Three models-glass fiber post, SFRC post, and ribbond fiber post \u2013 were analyzed with 4-mm gutta-percha seal. Material properties were assigned from the literature and a 100 N oblique load at 45\u00b0 was applied. Stress distribution was evaluated using von Mises criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>All postsystems showed similar deformation (\u22480.1428 mm). Internal stresses within post were 12.28 MPa (Glass Fiber), 5.22 MPa (SFRC), and 9.73 MPa (Ribbond). Cervical stresses were 5.21, 5.15, and 5.20 MPa, and stresses at the post end were 3.61, 1.49, and 1.95 MPa. Maximum stress occurred cervically, with SFRC post showing lowest stresses.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
