Abstract: Disclosed herein a dental mill blank and a method of forming the dental mill blank. The dental mill blank includes a first layer of a first hard restorative material having a first translucency and a first shade, a second layer of a second hard restorative material having a second translucency and a second shade, where at least one of the following is true (1) the first translucency is different from the second translucency, (2) the first shade is different from the second shade. The first layer and the second layer form a first interface having a first curve across a first plane of symmetry of the dental mill blank, where the first curve has a different from zero curvature; and a first straight line along the entire length of a second plane of the dental mill blank, the second plane being orthogonal to the first plane of symmetry.

Abstract: A method of coating with an aqueous coating composition having a pH <5 of silica nanoparticles having a, average particle diameter of ?40 nm, silica nanoparticles having an average particle diameter of ?50 nm, and a tetraalkoxysilane. The resulting coatings are substantially uniform in thickness, durably adheres to the substrate, and provides antireflection and or hydrophilic surface properties to the substrate.
