Orthodontic Treatment, Including Transplanted Teeth and Dento-Alveolar Osteotomy, for Dental Ankylosis after Multidisciplinary Treatment for Rhabdomyosacroma of the Cheek: A Case Report and Review

Multidisciplinary treatment for head and neck malignant tumors is often performed in children and adolescents. This treatment strategy may induce dental morphological aberrations and missing teeth, resulting in leading to problems with occlusions. A 14year-old male underwent multidisciplinary treatment for rhabdomyosarcoma of his right cheek when he was three years old. He claimed a serious malocclusion. The hopeless teeth were extracted. Simultaneously, the bilateral lower first premolars were auto transplanted to the upper right canine and first premolar regions. Total orthodontic treatment was initiated six months after the surgery. Subsequently, a segmental osteotomy was performed because of dental ankylosis of the right upper central incisor. Finally, a good occlusion was created. Orthodontic treatment that includes the transplanted tooth after healing can create an ideal dental arch and good occlusion. If dental ankylosis is determined, a dentoalveolar osteotomy should be performed to create a good occlusion.
