In the present case, decoronation and root submergence of a necrotic maxillary central incisor were performed for a 13-year-old girl. The root canal was filled with mineral trioxide aggregate (MTA), which was covered with resin-modified glass ionomer. Apexification with MTA was performed for her other maxillary central incisor, and the edentulous region was restored using a fiber-reinforced composite bridge. Long-term follow-up indicated that decoronation might be a viable option to maintain the alveolar bone.
在本病例中，为一名13岁女孩对一颗坏死的上颌中切牙进行了去冠和牙根埋没术。根管内充填了三氧化矿物凝聚体（MTA），并覆盖了树脂改性玻璃离子水门汀。对她的另一颗上颌中切牙采用MTA进行根尖诱导成形术，并用纤维增强复合桥修复无牙区。长期随访表明，去冠术可能是维持牙槽骨的一种可行选择。
