Higher magnification images that show the difference between BCP and β-TCP about new bone formation and osteointegration. In images a and b, different samples show β-TCP reabsorption and new bone deposit among persistent particles (white arrows). Images c (BS-SEM) and d (histology stain with toluidine blue) show BCP rounded and integrated by bone tissue (black arrows). Note in image d the osteocytic cells orientation that follows the particle surface form. a and c, images obtained by BS-SEM; b and d, histology samples stained with toluidine blue
