摘要

摘要: 目的测量不同组合的双丝弓在不同自锁托槽中静摩擦力和动摩擦力的大小.方法于标准模型上分别粘贴右上象限的Damon Q自锁托槽记为A组、3M Smart clip自锁托槽记为B组、非凡Quick 3.0自锁托槽记为C组作为实验对象,采用0.012英寸与0.016英寸超弹镍钛圆丝组合和0.014英寸与0.014英寸的超弹镍钛圆丝组合,模拟弓丝在托槽内的滑动,测量托槽与弓丝间摩擦力的变化,从而探讨不同组合的双丝弓在不同自锁托槽中摩擦力大小的差异.结果使用0.014与0.014英寸超弹镍钛圆丝组合,静摩擦力大小为A组

Abstract: Objective To measure the dynamic and static frictional resistances between different self-ligating orthodontic brackets and different combination of tandem archwires. Methods On standard model the upper right quadrant Damon Q self-ligating brackets was pasted as team A, 3M Smart clip self-ligating brackets as team B and Forestadent Quick 3.0 self-ligating brackets as team C respectively. Nickel-titanium archwires of 0.012 inch and0.016 inch and two nickel-titanium archwires of 0.014 inch were applied to simulate sliding in the brackets and measure the friction changes in brackets and archwires, so as to explore the frictional resistance between different combination of the tandem archwires and different self-ligating brackets. Results When using the combination of two 0.014-inch nickel-titanium tandem archwires, the static frictional resistances was significantly different(P<0.05):team A
