利用全口覆盖式种植义齿对牙列缺失患者进行修复治疗有利于获得义齿良好的稳定和固位并日益取得了同全口固定式种植义齿相近的修复效果。全口覆盖式种植义齿根据其固位形式的不同可分为杆卡附着式种植义齿、球帽附着式种植义齿、磁性附着式种植义齿,不同的设计方式对临床应用将带来不同的影响。本文综述了覆盖式种植义齿相关的生物力学、种植体数目、即刻加载、临床性能以及维持和并发症等。 Rehabilitation treatment of patients with dentition defect with full-mouth implant denture is beneficial to obtain good stability and retention of the denture, and has increasingly achieved the same restoration effect as the full mouth denture. All-mouth implant dentures can be divided into rod-attached implant denture, ball-cap implant denture and magnetic attachment implant denture according to their different retention forms. Different design methods will have different effects on clinical application. This article reviews the biomechanics, implants, immediate loading, clinical performance, maintenance and complications of overlay dentures.
