Abstract

In this study, the advantages of Porous Implants compared to conventional implants in order to apply a specific type of porosity to the implant most were investigated. The use of Triply Periodic Minimal Surface (TPMS) in Porous Implant design due to its curvature has a high potential in designing variable structures both morphologically and in relative density with respect to its implicit structural equations. The equations of Triply Periodic Minimal Surface are solved using the Grasshopper plugin, and finally the surface of a unit cell is obtained to design porous structure. One common dental implant and two porous dental implants with 54% and 65% porosity are modeled on Straumann's catalog according to ITI standard. In static and dynamic loading, forces were inserted into the implant in three different directions according to biomechanical principles. The results showed that after implantation of dental implants, the maximum amount of stress increased in the Porous Implants compared to the conventional implants so that it increased from 31. 82 to 98. 93 MPa in the fifth second. And in Porous Implants, stress distribution in the cancellous bone is increased compared to the conventional implant. Stress Shielding can be counteracted by porosity of dental implants. In this phenomenon, the implant, due to its much greater strength than the bone, prevents the transfer of stress to the bone, which results in weakening of the bone around the implant. By applying porosity and applying the TPMS to the implant. Stress distribution increase in the cancellous bone.
