Comparative three-dimensional finite element analysis of implant-supported fixed complete arch mandibular prostheses in two materials.

Background: The increase of requests for implant-supported prosthesis (ISP) with zirconia as infrastructure has attracted a lot of attention due to its esthetics, biocompatibility, and survival rate similar to metallic infrastructure. The aim of this study was to evaluate the influence of two different framework materials on stress distribution over a bone tissue-simulating material.

Materials And Methods: Two ISP were modeled and divided into two infrastructure materials: titanium (Ti) and zirconia.
