Several different metals are used in orthodontic appliances, and their physical properties and mechanical behavior are the very life blood of orthodontic therapy. Recent advances in orthodontics have resulted in a varied array of wires that exhibit a wide spectrum of properties. Up until the 1930’s the only orthodontics wires available were made of gold.

  • Austenitic stainless steel, with its greater strength, higher modules of elasticity, good resistance to corrosion and moderate cost, was introduced as an orthodontic wire in 1929 and shortly afterwards gained popularity over gold.
  • Since then several other alloys with desirable properties have been adopted in orthodontics. These include cobalt-chromium, nickel titanium, beta-titanium, and multi-stranded stainless steel wires.
