A three-dimensional finite element analysis of mandibular overdenture supported by cylindrical and conical implants
This 3D finite element study assessed the stress distribution in mandibular overdenture supported by the 3i Locator system attached to two cylindrical or conical implants placed at the canine region. A 100 N vertical load was applied over the right first molar of the two overdenture models. The von Mises stresses were concentrated at the cervical and middle implant thirds. Cylindrical implants showed larger crestal bone area of high stresses in comparison to the conical implants. The results suggest that conical implants reduce the stresses in peri-implant crestal bone at both loading and non-loading sides.
