The present disclosure provides an orthodontic article including the reaction product of the polymerizable composition. Further, the present disclosure provides polymerizable compositions and methods of making an orthodontic article. The method includes obtaining a polymerizable composition and selectively curing the polymerizable composition to form an orthodontic article. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an orthodontic article; and generating, with the manufacturing device by an additive manufacturing process, the orthodontic article based on the digital object. A system is also provided, including a display that displays a 3D model of an orthodontic article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an orthodontic article.

Provided are a photocurable fluoropolyether-based elastomer composition having both a favorable preservation stability and fast curability, being bondable at a low temperature in a short period of time, and generating no air bubbles in the resin at the time of curing; and a bonding method thereof. The photocurable fluoropolyether-based elastomer composition contains: (A) a linear polyfluoro compound; (B) a fluorine-containing organohydrogenpolysiloxane; (C) a photoactive hydrosilylation reaction catalyst; and (D) a zeolite having an average primary particle size of not larger than 30 m.
