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。

[Abstract]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.

口腔种植体具有独立牙根、不磨改邻牙、支持力强和义齿咀嚼效率高等优点,近年来其应用范围不断拓展。对于两单位以上的牙列缺损,种植体独立支持的联冠或固定桥可满足临床需要[1],但在牙槽骨骨量不足,患者拒绝骨增量手术,天然牙松动需行夹板固定以及经济原因等情况下,可考虑先植入适量种植体,然后行天然牙与种植体联合支持修复[2]。……
