A 10-year-old male presented with a mobile and fractured maxillary right central incisor following dental trauma. Clinical and radiographic examinations revealed a chisel-type crown-root fracture with supragingival labial and subgingival palatal extensions. A direct crown reattachment was planned, emphasizing biological width preservation. After removing the coronal fragment, endodontic treatment was performed using a rotary file system and was obturated with a bioceramic sealer. A fiber post was selected and integrated into the fractured fragment, which was reattached using resin cement. Additionally, a gingivectomy was performed to enhance margin visibility and restore biological width. The adjacent left central incisor was treated for an uncomplicated crown fracture using follow-up evaluations over 12 months revealed stable fragment reattachment, good periodontal health, and restored aesthetics and function. A custom mouthguard was provided to prevent future trauma. This case highlights the efficacy of a multidisciplinary approach combining endodontic, restorative, and periodontal techniques for managing crown-root fractures, achieving favorable long-term outcomes in pediatric patients.
一名10岁男性在牙齿外伤后出现上颌右侧中切牙松动和骨折。临床和影像学检查显示为凿形冠根折，唇侧龈上及腭侧龈下延伸。计划进行直接冠重新附着，强调保留生物学宽度。去除冠部碎片后，使用旋转锉系统进行根管治疗，并用生物陶瓷封闭剂进行根管充填。选择一根纤维桩并将其整合到骨折碎片中，然后用树脂水门汀重新附着。此外，进行牙龈切除术以提高边缘可见度并恢复生物学宽度。对相邻的左侧中切牙进行了简单冠折治疗，经过12个月的随访评估，显示碎片重新附着稳定、牙周健康良好、美观和功能得以恢复。提供了定制的口腔防护器以防止未来的创伤。该病例突出了结合根管治疗、修复和牙周技术的多学科方法在处理冠根折方面的有效性，在儿科患者中取得了良好的长期效果。
