With the growth of the aged population, untreated elderly patients who have malocclusion with prognathism will increase. When a patient with prognathism becomes edentulous, we often experience, during treatment, complete dentures not being stable and the patient is not satisfied with the form of the dentures because the relative position of the maxilla and mandible is skeletal Class III. We report a case of mandibular prognathism with edentulous maxilla by orthognathic treatment. The patient is a 58-year-old woman. Her complaint is that because the full maxillary denture is not stable, she cannot bite right and where the mandibular protrusion is. The diagnosis is a mandibular protrusion with edentulous maxilla and partially edentulous mandible (7-4). We made a full maxillary denture and sagittal split ramus osteotomy (SSRO) was performed. After orthognathic surgery, the position of the maxilla and mandible were improved. Thereafter, we made a definitive prosthesis. As the dentures were stable and the mandibular protrusion had improved, the patient was satisfied.
