Minimization of polymerization shrinkage effects on composite resins by the control of irradiance during the photoactivation process
2018
High levels of shrinkage stress caused by volumetric variations during the activation process are one of the main problems in the practical application of composite resins.
Objective
The aim of this study is to reduce the shrinkage stress and minimize the effects caused by composite resin volumetric variation due to the photopolymerization. In this way, this work proposes a systematic study to determine the optimal dimming function to be applied to light curing processes.
