Abstract
The use of dental implants in reconstructed bone surgery after osteotomy has recently increased because of difficulty achieving stability with dentures. However, when placing implants in a reconstructed bone, ideal positioning of the implant and control of orientation are problematic because the bone structure and morphology differ significantly from that of the normal jawbone. We report a case in which long-term stability was achieved after implant treatment using a guided surgery technique. The patient was a 46-year-old man who had undergone segmental mandibulectomy for ameloblastoma and jaw reconstruction with a free iliac bone graft. The patient complained of chewing difficulties despite occlusal reconstruction with dentures. Guided implant placement was performed, and a prosthesis was successfully fabricated, achieving good esthetic and functional results. Eight years after prosthesis placement, no signs of tumor recurrence have been seen, and the implant remains in good condition.
