IMPLANT REHABILITATION OF IRRADIATED JAWS - A PRELIMINARY-REPORT

Ten patients (3 maxilla, 7 mandible), who had been treated for a head and neck malignancy by undergoing radiotherapy, had 42 implants (10 ma xillary, 32 mandibular) placed into the irradiated sites and either an overdenture or a fixed prosthesis fabricated. Of the 10 implants plac ed in the maxilla, 6 were lost; however, there was a 100% survival rat e of the implants placed in the mandible (mean duration = 33 months). The use of longer implants and pre-or postimplant hyperbaric oxygen ma y be necessary in maxillary situations.
