A finite element survey of eleven endosseous implants.

Eleven different post-type endosseous implants were biomechanically analyzed by use of the finite element method to compile a list of features that could be used to design an optimal post-type endosseous implant. Stress magnitudes and contours within each implant and within the surrounding bone were calculated. Implant features causing high stresses and low stresses, possibly contributing to pathologic bone resorption and bone atrophy were noted. Although this preliminary survey was not complete, tentative suggestions in implant design for improved implant performance were made.
