Abstract

The dependence of polymerization contraction force development on irradiation for polymer composites was investigated. Contraction force during polymerization was measured with a low compliance test fixture. Contraction force was found to increase most rapidly immediately following light activation. Findings suggest that polymerization contraction force rate was linearly related to irradiance.
