文题释义:
牙根盾技术:是牙科种植学科中一项新兴的自体组织保存技术,通过保留种植位点无症状的天然牙根组织,利用局部的自体Sharpey纤维,它是骨内的一种胶原纤维,将骨外膜内的胶原纤维穿入骨组织,使骨外膜连接到骨上,完成束状骨复合体维持植体周围牙槽骨、龈组织形态。
种植体周围组织保存:牙科种植体周围充足稳定的牙槽骨是支撑软组织形态、维持美学效果的关键因素,牙体缺失后,菲薄的牙槽窝骨壁将经历严峻的改建萎缩,目前临床多用骨移植、引导组织再生、骨劈开等超量组织补偿的方式来弥补缺牙区的骨萎缩量,称为种植体周围组织保存。
 
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PubMed、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。

Abstract:

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.
