Abstract: The invention relates to a method for producing a shaped body by means of a radiation-induced printing process according to the technique of the one-photon polymerization process, characterized in that the shaped body is produced by solidifying a liquid or viscous material which contains a polysiloxane component produced by hydrolytic condensation of one or more monomeric silanes having exclusively two or three hydrolyzable groups and at least one organically polymerizable radical being bonded to the silicon atom via carbon, and contains an initiator and/or catalyst for the radiation-induced polymerization of the organically polymerizable residue, and the solidification is effected by directing light onto a region of a surface of a substrate, whereby a layer of the material located there is polymerized and thereby solidified, whereupon further layers are successively solidified.

Abstract: The invention relates to a dental prosthesis comprising a first inner sub-region which has a first organically polymerized material and a second outer sub-region, which has a second organically polymerized material that is an organically modified and organically polymerized silicic acid (hetero)polycondensate. The first inner sub-region has a flexural strength of over 80 MPa according to DIN EN ISO 4049: 2009 and a lower elastic modulus than the second outer sub-region, while the second, outer sub-region has a flexural strength of at least 100 MPa according to DIN EN ISO 4049: 2009. The first organically polymerized material is preferably also an organically modified and organically polymerized material.

Abstract: A biocompatible material, wherein at least a part of a surface of the biocompatible material is characterized by a micro or nano-meter scale topographical structure comprising a plurality of features where the structure is selected to promote a predetermined cell function in vivo or ex vivo in cell or tissue culture.
