It has been found that titanium, with a high degree of polishing and low wettability, is able to quickly hamper bacterial colonization, probably because the titanium surface does not allow bacteria to establish a permanent link. This effect disappears if roughness and wettability increase. The titanium surface characteristics also seem to select the morphotypes. In the smoother group the morphotypes are limited to the cocci group. The frequency of short-rods and long-rods increase with roughness and wettability. This result is remarkable because the cocci morphotype is typically related to healthy bone and soft tissue around oral implants. This work is a preliminary in the study of surface treatments able to reduce bacterial adherence on titanium dental implants.
