Stress Analysis of an Endosseus Dental Implant by BEM and FEM [PDF]

The Open Mechanical Engineering Journal, 2012
In this work the Boundary Element Method (BEM) and the Finite Element Method (FEM) have been used for an elastic-static analysis of both a Branemark dental implant and a generic conic threaded implant, modelled either in the complete mandible or in a mandibular segment, under axial and lateral loading conditions. Two different hypotheses are considered
