摘要：

目的：分析基于Bio-Oss Geistlich的拔牙位点保存技术对于患者牙槽骨吸收及短期美学疗效的影响。方法：选择2013年5月～2016年5月我院牙科种植中心收治的100例患者作为研究对象，随机分为实验组和对照组，实验组患者在拔牙窝内植入Bio-Oss Geistlich，表面覆盖Heal-RLL膜。对照组患者采用压迫止血或缝合。对比两组患者的拔牙位点愈合情况，牙槽骨变化及吸收情况和短期美学效果。 结果：实验组患者拔牙位点处轮廓丰满，对照组患者拔牙位点处轮廓萎缩，吸收明显；实验组患者前牙区和后牙区的骨密度均高于对照组，差异具有显著性（P<0.01）；实验组患者前牙区和后牙区的骨高度吸收值、骨宽度吸收值均明显小于对照组，差异具有显著性（P<0.01）；实验组患者对前牙美学区的美观效果满意率明显高于对照组，差异具有显著性（P<0.01）。 结论：基于Bio-Oss Geistlich的拔牙位点保存技术能够有效保护拔牙位点，防止牙槽骨吸收、牙龈萎缩，同时具有较好的短期美学疗效，值得推广应用。

Objective: To analyze the effects of extraction site preservation based on Bio-Oss Collagen on the alveolar bone resorption and short-term anesthetic effectiveness. Methods: 100 cases of patients admitted by dental planting center from 2012 to 2015 were randomly divided into the experimental group and the control group. Patients in the experimental group were implanted with Bio-Oss Collagen in alveolar fossa after extraction covered with Bio-Gide. Patients in control group were treated with oppression hemostasis or suture. The healing situation of extraction site, the alveolar bone resorption and the short-term anesthetic effect were compared between two groups. Results: The sit contour in the experimental group is full, while that in the control group is shrinking and alveolar bone resorption can be seen; the mineral density in anterior areas and posterior areas in the experimental group is significantly higher than the control group (P<0.01); the high absorption, the width absorption mean value in anterior areas and posterior areas in the experimental group is significantly lower than the control group (P<0.01). Conclusion: Extraction site preservation based on Bio-Oss Collagen can reduce the alveolar bone resorption, has good protective effect on the extraction site, can keep great anesthetic effect which makes it worthy popularizing in clinical treatment.
