Dentistry and Oral Surgery
Overview of the department
We are responsible for the treatment of patients with diseases of the jaw/oral cavity, such as maxillary/oral tumors, cysts, maxillofacial trauma, jaw deformities, inflammatory diseases, and impacted teeth. General dental treatment is provided only for persons who have medical referral letters.
Consultation system/therapeutic strategies
In the Department of Dentistry and Oral Surgery, the diagnosis and treatment of various diseases in the maxillary/oral areas, such as tumors in the oral area, cysts, trauma, inflammation, temporomandibular joint diseases, jaw deformities, and impacted wisdom tooth, are performed under guidance by instructors and specialists in oral surgery. Furthermore, advanced, safe, dental/oral surgical care is provided in cooperation with regional hospitals.
Fields of expertise
Jaw/alveolar ridge and masticatory function reconstruction
Autologous bone transplantation to the jaw before dental implant treatment is performed. In patients with a low bone height of the jaw, lumbar or oral jaw bones are collected, and transplanted to the insufficient site of insufficiency, facilitating implant treatment.
Concerning surgery for jaw deformities, team practice is conducted in cooperation with specialists in orthodontics. In orthodontic treatment, surgery is performed under general anesthesia for inpatients whose bite has markedly deviated and recovery is difficult. The jaw is cut through the oral cavity, and then fixed to achieve a normal bite. After surgery, postoperative orthodontic treatment is necessary in some cases to avoid a relapse to the preoperative state. In some patients, it is also possible to correct the positioning of teeth by inserting an implant. In such cases, this procedure is not covered by health insurance. Please consult us.
Advanced medical practice
Jaw tissue regeneration therapy
To minimize surgical invasiveness related to jaw bone transplantation, jaw tissue regeneration therapy with platelets existing in blood, myelocytes, or artificial bones is conducted.
Three-dimensional surgical simulation
Using three-dimensional images/jaw models, surgical simulation is performed. Based on this, safe and accurate surgery can be performed.
