摘　　要：目的:研究Bio-Oss骨粉+胶原膜(海奥)和骨胶原在位点保存中的临床效果。方法:选取患牙26颗,随机分为2组。骨粉组13例,于拔牙窝内植入Bio-Oss骨粉,表面覆盖胶原膜(海奥);骨胶原组13例,于拔牙窝内仅植入BioOss骨胶原。3个月后复查,观察2组患牙牙槽窝愈合情况,于位点保存术后即刻和术后3个月进行锥形束CT(CBCT)检查,测量牙槽骨垂直向高度与水平颊舌向厚度、CBCT灰度值的变化,临床观察新骨外形轮廓的改变,评价位点保存的临床效果。采用SPSS 17.0软件包对数据进行处理。结果:2组在新骨外形轮廓方面无显著差异(P>0.05);术后3个月,2组牙槽骨高度、厚度均减低,灰度值升高,均有统计学差异(P均<0.01),但2组疗效无显著差异(P均>0.05)。结论:2种材料用于位点保存时效果无显著差异,但使用骨胶原的位点保存技术操作简单,创伤小,费用低。PURPOSE:To investigate the effect of Bio-Oss bone powder combined with Heal-All Oral repair membrane and Bio-Oss collagen on site preservation during implantology.METHODS:A total of 26 cases were randomly divided into 2 groups.In Bio-Oss bone powder group(13 cases),the sockets were filled with Bio-Oss bone powder,covering with Heal-All Oral repair membrane on the surface.In Bio-Oss collagen group(13 cases),the sockets were filled with Bio-Oss collagen only.The changes in alveolar bone density,height,width and new bone contour were evaluated with cone-beam CT(CBCT)after site preservation.The data were analyzed with SPSS 17.0 software package.RESULTS:There was no significant difference in new bone contour between 2 groups(P>0.05).The changes in height,width and grey level of alveolar bone between the two groups were significantly different after 3 months of follow-up(P<0.01),but the curative effect was similar(P>0.05).CONCLUSIONS:There is no significant difference in the efficacy of site preservation between the two materials.However,the site preservation technique using collagen is simple,less invasive and less costly.
