The autoclaved autogenous bone graft as a re-implant. Results of animal experiments

The use of autoclaved bone grafts was studied in animal experiments. First we checked the immunological response in inbred rats. No antigen-antibody reaction could be detected after syngenic and allogenic autoclaved bone grafting. The bone healing of autogenous autoclaved rib grafts of different length was tested in inbred dogs. After polychrome sequential marking we investigated the periosteal and endosteal osteogenic repair of the transplant-area using different histological techniques. Simultaneously we observed the slow destruction and lysis of the autoclaved graft. In our opinion the use of autoclaved autogenous bone graft is possible, under stable conditions, for immediate reconstruction of the mandible in tumour surgery.
