Our Research

◎ Clinical Research on Diagnosis and Treatment of Jaw Deformity
Jaw deformity is an aesthetic disfigurement caused by abnormalities in the size, shape, and position of the maxilla, mandible, or both as well as abnormalities in the upper and lower jaw relationships, resulting in abnormalities in maxillofacial morphology and occlusion. Jaw deformity is difficult to treat with regular orthodontic treatment; instead, it requires orthognathic surgery and orthodontic treatment. We are conducting research on maxillofacial morphology and oral function to improve treatment outcomes. For research of morphology, we use standard X-ray photo analysis, 3D computed tomography image analysis, and digital and charge-coupled device cameras to analyze the 3D maxillofacial morphology before and after surgery. We also evaluate changes in facial appearance before and after surgery. For research of function, we use equipment to quantitatively evaluate and analyze occlusal and masticatory function before and after surgery.

◎ Psychological Research of Patients with Jaw Deformity and Cleft Lip and Palate
Patients with jaw deformity and cleft lip and palate are susceptible to loss of self-confidence, decreased social adjustment, and psychological disorders due to jaw, lip, and nose deformities. Orthognathic surgery and lip/nose correction surgery reportedly have a positive impact on these patients’ psychological well-being.
We conduct multiple psychological tests on patients with jaw deformity and cleft lip and palate to understand their psychological characteristics. Our goal is to elucidate how these characteristics change and to establish a treatment system that can provide better psychological support tailored to each individual patient.

◎ Basic and Clinical Research on Diagnosis and Treatment of Head and Neck Cancer
The treatment outcomes for patients with oral cancer are improving, but those for patients with advanced cancer are still poor. The major factors associated with poor treatment outcomes are local and cervical recurrence and distant metastasis. To solve these problems, our oncology research group conducts clinical and basic research on oral cancer diagnosis and treatment, oral cancer invasion, and metastasis.

◎ Research on Bone Regenerative Medicine
In the maxillofacial region, jawbone defects caused by tumor removal surgery or trauma not only directly lead to functional impairment, but they also affect cosmesis and significantly reduce quality of life. In our department, we are conducting research on stem cell-based bone regeneration therapy and experiments focused on developing more effective bone regeneration therapy at an earlier stage using rat calvarial bone defect models and mandibular condyle models.
