Intrusive luxation of permanent teeth is a relatively uncommon type of injury to the periodontal ligament. However, it is one of the most severe types of dentoalveolar trauma. By definition, intrusive luxation consists of the axial displacement of the tooth into the alveolar bone, accompanied by comminution or fracture of the alveolar bone. Here we report the treatment management of a traumatically intruded immature permanent central incisor by surgical repositioning undertaken in a 10-year-old child with rheumatic fever 10 days after sustaining a severe dentoalveolar trauma. The intraoral examination showed the complete intrusion of the permanent maxillary right central incisor and the radiographic examination revealed incomplete root formation. Prophylactic antibiotic therapy was prescribed and the intruded tooth was surgically repositioned and endodontically treated thereafter. The postoperative course was uneventful, with both clinically and radiographically sound conditions of the repositioned tooth up to 3 years and 2 months of follow-up. These outcomes suggest that surgical repositioning combined with proper antibiotic prophylaxis and adequate root canal therapy may be an effective treatment option in cases of severe intrusive luxations of permanent teeth with systemic involvement.
恒牙嵌入性脱位是一种相对少见的牙周膜损伤类型。然而，它是牙槽突创伤中最严重的类型之一。根据定义，嵌入性脱位是指牙齿轴向移位进入牙槽骨，并伴有牙槽骨粉碎或骨折。在此，我们报告一名10岁患风湿热的儿童在遭受严重牙槽突创伤10天后，通过手术复位治疗外伤性嵌入的未成熟恒中切牙的病例。口腔检查显示上颌右侧恒中切牙完全嵌入，影像学检查显示牙根未完全形成。给予预防性抗生素治疗，随后对嵌入的牙齿进行手术复位并进行根管治疗。术后过程顺利，在长达3年2个月的随访中，复位牙齿的临床和影像学状况均良好。这些结果表明，对于伴有全身并发症的恒牙严重嵌入性脱位病例，手术复位联合适当的抗生素预防和充分的根管治疗可能是一种有效的治疗选择。
