Prof. Marc Quirynen, DDS, PhD, earned his dental degree in 1980 and his Certificate in Periodontology in 1984 from KU Leuven. He subsequently completed his PhD in 1986, investigating the anatomical and inflammatory mediators of bacterial plaque retention. Currently serving on the postgraduate Periodontology faculty at KU Leuven and as a Visiting Professor at Egas Moniz University, Prof. Quirynen is an internationally recognized pioneer in tissue regeneration. His research and clinical focus centers on the application of autologous platelet concentrates (APCs) in periodontal regeneration and implant dentistry. He authored the definitive text 'Leucocyte- and Platelet-Rich Fibrin (L-PRF) in Oral Regenerative Procedures' and guest-edited the landmark 'Periodontology 2000' monograph on APCs, synthesizing contemporary evidence alongside leading experts such as Dr. Richard Miron and Dr. Catherine Davies.
