角度基台生物力学影响的研究现状

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。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,发现角度基台的应用不会带来不良的临床影响,但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,如何合理利用角度基台带来有利的应力分布是以后口腔种植临床研究的一个方向。

The Biomechanical Influence of Angled Abutment in Dental Implants: A Review

The influence of angled abutments on stress of peri-implant bone is a controversial issue. It is widely accepted that the use of angled abutments will increase adverse stress distributions on implants and surrounding bones. However, comparisons of clinical success rates of implants restored with angled and straight abutments indicate no significant differences. This review summarized the clinical application and biomechanical research associated with angled abutments. The use of angled abutments did not detrimentally affect the retention of dental implants, and tt was possible that the magnitude of stress within peri-implant bone increased or decreased under different conditions. Therefore, further researches should be conducted to confirm that favorable peri-implant stress levels may be induced if suitable angulation of abutments is selected.
