Dental composition, product and process using a silicon containing abrasion resistant material. The dental products formed are abrasion resistant and self-lubricating across their entire cross sections. Dental compositions useful for forming dental products in accordance with the invention preferably includes an ethylenically unsaturated silane. The composition is formed into a dental prosthesis, such as an artificial tooth, inlay, onlay, facing, crown or bridge.

1. An artificial tooth dental prosthesis comprising an enamel coating and a body, at least one of said enamel and said body comprising a matrix polymer, said enamel being laminated over said body, said enamel being prepared by molding a composition comprising from about 0.5 percent to about 20 percent by weight of one or more polymerizable silicon containing compounds within the scope of the general formula [EQU9]wherein R1 and R2 each independently is hydrogen or a lower alkenyl having from 1 to 6 carbon atoms, R3 and R4 each independently is hydrogen or a lower alkyl having from 1 to 6 carbons atoms, and j is an integer from 1 to 6 , each of said silicon containing compounds being without either a hydroxy group or an alkoxy group, said enamel being an interpenetrating polymer network.
