Fresh frozen homologous bone in oral surgery: case reports

Intraoral bone defects may be treated using autologous grafts, homologous grafts, heterologous grafts or synthetic products. Autologous bone is now considered the gold standard for bone grafting procedures. Homologous fresh frozen bone, provided by bone banks, is frequently utilized by orthopaedic surgeons because it is considered a safe material from immunological and viral points of view. In the cases reported here, homologous bone was used to repair some osseous defects without changing the surgical protocol utilized for autologous bone procedures. The main advantages of this strategy are low morbidity, shorter surgical times, more comfort and less risk of infection for the patient as well as the greater availability of bone.
