Intrusive luxation of permanent mature teeth is one of the most serious injuries to the periodontal ligament in dental traumatology. Various treatment approaches are currently practised. The treatment of choice for traumatically intruded teeth was to combine orthodontic repositioning and endodontic treatment. This case report describes the treatment of a 50-year-old male patient, with four completely intruded mature permanent maxillary incisors. Orthodontic extrusion was initiated 1 week after the trauma. After 10 days, the crowns of the teeth were exposed to start endodontic therapy. Nine weeks after the injury and 8 weeks after the beginning of orthodontic extrusion, the intruded incisors were back about to their original position before the displacement occurred. All treatment management as well as a follow-up 8 years after the trauma are described.
恒牙成熟牙的嵌入性脱位是牙外伤中对牙周膜最严重的损伤之一。目前有多种治疗方法。对于外伤性嵌入牙，首选的治疗方法是正畸复位与根管治疗相结合。本病例报告描述了一名50岁男性患者的治疗情况，该患者有四颗完全嵌入的上颌成熟恒牙切牙。外伤后1周开始进行正畸牵引。10天后，牙齿冠部暴露，开始进行根管治疗。受伤9周后，正畸牵引开始8周后，嵌入的切牙回到了移位前的大致原位。文中描述了所有的治疗管理以及外伤后8年的随访情况。
