This case report describes the delayed endodontic and prosthetic treatment of two maxillary central incisors in a 16-year-old patient. Both teeth had been traumatized eight years previously. The examination revealed arrested root formation with wide open apices, periapical inflammation and inflammatory resorption. Endodontic treatment with calcium hydroxide led to formation of hard tissue barriers in both teeth so that definite obturation could be performed. One tooth was lost due to a deep crown-root-fracture and replaced by an intraosseous implant, whereas the other incisor was retained for nearly four years.
本病例报告描述了一名16岁患者上颌两颗中切牙的延迟牙髓治疗和修复治疗。两颗牙齿均在八年前受过外伤。检查发现牙根形成停滞，根尖孔敞开，根尖周炎和炎症性吸收。用氢氧化钙进行牙髓治疗后，两颗牙齿均形成了硬组织屏障，从而可以进行确切的根管充填。一颗牙齿因冠根深部折断而缺失，由骨内种植体替代，而另一颗中切牙保留了近四年。
