Abstract	Dental implants have a great role in changing treatment concepts to edentulous ridges. This paper presents a finite element analysis evaluation of the effect of implant design on the stress distribution induced in bone surrounding the implant and on the micro displacement of the implant of a full arch screw retained cantilevered fixed mandibular restoration, in case of immediate loading. Twelve models were simulated, all composed of four identical interforaminal dental implants and a cantilever overdenture. Two design parameters (the implant diameter and taper) were tested while keeping all other parameters fixed. The simulated 12 implants have 3. 2, 3. 7, 4. 7 and 6 mm diameter with 0, 2 and 5 degrees tapering respectively. Vertical and oblique loads were applied on the right premolar and first molar under model restrain. Results revealed that, increasing implant diameter leads to decreased bone induced stresses and also decreased implant micro displacement and so leading to better initial stability. On the contrary, increasing implant tapering increased bone induced stresses and also increased implant micro displacement.
