A dental prosthesis to be integrated into a jaw bone cavity of a pre-identified patient. An example of a dental prosthesis includes a first manufactured portion having a surface shaped to substantially dimensionally conform three dimensionally to an undersized shape of the outer three-dimensional surface shape of a root of a tooth to be replaced, and a second manufactured portion shaped to substantially conform to the three-dimensional surface of a crown of the tooth. The outer surface of the root portion can include or be coated with a biocompatible material that is suitable to be integrated into the extraction socket and adopted by existing tissue forming the socket.

A dental restoration device includes a sleeve having an exterior surface and an interior pocket that is at least partially filled with a dental cement, and a crown having an exterior surface and an interior surface that is mated to the exterior surface of the crown and bonded thereto by an adhesive disposed between the exterior surface of the sleeve and the interior surface of the crown.

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.
