The goal of this study is showing the effects of bone mass density and bone–implant interface characteristics onmaximum stress in mandible bone. A 3D nonlinear finite element analysis has been done on a planted titanium cylindrical implant with frictional contact of bone–implant interface. Considering the coulomb frictional contact, maximum Von Misses stress increases in cancellous bone, prominently. It has been shown that cortical bone stress is more sensitive to friction coefficient than cancellous bone. Bone mass density changes with variation of bone strain in specific spans of the strain. Raise of bone mass density in cortical bone increases the stress of cortical bone and decreases the stress of cancellous bone. Sensitivity analysis shows that cortical bonestress is 2.7 times more sensitive compared with cancellous bone.<\div>
