The authors have treated a squamous-cell carcinoma occurred in molar region of the right mandible in 52-year old woman by means of bony resection and banked tibial bone graft, and made the normal appearance of her face. The result as follow: 1) The healing of a graft is similar to the healing of an uninfected fracture except that it will take considerably longer. It is of the utmost importance that it should be well immobilized, otherwsie there is danger of absorption of bone and fibrous union. 2) Until the graft acquires a blood supply it is easily infected, for it has no defence against organisms, so it is most important to prevent wound infection set in.
