Abstract

Orthodontic alignment of un-erupted dilacerated teeth is challenging, as the bent roots resist forces applied to move them through the bone. Various treatment options are now available to treat this condition including providing prosthesis after extractions and apicectomies. However, to maintain alveolar bone in the area of the un-erupted tooth, especially if the involved tooth is in the anterior segment, the ideal treatment would be to try and bring the tooth in the arch orthodontically. Treatment requires increased time duration, compliance of the patient, and consistent force mechanics. This case report is of a 9-year boy with un-erupted and dilacerated teeth. Orthodontic treatment of prolonged duration was provided to bring these teeth into the arch, improving the esthetics and function.

摘要

未萌出的弯曲牙的正畸排齐具有挑战性,因为弯曲的牙根会抵抗施加于使其穿过骨组织的移动力。目前有多种治疗方案可用于治疗这种情况,包括拔牙后提供修复体和根尖切除术。然而,为了维持未萌出牙区域的牙槽骨,特别是如果受累牙齿位于前段,理想的治疗方法是尝试通过正畸将牙齿排入牙弓。治疗需要更长的时间、患者的配合以及持续一致的力学原理。本病例报告的患者是一名9岁男孩,有未萌出的弯曲牙。通过长时间的正畸治疗将这些牙齿排入牙弓,改善了美观和功能。
