PRISMA-P checklist for Clinical Outcomes of Polyetheretherketone (PEEK) Hybrid Prosthesis in All-on-Four Rehabilitation: A Systematic Review Protocol

The "all-on-four" concept is a significant advancement in dental implantology, particularly in cases of extensive jaw bone loss. However, implementing this technique successfully requires careful planning regarding implant selection, materials, and prosthesis design. The recent introduction of PEEK (Polyetheretherketone) in dentistry prompts questions about its efficacy compared to conventional materials like titanium and zirconia. This systematic review protocol aims to gather evidence on PEEK's effectiveness in the all-on-four approach.
