摘　　要：牙外伤通常发生在前牙区,尤其是上前牙区。在恒牙外伤中,同一部位发生第二次损伤的概率很低,短时间内发生第二次损伤的概率更低。目前,尚无确切的文献报道。本文报道了1例罕见的半年内上前牙区发生2次牙外伤病例。治疗结束后,牙槽骨得到良好的改建,上前牙的功能和美观得到良好的恢复,为短期内同一区域发生两次牙外伤患者的诊疗提供了临床经验。Dental trauma usually occurs in the anterior tooth area,especially in the upper anterior tooth area.For permanent teeth,the probability of twice traumas at the same site is very low,not to say the second trauma happened within a short time.This paper reports a case of twice tooth traumas in the upper anterior region within 6 months.After treatment,the alveolar bone was well reconstructed,and the function and aesthetics of the upper anterior teeth were well restored,providing clinical experience for the diagnosis and treatment of patients with twice dental traumas in the same area within a short period.
