Dr. Ralf-J. Kohal has been the Representative Professor of the Department of Prosthetic Dentistry, Center for Dental Medicine, Medical Center – University of Freiburg, Germany since October 2016. He got his doctoral degree (Dr. Med. Dent.) in 1991. From 1993 – 1995 he was a Visiting Assistant Professor at the Division of Periodontology, University of Texas, Houston, Texas. Dr. Kohal is Board Certified in Prosthodontics (DGPro) and has received a certification for Oral Implantology (German Society of Implantology, DGI). In 2002, he was awarded docent ship (Dr. Med. Dent. Habil.) in Oral Health Sciences through the University of Freiburg. His main interests are located in the field of implantology (ceramic implant materials, guided bone regeneration, sinus augmentation, guided implant surgery) and prosthodontics.




Prof. Michael PAYER:

  • Vice Chair of the Department of Oral Surgery and Orthodontics, Medical University, Graz, Austria
  • Expertise:  Clinical and experimental implant dentistry, augmentative & oral surgery, stem cell biology scaffold materials & tissue healing, material research.

Prof. Michael PAYER has performed clinical and experimental research with zirconia and zirconia implants for years. He published more than 35 papers on the topic of implant dentistry and is cited more than 230 times. He has presented numerous invited lectures on the topic of zirconia and is the current president of the Austrian Society of Oral Implantology (ÖGI)   


Prof. Valter SERGO:

  • Faculty of Engineering, University of Trieste
  • Expertise: Spectroscopic methods – Characterization of advanced ceramic materials for structural and functional applications

Prof. Valter SERGO has published over 100 technical papers. His papers have been cited by the scientific community more than 1500 times with one paper more than 400 times and 2 papers more than 100 times (in the field of Materials Science, the citation threshold of top 1% scientists is, according to Essential Science indicators, around 600 citations. A joint examination of Scopus and WoS indicates an H-factor of 21 for prof. Sergo). Prof. Sergo is a regular referee of the Journal of the American Ceramic Society and occasional referee of other journals, mainly for papers devoted to spectroscopy of inorganic materials (Biomaterials, Journal of Materials Science, Journal of Materials Research, Applied Spectroscopy, Journal of Applied Physics). He has presented over 50 invited lectures both at scientific meeting and institutions and at industrial companies worldwide.


Prof. Mike SWAIN:

  • University of Sidney, Australia
  • Expertise: Dental and Biomaterials research, nano-mechanics of materials and the role of disease state on the properties of biological tissue

Prof. Mike Swain for his expertise in the field of zirconia and dental ceramics. He is one of the most quoted author in the ceramic field. He has published more than 250 papers and has been cited more than 6000 times. Prof. Swain will be in Germany as an invited Professor at University of Freiburg during the several years. Moreover, his research aims to develop a basic understanding of the mechanisms responsible for the behavior of materials including ceramics, teeth and biological tissues. More particularly, the selection and assessment of coatings for a heart pump (with VentraCor), has recently been approved for clinical usage. In complement, the development of a number of patents has been associated with devices to measure the visco-elastic properties of biological tissue, and numerical modeling of the deformation and calcified tissue remodeling about loaded teeth and dental implants.
