Implant Installation With Ridge Augmentation Using Autogenous Bone Harvested From an Adjacent Site
In general, autogenous bone is the most predictable material of choice for augmentation procedure. However, the autogenous bone graft procedure requires an additional surgical wound, and the amount of graft is limited because of the donor site. In this case, autogenous corticocancellous bone cores were harvested adjacent to the implant surgical site and the defect, which was distal to the implant surface, was treated with autogenous bone and deproteinized bovine bone. The implant-supported prosthesis was functioning well up to 6 months without any probing depth or gingival inflammation.Abstract
Figure 1. Clinical photograph at the initial visit. The extraction socket showed insufficient healing. Figure 2. Two implants were placed in the lower left sextant with the insertion torque of 40 Ncm. There was a 5.5 mm (mesiodistal) × 6.0 mm (buccolingual) defect located distal to the most distant implant. Figure 3. Corticocancellous bone cores were achieved from the buccal shelf area using a trephine bur. The cores were then crushed into smaller particle sizes using a rongeur forceps and a bone mill. Figure 4. The autogenous bone was packed against the implant surface and the basal surface of the extraction socket, and the rest of the area was then filled with deproteinized bovine bone.
