    摘要:

    角度基台对种植体周围骨组织应力分布的影响是一个有争议的问题,目前比较一致接受的观点是在种植修复中使用角度基台会增加种植周围骨组织不利的应力分布。但是临床观察确没有发现角度基台对种植修复带来不良的影响。本文通过总结角度基台的临床应用及其影响、角度基台相关生物力学研究的文献。在临床观察结果显示角度基台的应用不会带来不良的临床影响,基台角度变化确实会给种植体周围组织应力分布带来一些变化,增大和减小种植体周围组织应力分布都是可能的。因此怎样合理利用角度基台带来有利的应力分布是以后研究的一个方向。

    Abstract:

    The influence of angled abutments on stress is a matter of debate. It is widely accepted that increased stress on implants and bone has been associated with the use of angled abutments. However, comparisons of clinical success rates of implants restored with angled and straight abutments indicate no significant differences. This review summarizes the dental literature for for clinical trials that appraised the survival rate and biomechanical complications associated with prostheses that are supported by angled abutments. The results demonstated that the use of angled abutments did not detrimentally affect the retention of dental implants. it was possible that the magnitude of stress within peri-implant bone increased or decreased under different conditions. Further research should be conducted to confirm that favorable peri-implant stress levels may be induced if suitable angulation of abutments was selected.
