Zusammenfassung:A method for making a dental appliance configured to position at least one tooth of a patient includes printing a hardenable liquid resin composition on a major surface of a polymeric material to form a pattern of discrete unhardened liquid regions thereon; at least partially hardening the unhardened liquid regions to form a corresponding array of structures on the major surface of the polymeric material, wherein the structures have a characteristic cross-sectional dimension of about 25 microns to about 1 mm, and a feature spacing of about 100 microns to about 2000 microns; and forming a plurality of cavities in the polymeric material to form the dental appliance including an arrangement of cavities configured to receive one or more teeth.
