1. A method for restoring an improper morphology of alveolar bone around a tooth in a patient, using an orthodontic bracket with an arch wire, the bracket having a substantially vertical element having a slot formed therein for receiving the arch wire, and a substantially horizontal element connected to the vertical element with the vertical element being positioned gingivally with respect to the horizontal element, the horizontal element having opposing first and second ends extending away from the vertical element and defining a pair of spaced-apart wire engaging points, the slot in the vertical element being vertically spaced apart from the horizontal element, the method comprising the steps of:
applying the bracket to the tooth; installing the arch wire within the slot in the bracket; and applying a force to the bracket by attaching a force transmitting member to the bracket initially causing the crown of the tooth to tilt relative to a vertical axis through the tooth and thereby causing the arch wire to contact one of the wire engaging points and a part of the vertical element defining an upper portion of the slot that is distal to the one wire engaging point such that further force applied by the force transmitting member causes a reverse tilt of the root of the tooth relative to the vertical axis, thereby inducing movement of the root causing orthoeruption, correcting the position of the tooth and restoring said morphology of said alveolar bone. |
