This case report examines the effectiveness of extraoral treatment of a traumatized maxillary central incisor with a transverse intra-alveolar root fracture. Both the coronal and root segments were extracted after anesthetic injection. After treatment of the pulpal cavity, the segments were synthesized with a composite resin and a canal reamer. The extracted tooth was replanted into the original socket. This method is an alternative treatment for transverse intra-alveolar root fracture, which is presently an indication for dental extraction in almost all cases.
本病例报告探讨了对上颌中切牙遭受创伤并伴有牙槽内横向根折进行口外治疗的有效性。在注射麻醉剂后，将冠部和根部断段均予以拔除。对髓腔进行处理后，使用复合树脂和根管扩孔钻将断段进行了拼接。将拔除的牙齿再植回原牙槽窝。这种方法是牙槽内横向根折的一种替代治疗方法，而目前在几乎所有病例中，牙槽内横向根折都被视为拔牙指征。
