Healing after 10 weeks. Higher amounts of newly formed bone were observed in this period of healing compared the previous period analyzed, in both the plasma group (a, b) and the control group (c, d). New bone was penetrating from the peripheral regions (outer bone; OB) inside the remnants of graft particles forming a network of bridges interconnecting the peripheral bone with the biomaterial through its porosities (Interpenetrating bone network; IBN). a Central region. b–d Sub-mucosa regions. c Next to the bone wall region. The asterisks indicate examples of OB (yellow) and IBN (green). Stevenel’s blue and alizarin red
