Dr. Takahiro Ogawa is widely recognized as an expert in designing and creating novel titanium and zirconia surfaces, implant biologic research, and photoenergy-mediated activation of implant materials, known as UV-activation. Dr. Ogawa is a Professor in the Division of Regenerative and Reconstructive Sciences and Weintraub Center for Reconstructive Biotechnology at UCLA School of Dentistry and a leader of Team Surface. He has published 200+ papers in peer-reviewed scientific journals with a total impact factor of 1,000+, total citations of 10,000+, and h-index 60. He is ranked world top 0.57% scientist across the fields in the most recent Stanford World Scientist Ranking. He spoke over 150 times in the invited lectures and symposia worldwide. Dr Ogawa and his team received over 40 scientific awards from the national and international meetings and societies. Dr Ogawa is a recipient of IADR/AADR William J. Gies Award, American College of Prosthodontists (ACP) Clinician/Researcher Award, International Congress of Oral Implantologists (ICOI) Ralph V. McKinney, Jr Award, and Academy of Osseointegration (AO) William R. Laney Award, and IADR Distinguished Scientist Award. He is a former president of IADR Prosthodontic Group.

Overcoming 30 years of stagnation of implant surfaces

Unfortunately, implant surfaces, regardless of dental or orthopedic surgical implants, have not improved significantly in the past 30 years.  Our research team called Team Surface focuses on science and technology of implant surfaces. Witness a part of our works here and do not miss the Ogawa Lab Surface Science and Technology page and our own website.

Photofunctionalization is rapid, chairside conditioning of dental implants. The conditioning removes hydrocarbons that unavoidably and unexceptionally accumulated on implant surfaces during normal aging and regenerates hydrophilicity on the surfaces. Clinical and basic studies indicated that photofunctionalization accelerates and enhances bone healing and bonding around dental implants, resulting in the reduced treatment time, high success rate, less complications, marginal bone preservation, and more opportunities for less invasive surgery in dental implant therapy.
