Case reports have described displacement and migration of teeth in the upper and lower dental arches, but migration of a tooth across the mandibular midline is rare. The authors describe an extremely rare case of bilateral transmigration of impacted permanent canines across the midline of the mandible.
病例报告描述了上下牙弓中牙齿的移位和迁移，但牙齿穿过下颌中线的迁移很少见。作者描述了一例极其罕见的双侧阻生恒尖牙穿过下颌中线的迁移病例。
