Brief Summary

Peri-implant diseases, which are the most common biological complications of dental implants, are inflammatory diseases characterized by soft tissue inflammation and loss of supporting bone tissue in the tissues around the implant. The most basic factor in the onset of peri-implant diseases is bacterial biofilm formation. Therefore, the gold standard in its treatment is plaque removal. It has been stated that mechanical treatments with conventional plaque removal methods, usually applied using curettes in the treatment of peri-implantitis, are unpredictable and that positive clinical results are valid for short periods such as 6-12 months. This result can be explained by the inability to provide sufficient debridement on the rough implant surface. For this reason, it has been shown that the use of air abrasion systems based on the principle of cleaning the surfaces by applying an abrasive powder with compressed air may be beneficial in order to increase the success of the treatment. When the literature is reviewed, it is seen that there is no standard clinical protocol for the use of air abrasion devices as a mechanical debridement method for non-surgical peri-implantitis treatment. In the pathogenesis of peri-implant disease, cytokines that manage the inflammatory process play a major role. RANK ligand (RANKL), osteoprotegerin (OPG) and TWEAK are biomarkers that play a role in bone metabolism. Examination of cytokines and such biomarkers that play a role in bone metabolism in the peri-implant crevicular fluid (PIOS) at the initial stage and during the post-treatment follow-up processes and recording clinical findings may be useful in evaluating the effects of alternative treatment methods on disease control. For this purpose, it is planned to include 60 patients aged between 18-65 with dental implants with a probing depth of 6 mm or more in one or more areas of the mouth in the study. Patients will be randomized into 3 groups as A: Non-surgcal treatment with titanium curettes, B: Non-surgcal treatment with air abrasion device and C: Non-surgcal treatment with titanium curettes + air abrasion device. Initial clinical periodontal parameters of all patients will be recorded and PIOS samples will be obtained. Following appropriate treatments for the determined group, clinical indices will be recorded and PIOS sampling will be repeated in the 3rd and 6th months. IL-10, IL-17, RANKL, OPG and TWEAK levels in the PIOS samples will be determined by ELISA test and the findings will be evaluated with appropriate statistical analyses.
