摘　　要：目的探讨上颌中切牙缺失且无明显垂直骨高度缺失患者的美学种植手术的方案设计与术后临床效果研究。方法 25例上颌中切牙缺失的患者,植入ITI种植体34颗,骨量不足者,在缺损区植入Bio-Oss人工骨粉,覆盖Bio-Gide可吸收生物膜,植入后3～6个月完成上部结构修复,术后随访6～12个月。结果 25例患者共34颗种植体稳固无松动,患者无明显不适感,短期种植成功率100%。随访期间,1例患者唇侧牙龈退缩。临床效果满意率达96%。结论上颌中切牙缺失且牙槽嵴厚度不足时,可根据牙槽嵴宽度的情况,选择不同的手术术式,同时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 the clinical effects and operation designs of aesthetic implantation surgery in cases of maxillary cen- tral incisor lost with insufficient vertical alveolar bone height. Methods 25 patients with maxillary central incisors loss were placed with 34 ITI implants. The cases of insufficient bone were implanted with Bio-Oss artificial bone and covered with Bio-Gide absorbable biological film in maxillary edentulous ridges. Superior restorations were completed 3-6 months subsequently. All cases were followed up for 6-12 months. Results All the 34 implants in 25 patients were all firm, without obvious discomfort. Short-term implantation success rate was 100%. In the follow-up, gingival loss occurred to 1 patient. Patients＇ satisfaction rate of clinical effects was 96%. Conclusions In case of maxillary central incisor loss with insufficient alveolar bone height, different surgical methods should be chosen according to the widths of alveolar ridges. Also the GBR technique should be adopted to rebuild adequate alveolar bone. Make sure of the implanta- tion success rate,and satisfy patients＇ aesthetic requirements.
