本文主要目的是介绍均匀设计在动态载荷作用下新型ITI牙种植体模型跌落微动试验中的应用。结合传统ITI和Nano-Tite种植体的特点，构建了一种新型凹孔种植体。与传统的ITI种植体模型相比，通过显式动力学有限元分析，新的种植体模型的微动显著减少。通过均匀设计试验，采用动态有限元分析方法，计算了全模型的最大微动量。最后，在所有的实验模拟中，导致最小的微动的主设计被选为设计的先进模型。相对于与45.11 μ m的微动相关联的原始设计，改进版本的微动为31.37 μ m，改进率为30.5%。
The main aim of this article was to introduce the application of a uniform design for experimental methods to drop the micromotion of a novel ITI dental implant model under the dynamic loads. Combining the characteristics of the traditional ITI and Nano-Tite implants, a new implant with concave holes has been constructed. Compared to the traditional ITI dental implant model, the micromotion of the new dental implant model was significantly reduced by explicit dynamic finite element analysis. From uniform design of experiments, the dynamic finite element analysis method was applied to caluculated the maximum micromotion of the full model. Finally, the chief design in all the experiment simulations which cause the minimum micromotion is picked as the advanced model of the design. Related to the original design, which was associated with a micromotion of 45.11 mu m, the micromotion of the improved version was 31.37 mu m, for an improvement rate of 30.5%.
