Abstract Osseodensification is used to densify natural bone and increase dental implant stability. This work aims to compare, using finite element analysis, the stress generated on different jawbone areas between conventional drilling (OD) and osseodensification drilling (CD). Cone-beam CT scans of four different edentulous patients were obtained. Implant insertion and removal in the four bone models were simulated for the two different drilling techniques. Materials distribution was set as homogeneous throughout each part. In the OD technique, a new densified region was formed with new material properties based on a relation between density and elasticity. Material distribution of the densified regions was assumed to be a non-homogenous linear pattern and its gradual variation complies with the graph-related slope equations. Von-Mises stress for cortical and trabecular bone was significantly higher in the CD model in comparison to their values in the OD, as densified regions have absorbed most of the stresses and restricted their propagation. The same phenomenon was observed in the implant pull-out bone model. The OD technique was found to affect the primary stability of dental implants positively. The bone types present in different jawbone regions react differently to this technique according to the percentage of trabecular bone to cortical bone.
