Three-dimensional finite element models of implant-supported fixed prostheses were created using six framework materials and four veneering types, forming ten groups in total. After meshing bone and restorative structures, material properties (Poisson\u2019s ratio and Young\u2019s modulus) were assigned. A 178 N load was applied vertically and at 45\u00b0 to the palatal surfaces of the maxillary central incisor and canine, and von Mises and tensile stresses were analyzed in the implants, abutments, peri-implant bone, and superstructures.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>Under both loading conditions, the highest stresses occurred in the polyetheretherketone (PEEK) (implants, abutments) and fiber-reinforced composite (FRC) (superstructures) groups, while the lowest were found in the monolithic zirconia group. In cortical bone, stress was highest in the FRC group under oblique loading and in the PEEK group under vertical loading, whereas the Co-Cr group showed the lowest abutment stress under oblique loading.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The study demonstrated that different framework materials significantly affect stress distribution within the implant, abutment, peri-implant bone, and prosthetic superstructure.
