Innovative Liaison DentistryCo-Creative Dentistry

Our major researches are focus on translational research and regulatory science based on interdisciplinary research, industry-government-academia collaboration research with a view to developing human resources who can take a broad and interdisciplinary overview of oral science through integrated knowledge education.

Specifically, through interdisciplinary research, we have developed advanced medical materials such as nickel-free shape memory alloys, bioabsorbable metallic glasses, and visible light-responsive titanium oxide, and have applied them to various innovative medical devices and materials. In addition, in collaboration with regulatory authorities such as the Pharmaceuticals and Medical Devices Agency (PMDA), we are also engaged in research on regulatory science, such as the formulation of international and domestic guidelines for various medical devices and materials.

Our division operates the "Division of Advanced Dental Science and Technology" as a collaborative course at the Graduate School of Biomedical Engineering, and staff and students from various backgrounds such as engineering, medicine, pharmacy, and literature are enrolled as well as those from the dentistry. We are also promoting interdisciplinary research and industry-government-academia collaboration research.
