Non-decalcified histology of (a) calvarial and (c) alveolar scaffolds and (b) calvarial and (d) alveolar bone graft showed blood vessels stained with stevenel’s blue with surrounding organized bone (white arrows). Patent sutures without evidence of disruption or premature fusion (green arrows) were visualized adjacent to calvarial and alveolar reconstruction in all samples without evidence of ectopic bone formation or inflammatory cells. All scale bars = 1 mm.
