Described is a customized removable cosmetic or aesthetic dental veneer that secures onto a row of teeth of a patient. The dental veneer may include a pair of rear portions that secure it onto the row of teeth, each rear portion positioned at a distal end of the veneer and having: buccal, occlusal and lingual sides for one or more rear tooth, and a front portion between the pair of rear portions that covers the buccal and occlusal surfaces of the teeth between the pair of rear portions but is free of a side that covers a majority of the lingual surface of any tooth of the row of teeth between the pair of rear portions. A slot and apertures may also be provided for occlusal portions of the rear teeth. Also described is a veneer without such rear portions, which may be used with an adhesive.

Base material arrangements having at least two layers can accommodate the addition of antifungal material (nanofiller), such as in denture base resin without significantly compromising the mechanical properties and/or translucency of the base material arrangements. Antifungal agents such as nanosilver and nanozirconia can be used to modify a surface layer of the material arrangements, such as the denture base, to overcome certain known shortcomings of the modified materials, e.g., typical acrylic resins containing nanosilver and nanozirconia.

The present disclosure provides an orthodontic article including the reaction product of the polymerizable composition. Further, the present disclosure provides polymerizable compositions and methods of making an orthodontic article. The method includes obtaining a polymerizable composition and selectively curing the polymerizable composition to form an orthodontic article. Further, methods are provided, including receiving, by a manufacturing device having one or more processors, a digital object comprising data specifying an orthodontic article; and generating, with the manufacturing device by an additive manufacturing process, the orthodontic article based on the digital object. A system is also provided, including a display that displays a 3D model of an orthodontic article; and one or more processors that, in response to the 3D model selected by a user, cause a 3D printer to create a physical object of an orthodontic article.
