Abstract: Aim: To compare the load deflection characteristics of laser treated SmartArch wires with other orthodontic wires. Materials and Method: In this in vitro study 10 samples of 3 different orthodontic wires were included. The wire samples were divided into three groups - GroupA: NiTi wire, group B: heat-activated CuNiTi wire and group c: laser-treated CuNiTu wire. The archwires were subjected to 2 and 4 mm of deflection forces and load deflection characteristics were studied on the Instron machine. IBM SPSS software version 23, was used for statistical analysis. The Shapiro-Wilk test for normality and one-way ANOVA test, descriptive statistics were used to compare the means of the three groups. Results: The ANOVA test revealed that wire type had no significant effect (P > 0.05) on the forces produced. At 2 mm loading, the descriptive tests revealed a mean ranging from 0.83 to 0.96 MPa, and at 4 mm loading, 2.64 to 3.53 MPa. However, none of the wires experienced any appreciable increases in force as the deflection increased from 2 to 4 mm. Conclusion: The current study's findings showed that SmartArch wire had a lower load deflection than NiTi wire and heat-activated CuNiTi wire. However, this was not statistically significant.
