BONE ALLOGRAFTS IN PERIODONTAL THERAPY

Bone allografts as used in dentistry have a 20-year history of safety and efficacy, Case reports and controlled clinical trials have shown t he potential of both mineralized and decalcified cortical freeze-dried bone allograft to reconstruct the bone defects caused by periodontiti s, Histomorphometric analysis of human biopsies following grafts of de calcified freeze-dried bone allograft have shown the ability of decalc ified freeze-dried bone allograft to promote regeneration of new bone, cementum, and periodontal ligament an a tooth root surface previously exposed to bacterial plaque, The addition of mineralized freeze-dried bone allograft and decalcified freeze-dried bone allograft to the gui ded tissue and guided bone regeneration procedures have significantly enhanced results, especially in large osseous lesions.
