膜引导骨再生技术在上前牙即刻种植中的应用

Clinical application of membrane guided bone regeneration in immediate implant of upper anterior teeth

目的探讨膜引导骨再生技术在前牙拔除后即刻植入种植体修复牙缺失的可行性。方法对25例（32颗）前牙拔除术后患者,即刻植入种植体于骨缺损区,填入人工骨粉并用修复膜封闭,4~6个月行冠修复,通过临床观察和放射学检查分析修复效果。结果 32颗种植体除1颗牙种植因感染失败外,其余种植体术后功能行使良好,冠修复后承载1年无松动。结论应用膜引导骨再生技术进行前牙即刻种植,解决了前牙拔除后唇侧骨缺损的不足,同时也缩短治疗疗程,获得满意效果。

Objective To investigate the feasibility of immediate implant fellowing extraction of anterior tooth with using membrane guided bone regeneration technique.Methods Thirty-two anterior teeth were pulled out from 25 patients in the surgery,and the immediate implants bone defect area was filled with artificial bone material.And then the barrier membrane was used to close it.After 4 to 6 months crown restoration were performed.The effects were evaluated through clinical observation and radiological examination.Results Among 32 implants there was only one tooth failed due to infection,the other function was well after implant surgery.After the crown restoration it was carried one year without any loose.Conclusion By the membrane guided bone regeneration technique the immediate implant of anterior teeth can be conducted which resolves the bone defect of lip side after the anterior teeth is pulled out.The result of immediately implant placement can reduce the treatment period so as to achieve satisfying effect.
