Introduction: The purpose of this prospective, double-blind, randomized clinical trial was to compare the clinical efficiency of nickel-titanium and niobium-titanium-tantalum-zirconium (TiNbTaZr) archwires during initial orthodontic alignment. Methods: All subjects (ages between 12 to 20 years old) underwent nonextraction treatment using .022 brackets. All patients were randomized into 2 groups for initial alignment with .016 NiTi archwires (n=14), or with .016 TiNbTaZr archwires (n=14). Digital scans were taken during the course of treatment; these scans were used to compare the improvement in Little’s Irregularity Index and the changes intercanine and intermolar widths. Results: There was approximately a 27% reduction in crowding during the first month by the use of .016 TiNbTaZr (Gummetal) wire, and an additional 25% of decrease in crowding was observed during the next month. There was no significant difference between the two treatment groups in the decrease in irregularity over time (P=0.29). There was no significant difference between the two groups in the changes in intercanine and intermolar width (P=0.80). Conclusions: It can be concluded that Gummetal wires and conventional NiTi wires possess a similar ability to align teeth, and Gummetal wires have additional advantages over conventional NiTi such as formability and use in nickel allergy patients.
