Mechanical behavior of thermo-responsive orthodontic archwires
Dental Materials, 1996This investigation was conducted to describe the mechanical behavior of thermo-responsive nitinol archwires in flexure at 5 degrees and 37 degrees C.Four same-sized (but different force level) rectangular archwires were examined using a three-point bend test. Samples were tested at 5 degrees and 37 degrees C.

Metal release from heat-treated orthodontic archwires
Acta Odontologica Scandinavica, 1987Stainless steel and cobalt-chromium orthodontic archwires were subjected to an immersion corrosion test. Wires in the as-received state and wires subjected to a 1-min heat treatment at different temperatures were tested. Iron from the stainless steel and cobalt from the cobalt-chromium product were analyzed in artificial saliva after 1 week of ...

Lingual orthodontics (Part 2): Archwire fabrication
Journal of Orofacial Orthopedics / Fortschritte der Kieferorthopädie, 1999One essential component of a successful lingual treatment concept is the precise calculation and manufacture of individual lingual arch wires. As in several parts of daily life, the use of modern CAD/CAM technology leads in lingual orthodontic treatment to a rationalisation of working processes with maximized precision.

Customized brackets and archwires for lingual orthodontic treatment
American Journal of Orthodontics and Dentofacial Orthopedics, 2003After 20 months of clinical testing and more than 600 bonded arches, brief interim conclusions can be drawn on treatment with a new lingual bracket system, one that differs fundamentally from conventional appliances in both design and manufacture. The demand for maximum individuality is met by using state-of-the-art computer-aided design/computer-aided

Mechanical properties of stainless steel orthodontic archwires
Clinical Materials, 1988Abstract Sixty orthodontic archwire product/size combinations were studied from six manufacturers in simple bending and uniaxial tension. Data were obtained for wire diameters, elastic moduli, yield strength, tensile strength, and elongation at break.

Torsional properties of Ni–Ti orthodontic archwires
Materials Science and Engineering: A, 1999Abstract Commercially preformed edgewise Ni–Ti based archwires are used in orthodontic practice. Two commercially available products were tested in torsion in controlled conditions of moment and temperature, in equipment especially designed to simulate the environments in clinical use.

Bending angle optimization of archwire in orthodontics
Journal of Mechanical Science and Technology, 2012Orthodontics is the branch of dentistry that focuses on the study and treatment of malocclusions. Orthodontic treatments commonly involve the insertion of an archwire made from stainless steel or an alloy onto orthodontic brackets, thereby inducing movement of teeth into desired positions.

Physical Characteristics of Orthodontic Wires and Archwires—Part 1
British Journal of Orthodontics, 1975In Part 1A consideration is given to the relevant elastic properties of orthodontic wires. Tests for evaluating these properties are discussed and details of two new tests are given. Part 1B is concerned with an evaluation of the properties of a number of round and multiple strand orthodontic wires.

Cytotoxicity of orthodontic bands, brackets and archwires in vitro
Dental Materials, 2002In orthodontic therapy, different materials are used and subjected to a damp oral environment, which can modify their properties. In order to evaluate the biocompatibility of metallic and non-metallic orthodontic appliances their in vitro cytotoxicity has been measured.Twenty-eight new and nine clinically used materials, including brackets, molar bands
