N2 - Purpose: To analyze and compare the stress distribution in 3D FEA models of Implant supported mandibular crown in different densities of bone with platform switched abutment and another with a conventional matching diameter abutment. Material and Method: Eight finite element models of different densities of bone with conventional and platform switched implants were prepared and subjected to axial and oblique loading. Average von Mises stress values were evaluated quantitatively and qualitatively. Results: Maximum stress for the cortical bone were noticed in the D4 bone followed by D3,D2 and D1 bone. There was no significant difference between the stress values of cortical bone and cancellous bone Conclusion: Within limitation of this study greater stress was generated in cortical bone and in implant abutment complex in platform switched implants.
