The Section of Oral Surgery takes charge of the education, research and clinics involved in any bone-related diseases occurring in the jaw. The specialty of this section covers deformity, malformation, fracture and inflammation in the jaw and TMJ.
1. Orthoganthic Surgery
Approximately 100 cases of orthognatic surgery are performed every year to treat mandibular prognathism, laterognathism, maxilla retroganthism and open bite. Two jaws surgery consisting of sagittal split ramus osteotomy and Le Fort I osteotomy is our main surgical technique.
2. TMJ disease
Various symptoms, such as pain, clicking sound and limitation of mouth opening, occur in the patients with temporomandibular disorder (TMD). The patients are usually treated with physiotherapy such as jaw opening rehabilitation, splint therapy and lavage. TMJ surgery is applied to condylar tumor, TMJ ankylosis and TMJ luxation.
3. Trauma
Jaw fracture and/or tooth luxation often occur because of fall, quarrel, sports and traffic accident. Fracture of mandible and maxilla is surgically treated paying attention to the recovery of occlusion and jaw function.
4. Preprosthetic Surgery
Bone augmentation at alveolar ridge is often required for the stabilization of prosthetics such as denture and dental implant. Bone graft technique is applied to atrophic jaw and sinus lift.
5. Inflammatory jaw disease
A variety of inflammatory jaw diseases such as bisphosphonate-related osteonecrosis of the jaw (BRONJ) are treated.
Research
1. Clinical research on nerve injury related to orthognathic surgery.
2. Cell biological study on bisphosphonate-related osteonecrosis of the jaw.
3. Image analysis for predicting the change of facial view due to orthognathic surgery.
4. Clinical research on the sports-related injury and oral trauma of aged person.
5. Basic research on NF-kB in osteoclast and osteoblast.
