Occurrence of Peri-Implant Microflora in Single vs. Two Piece Implants

Abstract

Objectives: Orthodontic mini-implants and dental implants become unstable in the event of peri-implant inflammation. The analysis of microbial colonisation in these implants would enhance the prolonged success rate of the implant approach. Thus, the present study aimed to determine the microbial colonisation in both single and two-piece implants on healthy individuals in order to elucidate the aetiology of infections following implant surgeries. Materials and Methods: In all, five clinical samples were collected from mini-implants from patients undergoing orthodontic treatment and at least from two dental implants. The samples were collected using three 35# paper points. The colonies were identified and counted microscopically, and the number of viable microorganisms was calculated with respect to the number of colonies. Results: Streptococcus spp., Lactobacillus casei, Candida spp. and Staphylococcus aureus colonisations were identified based on the cell growth methods. Conclusion: Microorganisms had accumulated around the dental implant and mini-implant surfaces before the healing post-abutment placement. Thus, further studies are essential on a variety of organisms to understand the mechanism underlying biofilm formation.
