Introduction
Lefort I osteotomy is frequently used in the reconstruction of patients with Class III occlusion caused by insufficiency of the maxillary bone. In cases where bone augmentation is required for the rehabilitation of edentulous alveolar ridges with implant treatment, the use of autogenous grafts is considered the gold standard. In cases where the required amount of bone is too much, iliac bone graft is one of the first preferred areas.
Case Report
In the radiographic and clinical examination of the patient who applied to our department for implant treatment, it was decided to extract the teeth with luxation and bone loss. Maxillary advancement was planned because the patient was in class III occlusion and the patient did not want to use a removable prosthesis. Following Lefort I osteotomy, the maxilla was moved 6mm forward. After orthognathic surgery, bone augmentation with iliac graft was planned, since it was determined that there was not enough bone width for implant treatment in the region between the mandible and premolars in the tomography images. Implant treatment of the patient was completed 4 months after the iliac grafting.
Conclusion
In patients with skeletal malocclusion and insufficient bone volume, it may be necessary to apply combined treatments to achieve reconstruction. In difficult cases, success can be achieved with the right treatment planning.
