Efficacy of a new implant-abutment connection to minimize microbial contamination: an in vitro study.

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.
