Oral-Maxillofacial Surgery and Orthodontics

Oral-Maxillofacial Surgery, Dentistry and Orthodontics

The Department of Oral-Maxillofacial Surgery and Orthodontics mainly provides medical care for patients with congenital or acquired abnormalities of the teeth and jaw such as maxillofacial deformities, maxillofacial trauma, and oral tumors; and other severe systemic diseases.

Medical services

A team of physicians, dentists, and speech therapists provide interdisciplinary treatments, such as oral, dental and maxillary surgery (oral-maxillofacial surgery) for oral inflammation and tumors; prosthetic treatments using artificial teeth and dental implants (prosthetic dental treatment) for deficient teeth and maxilla due to tumor and trauma; improvement of dental articulation in patients with significant maxillary deformation and control of jaw growth (orthodontics).

Diagnosis and treatment policy

At the first consultation, a doctor specializing in the treatment required for each patient is assigned to the case. This is followed by, if necessary, x-ray examination, blood tests, stomatognathic function test, tissue biopsy, and other examinations. The final treatment plan is determined through discussion based on these specialized test results.
