摘要

A method for quantifying the torsional elastic properties of orthodontic archwires was investigated. Three wire sizes (.018 inch, .017 inch x.025, and .019inch x.025) were tested for three different alloys: stainless steel S.S., beta titanium B-Ti, and nickel-titanium Ni-Ti. The shear modulus (G) was determined dynamically using a torsion pendulum. The torsional yield strength (Tys) was determined using a static torsion test that generated torque (T) versus angular deflection (phi) tracings. The three basic torsional elastic properties (strength, stiffness, and range) were calculated for each of the wires from G, Tys, and precise dimensional data. The Ni-Ti wire had the greatest range and the least stiffness. S.S. archwire showed the greatest stiffness and the least range. The properties of B-Ti fell
