种植体天然牙联合支持固定桥修复短期临床评价

目的：评价种植体天然牙联合支持固定桥修复的短期临床疗效。方法：2008年1月～2013年1月接受种植体天然牙联合固定桥修复35例，种植体桥基牙38颗。随访6～66个月，拍摄X线片测量种植体周围骨吸收量，进行临床疗效评价，应用寿命表法计算种植体5年累积存留率。结果：种植体年均骨吸收量为（0．22＆#177;0．12）mm，种植体天然牙联合支持固定桥修复5年有效率为94．3％，种植体5年累积存留率94．5％。结论：种植体天然牙联合固定桥是一种可行的修复方式，可以取得较好的临床修复效果，长期效果有待于进一步观察。

A short-term clinical assessment of implant-tooth supported fixed partial denture (FPD)

Objective：To evaluate the clinical effect of implant-tooth supported fixed partial denture. Method： From January 2008 to January 2013,35 patients with implant-tooth supported fixed partial denture were followed up for 6~66 months.Peri-implant bone absorption was measured by X-ray and clinical evaluation was performed,then cumulative sur-vival rate was calculated by life-table analysis. Result：There was （0.22±0.12）mm in annual crestal bone loss and the effi-ciency of implant-tooth supported fixed partial denture over 5 years was 94.3 %,the implant cumulative survival rate was 94.5%. Conclusion：Implant-tooth supported fixed partial denture which may be successfully used in dentition defect is vi-able,whereas the long-term effects need further research.
