Abstract

The pattern and the amount of plaque growth on titanium oral implants were examined using a human in vivo model. Forty eight discs of titanium grade IV with a diameter of 4 mm were divided into three groups and treated with different polishing procedures to obtain different surface roughness. The surface roughness of the specimens was verified by a laser profilometer. Wettability was verified by calculating the dynamic contact angle. A stent from each subject was immediately processed for microbiological analysis and the other one for scanning electron microscopy to determine both the morphotypes and the amount of bacterial colonization. Results suggest that titanium with high degree of polishing and low wettability can prevent bacterial colonization.
