This case report describes a Class I crowded malocclusion with an ankylosed maxillary central incisor that was in infraocclusion and labially displaced. The patient had wide maxillary teeth, and the option of extracting the maxillary central incisors followed by space closure, with lateral incisors substituting for the central incisors, was chosen.
本病例报告描述了一例Ⅰ类牙列拥挤错颌畸形，伴有一颗上颌中切牙粘连，处于低位咬合且唇向移位。患者上颌牙齿较宽，选择拔除上颌中切牙，随后关闭间隙，由侧切牙替代中切牙。
