摘要
目的：探讨应用骨胶原及富血小板纤维蛋白保存牙槽嵴的技术要点,评估其临床效果.方法：选择2006- 07~2010- 01间36 例（42 颗患牙）上前牙拔牙同期应用骨胶原及富血小板纤维蛋白保存牙槽嵴的病例,延期种植、修复,进行临床和放射学评估,随访时间平均14.6 个月（3~48 个月）.结果：42 个牙位中的5 个牙位早期种植,37 个牙位延期种植;42 个牙位中的21 个牙位简单种植,7 个牙位种植手术结合软组织移植,14 个牙位种植手术结合GBR植骨.平均牙间乳头指数2.8,平均边缘骨吸收0.27 mm,种植体成功率100%.结论：应用骨胶原及富血小板纤维蛋白保存牙槽嵴短期临床效果满意.
Objective： To evaluate the effects of Bio-Oss Collagen and platelet-rich fibrin （PRF） in maxillary anterior region for ridge preservation. Methods： From July 2006 to January 2010, 42 teeth in maxillary anterior region of 36 patients were extracted and treated with Bio-Oss Collagen and PRF immediately. Implantation and restoration were completed subsequently. Data of clinical and radiographic examinations were collected during the follow-up period ranged from 3 to 48 months. Results： Early implant placement was applied in 5 of the 42 sites, and delayed implant placement in the other 37 sites. Implants were directly placed in 21 of 42 sites, implants with connective tissue grafts were placed in 7 sites, implants with GBR were placed in 14 sites. The gingival papilla index was 2.8 on average, the marginal bone resorption was 0.27mm on average, and implantation success rate was 100%. Conclusion： Bio-Oss Collagen combined with platelet-rich fibrin is effective in the ridge preservation in maxillary anterior region in short term fol- low- up.
