(a) Microtextured surface in graft: General overview shows a clear demarcation with different bony trabeculae between the most apical grafted area (graft) and the more coronal native bone (basal) (Toluidine blue, original magnification ×8). (b) Microtextured surface in graft: The trabeculae in the regenerated area are randomly arranged and their thickness and connection are determined by the shape and size of the embedded graft particles (Toluidine blue, original magnification ×25). (c) Microtextured surface in graft: Magnification of the regenerated area shows a mix of bone (arrows), graft particles (G), and graft powder (P) contacting the implant surface (Toluidine blue, original magnification ×50). (d) Microtextured surface in graft: Magnification of the apical interface shows a mix of graft powder and particle fragments without cells immersed in a mineralized matrix (Toluidine blue, original magnification ×50)
