Reconstruction of the resorbed edentulous maxilla using autogenous rib grafts and osseointegrated implants.

Abstract

14 patients with severely resorbed edentulous maxillae underwent reconstruction by the use of autogenous rib graft on-lays and osseointegrated Brånemark System implants in a one-stage procedure. 75 implants were installed. 16 (21.3%) failed to osseointegrate at the abutment connection. After a mean observation period of 5.2 years, 55 (73.3%) of the original implants were osseointegrated. 10 supplementary implants were inserted in 3 patients. At the end of the observation periods, 2 patients had overdentures and 12 had fixed prostheses. The mean marginal bone loss was 2.13 mm (SD 0.47 mm) the 1st year after grafting, and 2.92 mm (SD 1.27 mm) at the end of the follow-up periods. Long-term follow-up did not show any persistent donor site discomfort. The results indicate that this technique is a conceivable alternative for patients with severe maxillary resorption.
