Static Bacterial Leakage in Different Conometric Connections: An In Vitro Study

This in vitro study aims to evaluate the bacterial microleakage of three conometric connections. Sixty dental implants (3P implafavourite Scalenghe) were divided groups (n = 20): Cone–Morse with passing screw (Group 1); solid abutment 2); and Conometric connection esthetic 3). The fixed resin bases. Then, 1.0 µL Streptococcus oralis (SO) was inoculated internal platform 10 fixtures for each group, another Pseudomonas aeruginosa (PA). abutments then screwed, five from subgroup randomly selected SEM inspection ensure that installed correctly. Data submitted statistical analysis, ANOVA Fisher’s Least Significant Difference (p ≤ 0.05). turbidity broth monitored 14 days follow-up order determine penetration suspension into surrounding solution, but observation samples lasted until 90th day, which there no difference between two. Microbial contamination found 30%, 20%, 50% Group 1, 2, 3, respectively, statistically significant differences groups, PA showed greater infiltration than SO. Although found, cone morse connections lower percentages, respective 18° angle.
