2D-Finite element analysis of inlay-, onlay bridges with using various materials
Journal Title: Archives of Materials Science and Engineering - Year 2016, Vol 79, Issue 2
Abstract
Purpose: To compare the impact of different bridge constructions and different loads onstress distribution in bridges.Design/methodology/approach: The study was conducted on 96 computer models ofboth premolars and molars that simulated a missing second premolar restored with a bridgesupported on crown inlays or onlays. Simulations were made of a bridge constructed fromfour different materials: Au alloy, Cr/Ni alloy as well as two kinds of glass fibre-reinforcedcomposites: Targis Vectris and FibreKor /Sculpture. The study was conducted using thefinite element method (FEM). The results were analysed with PQStat statistical softwareversion 1.6.Findings: In none of the analysed cases did stresses appear capable of damaging thebridge construction. Reduced stresses were lower in glass fibre reinforced compositematerials than in metal alloys.Practical implications: The force application point has a decisive influence on stressdistribution in the hard dental tissue and in bridges. The highest stress values occurred atthe loading of the pontic tooth.Originality/value: The force application point has a decisive influence on stress distributionin the hard dental tissue and in bridges. The highest stress values occurred at the loadingof the pontic tooth.
