Biomechanical assessment of titanium, zirconia, and polyetheretherketone abutments under functional loads: A finite element study.
PURPOSE To compare the biomechanical behavior of titanium, zirconia, and polyetheretherketone (PEEK) abutments in implant-supported restorations under vertical and oblique loading using finite element analysis. METHODS Three three-dimensional models were created using SolidWorks software and analyzed using finite ele...
