Nayab et al. reported the effects of Ca PIII&D on the interactions
between cells and implanted titanium surfaces [33]. Three Ca ion
flucences (high, medium, and low: 1

at 40 kV. Their study disclosed that the Ca implantation fluence
significantly influenced the shape of MG-63 cells on the titanium

MG-63 cell adhesion onto Ti discs implanted with high,
medium and low ion fluences of Ca. The bars show the average
adhesion of the cells on the Ca-implanted surface relative to
the numbers on the Ti (control) surface after cell culturing for
4 h and 24 h, which is defined as 100%. The error bars are
from three replicate experiments. The average cell adhesion
onto the control (non-implanted) Ti surface was 571 cells
at 4 h and 668 cells at 24 h (approximately 58% and 69% of
the cells added initially), respectively. * denotes statistically
significant differences in cell adhesion between the Ca (high)-
