Abstract

Background: In this study, we present medium- and long-term data on implant survival in a cohort of patients with severe maxillary atrophy rehabilitated using reconstructive implant site development with calvarial bone grafts. Materials and Methods: We obtained clinical records from patients treated with implant rehabilitation supported by calvaria bone grafts in the Oral Surgery Department of IRCSS San Raffaele (Milan, Italy). Implant and prosthetic survival and success rates were retrospectively evaluated. Graft survival and postoperative complications were also assessed. Results: A total of 207 implants placed in 32 patients were evaluated for a mean period of 10.0 years from loading. After 10 years, the cumulative survival rate was 97.10%, the implant success rate was 92.75%, and the prosthetic complication rate was 9.76%. A graft survival percentage of 96.88% was observed, and postoperative complications occurred in 28.13% of cases. Conclusions: The 10-year survival rate and prosthetic complications for patients treated with implant rehabilitation supported by calvarial bone grafts are excellent, as implant loss was relatively rare, although limited subjects were available for the 10-year follow-up.
