This report presents a case of intrusive luxation of immature maxillary central incisors with concomitant uncomplicated crown fractures in an 8-year-old boy. The intruded teeth with open apices were repositioned with surgical extrusion and endodontically treated through use of calcium hydroxide paste. Six months after initiation of apexification, definitive apical stops had formed. The canals were then permanently obturated, and the crowns were restored with composite resin. Clinical and radiographic examination 24 months after the surgical extrusion revealed satisfactory apical healing and healthy supporting tissues.
本报告介绍了一名8岁男孩上颌未成熟中切牙侵入性脱位并伴有单纯性冠折的病例。对根尖开放的嵌入牙进行手术牵引复位，并使用氢氧化钙糊剂进行根管治疗。根尖诱导成形开始6个月后，形成了明确的根尖止点。然后对根管进行永久性充填，并用复合树脂修复牙冠。手术牵引24个月后的临床和影像学检查显示根尖愈合良好，支持组织健康。
