Objectives The aim of this study was to follow patient cases retrospectively in a longitudinal manner from the time of implant placement to the time they were diagnosed with peri‐implant disease, and to identify associated clinical and microbiological features of peri‐implant disease. Material and methods A total of 281 patient cases were chosen from the archives of the Oral Microbiological Diagnostic Laboratory, G othenburg, S weden, based on bacterial samples taken from diseased implants. A form was designed and filled in separately for each case including data on patient, implant and disease profile. Results Most cases were severe peri‐implantitis cases (91.4%). In 41.3% of the patients, peri‐implantitis was developed early, already after having implants in function less than 4 years. The type of implant surface was significantly associated with the time in years implants were in function, before disease was developed ( P < 0.05). The microbiological results by both culture and checkerboard analysis, although failed to fully correspond to the severity of the disease in terms of magnitude, proved to show that peri‐implantitis is a polymicrobial anaerobic infection with increased number of AGNB (aerobic G ram‐negative bacilli) in 18.6% of the patients. Conclusions Peri‐implantitis is a biological complication of implants in function that poses a threat to their long‐term survival. It may develop earlier around implants with rough surfaces and it may represent a true infection. Microbiological sampling methods should be improved and uniformed so as to fully unveil the microbiological profile of the disease.
