The purpose of this study is to determine the predominant periodontopathogenic microbiota in peri-implant sulcus of osseointegrated implant of a healthy patient. A healthy patient with good periodontal condition was selected for AQB single-piece implant placement. Periodontal pathogens were checked in patient's saliva prior to implantation. F. nucleatum (0.25%) and B. forsythensis (0.01%) were detected. An HA-coated one-stage implant (AQB) was implanted in the missing lower second molar region. Then samples were collected from the peri-implant sulcus using paper point, every month for eight months after the implantation and fixation of porcelain crown. RT-PCR (invader method) was used to detect the periodontal pathogens. No periodontal pathogens were observed up to three months. F. nucleatum (0.16 %) was detected at three months, T. forsythensis (0.06%) and F. nucleatum (0.06%) were detected after four months. A. actinomycetemcomitans (0.054%) and F. nucleatum (3.29%), were detected at six months. F. nucleatum (5%), (1.58%) were detected at seventh and eighth month.
