Ideal requirements of Orthodontic arch wires

Orthodontic treatment with arch wires has got inevitable features of wires that has to be remembered and some of these features are given below:-

  • Spring Back:It is the measure of how far a wire can be deflected without causing permanent deformation.It is also called elastic deflection.
  • Stiffness:The presence of a low stiffness provides the ability to apply lower forces and a more constant force over time.
  • Formability:The arch wire has to exhibit high formability so as to bend into desired configuration such as coils,loops etc without fracturing the wire.
  • Resilience:It is the amount of force the wire can withstand before permanent deformation.
  • Biocompatibility and Environmental stability:Orthodontic arch wires should exhibit resistance to tarnish and corrosion and should be non-toxic.The material should maintain its desirable properties for extended periods of time after manufacture.
  • Joinability:The wire should be amenable to soldering and welding
  • Friction:The Arch wire should provide least friction at the wire-bracket interface.
