【摘要】 目的:观察因根端囊肿合并感染致牙槽骨缺损后拔牙同期植入Bio-Oss Collagen加用GBR技术,对牙周软硬组织的保存效果。方法:因有根端囊肿合并感染而拔牙的28例患者随机分为两组,实验组拔牙后牙槽窝中植入Bio-Oss Collagen胶原骨,其上覆盖Bio-gide膜行位点保存,对照组拔牙后不做处理。结果:术后观察28例患者创口均为一期愈合,实验组软硬组织位点保存良好,为延期种植修复提供了足够的骨量。结论:牙槽骨缺损后拔牙同期行位点保存可提供足够的牙槽骨高度与宽度及周围软组织的量,使之外形丰满,为延期种植打下美学修复成功的基础,提高患者满意度。更多还原

【Abstract】 Objective:To observe the effect of post-extraction alveolar preservation on periapical cyst-affected tooth with the aid of Bio- Oss Collagen and GBR technique.Methods:28patients were randomly devided into experimental group and control group.After extraction of periapical cyst-affected tooth,the experimental group received Bio-Oss Collagen treatment and GBR while control group received no post-extraction treatment.Results:Postoperative observation of both groups indicated a better bone regeneration and less alveolar ridge height loss in the experimental group.Conclusion:Post-extraction alveolar preservation might be recommended for alveolar ridge regeneration after periapical cyst-affected tooth were extracted.更多还原
