CGF联合Bio-oss骨粉在拔牙窝保存术中的应用

CGF combined with Bio-oss in the preservation of tooth extraction socket

目的:评价CGF联合Bio-oss骨粉在拔牙窝保存术中的作用。方法:收集20位下颌磨牙拔牙患者作为拔牙窝保存术病例,采用锥形束计算机断层扫描(CBCT)技术,测量拔牙前及拔牙后植入CGF联合Bio-oss骨粉6个月后牙槽骨的高度、宽度和密度。结果:拔牙前和拔牙后6个月比较,牙槽骨高度差异无统计学意义(Z=-1.475,P>0.05),宽度差异具有统计学意义(Z=-3.716,P<0.05),密度差异无统计学意义(Z=-1.195,P=0.23);拔牙后植入CGF联合Bio-oss骨粉6个月后牙槽骨高度和宽度吸收率比文献统计吸收率平均值低。结论:CGF联合Bio-oss骨粉在拔牙窝保存术中能有效维持牙槽骨的高度和宽度,同时较快促进牙槽骨的生成。

Objective： To evaluate the role of CGF combined with Bio-oss in the preservation of tooth extraction socket. Methods： A total of 20 mandibular molar extraction patients were collected as the case of the tooth extraction socket in this study. The cone-beam computed tomography（CBCT） technique was used to measure the bone height, width, and density from CGF combined with Bio-oss 6 months before and after extraction. Results： There was no statistical significant difference in alveolar bone height between pre-extraction and post-extraction（p〉0.05）. The width had significant difference（p〈0.05）. There was no statistical difference in density（p〉0.05）. After 6 months of implantation of CGF combined with Bio-oss bone meal, alveolar bone height and width absorption rate was lower than the average of the literature. Conclusion： CGF combined with Bio-oss bone powder can effectively maintain the height and width of alveolar bone in the extraction site of tooth extraction, and accelerate the generation of alveolar bone more quickly.
