1.1 Aim:To assess the various methods of extrusion of tooth 1.2 Objective:To assess different applications of extrusion in every aspect of operative treatment. Extrusion is widely used in orthodontic therapy, This article focuses on the use of extrusion in other aspects as well. 1.3 Background:Introduction For many years, the removal of bone or gingival tissues has been the most common method used for crown-lengthening surgery. This surgical procedure usually causes an uneven contour of the gingival margin in the anterior region. In addition, as fear of pain is one of the major problems in dentistry, patients often reject this traumatic surgery. In recent years, as an alternative to such a highly invasive technique, mini screws have been used as temporary anchorage devices (TAD) for several orthodontic tooth movements including forced eruption. However, there are other methods developed in recent years. 1.4 Reason:Hence, this comprehensive literature review aims at understanding the various methods of extrusion of teeth.
