Abstract
A beta-titanium alloy wire is used as the force-imparting component in orthodontic appliances. The alloy provides up to a threefold improvement over 18-8 stainless steel wire in load deflection rate and a twofold increase in maximum elastic displacement while providing a low modulus of elasticity and optimum low level force magnitudes. The wire also finds utility as ligature wires, as clasps and related structures in orthodontic and prosthetic appliances and as surgical arch bars for jaw fractures and the like.
