetic survival ranged from 93% to 100%. On the other hand, the most common complications were loosening of prosthetic screws, prosthetic fractures, and adhesion failures. In conclusion, it was determined that although PEEK represents a potential alternative for frameworks in implant-supported full-arch restorations, the available evidence is dominated by experimental studies and presents consistent results. More longitudinal clinical studies are needed to establish its actual performance under functional conditions.
