摘　　要：牙齿大面积缺损,尤其是延伸至釉牙骨质界(CEJ)下的缺损,是一种非常常见的临床情况。龈壁提升术是目前针对累及CEJ下缺损提出的一种微创修复技术,然而龈壁提升后牙齿、提升材料和瓷修复体之间粘接界面的微渗漏,修复体和牙体的抗折裂性能以及牙龈组织健康情况受龈壁提升的材料选择、提升高度、提升边缘设计的影响。目前,尚无统一、规范的设计原则和临床操作流程可供参考。本文对龈壁提升术材料选择、提升高度、龈壁边缘形态设计以及应力分布的相关研究进展作一综述。Large posterior defects,especially those extending below the cemento-enamel junction,are common.Deep margin elevation(DME)has become a less invasive technique for restoring these defects.However,critical factors,such as the type,height,and form of the base materials,could affect the marginal quality,fracture resistance of restorations,and the periodontal health.At present,a unified and standardized design principle and clinical operation procedure of DME for reference are lacking.This review summarizes the research progress on material selection,lifting height,and gingival wall edge shape design and stress distribution in DME.
