Abstract

We decided among extraction, orthodontic traction and autotransplantation such as direction and position of unerupted tooth, degree of developing root apex, eruption space, being of supernumerary tooth or odontoma or cyst when tooth impacted. Autotransplantation is considered when orthodontic traction is unrealistic or when tooth movement can absorb root of neighbor tooth. The prognosis for successful autotransplantation is dependent on a number of factors such as root development, surgical technique, patient's age, endodontic treatment, time and type of splinting, preservation of periodontal ligament and storage medium. Especially when severe osseous defect is being, bone graft considered for reducing of mobility and for assisting recovery. In all cases, chief complaint is unerupted tooth and various causing factors were supernumerary, odontoma, ectopia and so on. Before autotransplantation, space regaining was done if needed and demineralized freezed dried bone and autogenous bone graft was done when there is severe osseous defect by extraction of supernumerary tooth or odontoma. Splinting was removed after 2-3weeks At 3-4weeks after autotransplantation, endodontic treatment was decided. At follow up check, normal recovery was done and there was no inflammatory or replacement root resorption in periapical radiograph.
