چکیده
this case report presents a combination of surgical and prosthetic solutions applied to a case of oral implant rehabilitation in post-oncologic reconstructed mandible. bone resection due to surgical treatment of large mandibular neoplasm can cause long-span defects. currently, mandibular fibula free flap graft is widely considered as a reliable technique for restoring this kind of defect. it restores the continuity of removed segment and re-establishes the contour of the lower jaw. however, the limited height of grafted fibula does not allow the insertion of regular length implants, therefore favouring vertical distraction osteogenesis as an important treatment choice. this report presents a patient affected by extensive mandibular ameloblastoma who underwent surgical reconstruction by fibula free flap because of partial mandibular resection. guided distraction osteoneogenesis technique was applied to grafted bone, in order to obtain adequate bone height and to realize a prosthetically guided placement of 8 fixtures. after osseointegration, the patient was rehabilitated with a full arch, screw-retained prosthetic restoration. at five-years follow up, excellent integration of grafted tissue, steady levels of bone around the fixtures and healthy peri-implant tissues were reported. key words: ameloblastoma, dental implants, distraction, osteogenesis

متن کاملVertical distraction osteogenesis of a free vascularized fibula flap in a reconstructed hemimandible for mandibular reconstruction and optimization of the implant prosthetic rehabilitation. Report of a case.
Free vascularized fibular flap is considered the treatment of choice in mandibular reconstruction for extensive bone defects (over 6 centimeters) resulting from trauma, infections or tumor resections. But, when the reconstruction involves a dentate mandible, the fibula has the limit as it does not offer sufficient bone height to restore the alveolar arch up to the occlusal plane. Therefore, the...
متن کاملCorrection of a mandibular asymmetry after fibula reconstruction using a custom-made polyetheretherketone (PEEK) onlay after implant supported occlusal rehabilitation.
This study describes an unusual case of mandibular asymmetry after fibula free flap reconstruction in a young man following major facial trauma that was corrected using a custom-made polyetheretherketone prosthesis. There is little information in the literature on the use of alloplasts to correct mandibular asymmetry as interest in 'aesthetic re-modelling' has traditionally focused on nasal, zy...
