Dr. Tozum graduated from Gazi University, Faculty of Dentistry, Turkey with the Top Student Award in 1998. He completed his integrated post-graduate clinical education in periodontics specialty and Ph.D. training about bone metabolism at Hacettepe University, Turkey and University of Michigan, Ann Arbor between 1998 and 2002. He has been teaching, researching and practicing about advanced periodontics and implant dentistry since 2002, and affiliated as full-professor of periodontics and associate dean of dentistry at Hacettepe University. He has been appointed as an associate professor at University of Illinois at Chicago (UIC) since 2014.

He received three international awards in implant dentistry, including Travel Award at International Association for Dental Research Continental European Division Meeting in 2004; Platinum Award at 24th World Congress-International Congress of Oral Implantologists in 2006; The Best Article published at ACTA Odontologica Scandinavia in 2009 related to bone grafting. He is a fellow and is also a member of research grant, web site education and newsletter committees of Academy of Osseointegration (AO), fellow of International Congress of Oral Implantologists (ICOI), diplomate and honorary member of Meffert Implant Institute, active member of European Federation of Periodontology, Turkish Associations of Periodontology and Oral Implantology.

He has been invited to more than 50 national/international scientific meetings as an invited or keynote speaker, has published 6 book chapters, over 100 scientific manuscripts and 75 presentations related to advanced periodontics and implant dentistry. He has also been serving as an editorial board member of 20 leading journals, such as Clinical Oral Implants Research, Clinical Implant Dentistry and Related Research, Implant Dentistry, The Journal of Implant and Advanced Clinical Dentistry, Journal of Contemporary Dental Practice (Associate Editor), Journal of Oral & Maxillofacial Research. Dr. Tozum’s manuscripts are globally cited 883 times (h-index: 17) at Thomson Reuters (Science Citation Index), 1179 times (h-index: 20) at Scopus, and 2067 times (h-index: 24) at Google Scholar by May 2016. He has also built an international scientific clinical research group focused on cone beam tomography imaging including Spain, Lithuania, Turkey, Cyprus, S. Arabia and U.S.A (UIC and University of Michigan).

Clinical activities & specialties

He is currently supervising post-graduate periodontics clinic, conducting clinical implant related research (implant stability, cone beam computed tomography, micro-tomography, histomorphometry, immediate/early loading of implants and soft/hard tissue augmentations) and taking care of patients at faculty specialty practice at UIC related to periodontics and dental implants.

Research Currently in Progress

Dr. Tozum's research is focused on implant dentistry, including implant stability—resonance frequency and analysis, damping capacity assessment, and insertion torque values; marginal bone loss and gain around implants; and peri-implant crevicular fluid evaluation (nitric oxide, myeloperoxidase, ICTP, and osteocalcin) for the long term.

His clinical research includes  implant stability, cone beam computed tomography, micro-tomography, histomorphometry, immediate/early loading of implants and soft/hard tissue augmentations.
