Analysis of Composite Shrinkage Stresses on 3D Premolar Models with Different Cavity Design using Finite Element Method
(Trans Tech Publications Ltd, Durnten-Zurich, 2014)
Local polymerization stress occurs due to polymerization shrinkage of resin based composites adhesively bonded to tooth tissues. Shrinkage causes local displacements of cavity walls, with possible occurrence of micro-cracks ...
