Tensile properties of orthodontic wire

American Journal of Orthodontics, 1977
1. Wires with a range of tensile properties are available for construction of a Stage 1 arch wire in the Begg orthodontic appliance. 2. Over a period of 3 days, a detectable amount of stress relaxation occurs in some orthodontic wires loaded initially to 20 kg.

Comparative range of orthodontic wires

American Journal of Orthodontics and Dentofacial Orthopedics, 1986
ADA specification No. 32 for determining the range (elastic limit) of orthodontic wires uses the bending of a wire section treated as a cantilever beam. An alternative method for defining the range of orthodontic wires proposed by Waters (1981) is to wrap wire sections around mandrels of varying diameters and measure the deformation imparted after ...

The corrosion of orthodontic wire

The European Journal of Orthodontics, 1988
The corrosion of stainless steel orthodontic wire was investigated using the electrochemical technique of polarization resistance. A potentiostat was used to apply small perturbations about the corrosion potential and the resultant current was measured.
