Abstract
Twenty-five implants were placed in 6 himimaxillectomy patients. After 11 to 79 months of follow-up, 2 of 25 implants were removed and 4 were buried. Sixty-seven implants were placed in vascularized bone grafts of 16 patients. After 9 to 69 months of follow-up, no implants were removed and 6 of 48 implants placed simultaneously with bone grafts were buried. In a multicenter study, 228 implants placed in irradiated tissues of 44 patients were evaluated. Of 228 implants, 59 were placed in the maxilla, and 169 were placed in the mandible.
Seventeen of 59 implants placed in the maxilla were removed ; and 3 of 169 were removed from the mandible.
