Abstract

Purpose: To develop, analyze, and optimize a dental implant by considering square threads and varying the thread dimensions to obtain an optimal shape. Materials and Methods: For this study, finite element analysis (FEA) and numerical optimization method were integrated to develop a mathematical model. The critical parameters of dental implants were studied, and an optimized shape was obtained using response surface method (RSM) and design of experiment (DOE). The simulated results were then compared to the predicted values under optimal conditions. Results: Using the one-factor RSM design model for the dental implant and a vertical compressive load of 450 N for testing, the optimal depth to width ratio for the thread was 0.7 in order to achieve the minimum von Mises and shear stress. Conclusion: The buttress thread was found to be the optimal shape for achieving the lowest von Mises and shear stress compared to square threads, and the thread parameters were calculated accordingly, with a thread depth 0.45 times the pitch, a width 0.3 times the pitch, and a thread angle of 17 degrees. Also, due to the constant diameter of the implant, common 4-mm diameter abutments can be used interchangeably.

基于有限元分析和实验设计的牙种植体模型优化。
目的:通过考虑方螺纹和改变螺纹尺寸以获得最佳形状来开发,分析和优化牙科种植体。材料与方法:本研究采用有限元分析(FEA)和数值优化方法相结合的方法建立数学模型。采用响应面法(RSM)和实验设计法(DOE)对种植体的关键参数进行了研究,得到了种植体的最佳形状。然后将模拟结果与最优条件下的预测值进行比较。结果:采用单因素RSM设计模型,在450n的垂直压缩载荷下进行测试,获得von Mises和剪切应力最小的最佳螺纹深宽比为0.7。结论:与方螺纹相比,支撑螺纹是获得最小von Mises和剪切应力的最佳螺纹形状,并据此计算螺纹参数,螺纹深度为0.45倍节距,宽度为0.3倍节距,螺纹角为17度。此外,由于种植体的直径恒定,常见的4毫米直径的基台可以互换使用。
