This study evaluated the effect of heat treatment on 0.036" diameter stainless steel wire. Forty wires were bent into arch forms (20 experimental and 20 control). The arch width changes were measured and the forces generated were determined over an eight week period. Heat treatment resulted in immediate and significant expansion (p < 0.001) followed by stabilization of arch width. The control wires continued to expand throughout the study. The force generated by the control group and experimental group expansion was capable of producing tooth movement.
本研究评估了热处理对直径0.036英寸不锈钢丝的影响。四十根钢丝被弯成弓形（20根实验组和20根对照组）。在八周的时间内测量弓形宽度的变化并确定产生的力。热处理导致立即且显著的扩张（p < 0.001），随后弓形宽度稳定。对照组钢丝在整个研究过程中持续扩张。对照组和实验组扩张产生的力能够引起牙齿移动。
