Effect of Screw Profile on Stress Distribution Pattern of Dental Implants by FEA

ARTICLE INFO Dental implants constitute a well-established approach for substitute of lost teeth with titanium being the most preferential material for implantation. However, titanium has its confines in esthetically demanding cases and neither the form nor material of such implants has changed much over the past 40 years. Immediate implantation is used to overcome the disadvantages of conventional implantation which in turn has many disadvantages owing to the incongruence of the implant to the extraction socket. The commonly used method for testing of new implant prosthesis is in vitro which involves direct involvement of human. But use of modern techniques can help one decide the diameter and screw thread profile. In finite element analysis the domain is divided in number of small elements. In finite element analysis one can also simulate different material models and analyze the actual working conditions. In this project work the size of the implant is selected. A 3-D CAD model is modeled with appropriate CAD software. A finite element model is created representing the bone and dental implant. The result obtained from finite element analysis shows the stresses and deformation at the contact locations of bone and implant. By varying the diameters and screw profiles one can come to conclusion of the optimum design of the implant prosthesis. Keywords— Dental implant, Optimum, FEA.
