Finite element stress analysis of dental prostheses supported by straight and angled implants.

Purpose: A three-dimensional finite element analysis was conducted to evaluate and compare the stress distribution around two prosthesis-implant systems, in which implants were arranged in either a straight-line or an intrabone offset configuration.

Materials And Methods: The systems were modeled with three titanium implants placed in the posterior mandible following a straight line along the bone. The straight system was built with three straight implants (no offset).

Comparative 3D finite element stress analysis of straight and angled wedge-shaped implant designs.

Purpose: The goal of this work was to analyze the stress distribution in 2 wedge-shaped implant designs, straight and angled, by means of a 3-dimensional finite element method (FEM) stress analysis.

Materials And Methods: A model was generated from computerized tomography of a human edentulous mandible with the implants placed in the left first molar region. The model included boundary conditions representing the muscles of mastication and the temporomandibular joint.

Finite element stress analysis of cuneiform and cylindrical threaded implant geometries.

Statement of problem. Different implant geometries present different biomechanical behaviors and in this context, one arising question is how cuneiform implant geometry compares to clinical successful cylindrical threaded implant geometry. Purpose.

Three-dimensional finite element stress analysis of a cuneiform-geometry implant.

Purpose: The biomechanical behavior of an osseointegrated dental implant plays an important role in its functional longevity inside the bone. Studies of this aspect of dental implants by the finite element method are ongoing. In the present study, a cuneiform-geometry implant was considered with a 3-dimensional model that had a mesh that was finer than in the models commonly found in the literature.
