Allogeneic Bone Block Volume Preservation in Ridge Augmentation for Implants

摘要

Allogeneic bone blocks are commonly used for bone augmentation in implant dentistry. Allogeneic bone blocks have the advantage of containing growth factors and the original human scaffold. A major disadvantage is the risk of substantial graft volume decrease due to resorption. The purpose of this study was to evaluate whether corticocancellous allogeneic bone blocks can predictably maintain graft volume to allow implant placement and esthetic restoration. A total of 141 allogeneic bone blocks were placed in 117 patients, allowing for 183 implants. The implant success rate was 96.7% after 6 to 96 months of follow-up.
