Graft particles showing various grades of resorption after 2 weeks of healing. New bone was found surrounding the graft particles in the periphery (outer bone; OB) and spreading inward the graft particles in small quantities (interpenetrating bone network; IBN). Soft tissues, cells and vessels are visible within the graft. Osteoclastic zones were found in the periphery of the graft (red arrows in a and b indicate some examples). a, b Plasma group. c, d Control group. a–c Bone wall regions. b–d Sub-mucosa regions. The asterisks indicate examples of OB (yellow) and IBN (green). Stevenel’s blue and alizarin red stain
