This case report describes the orthodontic treatment of a 9-year-old girl with skeletal Cl III malocclusion, an impacted maxillary right central incisor, and ipsilaterally displaced canine. The impacted maxillary central incisor was inverted and the root was crooked. After the maxillary right central incisor was extracted, the ipsilateral canine spontaneously moved toward the extracted incisor position. However, eruption did not occur, so we began the traction of the maxillary right canine after setting Nance's holding arch appliance for reinforced anchorage. The maxillary right canine was aligned the position of a central incisor after creating sufficient space using a multibracket appliance. For the skeletal problems, a maxillary protractive appliance was applied to improve the intermaxillary relationship. The treatment period employing the multibracket appliance was: 11 months for acquiring the canine space, one year and four months for traction of the canine, and two years and 11 months for full alignment of the maxillary and mandibular teeth, with a total of 5 years and 2 months. As a result, satisfactory dental aesthetics were achieved by adjusting the shape of the crown of the canine as well as realizing stable occlusion with a sufficient function.
