Dr. Satoshi Komasa is an Associate Professor within the Department of Oral Health Sciences, Faculty of Health Sciences, Osaka Dental University. Drawing on his expertise in prosthodontics, dental materials science, oral regenerative medicine, and biomedical engineering, Dr. Komasa conducts research on the functional enhancement and clinical application of biomaterials used in dentistry. His primary research interests include nanostructure control, coating technologies, and surface modification of dental biomaterials such as titanium, zirconia, and polyetheretherketone (PEEK). His research aims to improve the hydrophilicity, biocompatibility, antibacterial properties, and osteogenic potential of material surfaces, thereby promoting the early stabilization and long-term success of dental implants. Dr. Komasa actively promotes interdisciplinary and interinstitutional collaboration with researchers in dentistry, materials science, surface engineering, plasma engineering, and regenerative medicine. As a result, he has established collaborative research programs with numerous universities and research institutions and has also been involved in multiple patent applications. His work seeks to create an integrated pathway from basic research to intellectual property development, product innovation, and clinical application. By bridging materials science and clinical dentistry, Dr. Komasa aims to develop safer, more functional, and more durable dental materials and treatment methods. He places particular importance on translating research findings into clinical practice and continues to contribute to education, research, and patient care with the goal of improving oral function and quality of life.

Collaboration of Chemical Engineering and Dental Medicine Based on New-type Gels

Bio
Dr. Yoshiro Tahara obtained his Ph.D. from Kyushu University in 2012 under the supervision of Prof. Masahiro Goto. His key research focus was “Transdermal insulin delivery and transcutaneous vaccination using a solid-in-oil nanodispersion”. Between 2012 and 2017, Y. Tahara belonged to Kyoto University as a post-doctoral researcher; the Supervisor of the laboratory was Prof. Akiyoshi Kazunari. During this time, novel nanogel-based materials such as nanogel-cross-linked microsphere and porous gels for tissue engineering were developed. Between 2017 and 2019, Y. Tahara returned to Kyushu University as a postdoctoral researcher under the supervision of Prof. Goto. During this period, research on a solid-in-oil-in-water emulsion as a novel immunostimulatory adjuvant was published. In 2019, Y. Tahara joined Doshisha University as an Associate Professor, working in the same laboratory as Prof. Michiaki Matsumoto, a researcher in chemical engineering. In 2026, Y. Tahara was promoted to Professor at Doshisha University, and is also currently chair of a committee of young researchers within the Japanese Society for Biomaterials in the Kansai region. On 1st August 2026, the conference of the Japanese Society for Biomaterials in the Kansai region for young researchers will be held at Doshisha University.

Novel Bioceramics for Bone Repair and Regeneration Medicine

Bio
Dr. Tetsuya Adachi is a clinician-scientist and Associate Professor in the Department of Dental Medicine at Kyoto Prefectural University of Medicine (KPUM). His research centers on biomaterials, including ceramics and polymers, as well as anti-aging science. Dr. Adachi’s laboratory investigates the extracellular matrix of naked mole-rats with the aim of elucidating the mechanisms underlying their remarkable anti-aging effects. Through this work, his group seeks to advance understanding of how extracellular matrix biology can contribute to regenerative medicine, biomaterials research, and age-related disease prevention. In addition to his research, he is actively engaged in managing and fostering interdisciplinary researcher communities, an activity that has become one of his major professional interests. He aims to establish an independent research program that integrates bioengineering, immunology, and translational biomaterials to bridge basic research and clinical application.

Collaborative Research Between Mechanical Engineering and Dentistry in the Field of Bioengineering

Bio
Dr. Hideaki Sato is an Associate Professor in the Department of Mechanical Engineering, Faculty of Science and Engineering, at Tokyo City University. His area of expertise is abrasive machining, including grinding and polishing. Although affiliated with the Department of Mechanical Engineering, he is also a member of dental academic societies and conducts research related to dentistry. He has explored research areas in dentistry where mechanical engineering principles can be applied and has sought out relevant research topics. He is currently researching the polishing of dental materials such as pure titanium, hybrid resin, and PEEK. He has devised a new sodium-alginate-bonded mounted wheel; fabricated a custom polishing apparatus; and evaluated its polishing characteristics. He also focuses on agar particles, utilizing them in a blasting cleaning for dental materials. Agar is soft and highly biocompatible, making it very unlikely to cause scratches in dental materials. Additionally, he is researching a method to impart antibacterial properties to denture base materials by peening them with apatite, thereby transferring apatite onto the surface. When a mechanical engineering researcher conducts dental research, finding excellent collaborators is crucial to ensure the research stays on the right track; this significantly influences the future development of the work. In Japan, very few researchers affiliated with science and engineering universities participate in dental academic societies. While there are some researchers from the field of chemistry, there are hardly any from the field of mechanical engineering. Unless this situation improves, and more researchers in the fields of science and engineering take an interest in dentistry and engage in dental research, we cannot expect significant progress in the field. In this webinar, I will share the experiences I have gained through collaborative research with dentists.
