Patent ID: 7674850

Claim:
A dental product comprising a hardenable composition, wherein the hardenable composition comprises: a resin system comprising a crystalline resin component; greater than 60 wt-% of a filler system; and an initiator system; wherein the hardenable composition is in the form of a hardenable self-supporting structure having a first shape and sufficient malleability to be formed into a second shape at a temperature of about 15° C. to 38° C.; and wherein the crystalline resin component is a polymeric material having crystallizable pendant moieties and the following general formula: wherein R is hydrogen or a (C 1 -C 4 )alkyl group, X is —CH 2 —, —C(O)O—, —O—C(O)—, —C(O)—NH—, —HN—C(O)—, —O—, —NH—, —O—C(O)—NH—, —HN—C(O)—O—, —HN—C(O)—NH—, or —Si(CH 3 ) 2 —, m is the number of repeating units in the polymer, and n is great enough to provide sufficient side chain length and conformation to form polymers containing crystalline domains or regions; with the proviso that if the filler system comprises fibers, the fibers are present in an amount of less than 20 wt-%, based on the total weight of the composition.
