Abstract

Orthodontic archwires are designed to move teeth with light continuous forces. Mechanotherapy depends on both the elastic behavior of the material and the biochemical reaction of the teeth. Stainless steel A. J. Wilcock (Australian) wires have been the backbone of Begg treatment since its inception. During the last few years, two other manufacturers have introduced their brands of high tensile strength stainless steel wires, which they claim to be equivalent to or superior to the Australian wires. This study was undertaken to evaluate and compare the physical properties of high tensile A.J. Wilcock (Australian) wires with the newly introduced high tensile wires and critically assess their claim for superiority. The results obtained were statistically analyzed. It was found that in 0.020″ size, Wilcock Special Plus wire had greater strength and stiffness than the Ortho Organizers wire. In the 0.018″ size, Wilcock Premium and Special Plus wire had greater strength and range and lesser friction and relaxation, while T. P. Premier wires had almost the same strength, but greater friction and relaxation and lesser range. In the 0.016″ size, Wilcock Premium and Special Plus wire had superior stiffness, range and lesser friction and relaxation. In the 0.014″ size, Wilcock Premium and Special Plus wire had greater strength and range while the Ortho Organizers wires had greater stiffness. In the 0.012″ and 0.010″ sizes, the Wilcock Premium Plus and Supreme wires had superior strength and stiffness than the Ortho Organizers wires.
