Surgical management of extensive tumors in the mandibular region leads to massive disfigurement of the face. Also the prosthetic outcome of such patients rehabilitated with free soft tissue flaps is very poor. Reconstruction of extensive defects to overcome the disfigurement is a challenging procedure and can be achieved with free fibula flap. Free fibula graft provides sufficient length of bone for the reconstruction of the postsurgical defects. Excellent vascularity of fibula flap allows for easy uptake of the graft and osseointegration of the dental implants. The addition of a skin island allows for absolute tension-free intraoral closure that enhances tongue mobility. Fibula graft allows proper tissue support after mandibular reconstruction. After rehabilitation with free fibula graft we can plan for prosthodontic rehabilitation with implant retained prosthesis leading to improved masticatory function. It also helps to improve speech outcome as a stable prosthesis can be delivered with the help of implants retained in the fibula graft. It is essential to assess the outcome of surgical reconstruction with fibula graft followed by prosthetic rehabilitation with implant retained prosthesis for their recognition as a treatment of preference. This article details the clinical report along with various clinical parameters for implant retained prosthetic rehabilitation of the patient who had undergone mandibular resection and reconstruction with free fibula graft.
