Rotations are mesiolingual or distobuccal intra-alveolar displacement of tooth around their long axis. Canine or premolars must often be derotated during fixed appliance therapy. Derotation of posterior teeth provides space which can be utilized for relieving crowding in the anterior region. By correction of these rotations one to three mm of arch length can be gained per side. Biomechanical principles involve application of single or couple of forces for correction of rotation. Rotated teeth can be corrected by removable, semifixed or fixed appliance depending upon the severity of rotation. Whatever the technique used, derotation especially of posterior teeth should be achieved quickly so that the gained space can be used for relieving crowding.
