摘要 为了探讨受力角度对螺旋型种植牙周骨界面应力分布规律的影响，本实验采用三维有限元方法，在相同载荷不同受力角度时，对单个螺旋型种植牙骨界面的应力分布特点进行了比较分析。结果表明：种植牙受力角度的增加，主要对种植牙颈周密质骨影响明显，受力角度越大，应力就越大。颈部应力与种植牙受力角度成正比。颈部位移运动随种植牙受力角度的增加而增加。侧向载荷时，以水平向危害最大。 In order to investigate The influence of loading angles of screw dental implant on the stress distribution patterns at the bone interface around dentaI implants, authors analyzed loading angles of screw dental implant on the stress distribution patterns at the bone interface around dental implants in the same load using three-dimension finite element method. The results showedt Increasing the loading angle of screw dental implants mainly affected the stress magnitudes at the neck bone around the implants and the motions of displacements, the more load angles, the more stress magnitudes and motions of disp1acements. When the lateral loads the most danger was the horizontal loads.
