The effect of orbital implant load angle on the stress distributions of peri-implant surface / 实用口腔医学杂志

Objective:To observe the effect of orbital implant load angle on the stress distribution of peri-implant surface.Methods:The 3D finite element analysis model of orbital implant with diameter of 3.75 mm and length of 6 mm was established.A force of 20 N was applied on the model at various angles.The stress distribution and displacement of the implant were recorded and analyzed.Results:Under 0°,1 0°,20°,30°,45°and 90°the maximum stress(MPa)on the peri-implant surface was 3.1 73,6.535,1 0.506,1 4.1 68, 1 8.949 and 24.755,the maximum displacement(μm)of the implant was 1 .761 ,3.654,7.665,1 1 .567,1 6.774 and 25.072,respec-tively.Conclusion:The loading angle is an important factor influencing stress and displacement of peri-implant bone.
