Abstract

Novel composite materials based on polymer matrix with inorganic filler have been synthesized and characterized in order to evaluate their potential application in dentistry, as restorative materials. Since the polymerization shrinkage (PS) that occurs in the matrix phase is one of the most commonly cited deficiencies of dental restorative composites, the present study investigated the reduction in volume upon curing. The shrinkage study involved buoyancy technique and the determination of the densities of selected materials. The conclusion assessed was that the investigated composite materials showed a better behavior, in comparison with literature findings on commercial employed dental composites
