Statement of Problem: Prediction of primary implant stability is important before surgery to determine the possibility of immediate loading.
Purpose: To evaluate the predictability of primary implant stability from cortical bone thickness and bone density values of cone bone beam computed tomography (CBCT).
Material and Methods: 10 completely and partially edentulous patients were
thickness and bone density, was investigated using Pearson's correlation and multiple regression analysis.
Results: The regression model accounted for 61.5% of the variations in the implant stability with an insignificant impact (p value=014). Age was found to be the only variable that has a significant impact on implant stability with a coefficient correlation of – 0.47 and a p value of 0.03. Conclusions: Within the limitations of this study neither cortical bone thickness nor bone density obtained from a CBCT can predict primary implant stability. On the contrary, age seems to have a significant impact on the primary implant stability.
Clinical implications: CBCT does not seem to be a valuable tool for predicting the primary implant stability. Bone density and thickness readings should be interpreted with cautions.
