Abstract

OBJECTIVE:

The aim of this study was to evaluate the possible leakage of 3 species of bacteria (Streptococcus sanguinis, Fusobacterium nucleatum, and Actinomyces odontolyticus) and of Candida albicans and Candida glabrata in osseointegrated implants with different implant-abutment interface (IAI) geometry.

MATERIALS AND METHODS:

Two groups of implants, (1) implant-abutment unit with a tube-in-tube interface and (2) implant-abutment unit with a flat-to-flat interface closed with different torque values, were compared in the study. In the first phase, the implants were assembled and cultured in vitro for 7 days. The implants and abutments were disconnected and samples were taken and cultured. In the second phase, the internal part of each implant was inoculated with 0.1 ┬ÁL of microbial broth and then connected to the respective abutments. Afterward, medium samples were taken and cultured.

RESULTS:

The group 1 implants were more resistant to colonization than those of group 2 (P < 0.05). The intragroup difference was significant between the implant-abutment units assembled with the recommended torque values and those with lower torque values (P < 0.01) for both the groups.

CONCLUSION:

IAI geometry influences both bacterial and yeast colonization inside the implants as well as the torque value used to connect abutments to implants.
