Comparing HANT and Conventional NiTi Archwires in Alignment

All patients were treated with 0.022-inch MBT brackets and sequential NiTi/HANT archwires. A 0.014 NiTi wire was placed initially, followed by monthly archwire changes if no deflection remained. Digital scans were taken from baseline (T0) to 6 months (T6) to measure alignment using Little's irregularity index. Pain was recorded at 24 hours, 3 days, and 1 week with a visual analog scale. CBCT scans before and after alignment assessed root length and alveolar bone changes, with standardized 3D superimpositions ensuring accurate comparisons.
