Abstract: The invention relates to a process of producing a surface-modified non-metallic dental article, the process comprising the steps of providing a non-metallic dental article having an outer and an inner surface, applying a curable composition on the inner surface of the dental article (to form a layer of the curable composition on the inner surface), applying particles on the curable composition located on the inner surface of the dental article to achieve a surface roughness Ra of 1 to 30 μm, curing the applied curable composition, the chemical composition of the curable composition being different from the chemical composition of the dental article. The invention also relates to a surface-modified non-metallic dental article obtained or obtainable by such a process and a kit of parts comprising such a surface-modified non-metallic dental article and a dental cement.

Abstract: A process of producing a surface-modified 3-dimensional article, the process comprising the steps of providing a radiation-curable composition, building-up a 3-dimensional article by radiation-curing the radiation-curable composition layer by layer, preferably by using a stereolithography or digital light processing unit, partially removing radiation-curable composition which sticks to the surface of the 3-dimensional article, treating only a portion of the surface of the 3-dimensional article to which the radiation-curable composition is stuck with particles, applying an additional curing step to the 3-dimensional article, preferably by applying heat and/or radiation. A 3-dimensional article which can be obtained by such a process and a kit of parts comprising such a 3-dimensional article.
