The present disclosure provides orthodontic articles containing reaction products of photopolymerizable compositions. The photopolymerizable composition comprises i) a monofunctional (meth) acrylate monomer in which the cured homopolymer has a glass transition temperature of 90 ° C. or higher, ii) a photoinitiator, and iii) a polymerization reaction product of the components. including. The components include 1) isocyanate, 2) (meth) acrylate monool, 3) polycarbonate diol and 4) catalyst. Further, the present disclosure provides a method for manufacturing an orthodontic article. The method comprises obtaining a photopolymerizable composition and selectively curing the photopolymerizable composition to form an orthodontic article. In addition, a manufacturing device with one or more processors receives a digital object containing data defining the orthodontic article, and the manufacturing device by a layered modeling process is used to generate an orthodontic article based on the digital object. That and, including methods are provided. Also provided is a system comprising a display displaying a 3D model of the orthodontic article and one or more processors that allow the 3D printer to create a physical object of the orthodontic article depending on the 3D model selected by the user. Will be done. |
