Official Title: Evaluation of Pain, Discomfort and Functional Impairment Associated With the Two-step Retraction Technique Anchored With Transpalatal Arches Versus the en Masse Retraction of Upper Anterior Teeth Anch

Brief Summary: Thirty-eight patients requiring extraction of maxillary first premolars will participate in the study. They will be divided randomly into two groups: an en-masse retraction group and a two-step group. In each group, anterior teeth retraction will be initiated after completion of the leveling and alignment phase via closed nickel-titanium coil springs applying 150 g of force per side, Mini-implants will be used as an anchor unit in the en-masse retraction group, and TPA in the two-step's retraction group.The levels…
