拔牙后牙槽嵴保持的研究现状

摘要

Resorption of alveolar bone that occurs following tooth extraction is irreversible, it may compromise the restoration of implants or conventional prostheses.Ridge preservation can minimize ridge resorption after tooth extraction.In this article, healing features of socket after tooth extraction, factors influencing ridge remodeling, and the use of bioma-terials were reviewed.%拔牙后牙槽嵴会出现不可逆的骨吸收,常导致拔牙区骨量不足,可能会限制后期的种植或传统修复治疗,而牙槽嵴保持术可以减少拔牙后的骨量丢失.故本文从拔牙窝改建特点、影响拔牙窝的愈合因素及生物材料在牙槽嵴保持中的应用等几个方面作一综述.
