The use of dimethacrylate resin composite in dentistry involves the potential of shrinkage and then stress contraction. This leads in consequence to defects and even secondary caries. The aim of this study was to modify the commercial resin-based composite using selected monomers and to assess the influence of such additives on polymerization stress and bulk mechanical properties. The polymer matrix was modify due to implementation monomers with differentiated chemical constitution. Stresses generated by the filling were calculated on the basis of the theory of elasticity patterns. The depth of cure and microhardness was evaluated as well. On the basis of measurements, it has been found that stress could be reduced even up to a half when composite is chemical modified by adding not less than 0.25 wt % of 1,6-hexanediol dimethacrylate or diurethane dimethacrylate.
