Background–  The reconstruction of the mandible is a complex procedure because various cosmetic as well as functional challenges must be addressed, including mastication and oral competence. Many surgical techniques have been described to address these challenges, including non–vascularized bone grafts, vascularized bone grafts, and approaches related to tissue engineering.

Materials and Methods– this is a prospective study in which  the free vascularized fibula graft is used for reconstruction of various mandibular defects for benign and malignant conditions over a period of 2 years.

Observation– All the patients had good functional and cosmetic outcome

Conclusion– To conclude, the free fibula bone graft can currently be regarded as the "gold standard" for mandibular reconstruction in case of composite (inside and outside) oral cavity defects as well as a way of enabling the performance of one–stage dental implantation.
