Abstract
Introduction Changes in the composition of orthodontic archwires have broadened their properties and characteristics. Along with the composition of wires, properties are affected by the geometric diameter of the wire. Maximum load, ultimate tensile strength, and modulus of elasticity are wire characteristics that can play a role in defining how these wires are able to be used in orthodontic treatment. The objective of this study is to discover if these wires can be used interchangeably based on these tested characteristics and to discover if diameter and shape alters any of these aforementioned alloys’ characteristics. Methods. Tensile testing was conducted on 140 wire samples of Nickel Titanium (NiTi), Titanium Molybdenum (TMA), and Stainless Steel archwires. Within each alloy, dimensions of .016in, .018in, .016x.022in2, and .018x.025in2 were tested. Values for Maximum Load, Ultimate Tensile Strength, and Modulus of Elasticity were obtained. Results. Overall, there were some significant differences seen within alloy groups with different dimensions. Round wires for TMA and NiTi wires showed a significantly higher values ultimate tensile strength and modulus of elasticity when compare to their rectangular counterparts. Stainless steel wires did not show this pattern. Conclusion. Dimension and shape did alter the values for some alloys of wires. Additionally, based on the 3 tested values, we cannot conclude that different alloys can be used interchangeably due to the large disparities in values between the alloy groups.
