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: The present invention relates to an organically-modified, organically cross-linked silicic acid (hetero) polycondensate or composite, comprising an organically-modified, organically cross-linked silicic acid (hetero) polycondensate and a filler, for intraoral application, particularly for application when repairing an existing dental replacement in the mouth of a patient or for applying an enamel layer to an anatomically-reduced, milled crown base body already located in the mouth of a patient, wherein said existing dental replacement or said crown base body is comprised of a material having free hydroxy, carboxyl, thio or amino groups, or forming these on its surface following a physical-chemical treatment and/or potentially having active C?C double bonds, comprising the following steps in the mouth of the patient: (a) If necessary, processing of the previously existing dental replacement to remove damaged or no longer necessary elements, (b) Applying a bonding agent to the surface of said potentially proce

Abstract: The present invention relates to an organically modified silicic acid (hetero) polycondensate or a composite comprising an organically modified silicic acid (hetero) polycondensate and a filler material for use in a dental procedure, particularly in a dental medicine procedure comprising at least a part or all of the following steps: (a) Transfer of said organically modified silicic acid (hetero) polycondensate or said composite in the form of a block and hardening of said block through organic cross-linking, preferably in a thermal and/or redox-induced manner, (b) Intra-oral measuring of the area requiring treatment in the mouth of the patient or a model or impression of this area outside the patient's mouth with the aid of a 3D imaging device, (c) Transfer of the produced imaging data to a computer unit, (d) Production of a virtual design to be inserted in the mouth of the patient with the aid of said computer unit, then either (e1) Grinding out a fully anatomical form of this design from a block made of
