Trauma resulting in crown-root fracture is one of the most challenging fracture types. However, biologic width involvement should be carefully evaluated. Reattachment of tooth fragment to a fractured tooth remains as the treatment of choice because of its simplicity, natural esthetics, and conservation of tooth structure. The reattachment procedure using composite resin should be considered if the subgingival fracture can be exposed to provide isolation. This report presents a case of complicated crown-root fracture of permanent maxillay left central incisor, involving the biologic width in a 10-year-old girl. The traumatized tooth was treated endodontically. Access to the subgingival margins was gained by orthodontic extrusion followed by gingivectomy. The fractured fragment was reattached using bonding system and composite resin.
导致冠根折的创伤是最具挑战性的骨折类型之一。然而，应仔细评估生物学宽度的累及情况。由于其操作简单、自然美观且能保留牙体结构，将牙碎片重新附着于折断牙上仍是首选治疗方法。如果能暴露龈下骨折以提供隔离，则应考虑使用复合树脂进行重新附着手术。本报告介绍了一例10岁女孩上颌左侧恒中切牙复杂冠根折的病例，该骨折累及生物学宽度。对受伤牙齿进行了根管治疗。通过正畸牵引随后行牙龈切除术来暴露龈下边缘。使用粘结系统和复合树脂将折断碎片重新附着。
