Fig. 5From: Effects of micro-porosity and local BMP-2 administration on bioresorption of β-TCP and new bone formationResidual β-TCP. The residual amount of β-TCP in group A was greater than that in group B at every period, but statistical significance could not be demonstrated. The residual amount of β-TCP in group C was significantly lower at every period compared to that in group B (*p < 0.05)Back to article page
