Comparison of arch width and depth changes and pain/discomfort with conventional and copper Ni-Ti archwires for mandibular arch alignment

Copper Ni-Ti archwires were no more efficient than Ni-Ti archwires in leveling of the mandibular anterior teeth changes in arch dimensions in patients with moderate dental irregularity. Changes in mandibular arch dimensions were similar in the copper Ni-Ti and Ni-Ti groups.
