An efficient biomechanical approach for the management of an impacted maxillary central incisor

Am J Orthod Dentofacial Orthop. 2014 Aug;146(2):249-54. doi: 10.1016/j.ajodo.2013.09.017.

Abstract

Treatment of an impacted maxillary central incisor poses a unique challenge to the orthodontist because of its position within the esthetic zone, requiring careful management of the soft tissues and an effective biomechanical setup for alignment. This article describes a novel method of extending an extrusion wire from cross tubes attached on the base archwire for forced eruption of impacted central incisors. The effectiveness and versatility of this method are demonstrated with 2 patients.
