Patent number: 9764513Abstract: The invention relates to a method for the construction of a shaped body from photopolymerizable material by using lithography-based generative production, in which a layer of liquid photopolymerizable material is defined on a production platform, and is polymerized in an exposure region having a predetermined contour, a further layer of photopolymerizable material is defined, the layer defined last is polymerized in an exposure region having a predetermined contour for the layer defined last, and the latter two steps are repeated until a shaped body having a predetermined shape has been formed by the sequence of cured layers with contours predetermined layer by layer, each exposure in an exposure region having a predetermined contour being carried out by controlled activation of individual exposure elements in a two-dimensional array of exposure elements, each exposure element being assigned an image element, wherein the exposure of the exposure region is carried out by a common light source and by a two-dimeType: GrantFiled: August 21, 2013Date of Patent: September 19, 2017Assignees: Ivoclar Vivadent AG, Technische Universität WienInventors: Jürgen Stampfl, Johannes Homa, Johannes Patzer, Gerald Mitteramskogler, Jörg Ebert, Jürgen Laubersheimer, Wolfgang Wachter

Patent number: 9662188Abstract: The invention relates to a method for producing a dental restoration part, in which method, geometrical data, in particular data with respect to spatial dimensions, position and/or volume of the restoration part, are determined and stored in order to form a virtual restoration part. In a further process step, the virtual restoration part is provided for the tooth (10) to be replaced by using data of the tooth (10) to be replaced, a neighboring tooth (60) and/or a tooth stump, and said data is stored as color data and is used for the computer-assisted production of the virtual restoration part.Type: GrantFiled: February 13, 2012Date of Patent: May 30, 2017Assignee: Ivoclar Vivadent AGInventors: Jürgen Laubersheimer, Wolfram Murr, Gottfried Rohner, Nadja Schlechtriemen

Publication number: 20160059495Abstract: The invention relates to a process for the layered construction of a shaped body by means of a 3D inkjet printing process with a piezo printhead (2) with several nozzles (6), to each of which a piezo element (8) is allocated which can act on the associated nozzle, in order to discharge ink from it. The piezo printhead (2) is moved, controlled by a control unit, over a construction area, the piezo elements are actuated individually for the locally selective application of filled ink, in order to apply a layer with a contour predetermined by the control unit. The applied layer is allowed to cure and the desired shaped body is constructed by successive application of layers, each with a predetermined contour.Type: ApplicationFiled: March 24, 2014Publication date: March 3, 2016Inventors: Jürgen Laubersheimer, David Schmid

Patent number: 9228782Abstract: The invention concerns a microwave oven (10) for the heat treatment of ceramic components, in particular of dental ceramic components (12). It is equipped with a susceptor (14) which is positioned in the swell or in the area between a source of microwaves and the component. The susceptor (14) is made of highly pure silicon carbide of hexagonal, rhombohedral or cubic crystal structure, which has in particular a 2H, 4H, 6H or 3C crystal structure.Type: GrantFiled: September 26, 2011Date of Patent: January 5, 2016Assignee: Ivoclar Vivadent AGInventors: Rudolf Jussel, Jürgen Laubersheimer, Christian Werling
