摘要
目的 比较澳丝、美国正畸钢丝、仿澳丝、国产不锈钢丝、经热处理国产不锈钢丝的刚度、弹性、强度、抗疲劳性能 ,为临床合理选用正畸钢丝提供依据。方法 对上述 5种临床常用正畸钢丝的弹性模量、弹性极限、回弹角、抗拉强度、扭转强度、疲劳强度等机械性能进行测试和比较。结果 得出 5种正畸钢丝的刚度、弹性、强度、抗疲劳性能等比较数据。结论 在临床上应该根据不同矫治时机的需求以及钢丝的不同特性合理选用钢丝。
Objective To invesbigale the rigidity,elasticity,strength and fatigue properties of five orthodontic wires (Australian orthodontic wire,Elgiloy yellow wire of RMO,Chinese orthodontic wire,Chinese stainless steel wire and Heated Chinese stainless steel wire),and give a support for scientific selection of orthodontic wires in clinic.Methods The specimens of the five wires were tested and compared for their elastic modulus,elastic limit,tensile strength,reverting angle,torsional strength and fatigue strength.Results The data on 6 mechanical properties of 5 different orthodontic wires were obtained.Conclusion The wires should be selected according to clinical needs and wires properties.
