摘要
目的探讨上颌中切牙缺失后无明显垂直骨高度缺失的患者,在种植同期行GBR术后短期内骨量的变化研究。方法23例上颌中切牙缺失的患者,完成Osstem种植体31颗植入,在缺损区植入Bio-Oss人工骨粉,覆盖Bio-Gide可吸收生物膜,植入6-9个月,行牙龈诱导后完成上部结构修复,术后随访6-12个月。结果 23例患者共29颗种植体稳固无松动,患者无明显不适感,短期种植成功率93.5%;美学效果恢复良好。结论上颌中切牙缺失且牙槽嵴唇腭侧宽度不足时,可采用引导骨再生技术来恢复牙槽嵴的丰满度,保证种植成功率,满足患者的美学要求。
Objective To study Bone quantity changes in cases of maxillary central incisor lost with insufficient horizontal alveolar bone width. Methods 23 patients with maxillary central incisors loss were placed with 31 Osstem implants. The cases of insufficient bone were implanted with Bio-Oss artificial bone and covered with Bio-Gide absorbable biological film in maxillary e-dentulous ridges. Superior restorations were completed 6-12 months subsequently. All cases were followed up for 6-12 months. Results All the 29 implants in 23 patients were all firm,without obvious discomfort. Short-term implantation success rate was 93. 5%. Conclusion In case of maxillary central incisor loss with insufficient horizontal bone width ,the GBR technique should be adopted to rebuild adequate alveolar bone. Make sure of the implantation success rate,and satisfy patients' aesthetic requirements.
