Research Currently in Progress

Dr. Tözüm was the primary- and co-investigator of many research activities including periodontal and peri-implant health and disease (inflammatory markers of periodontal crevicular fluid and peri-implant sulcus fluid), comparative soft tissue grafting surgeries, regenerative procedures related to hard tissue applications, evaluation of sinus hard tissue regenerative grafting by histomorhometry and micro-tomography. His studies also included understanding the stability and mobility values of immediate/early/delayed loaded dental implants and the impact of different kinds of prosthetic loading of implants in health and disease, evaluation of bone quality and quantity of jaw bones in spiral/medical tomography and cone beam/dental computed tomography as well as the association between bone density and stability evaluations of dental implants, esthetic analysis of endosseous implants, understanding the vital anatomic structures and landmarks of jaws.
