Lebanonphoto_auteurInfluence of material and connector size on the stress distribution of a temporary bridge: a finite element analysis

C. Rouhana, P. Habre - Lebanon
Published in French in Tropical Dental Journal N° 169 - Volume 43 - Mars 2020 - 5-16


Introduction: The aim of this study was to evaluate, with the Finite Element Analysis (FEA), the influence of the material and the connector size on stresses in a 3-unit temporary fixed partial denture in order to estimate the fracture resistance.
Materials and methods: Nine three-dimensional models were then constructed with three different temporary materials: a self-cured acrylic resin (Unifast III), a self-cured composite resin (Luxacrown) and a CAD/CAM PMMA-based polymers (TelioCAD) and three different cross sectional sizes of the connector: 9, 12 and 16 mm2. An axial force of 500 N was simulated onto the pontic. The distribution of the equivalent Von Mises stresses was computed for each model using the software ANSYS Workbench 19.1 (Ansys Inc., USA). The data were statistically analysed ...
