Experimental Analysis of Polymerization Shrinkage of Dental Restoration Material in Cavities

Abstract:

Article Preview

The polymerization shrinkage of light-cured composite resin, a dental restoration material, was studied using three different experimental methods. Digital image correlation method was used to examine the shrinkage deformation on the free surface of artificial cylindrical cavities. X-ray CT images and the digital image correlation were employed to measure the shrinkage deformation in the cavities. The shrinkage force was measured at the floor of the cavity using a load-cell, and evaluated as functions of time and the depth of the cavity.
