Dentoalveolar trauma is frequently encountered by dental practitioners. In some instances, saving a child's traumatized permanent teeth can create difficulties for the child, the parents and the dentist. Reattachment of a crown fragment is a conservative treatment that should be considered for crown fractures of anterior teeth. This case describes the clinical reattachment of an original tooth fragment. A 10-year-old male presented at the Department of Pediatric Dentistry with a complex crown fracture of the left maxillary central incisor 1 day after the trauma occurred. Following endodontic treatment, a glass-fibre-reinforced composite root canal post (FRC Postec; Ivoclar Vivadent AG, Schaan, Liechtenstein) was inserted to increase retention and distribute stress along the root. The dental restoration was completed using the original fragment and a dual-cured resin composite (Variolink II; Ivoclar Vivadent AG). Clinical and radiographic examinations at 1-year recall showed the glass-fibre-reinforced composite root canal post and restoration to be in place, indicating the success of the treatment in maintaining the fractured tooth. Thus, we conclude that reattachment of a tooth fragment using a dual-cured resin composite and a glass-fibre-reinforced composite root canal post is an alternative method for the rehabilitation of fractured teeth that offers satisfactory aesthetic and functional outcomes.
牙牙槽创伤在牙科医生的临床工作中经常遇到。在某些情况下，保留儿童受创伤的恒牙可能会给儿童、家长和牙医带来困难。冠碎片再附着是一种保守治疗方法，对于前牙冠折应予以考虑。本病例描述了原牙碎片的临床再附着情况。一名10岁男性在创伤发生1天后因左上颌中切牙复杂冠折就诊于儿童牙科。根管治疗后，插入一根玻璃纤维增强复合根管桩（FRC Postec；义获嘉伟瓦登特公司，沙恩，列支敦士登）以增加固位力并沿牙根分散应力。使用原碎片和双固化树脂复合材料（Variolink II；义获嘉伟瓦登特公司）完成牙齿修复。1年复查时的临床和影像学检查显示玻璃纤维增强复合根管桩及修复体位置良好，表明该治疗在保留折裂牙方面取得成功。因此，我们得出结论，使用双固化树脂复合材料和玻璃纤维增强复合根管桩进行牙碎片再附着是折裂牙修复的一种替代方法，可提供令人满意的美学和功能效果。
