Finite Element Analysis Of Mechanical Behaviour Of Dental Materials

This work investigates the stress distribution of endodontically treated dental post and core of a central maxillary incisor. Three different cases are simulated through a 3D finite element analysis method — a.) Post and core both are made from titanium and are a single unit, b.) Post and core are made from titanium but are two different parts and c.) Post is made from titanium and core with epoxy resin. Different loading conditions and model shapes are considered to understand the stress distributions. The post experiences slightly higher stress when the resin core (case c) has been used but the dentin is less stressed than the other cases. The root anatomy seems to affect the stress distributions.
