Sažetak
Peri-implantitis is an inflammation around a dental implant. Bacteria settle in the tissues around the implant and inside the implant due to the passage of microorganisms through the microgap at the connection of the implant and the prosthetic abutment. Persistent inflammation over time causes bone resorption over time, which can lead to implant loss. There are different ways to treat and prevent peri-implant diseases. One of the ideas of preventive measures is the use of sealing materials and antimicrobial materials to decontaminate the implant abutment interface and consequently prevent the colonization of microorganisms and their impact on the occurrence of peri-implant diseases. A review of the current literature shows a lack of independent studies on this issue. The purpose of this study was to evaluate the antimicrobial efficacy and permeability of different types of the sealing materials at the connection of prosthetic abutment and dental implant in static conditions and the influence of implant and prosthetic abutment platform type on sealing quality of different materials. Furthermore, the influence of prosthetic abutment fabrication method on microbial leakage at the implant abutment interface in static conditions was evaluated. The use of different sealing materials showed no difference in the antimicrobial effect and permeability for microorganisms compared to the negative control groups. Implant abutment interface platform type did not significantly influence the sealing efficacy regardless of the sealing materials use. There was also no statistically significant difference between original and third – party prosthetic abutments regarding sealing efficacy. The clinical implication of this research is that it offers an answer to the question whether the routine use of such materials is justified.
