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.

6 年随访牙周炎患者种植体支持的全牙弓固定义齿的聚醚醚酮框架：病例报告。

种植牙广泛用于牙周炎引起的缺牙颌患者的康复。种植体的成功与否与其骨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，作为全口义齿的框架具有广阔的前景，但缺乏长期的随访数据。本临床报告展示了使用 PEEK 框架为被诊断患有牙周炎的患者构建种植体支持的全牙弓固定义齿。在生物宽度的指导下，实现了临时保留修复体以创建出现轮廓，从而产生具有良好美学和生物功能的 3D 打印 PEEK 框架。
