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.
牙种植体广泛应用于牙周炎导致的无牙颌患者的修复。种植体的成功与其框架材料和患者的牙周健康密切相关。聚醚醚酮（PEEK）是一种高分子材料，作为全牙弓义齿的框架具有广阔的前景，但缺乏长期随访数据。本临床报告展示了使用PEEK框架为一名诊断为牙周炎的患者构建种植体支持的全牙弓固定义齿。在生物学宽度的指导下，实现了临时保留修复以形成龈缘外形，从而得到具有良好美学和生物学功能的3D打印PEEK框架。
