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.

Abstract: The invention relates to A curable composition for producing dental composite crowns, the composition comprising a resin matrix comprising polymerizable (meth)acrylate(s) not comprising a urethane moiety, polymerizable urethane(meth)acrylate(s), wherein the polymerizable (meth)acrylate(s) not comprising an urethane moiety are used in excess over the polymerizable urethane(meth)acrylate(s), a filler matrix comprising nanocluster(s), fumed silica in an amount below 8 wt. % with respect to the weight of the whole composition, an initiator system comprising photoinitiator(s), organic dye(s), the curable composition not comprising softener in an amount of more than 5 wt. % with respect to the weight of the whole composition, the curable composition having a viscosity below 150 Pa*s at 23° C. and a shear rate of 1 s−1.
The invention also relates to a cured article obtained by radiation curing this curable composition by use of an additive-manufacturing method.

Abstract: A method of building up a physical object by additive manufacturing which has the steps of building up the object and at least one support structure layer by layer along a build axis. The support structure supports the object relative to a build platform. During building up the object and the at least one support structure a connection is provided between the support structure and the object by a plurality of layers each of which being a common layer of the object and the support structure.
