ABSTRACT

Purpose: The purpose of this systemic review and meta-analysis was to estimate the colony of microorganisms on bone-level implants at the implant-abutment interface (IAI) and to find its similarity with peri-implant conditions. Study selection: The study was emphasized for implants in function for at least 1 year, whether the two-piece osseointegrated implants, associate to rise in the number of bacterial colonization and the outcome of peri-implantitis, in comparison to healthy peri-implant condition. Using a mixture of MeSH (Medical Subject Headings) and search terms the Search strategy circumscribes the on-line (MedLine, Google Scholar, Cochrane library) literature from 1990 till March 2015 which was published in English. According to the ARRIVE and CONSORT statement guidelines, quality assessment of carefully chosen full-text articles was achieved. The total bacterial count was calculated and equated to IAI with or without peri-implant pathology for Porphyromonas gingivalis, Fusobacterium nucleatum, Treponema denticola, Tannerella forsythia, and Prevotella intermedia. Results: The inclusion principles and quality assessment were fulfilled from a total of 14 articles, and 1029 implants record. According to the studies patients with the two-piece implant system displayed the contamination of IAI. A substantial difference in total bacterial count between implants affected by peri-implantitis versus healthy peri-implant tissues (0.3870.055; 95% CI 0.279–0.496) were indicated by meta-analysis. However, except for T. forsythia, less bacterial colonization was noticed in the healthy IAI for all the examined gram-negative bacteria. Conclusions: An increase in bacterial colonization with peri-implantitis in comparison to those present in healthy peri-implant tissues was substantially reported for periodontal pathogenic bacteria in the IAI patients.
