Total recall: an update on orthodontic wires.

: Orthodontic therapy is a force management procedure largely based on use of arch wires for storing and distributing biologically tolerable forces by means of which position of teeth is altered. Advances in material science and technology has resulted in an array of newer arch wire materials, opening new vistas, in orthodontic treatment. Materials with widely diverging properties are in the market today and their usage has profound implications on appliance mechanics, and are very much different from stainless steel which is popular even today. The dentists who practise orthodontics have to therefore clearly outline the phases of treatment and select the arch wire most suited for attaining specific treatment goals.
