The department was founded by Professor Masaaki Kawamura in 1974.
Professor Yasunori Totsuka headed the department since 1992 till 2012.
Professor Kanchu Tei headed the department since 2012 till now.

We dedicate our efforts to providing the highest educational standards for dental students, as well as, offering the most comprehensive training programs for young clinicians to provide the best service for their communities. We provide postgraduate courses of both basic and clinical research nature.

1. Multidisciplinary approach for Cleft Lip and Palate patients.
2. Conservative treatment of ameloblastoma.
3. Functional and morphological orthognathic correction of jaw deformities.
4. Oral cancer (basic and clinical studies).
5. Arthroscopic and minimally invasive surgeries for Temporomandibular disorders (TMD).
6. Dysphagia in oral cancer patients (prediction and rehabilitation).
7. Dental implants and alveolar bone augmentation.

Our outpatient clinics receive more than 15,000 patients annually, of which 2,500 patients are initially diagnosed. Majority of patients suffer inflammations, temporomandibular disorders, impacted teeth, and a variety of cystic lesions and tumors. Minor oral surgeries are carried out on an outpatient basis in our Day-Surgery-Center. We provide specialized clinics and staff for patients with cleft lip and palate, jaw deformities, dental implant and malignant tumors.

About 600 patients are hospitalized annually, of which 350 patients receive surgical treatments under general anesthesia. Those patients are mainly oncology, orofacial deformity, and dental implant patients.

“Team Approach” is our distinctive strategy as we aim to provide our patients supreme services. Joined conferences are routinely held among Oral & Maxillofacial Surgeons, Orthodontists, Prosthodontics, Speech Therapists and Rehabilitation Medicine Specialists; in brainstorming sessions for diagnosing, planning and following patients suffering congenital jaw deformities and malignancies.

Oral and Maxillofacial Surgery Department starts its undergraduate educational role in the 4th year through clinical lectures focusing on:
・ Cleft lip and palate
・ Jaw deformities
・ Temporomandibular disorders
・ Cysts
・ Tumors
・ Implants
・ Surgical techniques
Undergraduates of the 5th and 6th (final) years enjoy a more in-depth education/training through 6 weeks of chair/bedside courses in both our outpatient and inpatient clinics.

We provide a one-year residency course for postgraduates, during which young doctors rotate around all departments of our school to enrich their knowledge as general practitioners.Doctoral courses are available for young doctors who have completed their residency courses. Doctoral courses include intensive research for the main course of study which is either basic or clinical research. Clinical research is actively pursued by our residents as they work under close supervision by our staff members. Doctoral courses enrich and develop participant’s research/clinical planning, case report preparation and presentation, as well as their writing skills. Basic research targets new findings in various research fields that could help providing better treatments for existing diseases or anatomical phenomena, on both cellular and molecular levels. Basic researches are commenced in collaboration with other departments of the Graduate School of Dental Medicine.
