A case of an 8-year-old boy who met with a road traffic accident causing trauma to the body and face and extrusion of the upper central incisors is reported. Laceration, oedema and limited mouth opening indicated the use of general anesthesia. During intubation the right central was avulsed accidentally and the left central further luxated and rotated. The avulsed central was reimplanted and the other one derotated and stabilised with orthodontic wire and brackets. Twelve weeks later the patients teeth were firm, immobile, radiographically normal and responded positively to vitality test.
报告了一例8岁男孩,他遭遇道路交通事故,身体和面部受到创伤,上颌中切牙被挤出。撕裂伤、水肿和张口受限表明需要使用全身麻醉。插管过程中,右上中切牙意外脱出,左上中切牙进一步脱位并旋转。脱出的中切牙被再植,另一颗牙通过正畸钢丝和托槽进行了复位和固定。12周后,患者的牙齿稳固、无松动,影像学检查正常,活力测试呈阳性反应。
