Objectives Definition of implant success is unclear in prosthetic implant-based rehabilitation of head neck cancer patients. Materials and methods Fifty-two patients with 309 inserted implants were included in this prospective observational study. Implant survival (in situ and loaded) and implant success (modified Albrektsson criteria) at 2-year follow-up were evaluated under the influence of patient- and implant-specific variables. Results Thirty-nine patients with 234 implants finished the study. Overall implant survival after 2 years was 92.3% (216/234) with an osseointegration rate of 94% (220/234). Implant success was 78.6% (184/234). Main reasons for failure were "bone resorption > 1.7mm" (n = 27, 11.5%) and "implant not in situ or not loaded" (n = 18, 7.7%). Smoking (OR 3.1,p = 0.034), bone grafts (OR 2.4,p = 0.021) and radiation dose > 60 Gy (OR 3.8,p = 0.025) revealed as significant predictors for implant failure. Conclusion Implant survival differs significantly from implant success in head and neck cancer patients. Implant success is mainly determined by radiographic peri-implant bone resorption.
