    摘要: Superior artificial teeth, dentures, other dental replacement parts and dental prosthetic articles and devices, which exhibit high abrasion resistance, stability to moisture and which do not undergo volume changes, are obtained by polymerization of a compound of the formula ##STR1## in which R is H or -CH.sub.3, X is an alkylidene or the -SO.sub.2 -group, Y is an oxyalkylene group having between 2 and 5 carbon atoms, or an alkylidene group having between 1 and 5 carbon atoms. In some instances, the polymerization is carried out in the presence of a filler.
