天然牙与种植体联合支持修复牙列缺损的研究进展

天然牙与种植体联合支持固定桥修复，为临床上有效修复牙列缺损提供了更多选择，但一直存在争议。有学者认为，天然牙与种植体联合支持固定桥在临床上是一种相对简便、经济、实用、有效的修复方式，天然牙与种植体联合支持固定桥修复远期效果良好，临床上可行。也有学者认为，种植体与天然牙联合修复未必是理想的选择，应尽量避免，当条件有限，无法行种植体支持固定桥修复时可选择应用。天然牙与种植体联合支持可摘局部义齿修复，种植体在缺牙远端的应用可以将可摘局部义齿形式由基牙-黏膜支持式转换为天然牙-种植体支持式，成功率较高。总之，当口内两单位以上牙列连续缺损时，种植体支持固定修复应为最佳选择；当受主客观条件所限难以实现时，可以行天然牙和种植体联合支持。

Research progress on restoration for dentition defects by combined support of implant and natural tooth

?Some controversies prevail on the clinical application of implant-natural tooth-supported fixed partial dentures. This technique could be a preferable choice for restoration of dentition defects because of its simplicity, effectiveness, and long-term results. However, the combination of tooth and implant has not been established as an ideal choice but may be a second choice when implant-supported bridge could not be used. Implant-natural tooth-supported removable partial dentures could also be considered. The application of implant in the distal region of dentition defects could switch the tooth-mucosa support to the tooth-implant support with a high success rate. In conclusion, implant-supported fixed partial dentures may be an optimal choice in the condition of continuous dentition defects; otherwise, the combined support of implant and tooth could be used..
