The finite element analysis method and a two-dimensional idealization were used to conduct a parametric study of the effect of the archwire slot (or insert) profile on the stresses in, deformation of, and efficiency of a model of a bonded edge-wise "combination-materials" type of orthodontic bracket. The results are consistent with a priori expectations and are qualitatively the same as those obtained by previous workers who used the two-dimensional photoelasticity stress analysis method. The results thus highlight a possible approach to improving the clinical performance of these brackets.
采用有限元分析方法和二维理想化方法，对正畸托槽粘结式“组合材料”类型模型中弓丝槽（或插入物）轮廓对应力、变形及效率的影响进行了参数研究。结果与先验预期一致，在定性上与先前使用二维光弹性应力分析方法的研究人员所得到的结果相同。这些结果因此突出了一种改善这些托槽临床性能的可能方法。
