Methods: Following potential prognostic factors for implant survival were analyzed: bony bed (local bone versus augmented iliac crest bone), radiation dose (no radiation, <50 Gy, ≥50 Gy) and implant dimensions. Kaplan-Meier survival estimates of the inserted implants were performed. Results: After 5 years, the cumulative survival rate of all investigated implants was 82.6%. Dental implantation into augmented bone resulted in a significantly lower survival rate (78.4%), compared to original local bone (92.8%).
