The maxillary central incisor can be lost due to dental injury, and it can be treated with orthodontic space closure. This case report presents the orthodontic treatment of a 22-year-old male patient who lost the maxillary right central incisor due to trauma. The maxillary left central incisor was moved across the midline to replace the missing right central incisor. The left lateral incisor was moved to replace the left central incisor, and the other maxillary left teeth were moved mesially to achieve a fully interdigitated Class II molar relationship. The left central and lateral incisors were reshaped as the right and left central incisors with porcelain crowns, and the final results were satisfactory in occlusion and esthetics. The effects of this alternative treatment on the midpalatal suture, nasopalatine foramen, labial frenum, and root apex of the central incisor are described.
