Maxillofacial surgery deals with major surgery of jaw bone tumour, oral cancers, temporomandibular joint, congenital facial defects, jaw bone fracture etc. This branch of surgery has come up more recently with advanced surgical technique and bone grafting has become a regular job for maxillofacial surgeons in the reconstruction of acquired or congenital jaw defect. The term grafts applies to the transplantation of living tissues and implant means transplantation of nonviable tissues. Besides microvascular flap with bone may be grafted anastomosing with vessels. Numerous attempts have been made for long time to employ these procedures in the reconstruction of jaw after oncological surgery, destruction of a bone by accident, congenital defects, in the treatment of jaw deformity, TM joint abnormalities. Various types of bone grafts, such as- xenogenic bone grafts, autogenic bone grafts, allogenic bone have been successfully transplanted time to time by some authors. However the success of bone grafting is still a challenging issue in the maxillofacial surgery.
