A parametric finite element analysis study of the stresses in an endosseous implant.
The finite element analysis method was used to obtain the stresses in the various structures in an endosseous implant-contiguous bone construct using a two-dimensional idealization. The results were obtained as a function of the materials used for the post and the crown of the implant. It is shown that these stresses are critically dependent on the post material (for a given crown material). The clinical significance of the results is discussed.
