Nitinol Archwires

The introduction of superelastic Nitinol® (UNS N01555) wires in the field of orthodontics more than a decade ago was an “unbelievable blessing,” says Dr. Robert Cram, past president of the Canadian Association of Orthodontists. Superelastic wires stretch easily when they are cool but spontaneously shrink when they are warmed up. This property can be used to progressively pull teeth into their proper position.
