Abstract

Based on ESPI experimental principle and finite element theory, this research obtains the law that the shrink of light-cured composite resin leads to deformation. The out-of-plane displacement of light-cured composite is measured by ESPI experimental system, and then the model corresponding to the test that is built in ANSYS and numerical simulation are building, so that solidified deformation and stress of light-cured composite is studied. These results are compared with each other and the differences between the results are small. It is found that ESPI is a feasible testing method which is suitable to deformation measurement of structure surface. Influence factors of drawdown deformation of composite resin are obtained by ESPI experiment and numerical calculation, some basis is provided for clinical treatment, and direction that improve the performance of light-cured composite resin are provided for manufacturer of this resin.
