Abstract
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.
Claims12
An artificial denture prepared by disposing in the configuration of said artificial denture and then polymerizing at least one essentially pure compound of the formula ##STR5## wherein R is hydrogen of methyl, X is an ##STR6## or the -- SO.sub.2 -- group, Y is an oxyalkylene group of 2-5 carbon atoms or an alkylidene group of 2-3 carbon atoms.
