位点保存术在口腔种植中的研究进展

Research progress of socket preservation technique in oral implantology

良好的牙槽骨形态和充足的骨量对种植成功具有重要意义,部分患者因拔牙前已存在中重度的牙槽骨缺损,在牙槽窝愈合后牙槽骨不能达到理想的高度及宽度,使种植难度增加。位点保存作为临床常用的骨量保存方法,可有效减少牙槽骨吸收,维持软组织轮廓,本文就位点保存术在口腔种植中的研究进展作一综述。

The good alveolar bone shape and sufficient bone mass are of great significance to the success of implantation.Some pa-tients have moderate to severe alveolar bone defect before tooth extraction;thus the alveolar bone could not reach the ideal height and width after socket healing,which increases the difficulty of implantation.Socket preservation,as a common clinical method,can reduce alveolar bone absorption and maintain soft tissue contour.This article will review the research progress of socket preservation in oral im-plantation.
