The fibular free flap (FFF) approach is the preferred option for reconstruction of segmental mandibular deficiencies. Fixed dental prostheses are recommended for patients who have undergone FFF jaw surgery to improve quality of life, but treatment of these patients with an implant-supported prosthesis is challenging because of the thin bone and thick soft tissue in the fibula. This case history reports the use of a bone-level implant guide fabricated with a computer-aided system and milled customized long abutments for implant placement and prosthodontic procedures. Advanced digital technologies can facilitate jaw rehabilitation in patients with bone flap.
