Abstract

2d and 3d modelling comparison for a human first premolar to determine an appropriate cavity filling material B. Ekici, E. Giingor, M. Akyiiz & S. Altintas Bogazigi University, Istanbul, Turkey ABSTRACT A finite element Technique is used to examine the stress distribution in a human first premolar with and without cavity preparetion by using 2- dimensional and 3-dimensional models. The effects of different materials as cavity fillers on stress distribution are investigated. The effects of spring support conditions and temperature are also considered in the study. The finite element method, an often used engineering technique, is well suited for application to the dental stress analysis. 2D and 3D stress distribution have been investigated for a specific cavity design and for an inclined load conditions. Cavity preparation to first premolar causes high principal stress concentration as expec
