Abstract: Edentulism is a common yet complex condition in clinical dentistry that significantly compromises masticatory function，speech，and overall quality of life of patients. Full-arch implant-supported fixed rehabilitation，which offers masticatory efficiency closely approximating that of the natural dentition，along with favorable esthetic outcomes and long-term stability，has become a principal treatment modality for edentulous patients. Nevertheless，clinical consensus remains lacking regarding several critical aspects of full-arch implant-supported fixed rehabilitation，including the determination of vertical dimension，the number and distribution of implants，occlusal design，management of provisional restorations，clinician-technician collaboration，and peri-implant maintenance. From a multidisciplinary perspective encompassing prosthodontics，implantology，dental esthetics，prosthodontic technology，and periodontology，this consensus integrates clinical experience and current evidence to provide guidance on these critical aspects，with the aim of informing clinical practice in implant-supported fixed rehabilitation for edentulous jaws.

摘要： 牙列缺失是口腔临床常见的复杂问题，严重影响患者的咀嚼、发音及生活质量。无牙颌种植固定修复具备接近天然牙列的咀嚼效率、良好的美学效果和稳定性，已成为牙列缺失的重要修复方式。然而，目前无牙颌种植固定修复在垂直距离、种植体数目与分布、咬合设计，以及临时修复、医技协作、种植体周维护等关键环节尚缺乏共识。该共识从口腔修复学、口腔种植学、口腔美学、口腔修复工艺学及牙周病学等多学科视角出发，结合临床经验与现有研究证据，对以上关键环节提出指导意见，以期为无牙颌种植固定修复的临床实践提供参考。
