Effect of Implant Diameter and Length on Stress Distribution for Titanium and Zirconia Implants by Using Finite Element Analysis (FEA)

Abstract

Purpose: The purpose of this study was to analyze stress distribution patterns in implant restorations created in different length and diameter made of titanium and zirconia by using three dimensional finite element analysis (FEM) with straight and 15˚ angled abutment. Materials and Methods: For titanium models; Ti-6Al-4V for implant fixture, connection element and abutments (straight and 15˚ angled abutment), yttrium tetragonal zirconium polycrystal (Y-TZP) for zirconium framework, Felds phatic porcelain for superstructure material and for zirconia models; Y-TZP for implant fixture, connection element, abutments (straight and 15˚ angled abutment) and zirconium framework, Felds phatic porcelain for superstructure material were used. The implants and their superstructures were modeled using CAD software Creo Elements-Pro5.0 and the mandibula was modeled using MIMICS 13.1 software.
