Three-dimensional finite element analysis of three internal tapered implant-abutment designs

ABSTRACT Objective: The aim of this study was to compare the stress distribution in internal tapered connection implants with different adaptation geometries submitted oblique load simulation using Finite Element Analysis (FEA) method. Methods: Three implant-abutment assemblies were modeled by varying only diameter abutment body cone region. dimensions 4.0 mm and 13 length. Oblique loads 210 N angled 30 degrees long axis implant applied a hemispherical positioned over abutments simulating dental crown. generated assembly analyzed FEA method von Mises criterion. Results: A higher concentration coronal region (collar) on opposite side application shown, as well screw threads. cervical showed highest values, values being observed G3 (1034 MPa), followed G2 (841 MPa) G1 (702 MPa). Conclusion: According results presented, it can be concluded that more homogeneous less concentrated assembly. Therefore, use standardized manufacturer is recommended.
