目的：通过在下颌微创种植8枚种植体，使下颌无牙颌患者获得固定义齿。方法：对下颌无牙颌要求种植固定义齿的患者进行筛选，制定详细的治疗方案。采用不翻瓣的手术方法植入8枚种植体，对患者原义齿缓冲后做过渡使用。术后6个月采用黏固式分段烤瓷桥的设计方式修复完成至少12牙单位修复。结果：本院自2006年至2013年期间采用此方法对下颌无牙颌患者完成种植固定义齿修复18例，追踪期（0.8~7年）内，种植体存留率100%，种植体周围组织稳定，义齿局部崩瓷一例。结论：下颌无牙颌患者8枚种植体支持的固定义齿咀嚼功能恢复理想，患者使用舒适方便，义齿卫生易于维护，患者接受度和满意度高。

Objective: The purpose of this clinical study was edentulous patients of mandible for fixes pros-thesis were implanted 8 implants by way of minimally invasive surgery. Methods: The edentulous pa-tients of mandible that required dental implant fixed prosthesis were selected. The detailed treatment plans were made. 8 implants were implanted by way of flapless surgery method. The old denture was used, after it was modified. About 6 months later, PFM bridges of implants were made and at least 12 teeth were restored. Results:Dental implant fixed prosthesis of 18 edentulous patients of mandible were finished using this method from 2006 to 2013. During the follow-up visit period (0.8 to 7 years), the survival rate of implants was 100% and the tissue around implants was stable. the local porcelain cracking was happened in 1 PFM bridge. Conclusion: 8 implants supported fixed denture could make the edentulous patients of mandible obtained ideal the masticatory function. The denture was comfort-able and convenient. Denture hygiene is easy to maintain. The acceptance and satisfaction of patients were high.
