摘　　要：当牙体缺损位于龈下,进行修复缺损时,如果出现修复体边缘不密合、粘接剂滞留等情况,会引发严重的牙周疾病。临床上可根据牙体缺损的深度选择不同的治疗技术来规避这些问题,以预防牙周疾病的发生,维持修复后患牙的牙周健康。临床常用的治疗技术包括排龈术、龈壁提升术、牙冠延长术、正畸牵引术。本文对龈下牙体缺损按照深度进行分类,综述了上述4种方法的适应证、特点、操作方法以及使用中避免牙周疾病发生的注意事项。When the tooth defect is under the gingiva,problems such as the edge of the restoration is not tight and the adhesive is retained cause serious periodontal diseases.Different clinical strategies can be employed to avoid these pro-blems according to the depth of the tooth defect to prevent periodontal diseases and maintain the periodontal health of restored teeth.Commonly used clinical treatment techniques include gingival retraction,deep margin elevation,crown lengthening,and orthodontic extrusion.In this paper,the indications,characteristics,operation methods,and means to avoid periodontal diseases in each method are described.
