Pre-eruptive migration of a tooth across the midline is termed "transmigration". This condition has not been reported for teeth other than mandibular canines. Bilateral transmigration is extremely rare, and associated pathological lesions are also reported. The aim of this report is to present the first case of maxillary canine transmigration as well as additional cases of transmigrated mandibular canines, with special emphasis on their classification.
牙齿在萌出前越过中线的移动被称为“异位萌出”。除下颌尖牙外,这种情况在其他牙齿中尚未见报道。双侧异位萌出极为罕见,且也有相关病理损害的报道。本报告的目的是呈现首例上颌尖牙异位萌出病例以及额外的下颌尖牙异位萌出病例,并特别强调其分类。
