摘　　要：目的:研究加载方向对Spline种植体-基桩界面应力分布的影响。方法:利用3D-FEA方法分析比较Spline种植体-基桩界面各部件在施加四种不同方向100N载荷后的应力分布情况。结果:随着加载角度的增加,种植体、基桩及中央螺钉上的应力值均增加,不同方向载荷下种植体上的最大应力值均位于Spline突起的根部。结论:斜向载荷对Spline种植体-基桩连接界面的应力影响较大。Objective：To examine the effects of load direction on stress distribution of Spline implant-abutment joint.Methods：3D-FEA is used to determine stress distribution of the implant, abutment and screw under four different direction load with a value of 100N. Result：The stress of Spline connection developed with the increase angle of the applied load .Maximum Von Mises stress of the implant locates at the root of the Spline projections.Conclusion：The stress distribution of Spline implant-abutment interface was significantly affected under lateral loading.
