Intraosseous migration of impacted teeth across the midline to the opposite side of the jaw is a rare dental anomaly of unknown etiology. Transmigration of an impacted mandibular canine through the symphysis to the contralateral side of the arch has been documented. Transmigration of an impacted maxillary canine across the midpalatal suture to the opposite side of the maxilla has not been previously observed and is reported here for the first time.
阻生牙经骨内穿过中线迁移至颌骨对侧是一种病因不明的罕见牙齿异常。已有文献记载，阻生下颌尖牙经联合部迁移至牙弓对侧。上颌阻生尖牙经腭中缝迁移至上颌对侧此前未见报道，本文首次予以报告。
