The rehabilitation of patients affected by defects of the jaws after tumor resection is still very challenging. Resection can lead to significant facial deformity, impaired oral functions such as speech, swallowing, saliva retention, and concomitant psychological problems. Moreover, the loss of teeth and the alveolar and basal jawbone can lead to significant impairment of mastication. The reconstruction of such defects with autogenous bone grafts or revascularized free flaps has become a valuable means for the rehabilitation of these patients. Major benefits of such procedure include an usually low morbidity of the donor site and an extensive length of the bone graft. Moreover, vascularized grafts provide a good bulk of bone in which to place implants and a satisfactory contour. In fact, after reconstruction, local hard and soft tissue conditions often exclude the integration of conventional dentures because of the impairment of dental prosthetic retention by thin cutaneous tissue, the thickness of subcutaneous tissues, the absence of a perilingual and vestibular groove, and the fragility of soft tissues. In Literature it has been well established the high biologic value of vascularized fibula grafts regarding the potential of implant osseointegration, which seemed to be equal to regional mandibular or maxillary bone and eventually capable to provide sufficient stabilization of prosthesis.
