Abstract

Aim: The aim of the study is to compare the efficiency of six-stranded coaxial tubular superelastic nickel-titanium (NiTi) archwire and a single-stranded wire in relieving anterior mandibular crowding.

Materials and methods: This double-blind randomized study included 40 patients, categorized into two groups: Sentalloy round group and Speed tubular supercable group (20 each). After taking alginate impressions, the allocated archwire was engaged. With a digital caliper, intercanine, interpremolar, and intermolar width were recorded on the study models, immediately and at 4, 8, and 12 weeks stages. The Statistical Package for the Social Sciences (SPSS) version 20 was used for analysis.

Results: The measured parameters were increased in both the groups, with the difference being insignificant statistically.

Conclusion: Superelastic coaxial NiTi wires show better efficiency in relieving anterior crowding than single-stranded NiTi wire.

Keywords: Anterior crowding; digital caliper; intercanine width; nickel–titanium wire; superelastic coaxial nickel–titanium wire.
