Broad Research Interests encompass the host’s immune response during periodontal tissue disorders, with focus on the biology of peri-implantitis. Objective: to conduct clinical trials for the in situ application of non-invasive optical coherence tomography imaging for screening in real time peri-implant inflammatory conditions before clinical signs reveal the destructive processes. The method can save osseointegrated implants by allowing early treatment of the complication.
