Purpose The aim of our study is to evaluate the ability of a new type of implant (Konus Implant System®, Industrie biomediche e farmaceutiche, Italy) to isolate the internal of an implant-abutment connection from the external environment. Materials and methods To identify the capability of the implant to protect the internal space from the external environment, the passage of genetically modified Escherichia coli across implant-abutment interface was evaluated. Implants were immerged in a bacterial culture for twenty-four hours and then bacteria amount was measured inside implant-abutment interface with Real-time PCR. Results Bacteria were detected inside all studied implants, with a median percentage of 18% for Porphiromonas Gingivalis and 19% for Tannerella Forsythia. Conclusion The reported results are similar to previous work. Konus Implant System® showed bacterial leakage similar respect others implant systems (18% Porphiromonas Gingivalis, 19% Tannerella Forsitya versus 20% of Bicon© and Ankylos ® systems). In spite of the limits of our study, none two-piece implant system has been demonstrated to perfectly close the gap between implant and abutment.
