A low shrinkage, polymerizable oligomer comprises units of the structure: AB (I) wherein A is an organic radical comprising 1 to about 6 (meth)acrylate groups and 0 to about 5 hydroxy groups; B is an organic radical comprising 1 to about 5 epoxide groups, and wherein A and B are linked through the reaction of an epoxide and a hydroxy group. In one embodiment, a dental restorative material comprises the low shrinkage, polymerizable dental oligomer, a filler system, and a curing system. These polymerizable dental resins 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.
