Popis: This study examines the microbiota associated with the progression of experimental peri-implantitis and periodontitis induced concurrently in partially edentulous adult monkeys. Root-form and plate-form implants with fixed prosthesis in place for at least 12 months and their corresponding opposite molar teeth were ligated for 6 months. The microbiota in plaque around these ligated dental implants and molars were studied at 0, 1, 2, 3, and 6 months post-ligation. Plaque samples were analyzed by dark-field microscopy and selective and non-selective culture. Putative periodontal pathogens were detected as a major component of the microbiota cultured from plaque samples obtained from experimental peri-implantitis sites. Overall, the types and relative proportions of putative periodontal pathogens in plaque associated with ligature-induced peri-implantitis and ligature-induced periodontitis were similar. Only levels of anaerobic Actinomyces and spirochetes were significantly different between both sites. Spirochete levels were significantly higher at peri-implantitis sites when compared with levels at periodontitis sites after 6 months, and spirochete levels increased significantly between 0 and 6 months post-ligation at implant sites. Levels of spirochetes correlated significantly with probing depth and bone loss at peri-implantitis sites. Overall, Actinomyces levels were higher at periodontitis sites. Porphyromonas species were not detected continuously as part of the peri-implantitis microbiota. In conclusion, this study finds that the microbiota associated with the progression of experimental peri-implantitis and periodontitis occurring concurrently in partially edentulous mouths are similar.
