A dental restorative composition comprises a resin composition comprising a low shrinkage, polymerizable oligomer contains units of the structure: <?in-line-formulae description="In-line Formulae" end="lead"?>AB (I) <?in-line-formulae description="In-line Formulae" end="tail"?> wherein A is an organic radical having 1 to about 6 (meth)acrylate groups and 0 to about 5 hydroxy groups; B is an organic radical having 1 to about 5 epoxide groups, and wherein A and B are linked through the reaction of an epoxide and a hydroxy group; and a filler composition comprising a polyhedral silsequioxane and a sol-derived filler. These polymerizable dental composites may be used for a variety of dental materials, treatments, and restorative functions, including crown and bridge materials, fillings, adhesives, sealants, luting agents or cements, denture base materials, orthodontic materials and sealants, and other dental restorative materials.
