Influence of Mechanical Properties of Dental Implants on Biomechanical Behavior: A Three-Dimensional Finite Element Analysis

Abstract

In the context of this numerical study is particularly to analyze and observe the effect of mechanical properties and masticatory efforts on the intensity and distribution of biomechanical stresses induced in the mandibular bone (the cortical bone, the spongy bone) and in the elements which constitute the structure of the dental bridge (abutments, implants, bridge). The 3D model studied is subjected to loading in the three directions of space (corrono-apical, disto-medial, bucolingual). The numerical analysis allowed us to highlight the localization of the stress concentration zones, on the one hand, at the level of the regions of contact between the elements of the dental bridge structure and on the other hand, at the level of the mandibular bone. This parametric approach for the mechanical properties of bridges is used to better visualize and quantify the biomechanical behavior of dental bridges.
