矫治力与弓丝与托槽产生的摩擦力之间的关系影响着矫直过程中弓丝的滑动。本研究的目的是评价美观的小镍钛(Ni-Ti)金属丝受力与摩擦的关系。使用了五根美观的金属丝(三根涂层和两根电镀)和两根细小的普通镍钛金属丝(0.012英寸和0.014英寸)。按国际标准化组织15841标准进行三点弯曲试验和牙弓模型的拔牙试验，其中牙弓模型的侧切牙位移量分别为0.5、1.0、2.0和3.0 mm。在位移小于1.0 mm时，所有钢丝的卸载弯曲力都大于摩擦力，而在位移大于2.0 mm时，所有钢丝的摩擦力都大于卸载弯曲力。当从近端托槽移位超过1.0 mm时，牙弓可能会扩张。马氏体型0.014英寸镍钛钢丝的摩擦力明显大于其他美容钢丝和奥氏体丝的摩擦力。在位移大于1.0 mm的情况下，应使用摩擦力最小的钢丝。
The relationship between orthodontic force and friction produced from an archwire and brackets affects the sliding of the wire in the leveling stage. The purpose of this study was to evaluate the relationship between force and friction in a small esthetic nickel-titanium (Ni-Ti) wire. Five esthetic wires (three coated and two plated) and two small, plain Ni-Ti wires (0.012 and 0.014 inches) were used. We performed a three-point bending test according to ISO 15841 and the drawing test with a dental arch model designed with upper linguoversion of the lateral incisor in the arch (displacements of 0.5, 1.0, 2.0 and 3.0 mm), and evaluated the relationship between them. Unloading bending forces of all wires at displacements of less than 1.0 mm were larger than friction forces, but all friction forces at displacements exceeding 2.0 mm were larger than unloading bending forces. The arch likely expands when displacement from the proximal brackets exceeds 1.0 mm. The friction force of a martensite 0.014-inch Ni-Ti wire was significantly greater than those of the other esthetic and austenitic wires. A wire with the smallest possible friction force should be used in cases with more than 1.0 mm displacement.
