All materials were assumed isotropic, homogeneous, and linearly elastic. A 100\u00a0N oblique load at 45\u00b0 was applied to the palatal region of the maxillary anterior teeth in a labio\u2010apical direction to simulate anterior functional loading. Maximum principal stress, minimum principal stress, and von Mises stress were evaluated in the supporting bone, implant body, fixation screws, and prosthetic bar.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Maximum and minimum principal stress values in the supporting bone progressively increased with cantilever length, with minimal material\u2010related differences.

Prosthetic bar von Mises stress values peaked at 2\u00a0mm.
