Tooth autotransplantation is the placement of an impacted or erupted tooth into an extraction site or surgically prepared dental socket within the same individual. This procedure may become a new treatment alternative, because of its osteogenetic potential and its ability to promote regeneration of alveolar processes. The present study reports the case of a 10-year-old girl whose maxillary central incisor was ankylosed as the result of an injury, and who underwent tooth autotransplantation and orthodontic treatment for the functional and aesthetic recovery of the maxillary central incisor. The transplanted tooth showed satisfactory alveolar bone recovery, and orthodontic tooth movement. No complications occurred. We chose to report this case because it illustrates the autotransplantation of a premolar in a child scheduled for orthodontic treatment, including tooth extraction. The procedure showed good prognosis in terms of the recovery of an anterior tooth affected by an injury
