Teeth with root fracture may need orthodontic treatment. This case report presents the management of unerupted canines in a patient with previously-healed/untreated horizontal root fracture in the maxillary left central incisor. The malocclusion was treated maintaining pulp vitality considering the principles to improve the eruption path of maxillary canines and move short-rooted teeth. The root-fractured tooth remained symptomless after orthodontic treatment without significant adverse effects, and stayed stable following 2-year follow-up.
牙根折断的牙齿可能需要正畸治疗。本病例报告介绍了一名上颌左中切牙曾有愈合/未治疗的水平牙根折断患者中未萌出尖牙的处理。考虑到改善上颌尖牙萌出路径和移动短根牙的原则，在保持牙髓活力的情况下对咬合不正进行了治疗。正畸治疗后，牙根折断的牙齿无症状，无明显不良反应，随访2年保持稳定。
