摘　　要：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.Conclusion：CGF compounded with osteoinduction active material technique can have good effect on guiding bone regeneration,and can meet the needs of post-implanting.
