Evaluation of pain, alignment efficiency, and post alignment anterior torque between I –Archwires and superelastic NiTi wires: A comparative study

: to compare the aligning efficiency, pain experienced by patient during alignment and post third order values of anterior teeth in I arch (study) group conventional NiTi (control) wire group. A prospective clinical study. total 40 dental arches (maxilla/mandible) were divided into 2 study groups with 20 each based on selection criteria. Group I. Twenty (maxillary/mandibular) having 0.018” preadjusted appliance (MBT) brackets (ORMCO), aligned –arch 0.016”x0.014” copper wires. II. ORMCO round super elastic archwires. -arch (study group) was more efficient compared superelastic (control lower are statistically significant. There torque expression I-arch as The subjects lesser
