微创种植固定修复在下颌无牙颌患者中的临床应用研究

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。

The clinical application study of dental implant fixed prosthesis obtained with minimally invasive surgery in edentulous patients of mandible

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.
