Bonded orthodontic retainers: The wire-composite interface
American Journal of Orthodontics and Dentofacial Orthopedics, 1997The bonded orthodontic retainer constructed from multistrand wire and composite is an efficient esthetic retainer, which can be maintained long-term. Clinical failures of bonded orthodontic retainers, most commonly at the wire/composite interface, have been reported. This in vitro investigation aimed to evaluate selected multistrand wires and composite

[Super-elastic wire used in orthodontics].
Mondo ortodontico, 1990The Authors describe the unusual super-elastic property of the Japanese NiTi alloy wire. They examine the clinical applications in relation to the relatively constant force delivered during the deactivation and in relation to the new possibility to shape wire which are offered by the Archmate Wire Bender.

Alternative beta-titanium alloys for orthodontic wires
Dental Materials, 1987Abstract Ti-11.5Mo-6Zr-4.5Sn metastable beta-titanium alloy (TMA, Ormco) supplements the stainless steel and nickel-chromium-cobalt alloys traditionally used in orthodontic practice. The titanium wire has a lower modulus of elasticity (E) and a higher yield strength to modulus ratio (YS/E), which results in clinically desirable lower forces and ...

The chloride corrosion behaviour of four orthodontic wires
Journal of Oral Rehabilitation, 1983SummaryPotentiodynamic cyclic polarization of four orthodontic alloys (wires), namely Permachrome, Elgiloy, a β‐titanium alloy and Nitinol in a 1 % NaCl solution within −500 mV and +300 mV (SCE) indicated the first three alloys to be passive whereas breakdown of passivity was observed on Nitinol.

In vitro investigation into the biological assessment of orthodontic wires
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthop�die, 1998The alloys used in orthodontics are subject in the moist environment of the oral cavity to various corrosion processes. If the products of the corrosion are introduced into a biological system they may cause changes. In the present investigation the corrosion rate of 23 different orthodontic wires (preformed arch wires and straight wires) made from 5 ...

Properties of superelastic wires and their relevance to orthodontic treatment
The European Journal of Orthodontics, 1995In this study tools were developed to test and compare levelling archwires that the manufacturers claim to have superelastic properties. As the classic spring model and Hook's law cannot be applied, new parameters had to be found. It could be shown that three parameters are necessary to describe a superelastic archwire adequately: the distinctiveness ...

Comparison of bending and tension tests for orthodontic wires
American Journal of Orthodontics, 1986Stainless steel, cobalt-chromium-nickel (Elgiloy), nitinol, and beta titanium wires with diameters from 0.010 to 0.040 inch and in rectangular sizes from 0.017 X 0.025 to 0.019 X 0.025 inch were evaluated with the American Dental Association specification no. 32 bending test and the conventional tension test.

Mechanical properties and clinical applications of orthodontic wires
American Journal of Orthodontics and Dentofacial Orthopedics, 1989This review article describes the mechanical properties and clinical applications of stainless steel, cobalt-chromium, nickel-titanium, beta-titanium, and multistranded wires. The consolidation of this literature will provide the clinician with the basic working knowledge on orthodontic wire characteristics and usage.

Simulation of the Superelastic Response of SMA Orthodontic Wires
Journal of Biomechanical Engineering, 1998Shape-memory alloys have properties that make them well suited to a variety of applications. One application for which their unique combination of properties (large elastic range, low modulus of elasticity, ability to deliver nearly constant forces over a wide range of deformations) seems ideally suited is for orthodontic retraction appliances where ...
