Tooth number abnormalities may occur under the influence of genetic or environmental factors which intervene in the tooth formation stages (induction and proliferation), most commonly the permanent dentition being affected. The result is the appearance of dental anomalies with numerical deficiency (hypodontia, anodontia), or with dental excess (hyperodontia, over-teeth). In this paper we report a case of a 15-year-old boy with associated abnormalities of permanent dentition: mesiodens and palatal impacted cuspid at the maxillary dental arch and incisor anodontia at the mandibular dental arch. Orthodontic treatment aimed at resolving maxillary dental crowding, obtaining dental alignment, a stable and functional occlusal relationship and a satisfactory smile for the patient.
牙齿数目异常可能在影响牙齿形成阶段（诱导和增殖）的遗传或环境因素作用下发生，最常受影响的是恒牙列。结果是出现牙齿数目不足（缺牙症、无牙症）或牙齿过多（多生牙、额外牙）的牙齿异常情况。在本文中，我们报告了一例15岁男孩伴有恒牙列相关异常的病例：上颌牙弓有正中多生牙和腭侧埋伏尖牙，下颌牙弓有切牙无牙症。正畸治疗旨在解决上颌牙列拥挤问题，实现牙齿排列整齐、稳定且功能良好的咬合关系，并为患者打造令人满意的笑容。
