摘　　要：背景:牙缺失导致的牙槽骨吸收是一个长期持续的过程,前牙区牙缺失后唇侧组织退缩更为显著,需要联合组织保存技术来降低美学风险。牙根盾技术是新近提出的自体组织保存技术。目的:就牙根盾技术的组织保存原理、结合界面基础及应用类型做一综述。方法:以"Socket shield technique;root-membrane technique;root-implant;implant proximity to teeth;dental-contected implants;Dentointegration;cementum formation on implant surface"为检索词,由第一作者对1990年1月至2017年10月间Pub Med、Ovid、中国知网数据库、维普数据库和万方数据库的文献进行计算机检索。结果与结论:牙根盾技术通过保留局部自体牙根-牙周韧带-束状骨复合体,维持相应牙槽骨、龈组织形态,可作为美学区种植体周围组织保存的一种方式。BACKGROUND:Absorption of the alveolar bone subsequent to tooth extraction is a long-term process,especially in the anterior tooth region where the buccal part of the ridge undergoes a prominent remodeling process after tooth extraction.Socket shield technique(SST)recently reported may be a new choice for peri-implant tissue preservation.OBJECTIVE:To give an overview on the principle,interface basis and application of SST in implant dentistry.METHODS:The first author searched the PubMed,Ovid,CNKI,VIP and WanFang databases for relevant articles published from January 1990 to October 2017.The keywords were“socket shield technique;root-membrane technique;root-implant;implant proximity to teeth;dental-contected implants;dentointegration;cementum formation on implant surface”in Chinese and English,respectively.RESULTS AND CONCLUSION:SST aims to maintain alveolar bone and gingival tissues by preserving partial tooth root with its periodontium-bundle bone intact,which is an alternative strategy for tissue preservation in esthetics zone.
