Study By Finite Elements Of Stress Distribution by Comparing Behaviour Of 2 Types Of Composite

The Finite Element Method (FEM) is a standard method used to simulate the stress distribution in dental restorations. The aim of this study is to compare, given their mechanical properties, the behavior of the composite resin "Saremco ELS® " (Saremco ELS, Rebstein Switzerland) to that of the nano-hybrid composite resin "TetricEvoFlow® " (Ivoclar, Vivadent, USA) in filling a class V cavity on a lower central incisor using the finite element method. An incisive load of 250 N acting at an angle of 60 ° with the axis of the tooth was simulated in order to highlight the possible consequences on the behavior of the two restorations, the effects of different loads and loading angles were also studied.
