The main purpose of this research was to measure the resistance of insertion of a dental implant screw designed based on norm, made of the alloy Ti6Al4V [1], which was designed for the cancellous bone density (BD) molar region of the human jaw. The implants were embedded in the in a simulated bone polymer (Sawbone®) [2] and were compared with specimens of the region molar of human jaw cadaver [3]. Using a digital torque wrench, the values of the insertion torque (IT) were calculated in the specimens with the implants inserted [4]. The minimum measured value was 25 Ncm or 0.25 Nm and the density of the maximum torque value measured was 110 Ncm or 1.1 in Nm recorded in the cadaver jawbone. The Pull Out Test (POT) was then carried out in order to determine the resistance of the insertion implant at the bone interface. The experimental results obtained for density, IT and resistance to insertion were then compared in order to determine the strength of fixation of the implant to the bone interface.
