Orthodontic wire: a continuing evolution

Seminars in Orthodontics, 1997
Wires have substantial structural presence in active and retentive orthodontic therapy. Wires, and auxiliaries fabricated from wire, may deliver force to produce dental displacements, they may attempt to prevent unwanted displacements, or they may simply carry force from one location to another within the dentofacial complex.

The corrosion of orthodontic wire

The European Journal of Orthodontics, 1988
The corrosion of stainless steel orthodontic wire was investigated using the electrochemical technique of polarization resistance. A potentiostat was used to apply small perturbations about the corrosion potential and the resultant current was measured.

Alternative beta-titanium alloys for orthodontic wires

Dental Materials, 1987
Abstract 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 ...

[Super-elastic wire used in orthodontics].

Mondo ortodontico, 1990
The 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.

Flexure Modulus of Orthodontic Stainless Steel Wires

Journal of Dental Research, 1981
The flexure modulus of elasticity of standard stainless steel orthodontic wires was determined by the use of an iterative finite element technique to be 25.4 x 106 psi (175 x 103 MN/m2). This technique accounts for the configurational changes in the test specimens due to the relatively large deflections during the cantilever test.

Chinese NiTi wire—A new orthodontic alloy

American Journal of Orthodontics, 1985
Chinese NiTi wire was studied by means of a bending test to determine wire stiffness, springback, and maximum bending moments. Chinese NiTi wire has an unusual deactivation curve (unlike steel and nitinol wires) in which relatively constant forces are produced over a long range of action. The characteristic flexural stiffness of NiTi wire is determined

Optimal welding of beta titanium orthodontic wires

American Journal of Orthodontics and Dentofacial Orthopedics, 1987
Today the orthodontist is confronted by an array of new orthodontic wire materials that, when applied to appliance design, can vastly increase the flexibility and versatility of therapy. Welded joints, especially for the newer titanium alloy wires, provide a means to extend the useful applications of these materials.

Bonded orthodontic retainers: The wire-composite interface

American Journal of Orthodontics and Dentofacial Orthopedics, 1997
The 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

The mechanical properties of four orthodontic wires and the orthodontic force of a quad helix made of four orthodontic wires

Orthodontic Waves, 2014
Orthod Waves–Jpn Ed 2013;72(2):115–120The purposes of this study were to compare the mechanical properties of four different commercially available wires (two beta-titanium alloy wires, stainless s...
