Purpose. The aim of the present study is to evaluate the effectiveness of Ditron implants abutment connection (IAC) to sealing the gap between two pieces. Materials and methods. To identify the efficacy of a new IAC, the passage of genetically modified bacteria across IAC was evaluated. A total of five Ditron Implants were used. All implants were immerged in a bacterial culture for forty-eight hours and then bacteria amount was measured inside and outside IAC with Real-time PCR. Bacterial quantification was performed by Real-Time Polymerase Chain Reaction using the absolute quantification with the standard curve method. Results. In all the tested implants, bacteria were found in the inner side, with a median percentage of 1.35%. The analysis revealed that, in untreated implants, bacteria grew (internally and externally). Moreover, the difference between outer and inner bacteria concentration was statistically significant at each time point. Conclusions. Ditron Implant IAC (MPI, Ditron Dental, Israel) is efficacy in reducing bacterial leakage.
