The aim of this article is to describe a case of a young orthodontic patient in which an impacted maxillary canine was repositioned in the central incisor position. A severe resorption of the root of the central right maxillary incisor by ectopic eruption of the impacted right maxillary canine is described. The canine was repositioned in the incisor's position to avoid resorption of the roots of the adjacent teeth during the disinclusion. The central incisor was extracted and the canine was extruded by a closed eruption technique. When the canine eruption was complete, the tip, the torque and the morphology of the canine were modified in order to make it look like an incisor. Nowadays the therapy with dental implants is the best choice, if the position of impacted teeth is difficult to reach. This case report describes a successful management of an impacted upper right canine aligned in the upper right central incisor position. Accurate diagnosis, conservative management of the soft tissues, anchorage unit and the direction of the orthodontic traction are important factors for the success treatment.
本文旨在描述一例年轻正畸患者,其中一颗上颌阻生尖牙被重新定位到中切牙位置。描述了因右上颌阻生尖牙异位萌出导致右上颌中切牙根严重吸收的情况。为避免在解除咬合期间相邻牙齿牙根吸收,将尖牙重新定位到中切牙位置。拔除中切牙,并通过闭合萌出技术将尖牙牵出。当尖牙萌出完成后,对尖牙的牙尖位置、转矩和形态进行调整,使其看起来像一颗中切牙。如今,如果阻生牙的位置难以到达,种植牙治疗是最佳选择。本病例报告描述了右上颌阻生尖牙成功排列到右上颌中切牙位置的治疗过程。准确的诊断、软组织的保守处理、支抗单位以及正畸牵引的方向是成功治疗的重要因素。
