Comparative Assessment of Wire Deformation, Breakage, Frictional Resistance, and Patient Discomfort in Orthodontic Archwires: A Clinical Study

A BSTRACT Background: Orthodontic archwires’ characteristics are known to have an effect on the effectiveness, duration, and comfort of orthodontic treatment. Despite the widespread use of nickel-titanium (NiTi), SS, and TMA wires, comparative testing on wear, breakage, friction, and discomfort among patients has not been conducted. The study is still in its early stages. Aim: To check pain and deformation of patients and also for frictional resistance on various arches at the end of 6 weeks. Methodology: Across three groups (NiTi, SS, TMA), 25 patients were included in the study that evaluated the archwire deformation and frictional resistance. A sense of distress occurred at 24 h, 3 days, and 1 week. The statistical methods used were Chi-square, analysis of variance (ANOVA), and Kaplan–Meier tests. Results: NiTi wires had the lowest level of deformation and breakage ( P = 0.038). In contrast, SS wires had the greatest frictional resistance ( P 0.001) among all other types. Time exhibited a gradual decrease in pain. Conclusion: The results indicate that a greater number of NiTi wires are more comfortable and durable, whereas SS wire has fewer breaks and friction.
