Finite Element Stress Analysis of PEEK, Glass Fiber and Zirconia Post-Core Sys-tems in Maxillary Central Incisor

Objective: This study aims to analyze structural strength features (such as deformation and stress distributions) of polyether ether ketone (PEEK), glass fiber zirconia post-core systems utilized in maxillary central incisor roots by means finite element analysis (FEA).
 Material Method: The main geometry considered this was obtained using an intraoral scanner. Other sub-components were modelled a parametric computer aided design software based on the data from literature. Glass fiber, PEEK defined post materials. 100 N force applied with 45° angle palatal surface veneered tooth FEA set up. solved linear material model static loading assumptions through commercial code. Visuals numerical results related equivalent (Von Mises) distributions interpreted.
 Results: Maximum value 32.76 MPa calculated at post-core. maximum values for posts 0.80 21.17 MPa, respectively. 72.79 69.01 58.22 respectively.
 Conclusion: magnitude experienced post-cores root lower than post. Regarding this, although, it may be concluded that reduce complications require extraction clinical practice, further researches are suggested including trials.
