Objective: To evaluate the clinical effect of guided bone regeneration in maxilla anterior teeth esthetics implant-support prosthetic in distinguished type of bone defect. Method: 35 patients with alveolar deficiency underwent volume augmentation of the alveolar ridge with GBR techniques. 29 cases followed GBR procedures (resorbable collagen membrane were used for repairing and augmentation of the resorbed alveolar ridge around endosseous implants). 6 cases used autogenous block bone grafts harvesting from mandibular symphysis combined with GBR techniques. The implants were inserted at stage II after 5~6 months. Result: 6~12 months postoperatively guided bone regeneration guided new bone in the X-ray showed. All implants had ideal osseointegrated completely with new bone and alveolar bone which induced prosthesis undergo after implant placement 6~12 months later. After prosthesis restoration no one failed in 12 months follow-up time. Conclusion: GBR techniques all can successfully alveolar bone gain in anterior implants different type of bone defect, conforms to implant-support prosthetic to request.%目的：评估引导骨再生技术(GBR)在上前牙不同类型骨缺损种植修复中的效果。方法：对35例上前牙牙槽骨缺损种植的患者采用GBR技术进行骨增量，其中29例种植体周围骨缺损患者仅采用GBR技术，在植体植入骨床后，同期植入Bio～oss人工骨粉，表面盖Bio～gide可吸收性胶原膜；6例牙槽骨缺损患者采用移植自体块状骨联合Bio～oss人工骨粉，盖Bio～gide可吸收性胶原膜，5～6个月后行Ⅱ期种植体植入术。结果：所有患者在植体植入术后6～12个月临床观察种植体与骨结合良好，软组织形态与周围组织一致，行冠或桥修复，修复后12个月随诊复查无种植体失败。结论：引导骨再生技术皆能有效地对上前牙不同类型骨缺损进行骨增量，符合美学种植要求。
