I also had a mandibulectomy with fibula rebuild at Mayo Ariz. My surgery and recovery went well and I am now trying to make my way through trying to get implants for a denture. I am told by many drs that is is very risky since Id had radiation a year ago. otherwise the fibula is supposed to be able to accept implants just fine. but blood flow to the new mandible is difficult after radiation so it is very risky. They are proceeding slowly, one at a time and watch and see. they are afraid of osteoradionecrosis.
