(B) Panoramic radiograph just behind the reconstructive surgery site. (C) When the fixed wire of the left mandible was removed, complete resorption of the PLLA mesh tray and hard regenerated cortical bone was checked. (D) Vestibular extension using a full-thickness skin graft and three dental implant placements. (E) Bone maturity was checked on a panoramic radiograph 13 years postoperatively. (F) A satisfactory symmetrical mentum arch was observed with computed tomography 13 years postoperatively.
