Transposition is an anomaly of tooth position, the most frequent of which involves the canine and the first maxillary premolar. We describe the orthodontic treatment of a unilateral transposition of an upper canine and an upper right first premolar in the permanent dentition.
A 12-year-old Caucasian boy presented with transposition of his upper right canine and upper right first premolar. He had combined surgical-orthodontic treatment to correct the transposition and to obtain a Class I relationship between the molar and canine. This treatment resolved the dental crowding and achieved good functional and aesthetic results.
In transposition, the choice of the most suitable treatment depends on the occlusion, level of dental crowding, aesthetics, position of the radicular apices, and the specific needs of the patient. In this case, orthodontic alignment of the transposed teeth into their physiological position achieved all of our objectives and our patient was satisfied with the aesthetic results obtained.
牙齿易位是一种牙齿位置异常，其中最常见的是尖牙与上颌第一前磨牙易位。我们描述了一例恒牙列中上颌尖牙与右上第一前磨牙单侧易位的正畸治疗情况。
一名12岁的白种男孩，右上尖牙与右上第一前磨牙发生易位。他接受了正畸联合外科治疗，以纠正易位并使磨牙和尖牙达到I类关系。该治疗解决了牙列拥挤问题，并取得了良好的功能和美观效果。
在牙齿易位的治疗中，选择最合适的治疗方法取决于咬合情况、牙列拥挤程度、美观性、根尖位置以及患者的特殊需求。在本病例中，将易位牙正畸排齐至生理位置实现了我们所有的治疗目标，患者对所获得的美观效果也很满意。
