摘要： It is an object of the present invention to provide a device (101, 201, 301, 401, 501) for producing a moulding (117), in particular a dental moulding (117), by means of electrophoretic deposition of particles (115) from a suspension (113, 213), wherein a predetermined spatial form can be specifically produced in order thereby to achieve production of the moulding (117) that is as close as possible to the final dimensions and contours. The production of the mouldings (117) is also intended to be inexpensive, resource-efficient and allow itself to be carried out quickly and as easily as possible, with good reproducibility of the method being desirable in order to achieve a low reject rate. Proposed for this purpose is a device (101, 201, 301, 401, 501) with a chamber (103, 503) for receiving the suspension (113, 213), a first electrode (105, 405, 905), which is assigned to the chamber (103, 503), a second electrode (107, 207, 307, 407, 807, 907), which is assigned to the chamber (103, 503), a support structure (107, 219, 907), which is assigned to the chamber (103, 503) and on which the particles (115) can be deposited, wherein the support structure (107, 219, 907) is formed by the second electrode (107, 207, 307, 407, 807, 907) and/or a depositing element (219) arranged between the first electrode (105, 405, 905) and the second electrode (107, 207, 307, 407, 807, 907), a voltage source (109, 409) for generating (52) an electric potential difference between the first electrode (105, 405, 905) and the second electrode (107, 207, 307, 407, 807, 907) and a positioning element (111, 111a) for carrying out a relative movement between the first electrode (105, 405, 905) and the support structure (107, 219, 907) along a first predetermined path (627) during the electrophoretic deposition. According to a further aspect, a corresponding system (with a device (101, 201, 301, 401, 501) according to the invention and a suspension (113, 213) of electrophoretically depositable particles (115)), a corresponding method, a computer program for controlling such a device (101, 201, 301, 401, 501) and also a data carrier with such a computer program are to be provided.

摘要： The invention relates to a method (100, 200, 300) for producing a dental prosthesis (17) with a framework (3) and a veneer (15), in particular for producing a crown, a bridge, an inlay or an onlay. The invention further relates to a system (40, 50) for producing a dental prosthesis (17) with a framework (3) and a veneer (15) and to a corresponding computer program. To allow the dental prosthesis (17) to be produced in a short time and in uniform quality, irrespective of the skill of the operator, the following steps are provided: definition (110, 210, 310) of three-dimensional geometrical data of the veneer (15), provision (101) or preparation (218, 318) of the framework (3), production (120, 220, 320) of a model (5, 5a, 5b, 5c, 5d) of the veneer (15) on the basis of the three-dimensional geometrical data of the veneer (15), on the framework (3) or separately, formation (124, 224, 324) of a female impression (11) of the veneer (15) by inclusion (126, 226, 326) of the model (5, 5a, 5b, 5c, 5d) between the framework (3) and a shaping material (9), and then removal (128, 228, 328) of the model (5, 5a, 5b, 5c, 5d), and filling (130, 230, 330) of the female impression (11) with veneer material for producing the veneered dental prosthesis (17).
