Abstract This prospective study was carried out to compare the survival of dental implants in irradiated and non-irradiated patients with maxillectomy defects. Sixteen patients (10 males and 6 females) were selected having at least three missing teeth in the intact portion of the remaining alveolar ridge after maxillary resection. The selected patients were divided into two groups; group 1 (non-irradiated) and group 2 (irradiated). Following careful diagnosis and treatment planning, all patients of both groups received three dental implants on the first stage surgery. On the same day, primary implant stability was measured using OSTELL device and implant bone level was recorded radiographically using paralleling technique and a preformed radiographic stent. Implants were left submerged for six months and during this period obturators were totally relieved at the site of implants to minimize trauma. Both groups were clinically observed for any signs of early failure while only (group 2) was observed for the onset of any signs of osteoradionecrosis |
