Clinical studies have focused on mechanical properties and effects on tooth alignment, biofilm formation and Ni ion release. NiTi archwires are also evaluated in terms of biological properties from a clinical perspective. The consequences of deflection heat treatment, aging on mechanical properties are described. The surface modification studies are reviewed. The effects of surface roughness, brackets and environment on friction are discussed. The main factors affecting corrosion are stress, temperature and pH of the environment. ![]() The effects of processing parameters, stress and temperature on phase transformations and corrosion are summarized. Analysis of the research profile showed that mechanical properties as a research topic constituted 25.9 % of the research articles published in last two decades. This review presents the concepts related to NiTi archwires from the materials science and engineering perspective. ![]() ASTM A673/A673M Standard Specification for Sampling Procedure for Impact Testing of Structural Steel 24. ASTM A668/ A668M Standard Specification for Steel Forgings, Carbon and Alloy, for General Industrial Use 23. Nickel-titanium (NiTi) archwires have been widely used in orthodontic treatments at the aligning and leveling step which is the initial stage of the treatment. ASTM A618/A618M Standard Specification for Hot-Formed Welded and Seamless High-Strength Low-Alloy Structural Tubing 22. ![]()
