| 摘 要： | 本文通过模拟上颌前牙矫治实验，测定了目前国内常用几种弓丝的弹性性能。结果显示不锈钢类弓丝刚度大，其中澳丝刚度最大。镍钛丝和带垂直曲的弓丝刚度小，能提供较持续的矫治力。0．014中国镍钛丝具有超弹性性能，而0．016中国镍钛丝在0～250g范围内未显示出超弹性。

| Abstract: | In this study, methods were develoPed to test and compare leveling archwiresthat commonly used in domestic practice. The results showed that the stainless steel archwtres were stiff. The Ni-Ti wires and the wires with loops were nexible and cou1d delivermore constant force. The 0' 014 Chinese Ni-Ti wires demonstrated the superelastic proper-ty, but 0. 016 Ni -Ti wires did not appear the same property bef0re they generated 250gforce. |
