Titanium alloy TC4(Ti6Al4V) used as dental implant materials were modified by different surface modification technologies. The bacterial adhesion method and the tagging effect of fluorescence were employed to evaluate antibacterial property of modified surfaces by observing bacterial adhesion status and counting quantities of bacterial adhesion on the Ti6Al4V surfaces below the fluorescence microscope;SPSS software was used to analysis and compare the antibacterial property of modified surfaces at the same ...
