Abstract: A method of thermoforming is described. The method comprises providing a multilayer polymer film comprising at least one first thermoplastic polymer layer having a glass transition temperature (Tg) greater than 60°C and at least one second polymer layer; and thermoforming the multilayer polymer film into a three-dimensional shape. The second polymer layer can be characterized by one or more properties selected from i) a Tg ranging from 20 to 70°C; ii) a molecular weight between crosslinks of no greater than 20,000 g/mole; and iii) sufficient crosslinking such that the second polymer layer lacks a thermal melt or softening transition at a temperature up to the decomposition temperature of the second polymer layer. Also described are multilayer films and articles, such as orthodontic aligner and retainer trays.

Abstract: The present disclosure provides a metal based dental article and a method of forming the metal based dental article. The metal based dental article includes a base layer, a first coating on the base layer and a second coating on the first coating. The base layer is formed from a metal substrate selected from the group consisting of a stainless steel, a titanium alloy or a nickel titanium alloy. The first coating is formed from a metal selected from the group consisting of nickel, a nickel alloy, copper, a copper alloy, zinc, a zinc alloy, tin, a tin alloy, gold or a gold alloy, where one of the first coating or the surface of the base layer has a surface roughness (R a ) from 0.1 to 1.0 microns as measured according to ASTM B46.1-2009. The second coating is formed from a metal selected from the group consisting of rhodium, a rhodium alloy, ruthenium, a ruthenium alloy, cobalt, a cobalt alloy, palladium, or a palladium alloy. The second coating has a predetermined thickness that provides the metal based dental article with a matte finish and a whiteness, L*, of at least 80 of the CIELAB color system (L*, a*, B*).

Abstract: A method for making a dental appliance includes depositing an image layer on a major surface of a water-soluble polymeric image carrier substrate; placing the water-soluble image carrier substrate in an aqueous liquid to at least partially dissolve the image carrier substrate; immersing into the aqueous liquid a substantially flat polymeric transfer substrate through the image layer such that the image layer transfers to a surface of the transfer substrate; and removing the transfer substrate from the aqueous liquid with the image layer bonded to the surface thereof. The transfer substrate may be formed into a dental appliance with a graphic image thereon.
