Abstract
Provided herein are crosslinked polymers useful in orthodontic appliances and light polymerizable liquid compositions and formulations useful for making crosslinked polymers. Also provided are methods of making an orthodontic appliance comprising a cross-linked polymer formed by a direct fabrication technique.
Claims20
A light polymerizable composition comprising:
- a first polymerizable component, wherein the first polymerizable component is a urethane (meth)acrylate prepolymer comprising repeating units comprising, in a polymerized form, an aliphatic polyester diol monomer;
- a second polymerizable component, wherein the second polymerizable component is a monofunctional (meth)acrylate monomer not including a urethane linkage;
- and
- a photoinitiator,
- wherein the light polymerizable composition is incorporated into a cross-linked polymer by 3D printing, wherein the cross-linked polymer forms a 3D printed object.
