| Abstract: | 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. |
| Keywords: | Orthodontic wire Mechanical property Testing |
