Abstract
The present disclosure provides an orthodontic article including the reaction product of the photopolymerizable composition. The photopolymerizable composition includes i) a monofunctional (meth)acrylate monomer whose cured homopolymer has a glass transition temperature of 90 degrees Celsius or greater; ii) a photoinitiator; and iii) a polymerization reaction product of components. The components include 1) an isocyanate; 2) a (meth)acrylate mono-ol; 3) a polycarbonate diol; and 4) a catalyst. Further, the present disclosure provides a method of making an orthodontic article. The method includes obtaining a photopolymerizable composition and selectively curing the photopolymerizable 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.
