Fig. 3From: Novel use of cranial epidural space in rabbits as an animal model to investigate bone volume augmentation potential of different bone graft substitutesHigher 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 blueBack to article page
