Abstract :
To evaluate the damage induced by the CAD/CAM milling procedure on the mechanical prepared of zirconia. At lest 15 zirconia bars for each group were prepared. Control group is prepared by pressed while experimental group is cut with a diamond blade from a block of yttria-stabilized zirconia ceramic. There is no statistically significant differences between the groups (p> 0.05). So milling did not influence mechanical properties of Y-TZP zirconia.
