A Morphological Evaluation of the Antibiofilm Activity on an Implant Surface Using a New Electric Device: An In Vitro Study

Background: Peri-implantitis, the most prevalent cause of implant failure, is a multifaceted issue that is influenced by various factors that promote biofilm formation around the implant. Although various innovative methods for microbiological decontamination of dental implants exist, a universally accepted standard protocol has not yet been established. However, the potential of a device that generates an electric current (Ximplant®) in reducing the survival of microorganisms within the biofilm is a promising development. Methods: In this in vitro study, five dental implants, contaminated using a microbial culture from a sample of saliva of a patient suffering from peri-implantitis, were decontaminated using the Ximplant® peri-implantitis protocol. The experimental conditions included a simulated peri-implant site and a subsequent fluorescent assessment of the Live/Dead microbial population. Results: The qualitative and quantitative image analyses showed a predominant dead light signal on the treated sample, demonstrating the potential efficacy of applying the electrostatic field to the contaminated implant surface in reducing the viability of the microorganisms within the biofilm around dental implants. Conclusions: These findings could inspire a new era in peri-implantitis treatment.
