BACKGROUND – Ankylosis of traumatized teeth is a common phenomenon after trauma and is caused by destruction of the periodontal ligament with resorption and bone healing from the alveolar bone afterwards. Ankylosis in growing individuals will often result in compromised aesthetics, resulting
in a complex orthodontic and prosthetic situation. Different interventions have been proposed for treating ankylosed permanent front teeth in infraocclusion. The choice of treatment depends on the severity of infra-occlusion, the degree of resorption, patient age and expectations.
CASE STUDY – A 13-year-old girl with an ankylosed left maxillary central incisor was referred to the Department of Oral and Maxillofacial Surgery, Hospital of Southwest Denmark, University Hospital of South Denmark. The left maxillary central incisor was positioned 4 mm apically with healthy periodontal status. Radiographic examination showed external resorption and apical radiolucency at the actual tooth. The treatment of the ankylosed maxillary central incisor was
done with a segmental osteotomy with autogenous bone graft for stabilisation.
CONCLUSION – Segmental osteotomy with autogenous bone grafting is a single-stage surgery, which should be performed at the earliest, at the end of the skeletal growth. It is a simple and predictable surgical procedure in the treatment of ankylosed maxillary incisor in achieving acceptable aesthetics and
function. At the same time the procedure provides better hardand soft tissue conditions for later implant based prosthetic rehabilitation.
