This clinical report presents the multidisciplinary treatment approach for a 23-year-old male patient who underwent a total mandibular reconstruction due to trauma in the past and experienced postoperative complications. For his retreatment, exposed fixation plate was removed and infected bone was debrided and then a free fibula graft augmentation with simultaneous implant placement procedure was performed. After an osseointegration period of 6 months, a screw-retained porcelain fused to metal fixed prosthesis was fabricated and delivered.
