In this paper the mechanical behaviour of an endodontic implant, based on a new restoration technique, is analyzed.

In order to analyze the statical behaviour of the restoration, three-dimensional nonlinear large-displacement finite-element analyses are performed for several load conditions, both in the case of a double-post restoration and of a single-post one, highlighting the advantages of the new proposed technique.

Abstract

In this paper the mechanical behaviour of an endodontic implant, based on a new restoration technique, is analyzed. It employs multiple prefabricated posts instead of one post in such a way that the root cavity may be more efficiently filled. From a statical point of view, the use of multiple posts enables an increase of the overall mechanical resistance of the implant. Moreover, as a consequence of the global core-post interfaces increasing, a reduction of the interface shear stress, leading to a reduction of the post pull-out risk, is expected. In order to analyze the statical behaviour of the restoration, three-dimensional nonlinear large-displacement finite-element analyses are performed for several load conditions, both in the case of a double-post restoration and of a single-post one, highlighting the advantages of the new proposed technique.
