(a) Hydroxyapatite-coated titanium screw in sheep vertebral pedicle. The red rectangle indicates the region of interest for histomorphometric measures; Toluidine Blue/Fast Green staining; magnification 1x. (b) Cylindrical titanium implant in sagittal section in sheep iliac crest. The red circles identify regions of interest for histomorphometric measures; Toluidine Blue/Fast Green staining; magnification 1x. (c) Histomorphometrical measure of bone ingrowth and mirror area of hydroxyapatite-coated titanium screw implanted in sheep vertebral pedicle. In red, the ROI for the assessment of bone ingrowth between the two turns of the screw; in yellow, the ROI for the assessment of the mirror area; Toluidine Blue/Fast Green staining; magnification 10x.
