Orthodontic anterior intrusion for correcting deep bites often constitutes an integral part of orthodontic treatment in order to improve sagittal and vertical incisor relationships, in cases of pseudo-deep overbite, where the anteriors are supraerrupted true intrusion of the incisors is indicated and also in patients with gummy smiles and periodontal compromised teeth to correct the gingival line and restore the esthetics of smile. Intrusion is mainly achieved by use of various loop mechanics or implant mechanics or differential force concept given by beggs. In this article different mechanics for intrusion in beggs technique and PEA (Pre Adjusted Edgewise) technique are mentioned.
