Abstract

The aim of this study was to compare the bone resorption rate and histometry of ChronOS, a beta-tricalcium phosphate (beta-TCP), mixed with autogenous bone grafts (1:1) with that of autogenous bone grafts alone in maxillary sinus elevation surgery. A total of 12 maxillary sinuses were grafted with an autogenous bone graft (control group) and 9 with ChronOS mixed with an autogenous bone graft (test group). Postoperative cone beam computed tomography (CBCT) was used to measure the initial graft volume after 15 days (T-1), and 6 months later another CBCT scan was performed to evaluate the final graft volume (T-2) and determine the graft resorption rate. The resorption outcomes were 45.7% +/- 18.6% in the control group and 38.3% +/- 16.6% in the test group (P = .17); the bone formation rate was 38.6% +/- 10.5% in the control group and 25.4% +/- 6.4% in the test group (P = .001). ChronOS mixed with autogenous bone graft demonstrated a resorption rate similar to that of the autogenous bone graft but with a difference in bone formation after 6 months. (AU)
