Summary
This study compares long-term peri-implant outcomes between two mandibular full-arch rehabilitation approaches-four-implant-retained overdentures and All-on-4 fixed prostheses-when both are fabricated with polyetheretherketone (PEEK) frameworks. While overdentures and All-on-4 prostheses are widely used, evidence on the clinical performance of PEEK frameworks in these modalities is scarce. By evaluating marginal bone loss and other peri-implant parameters, the research aims to clarify whether prosthetic design influences biological outcomes when using this high-performance polymer.
