ABSTRACT
There are many nickel-titanium alloy wires available in the market. Nevertheless not all of them possess the ideal characteristics of shape memory and super-elasticity to be used in orthodontic treatment. The aim of the present study was to find austenitic final temperature of these archwires so as to determine the transformation phase in order to better use them in orthodontics.
Methods: Eleven nickel-titanium orthodontic wires were selected. Transformation phase was assessed using differential scanning calorimetry method.
Conclusions: The present study illustrates how some orthodontic Ni-Ti wires elicit results contrary to those advertised.
