Mandibular Ridge Augmentation Using a Mineralized Ilium Block: A Case Letter

Atrophy of the lower jaw.

Preoperative template scan.

Figure 3. Full-thickness dissection of atrophic area. Figure 4. Grafting of atrophic area with 3 mineralized human ilium block allografts. Figure 5. One of the cortical plates will be removed based on the surgeon's evaluation and surgical need. Figure 6. Three-month exposure showing stable grafting. Figure 7. Prepared implant site after ridge osteotomy.

Section 41 of the cone beam computerized tomography image clearly shows retained pin and the presence of a maturing cortical plate and cancellous bone within the alveolar ridge

Core taken for histologic study at 10 months. Excellent healing is obvious along with adequate space for dental implantation.

(a) Magnification (×5 original) showing the interface between native bone and allograft. (b) Magnification (×10 original) showing new bone surrounding the allograft spicule. (c) Magnification (×10 original) showing active bone marrow development. The figure clearly illustrates allograft bone (AB), a Haversian canal (HC) forming in the area of allograft initiating remodeling, and an area of new bone (NB) with osteocytes clearly visible within the lacunae (arrow). Bone marrow (BM) is evident in the lower portion of the photomicrograph, indicating bone maturity.
