摘要： 目的:研究热处理前后多曲簧在开闭口疲劳运动过程中的应力值、位移量及拐点的变化来为临床正畸提供参考。方法:通过拉伸-拐点-压缩实验模拟颊侧多曲簧矫治器在口内开闭口运动过程中的作用,研究不同热处理方式对应力值的影响。结果:通过多曲簧经先加热后弯制处理,可增大其开闭口运动过程的应力值及拐点位移量,其中480 ℃处理效果最明显。多曲簧先弯制后热处理对其拉压过程中拐点位移量基本没有影响。结论:制作颊侧多曲簧时,牙用不锈钢丝可先经480 ℃热处理后再弯制,可提高机械性能。

Abstract: Objective: To evaluate the effect of heat treatment on the forces of buccal multiloop appliance during mouth opening and closing movement. Methods: Stretch-inflection-compression experiment was used to simulate the buccal multiloop appliance during mouth opening and closing movement. Different kinds of heat treatment were discussed in this article. Results: The forces and displacement distance of the buccal multiloop appliance during mouth opening and closing movement increased when it was bended after heat treatment, among which 480℃ was the most obvious. It showed no effect on the displacement distance when it was bended before heat treatment. Conclusion: When making buccal multiloop, the mechanical property of loop can be improved provided the heat temperature was 480℃ and the loop was bended afterwards.
