In restorative dentistry it is common practice to replace amalgams with resin based dental composites, with minimal or no additional cavity preparation. Polymerization shrinkage of dental composites causes stress, whose influence is transferred to tooth tissue which may result in the
occurrence of micro-cracks and post-operative pain. The aim of this study is to determine the effects of different cavity shapes on stress and strain distribution which occurred due to composite shrinkage. Toward this aim, experimental (Digital Image Correlation method – DIC) and numerical (finite element method – FEM) techniques are used. The numerical model is verified by comparing its results with those obtained by experimental methods. Upon verification, the 3D model of the cavity is modified to develop two new models with the same tooth geometry, but different cavity shapes, in order to determine the effect of their shapes on stress distribution. It is determined that the thickness of dentine around ...the cavity plays a significant role in stress and strain distribution
