Dental implants are widely used in the rehabilitation of patients with edentulous jaws caused by periodontitis. The success of implants is closely related to their framework material and patients’ periodontal health. Polyetheretherketone (PEEK) is a kind of high polymer material that has broad prospects as the framework for full-arch dental prostheses, but long-term follow-up data are lacking. The present clinical report demonstrates the use of a PEEK framework for the construction of an implant-supported full-arch fixed dental prosthesis for a patient diagnosed with periodontitis. With the guidance of biological width, a provisional retained restoration was achieved to create the emergence profile, resulting in a 3D printed PEEK framework with good aesthetics and biological functions.
