The case presented is a report of a healthy 11-year-old boy, who fell down and traumatized his four maxillary incisors. Both central incisors were deeply intruded with concomitant uncomplicated crown fractures, and both lateral incisors suffered concussion. The intruded teeth were repositioned using a removable orthodontic appliance and were endodontically treated 3 weeks after trauma. Tooth 11 became ankylosed 3 months post trauma, and tooth 21 was extruded to its original position after 5 months. Five months post-trauma, teeth 12 and 22 underwent necrosis and were endodontically treated. In addition, tooth 22 presented an external inflammatory root resorption that was arrested by calcium hydroxide paste after 3 months. A crown-lengthening procedure was performed on tooth 11 10 months post-trauma, exposing the clinical crown to a better condition for restoration. All 4 incisors were restored with a composite material, and the incisal edges of the central incisors were shaped at the same level. Two months after the crown lengthening procedure, spontaneous eruption occurred on tooth 11, that had been ankylosed. The restored incisal edge of tooth 11 was reduced to the same level of tooth 21. The patient is under periodical examination till a definitive orthodontic treatment can be performed.
所呈现的病例报告了一名健康的11岁男孩，他摔倒后上颌四颗切牙受到创伤。两颗中切牙均深深嵌入并伴有无并发症的冠折，两颗侧切牙遭受震荡伤。嵌入的牙齿使用可摘正畸矫治器进行复位，并在创伤后3周进行根管治疗。11号牙在创伤后3个月发生粘连，21号牙在5个月后自行萌出到原来位置。创伤后5个月，12号牙和22号牙发生坏死并接受根管治疗。此外，22号牙出现外部炎性牙根吸收，3个月后用氢氧化钙糊剂阻止了吸收。创伤后10个月对11号牙进行了冠延长术，使临床冠暴露于更好的修复状态。所有四颗切牙均用复合材料修复，中切牙的切缘修整到同一水平。冠延长术后两个月，已发生粘连的11号牙出现自发萌出。11号牙修复后的切缘降低到与21号牙相同水平。患者正在接受定期检查，直到可以进行确定性正畸治疗。
