We report a case of a horizontal intra-alveolar root fracture between the middle and apical third of the upper right central incisor associated with an extrusive luxation of the coronal fragment, in a 24-year-old male patient. Twenty minutes after being accidentally hit by a metallic device, the patient's coronal portion was repositioned and splinted under local anesthesia. After that, we lost sight of the patient. One year later, the patient showed up. The splint was lost, the tooth showed physiological mobility and responded to pulp testing. Radiographs showed healing of the horizontal fracture and normal periodontal ligament.
我们报告了一例 24 岁男性患者右上中切牙近中-根尖三分之一水平向牙槽内骨折，伴冠部脱位。在被金属器械意外撞击 20 分钟后，患者在局部麻醉下复位并结扎了冠部。此后，我们与患者失去了联系。一年后，患者出现。结扎丝丢失，牙齿有生理性动度，对牙髓测试有反应。X 线片显示水平骨折愈合，牙周膜正常。
