A comparative evaluation of changes in microbial flora in delayed and immediate placed implants: An in vivo study

Abstract

Background: Dental implants provide a unique opportunity for the observation of initial bacterial colonization and also for the estimation of time needed for the establishment of complex microflora. While many factors are important in determining the long-term success or failure of dental implants, very little is known about the relative importance of the subgingival bacterial populations around implants. Aim: The aim of the study was to estimate peri-implant microbial colonization in patients with immediate and delayed implants and the differences in peri-implant microflora between immediate and delayed implants. Materials and Methods: In the current study, the organisms found in the oral cavity prior to placing the implants and during the various stages of implant treatment in both the categories were assessed. Results: In the current study, organisms such as Streptococci are consistently seen. The presence of organisms such as Porphyromonas gingivalis and Fusobacterium, which have pathogenic potential, is of importance. Conclusion: In this study, the following conclusions were made; the mode of implant placement either immediate or delayed does not alter the peri-implant microflora. Organisms present preoperatively were consistently present during the entire phase of the treatment. This study suggests that regular microbial evaluation along with clinical and radiographic monitoring could help in recognizing the potential for peri-implantitis and in the prevention of the same for better prognosis.
