R 3 may be the same or different h = 1 to n and said other compound that has three or more terminal acrylates has the formula wherein y=o and said formula is j and m = 1 to n k = O to n u = 1 to n v = O to n Siloxane radicals with u, k and v exponents can repeat, alternately forming multiple blocks, the blocks can be the same or different powers of u, k and v and said new composition of matter of comprising an initiator activated by actinic light within the visible light range of about 360 to about 600 nanometers.

Claim 14

The method of Claim 11 wherein said composition is carried on the surface of a removable denture that is to be juxtaposed against tissues of the oral cavity when said composition is forced toward said surface and said tissue is said surface.

Claim 15

The method of Claim 12 wherein said actinic light, except for ambient light, is substantially limited to the visible light spectrum of about 360 to about 600 nanometers, said composition is substantially stable against assuming a permanent remembered form when stored actinic light free, non-toxic in use in the oral cavity, is stable in storage for at least one (1) month as a one-component composition when actinic light free, and assumes a permanent elastomeric memory when exposed to light filtered to limited wave lengths within the visible light range for one (1) minute to a depth of one (1) inch.
