抄録

This study showed a case of occlusal and esthetic reconstruction using techniques of sagittal split ramus osteotomy (SSRO), sinus lifting procedure, periodontal treatment and implant restoration for a patient suffering from mandibular protrusion, missing molar teeth, and periodontal disease.
The patient was a 47-year-old female. Her chief complaint was disturbance of masticating. She had mandibular protrusion with asymmetry. She had periodontal disease and her molar teeth were missing. Panorama X-ray showed insufficient alveolar bone height of the maxilla for implant placement.
First of all, SSRO and sinus lifting procedure on the right side were performed under general anesthesia on Nov.17, 1995.
Mandibular bone was used as augmentation material in the sinus lifting procedure,and implants were placed in 64 region simultaneously. Seven months after the first surgery, the sinus lifting procedure using iliac bone was performed on the left side and implants were placed in 67 and 65 region. Final restoration was performed 6 months after the second surgery.
This case has been followed up for 2 years 9 months. Functionally and esthetically, the patient has been satisfied with the restoration, and periodontal parameters for implants have been stable.
