Introduction: The literature has shown that colonization of the implant-abutment interface (IAI) by microorganisms may result in peri-implantitis and bone loss. Objective: The aim of this in vitro study was to analyze the sealing properties of flowable silicone at this interface in external hexagon implants undergoing loading tests. Methods: Two groups of external hexagon implants (n=10) were filled with blue dye. In the control group, no material was applied to the implant-abutment interface. The experimental group of specimens had silicone applied to this interface. Results: In all implants of the control group (with no silicone) IAI sealing failures occurred before reaching 100,000 cycles (cycle range from 20,000 to 79,720); whereas, all experimental group implants (with silicone) reached 1,000,000 cycles without sealing failures. Conclusion: The experiments showed that the experimental group presented significantly increased capability of sealing the IAI in comparison with the control group (p < 0.001).
