To describe the orthodontic management of root dilaceration of an impacted maxillary tooth following trauma to its deciduous predecessors, to show the clinical management of root dilaceration of a maxillary central incisor and describe how the dilacerated tooth was successfully moved into alignment in a young patient with a proper multidisciplinary approach, using the simple and effective straightwire technique.
After surgical exposure and orthodontic traction, the impacted dilacerated tooth was brought to alignment in the arch. The patient's chewing and speech function, and aesthetics were restored. The radiograph shows that the root is finally straight and relatively well developed. This approach avoids extraction and prosthetic rehabilitation of the dilacerated tooth.
描述乳牙期上颌牙外伤后继发的埋伏牙牙根弯曲畸形的正畸治疗方法,展示上颌中切牙牙根弯曲畸形的临床处理过程,并阐述如何采用简单有效的直丝弓技术,通过多学科协作的方式成功将弯曲畸形牙排齐到年轻患者牙弓中。
经过外科暴露和正畸牵引后,埋伏的弯曲畸形牙被排齐到牙弓中。患者的咀嚼、言语功能及美观得以恢复。X线片显示牙根最终变直且发育相对良好。该方法避免了弯曲畸形牙的拔除及修复治疗。
