BACKGROUND
Double teeth are dental anomalies that can lead to aesthetic and orthodontic problems.
CASE PRESENTATION
This report discusses two cases involving the multidisciplinary management of permanent maxillary left lateral incisors fused with a supernumerary tooth in two girls aged 9 and 10. Following intraoral and radiographic examinations, one was diagnosed with fusion, and the other was diagnosed with concrescence. The crown of the fused incisor was separated using a burs and extracted intraorally. The concrescent incisor was separated along its length using a laser and intentionally replanted extraorally. After a 6-year follow-up, no pathological signs were observed in the fused incisor. However, after an 11-year follow-up, external resorption was observed in the concrescent incisor.
CONCLUSIONS
Both incisors remained asymptomatic throughout the observation period. This case report highlights two different and effective methods employed to preserve the natural function, form, and aesthetics of double incisors.
背景
双牙是一种导致美观和正畸问题的牙齿异常。
病例介绍
本报告讨论了两例 9 岁和 10 岁女孩的多学科治疗方案，她们的上颌左侧恒侧切牙与额外牙融合。经过口腔内和影像学检查，其中一个被诊断为融合，另一个被诊断为联合。融合侧切牙的牙冠用金钢砂车针分离后从口内取出，联合侧切牙用激光沿其长度分离并体外再植。6 年随访期内，融合侧切牙未观察到病理性改变。然而，11 年随访期后，联合侧切牙出现了外部吸收。
结论
两颗切牙在整个观察期间均无症状。本病例报告强调了两种不同且有效的方法，用于保留双切牙的自然功能、形态和美观。
