摘要:

牙完全脱位常发生于年轻恒牙,目前常用的治疗方法是牙再植术和夹板固定,但常出现根尖炎症、牙根外吸收及骨性粘连等不良预后,最终导致牙齿无法保留。本文报道的是1例8岁男性患儿撞伤致混合牙列的左右下颌中切牙完全脱位3 h,脱位牙牙根尚未发育完成,经牙再植术及弹性夹板固定后,随访观察15个月,维持在稳定的功能位置,未见根尖周炎症及骨性粘连等发生。

Abstract:

Tooth avulsion is one of the most serious case of all traumatic injuries, frequently found in the immature permanent teeth. The common treatment for avulsed permanent tooth is replantation and splint fixation. However it usually results in root inflammation, root absorption and ankylosis, eventually lead to extraction. The present report describes a 8-year-old boy with two immature mandibular central incisors avulsed three hours after the accident. Replantation was performed, and the teeth were splinted. Radiographic and clinical examinations were performed during 15 months follow-up. At present, the avulsed teeth have a favorable prognosis, and remained in a stable functional position and did not reveal root inflammation, root absorption and ankylosis.

Key words: Dental trauma, Avulsion, Immature permanent teeth, Replantation, Prognosis
