The invention relates to a method and apparatus for carrier-free deflection electrophoresis, in which a separating media and a sample to be examined flow through a separating chamber between a pair of electrodes in a series of reversing bulk fluid flow along the direction of the electrodes, thereby separating the sample into zones which are to be collected into fractions for analysis or further processing. Among other things, the apparatus and method enable high-resolution separation of particles that can be performed in miniaturized chambers in electrophoresis modes including isoelectric focusing, zone electrophoresis, and isotachophoresis.

The invention relates to a blank for a tooth replacement part comprising a first section having a shape of a section of a tooth or a tooth replacement part, and a second section comprising a material stock, which can be machined to a desired shape, e.g. by milling it off. The invention further relates to a method of producing a tooth replacement part, wherein a blank is machined by a removing process such as milling or laser machining to obtain a desired shape of a tooth replacement part, wherein only portions of the blank are machined while other portions remain unmachined because they already have the desired final shape. The invention also relates to a set comprising at least one above-defined blank and at least one counterpart, which is provided with a receptacle for holding the blank adapted at least partially to the first section and/or to the second section.

摘要:
Surface mapping and/or generation device is provided, with a device for mapping 3D data of at least one denture base object such as a tooth stump or an implantation abutment, and an environment thereof, as well as with a device for the data-based generation and production of a denture part incorporating the 3D data of the denture base object. Additionally provided are a device for determining and/or defining a placement direction of the denture part that is to be slipped onto the denture base object, and a device for determining and producing a primary part that is to be slipped onto the denture base object before the denture part and that yields a desired placement direction for the denture part which is different from the placement direction that exists for slipping the primary part onto the denture base object. The device for data-based generation and production of a denture part is designed to generate and produce the latter by incorporating the 3D data of the primary part. Surface mapping and/or generation method is provided, wherein 3D data from a denture base object such as a tooth stump or an implantation abutment and an environment thereof are mapped and then, based on this 3D data of the denture base object, a denture part to be slipped thereon is produced. Before production of the denture part, a placement direction of the denture part onto the denture base object is determined or defined. On the basis of this 3D data of the denture base object, a primary part is determined and produced, with which a desired placement direction that differs from the placement direction that exists for slipping the primary part onto the denture base object is created for the denture part. On the basis of the 3D data, the denture part is generated and produced based on data so as to fit when pushed onto the primary part.
