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.
