Comparative evaluation of microbial contamination in and periodontitis and periimplantitis. Review

At the present stage of the development of dentistry, dental implantation occupies a leading place in the system of complex rehabilitation of patients with defects in the dentition. The success of dental implant placement depends on many factors. Among the significant reasons influencing the positive outcome of transplantation, the state of microbiocinosis of the oral cavity of patients should be noted. The perimplant zone is a favorable habitat for anaerobes. The pathological process in the form of periodontitis, which is often the reason for the loss of teeth and the placement of implants, contributes to the progression of the inflammatory process in the periodontal tissues. This article provides an overview of the scientific literature devoted to the study of microflora in inflammatory periodontal diseases. We conducted a comparative assessment of the microbiota in periodontitis and peri-implantitis, which, according to individual authors, are different ecosystems in terms of the composition of microorganisms. Alternative views on this issue were considered. Based on the analyzed scientific data, we made a conclusion about the similarities and differences in the oral microbiota in periodontitis and peri-implantitis, as well as in their combined course. We substantiated the feasibility of assessing microbial pathogens in the peri-implant area in order to develop preventive and therapeutic measures aimed at the long-term survival of dental implants.
