Abstract: The present disclosure provides methods of making a hydrated orthodontic article is provided. One method includes a) providing a photopolymerizable composition; b) selectively curing the photopolymerizable composition using actinic radiation to form an article in the shape of an orthodontic article having a plurality of layers of at least one photopolymerized polymer; and c) exposing the article to water by submersion in water, thereby hydrating the article. A sheet of the at least one photopolymerized polymer has a bending modulus when hydrated of 100 MPa or greater and 2200 MPa or less. Another method includes exposing the orthodontic article to water vapor and hermetically sealing the hydrated orthodontic article in a container. Hydrated orthodontic articles are also provided, including an orthodontic article that is prepared according to one of the methods. The present disclosure further provides kits, including an orthodontic article and instructions for exposing the orthodontic article to water to hydrate the orthodontic article, as well as including a hydrated orthodontic article hermetically sealed in a container.

The polyorganosiloxane has divalent units represented by Formula (I) and greater than two -Si(Y) p (R) 3-P groups, in which each R is a non-hydrolyzable group; each Y is a hydrolysable group; and p is 1, 2, or 3. The composition further includes an amino-functional silane represented by (R 6 ) 2 N-[R 4 -Z] r -R 4 -[Si(Y) p (R 5 ) 3-P ] or a cyclic azasilane of Formula (II). Each R 4 is a linking group; each R 5 is a non-hydrolyzable group; each Z is -0- or -N(R 6 )-; each R 6 is hydrogen, alkyl, aryl, arylalkylenyl, or -R 4 -[Si(Y) p (R 5 ) 3-P ]; R 7 is a linking group that can have at least one catenated -N(R 8 )-; each R 8 is hydrogen, alkyl, or alkenyl, which may be substituted by an amino group; each Y is a hydrolyzable group; r is 0, 1, 2, or 3; and p is 1, 2, or 3.
