Abstract: Eruption disturbances are a significant challenge in orthodontic treatment. This case report presents a 9-year-old female patient with tooth transposition and impaction in the maxilla treated in two phases. The patient exhibited a Class I malocclusion, posterior crossbite, maxillary midline deviation, and clinical absence of the right maxillary central incisor and canine. Panoramic radiograph revealed that the right central incisor was impacted, and the right canine was transposed with the adjacent lateral incisor. Treatment involved maxillary expansion followed by orthodontic traction of the canine and central incisor. Comprehensive orthodontic treatment was carried out while maintaining the canine-lateral incisor transposition. An adequate occlusion was achieved, improving both smile esthetics and quality of life.
