Organosilicon soft denture liners
First Claim
1. A permanent soft denture liner consisting essentially of an amount of one or more polysiloxanes selected from methacryloxypropyl-terminated polydimethylsiloxanes having the approximate structural formula ##STR9## where n is an integer having a value from 1 to 5,000, and wherein the polysiloxane is crosslinked by a material selected from suitable heat, light or chemically activated initiators with or without crosslinking agents.
