    Abstract: A curable dental composition includes a compound having structural formula (A) where X is an amine-, oxygen-, or sulfur-containing linkage; Y is an amine-, oxygen-, or sulfur-containing linkage; n is 1-15; m is 1-5; p is 1-5, with the proviso that when p is greater than 1, m is 1; each R1 is, independently, an alkyl or aryl group having 2 to 20 carbon atoms that is linear, branched, cyclic, or some combination thereof, and optionally includes one or more heteroatoms or unsaturated bonds; and each R2 is, independently, a hydrogen atom or CH3 The composition also includes filler. The filler is present in an amount of at least 25 wt.-%, based on the total weight of the curable dental composition.

    Abstract: The present disclosure provides a photopolymerizable composition. The photopolymerizable composition includes at least one polypropylene oxide component and an initiator, plus optionally a urethane component, a multifunctional reactive diluent, and/or an inhibitor. The present disclosure also provides an article including the reaction product of the photopolymerizable composition. Typically, the article exhibits an elongation at break of 30% or greater. Further, the present disclosure provides a method of making an article. The method includes (i) providing a photopolymerizable composition and (ii) selectively curing the photopolymerizable composition to form an article. The method optionally also includes (iii) curing unpolymerized polypropylene oxide component, urethane component and/or multifunctional reactive diluent remaining after step (ii). Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an article; and generating, with the manufacturing device by an additive manufacturing process, the article based on the digital object. A system is also provided, including a display that displays a 3D model of an 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 article.
