- Fig. 2. The various regions evaluated at the histomorphometric analyses. Bone walls (red arrow); middle (white arrow); sub-mucosa (yellow arrow); close-to-window (orange arrow). The antrostomy region was also evaluated at the medial and lateral edges (dark green arrows) and in the middle aspect (light green arrow) : Influence of the use of autogenous bone particles

- Fig. 5. Photomicrographs of decalcified sections illustrating the healing after 8 weeks. Both at the treated (a) and untreated (b) sites, the antrostomy was closed in most cases, presenting residual defects of various dimensions in the outer side. New bone was connecting the lateral and medial sinus walls. The middle and sub-mucosa regions were not healed completely yet. Scarlet-acid fuchsine and toluidine blue stain.

- Fig. 6. Photomicrographs of decalcified sections illustrating the healing after 8 weeks. a Treated site. Most of the antrostomies presented remaining defects in the outer contour. b, c Untreated sites. Two antrostomies of the treated sites and four of the untreated sites appeared not closed with corticalized bone and presented connective tissue interposed between the edges of the antrostomy.

After 8 weeks, woven bone was still found forming ridges towards residues of provisional matrix, showing that the healing was not completed yet.
