DENTAL PROSTHESIS WITH A MULTIPART DESIGN, AND METHOD AND DEVICE FOR PRODUCING SAME

摘要

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. The dental prosthesis can be generated preferably using a mold system consisting of at least one first and a second negative mold, and the second negative mold is shaped so as to form a second cavity. Either both negative molds consist of at least two parts or the first negative mold is a single part and has an opening for the admission of light or IR radiation.
