Abstract

In one embodiment, an orthodontic article is described comprising the reaction product of a polymerizable composition comprising: a) 30-70 parts by weight of monofunctional (meth)acrylate monomer, wherein a cured homopolymer of at least one monofunctional (meth)acrylate monomer has a Tg of at least 30, 35, 40, 45, 50, 55, or 60° C.; and b) urethane (meth)acrylate polymer comprising polymerized units of an aliphatic polyester diol. Also described are polymerizable compositions, as well as methods and systems for making an article utilizing 3D printing.
