Transposition is described as an interchange in the position of two teeth within the same quadrant of the dental arch. Canine transposition is reportedly the most common transposition in human dentition. The incidence of maxillary canine-premolar transposition is reported to be 0.135-0.510%. Although the exact mechanism of canine transposition is unclear, it seems to be closely related to genetically influenced, retained deciduous canine, and a history of trauma. In this article, we focus on the classification, incidence, etiology, and treatment modalities of tooth transposition. We hope this information will help clinicians treating patients with this kind of dental anomaly.
牙齿换位被描述为牙弓同一象限内两颗牙齿位置的互换。据报道,尖牙换位是人类牙列中最常见的换位情况。上颌尖牙与前磨牙换位的发生率据报道为0.135% - 0.510%。尽管尖牙换位的确切机制尚不清楚,但似乎与遗传影响、乳牙滞留以及外伤史密切相关。在本文中,我们重点关注牙齿换位的分类、发生率、病因及治疗方式。我们希望这些信息能帮助临床医生治疗患有此类牙齿异常的患者。
