    Abstract: The present disclosure provides for a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer (102) of a first hard restorative material having a first translucency and a first shade, a second layer (104) of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true: the first translucency is different from the second translucency, the first shade is different from the second shade. The first layer (102) and the second layer (104) form a first interface having a first curve (112) across a first plane of symmetry (114) of the dental mill blank, where the first curve (112) has a different from zero curvature; and a first straight line (122) along the entire length of a second plane (118) of the dental mill blank, the second plane (118) being orthogonal to the first plane of symmetry (114).

    Abstract: A dental appliance is described, the dental appliance including a polymeric substrate with a plurality of cavities for receiving one or more teeth, an arrangement of engineered microstructures on the substrate wherein the engineered microstructures include a therapeutic agent. The microstructures may be three-dimensionally engineered on a polymeric film disposed on a major surface of the polymeric substrate, wherein the microstructures extend outwards from the surface. The microstructures also comprise a compound releasable from the three-dimensionally engineered microstructures over a predetermined patient wear time.
