Frictional resistance is a critical factor influencing the efficacy of orthodontic treatment. Archwire-ligature combinations play a significant role in determining frictional forces within the orthodontic system. This study aimed to conduct a comparative analysis of the frictional resistance exhibited by various archwire-ligature combinations commonly used in orthodontics.
A total of five archwire-ligature combinations were evaluated in this study: stainless steel archwire with elastic ligatures, stainless steel archwire with metal ligatures, nickel-titanium archwire with elastic ligatures, nickel-titanium archwire with metal ligatures, and beta-titanium archwire with metal ligatures. Frictional resistance was measured using a universal testing machine under standardized conditions, with a constant load applied to simulate clinical conditions.
The frictional resistance varied significantly among the different archwire-ligature combinations. The mean frictional resistance values (in arbitrary units) recorded were as follows: stainless steel archwire with elastic ligatures (X), stainless steel archwire with metal ligatures (Y), nickel-titanium archwire with elastic ligatures (Z), nickel-titanium archwire with metal ligatures (A), and beta-titanium archwire with metal ligatures (B). Statistical analysis revealed that combination A exhibited the lowest frictional resistance, followed by combination B, combination Z, combination X, and combination Y.
The choice of archwire-ligature combination significantly affects the frictional resistance within the orthodontic system. Nickel-titanium archwires combined with metal ligatures demonstrated lower frictional resistance compared with stainless steel archwires, regardless of the ligature type. Among the combinations tested, nickel-titanium archwire with metal ligatures exhibited the lowest frictional resistance, suggesting its potential for reducing friction and improving treatment efficiency in orthodontic practice.
摩擦力是影响正畸治疗效果的关键因素。正畸弓丝与结扎丝的组合在确定正畸系统内的摩擦力方面起着重要作用。本研究旨在对正畸中常用的各种弓丝与结扎丝组合所表现出的摩擦阻力进行比较分析。
本研究共评估了五种弓丝与结扎丝组合：不锈钢弓丝搭配弹性结扎丝、不锈钢弓丝搭配金属结扎丝、镍钛弓丝搭配弹性结扎丝、镍钛弓丝搭配金属结扎丝以及β钛弓丝搭配金属结扎丝。在标准化条件下使用万能试验机测量摩擦阻力，施加恒定载荷以模拟临床情况。
不同的弓丝与结扎丝组合之间摩擦阻力差异显著。记录的平均摩擦阻力值（单位为任意单位）如下：不锈钢弓丝搭配弹性结扎丝（X）、不锈钢弓丝搭配金属结扎丝（Y）、镍钛弓丝搭配弹性结扎丝（Z）、镍钛弓丝搭配金属结扎丝（A）以及β钛弓丝搭配金属结扎丝（B）。统计分析表明，组合A的摩擦阻力最低，其次是组合B、组合Z、组合X和组合Y。
弓丝与结扎丝组合的选择对正畸系统内的摩擦阻力有显著影响。与不锈钢弓丝相比，无论结扎丝类型如何，镍钛弓丝与金属结扎丝组合的摩擦阻力更低。在所测试的组合中，镍钛弓丝搭配金属结扎丝的摩擦阻力最低，表明其在正畸实践中具有降低摩擦和提高治疗效率的潜力。
