目的：探讨因牙周炎无法保留的患牙在拔牙的同时植入血浆提取物‐浓缩生长因子（CGF）复合骨诱导活性材料，行拔牙位点保存技术，观察其对预防牙槽骨吸收的临床效果。方法：纳入因牙周炎不能保留患牙32颗，微创拔除后同期植入患者自体 CGF 复合 Bio‐OSS 骨粉，并覆盖CGF 膜，严密缝合，术后6月通过拍摄 X 线及锥体束 CT （CBCT ），了解牙槽骨量变化。结果：拔牙创愈合良好，术后6个月，牙龈形态饱满，牙槽骨高度及宽度保存良好。结论：位点保存技术中使用CGF 复合骨诱导活性材料可以很好地维持牙周炎患牙拔除后牙槽骨骨量，为后期的种植修复提供良好的牙槽骨条件。%Objective :To observe the clinical effects on prevention of alveolar bone absorption by site preservation after tooth extraction due to serious chronic periodontitis .Methods :The fresh sockets were immediately grafted and filled with CGF compounded with Bio‐Oss and CGF membrane after minimally invasive tooth extraction , the clinical effect was observated change by taking X‐ray and CBCT after 6 months .Results :No infection case was found in all patients ,After six months ,alveolar bone height and width in good condition ,gingival was plump .Conclu‐sion :CGF compounded with osteoinduction active material technique can have good effect on guiding bone regenera ‐tion ,and can meet the needs of post‐implanting .
