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 ...

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.

Force relaxation in orthodontic arch wires

American Journal of Orthodontics, 1984
Wire selection for use in an orthodontic appliance is usually based upon clinical impressions. This is unsatisfactory. A far better basis for selection would be measured values of the forces exerted by the arch wire, both initially on insertion of the appliance and their variation with time as a result of tooth movement and of stress relaxation in the ...

Noncontact microstrain measurements in orthodontic wires

Journal of Biomedical Materials Research, 1995
AbstractA technique is presented that allows for highly sensitive and highly accurate measurements of microstrain in biomaterials. It is particularly useful for measuring strains in materials where the use of conventional extensometers or strain gauges is impracticable, such as in reinforcement fibers and orthodontic wires and in hostile environments ...

Corrosion of silver soldered orthodontic wires

Acta Odontologica Scandinavica, 1982
The amounts of metals liberated from silver soldered stainless steel and cobalt-chromium orthodontic wires were measured. Measurements were taken after 3 days and 24 days immersion in 0.9% sodium chloride solution. High amounts of copper and zinc and some cadmium from the silver solder were found.

Bending Deformation Studies of Orthodontic Wires

Journal of Dental Research, 1978
Bending deformation has been measured for orthodontic wires ranging in diameter from .010 to .051 inch. Results establish a revised expression for Young's modulus and show that either the stiffness tester or the torque meter will yield essentially the same measured values of bending properties. The dependence of test span length in determining Young's
