a, b Saw cuts of the core biopsy are shown in the upper parts of the original bone; the lower parts represent the augmented area. Here, some easy-graft particles are partially or completely embedded in osteoid or newly formed bone. New bone with integrated biomaterial forms dense trabeculae and exhibits a mature, lamellar structure. Interosseous and intergranular connective tissue is well perfused and free of inflammation (see also histomorphometric data and details). Newly formed bone (NB) is stained (dark magenta), original older bone (OB; light magenta), easy-graft (EG; dark brown), and soft tissue (light blue) (undecalcified ground sections stained with azure II and pararosaniline; overviews are compilations of several single photos, original magnification × 50). b For histomorphometric purpose were highlighted: easy-graft granules (light blue), osteoid (dark blue), and newly formed bone (red). The yellow line limits the region of interest. Tissue area under this line is set equal to hundred percent. c Graft particles (EG) tightly integrated in newly formed mature bone (NB) or blue-stained osteoid (O); different staining characteristics of newly formed bone and recently formed bone (RB). d, e Graft particles (EG) completely integrated in newly formed mature bone (NB) or broad seams of osteoid (O) including osteoblasts (ob); new bone (NB) is added to original bone (OB) displaying entrapped osteocytes (oc); densely vascularized connective tissue (CT); no signs of inflammation osteoid setting.
