Optimizing Dental Implant Model by Comparison of Three Dimensional Finite Element

The application of finite element ranging from biomedical engineering. Biomechanics is fundamental to any dental implant design. Strengths at any points in the construction are critical and govern failure of the prostheses, remoulding of bone and type of tooth movement. In our study Finite Element Analysis were performed to find out the best thread shape by comparing stress induced in cortical and cancellous bone. We have taken two different thread shape implant namely Implant A: Tapered cylindrical implant with alternate thread shape of triangular and Square. 2. Implant B: Tapered cylindrical implant with alternate thread shape of triangular andTrapezoidal. To investigate effect of stress induced in bone we carried out structural static analysis of Implant, cortical and cancellous bone assembly created in 3-D modelling application. After creating 3-D model imported that model in CAE application namely ANSYS for Static structural analysis. After comparing results of both implants we found that stresses induced in bone of Implant A is less as compared to Implant B. From this study we may conclude that it is first time we are using taper implant design to investigate the stress distribution inside the bone and it is observed that due to the tapered implant design and combination of thread shape stresses decreases in depth as where thread taper angle increases. As thread taper angle increases stress induced in bone is reduced.
