摘要/Abstract

摘要：

牙外伤是口腔临床工作中较为常见的急症之一，发病率高，上颌中切牙最易受累。本文报告1例17岁女性患者，因外伤导致11、21牙完全脱位，21牙脱位后遗失，11牙因唇侧牙槽骨壁缺如导致再植术预后差，因此将11牙体外根管治疗后再植于条件较好的21牙牙槽窝内，并行弹性夹板固定。随访观察20个月，发现患牙维持在稳定的功能位置，未见根尖周炎症及骨性粘连发生，延期行11牙位种植修复，最终取得良好的治疗效果。这或在未来牙再植的临床实践中成为新的思路启发点与参考依据。

Abstract:

Dental trauma is one of the relatively common emergencies in clinical dental practice, with a high incidence rate, and the maxillary central incisors are the most frequently affected. This article reports a case of a 17-year-old female patient who suffered traumatic complete avulsion of teeth 11 and 21, with tooth 21 lost after avulsion. The prognosis for replantation was poor due to the absence of the buccal alveolar bone wall of tooth 11. Therefore, tooth 11 was treated with extracorporeal root canal therapy and then replanted into the alveolar socket of tooth 21, which had better conditions, followed by elastic splint fixation. After 20 months of follow-up observation, the affected tooth maintained a stable functional position, with no periapical inflammation or ankylosis observed. Subsequently, delayed implant restoration at the site of tooth 11 was performed, ultimately achieving a favorable treatment outcome. This case may provide new insights and references for future clinical practices in tooth replantation.

Key words: dental trauma, tooth avulsion, heterotopic replantation, implant restoration
