摘要： 目的:采用三维有限元分析方法,研究双槽沟被动自锁系统作用于扭转牙的力学性能及变化规律。方法:选择DamonQ托槽作为研究对象,建立DamonQ及不同尺寸弓丝的三维有限元模型,根据实验分组进行装配、网格划分、参数设定及力量加载,最终分析所得数据,绘制曲线图。结果:单丝组中,扭转力矩值随弓丝尺寸的增大而增大。双丝组中,主弓丝尺寸不变,扭转力矩值随辅弓丝尺寸增大而增大;当辅弓丝尺寸相同时,扭转力矩值与主弓丝尺寸成正相关。主槽沟中弓丝尺寸一致时,单丝组扭转力矩值明显小于双丝组。结论:DamonQ托槽双丝的扭转性能明显高于单丝,合理使用辅助性水平槽沟有助于矫正牙扭转。

Abstract: Objective: To discover the mechanical property and the change rule about the tooth rotation of the passive double colpus of self-ligating system by using 3-D finite element analysis. Method: Damon Q bracket was selected as the objective. 3-D finite element models of the Damon Q and the wire with different size were established. Researchers assembled the models, did the mesh division, set up parameter and loaded power. After that, data were analyzed and graphs were drawn. Result: When assembled a single wire, the torsional torque value increased with the size of wire. In the double wire group, the torsional torque value increased with the size of assistant wire under the same main arch wire; when the assistant wire was immutable, there showed a positive correlation between the torsional torque value and the size of main arch wire. When using the same size of wire in the main colpus, torsional torque value of the single wire group was much less than the double wire group. Conclusion: The torsional property of the double wire group was much higher than the single wire group. Logical use of the assistant-horizontal colpus would be good for correcting the rotated teeth.
