通过联合缝线的阻生牙移位是一种罕见的特殊的发育异常，原因不明，是下颌犬独有的。上颌犬的迁移更罕见。由于美学和功能的重要性，迁移犬特别重要。上颌侧切牙穿过中腭缝合线从未在文献中报道过。本报告的目的是提出的第一例同时transmigration的侧切牙和犬齿在上颌骨。本文还报道了4例不寻常的上颌和下颌骨单侧犬齿移位的病例，其中1例下颌犬齿移位在正畸牵引后成功出牙。并讨论了转阴的病因及临床注意事项。
Transmigration of an impacted tooth through the symphyseal suture is a rare and special developmental anomaly of unknown etiology that is unique to the mandibular canine. Maxillary canine transmigration is even rarer. Transmigrated canines are particularly significant due to the aesthetic and functional importance. A maxillary lateral incisor crossing the mid-palatal suture has never been reported in the literature. The aim of this report is to present the first case of simultaneous transmigration of a lateral incisor and canine in the maxilla. The paper also reports four unusual cases of unilateral canine transmigration in the maxilla and mandible and successful eruption of one of the transmigrated mandibular canines following orthodontic traction. Etiology of transmigration and its clinical considerations are also discussed.
