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.
