摘要： A system for a chemically bonded ceramic material, comprising an aqueous hydration liquid and a powdered material, the binder phase of which essentially consisting of a cement system, which powdered material has the capacity following saturation with the hydration liquid reacting with the binder phase to hydrate to a chemically bonded ceramic material. According to the invention, the powdered material comprises a first part component for the formation of an organic phase in the ceramic material and the hydration liquid comprises a second part component for the formation of said organic phase. The invention also relates to the powdered material and the hydration liquid, respectively, the formed ceramic material, a method for the production of the material and a device for storing the powdered material and mixing it with the hydration liquid.

摘要： Polymeric shells which fit over one or more natural teeth to change the perceived color of the teeth, and optionally to provide orthodontic support. The shells can be prepared by thermoforming selected polymeric sheets which contain optical additives over a physical image of the teeth, or by depositing polymeric compositions containing optical additives over a physical image of the teeth, or by additive manufacturing based upon a digital image of the teeth. The optical additives cause the combination of the shell and the teeth to have a desired appearance. At least part of the shell preferably has transparency greater than 75%, particularly greater than 85%.
