The purpose of the present study is to compare the 1-year clinical, radiographic and microbiological outcomes and patients' satisfaction following surgical treatment of peri-implantitis after applying two different surface modification methods. Secondarily, analysis and comparison of the microbiological results of implants diagnosed and treated for peri-implantitis with healthy implants will be performed.
