Abstract
Objective: The aim of this study was to analyze long-term implant survival in the mandible after radiotherapy and radical surgery in oral cancer patients.
Study design: Between 1990 and 2003, 71 patients (15 females, 56 males; average age 57.8 years, range 16–84.1 years) were treated with dental implants after radiochemotherapy and ablative surgery of oral cancer. Radiation therapy was delivered in daily fractions of 2Gy
given on 25 days (total dose of 50Gy). Oral defects were reconstructed microsurgically with jejunal, iliac crest or radial forearm grafts. Thereafter 316 dental implants were placed in the non-irradiated residual bone (84; 27%), irradiated residual bone (154; 49%) or grafted
bone (78; 25%) at various intervals (mean interval 1.41 .....................................
