The effects of implant length and screw pitch on the stress and strain distributions were analyzed in terms of bonded and contact bone-implant interfaces. The influences of the contact parameters, contact stiffness and friction coefficient, of the model were evaluated. The results show the differences on the stress distributions at the bone-implant interface in the models with different implant lengths and thread pitches. The highest stress in the model with contact interface is higher than that in the bonded model.
