Orthodontic cases requiring tooth extraction sometimes involve post-traumatic incisors. For adolescent cases in which trauma causes the maxillary unilateral incisors to be missing or have poor prognoses, it is worth considering these teeth as candidates for extraction, and this unusual approach is seldom reported in the literature. An adolescent patient with a missing maxillary left lateral incisor and an ankylosed maxillary left central incisor sought treatment for dental protrusion and crowding. An unusual orthodontic approach was used, which involved the extraction of the maxillary left central incisor and mandibular first premolars. After treatment, the maxillary right central incisor was successfully translocated across the midpalatal suture and transformed into the left central incisor. Additionally, well-aligned teeth and enhanced smile aesthetics were achieved, and the treatment outcomes remained stable throughout the follow-up period.
正畸拔牙病例有时涉及外伤性切牙。对于因外伤导致上颌侧切牙缺失或预后不佳的青少年病例,值得考虑将这些牙齿作为拔牙候选牙,这种不常见的方法在文献中很少报道。一位上颌左侧侧切牙缺失和上颌左侧中切牙骨粘连的青少年患者因牙齿前突和拥挤寻求治疗。采用了一种不寻常的正畸方法,涉及拔除上颌左侧中切牙和下颌第一前磨牙。治疗后,上颌右侧中切牙成功地穿过腭中缝并转化为左侧中切牙。此外,还获得了排列整齐的牙齿和改善的微笑美学效果,并且在随访期间治疗结果保持稳定。
