摘要： The invention relates to a sintering furnace for components consisting of sintering material, especially dental components and in particular components consisting of ceramic, and a method for sintering such components. The sintering furnace 1 comprises a heatable furnace chamber 2 for the component 9 to be sintered, the furnace chamber 2 having a wall section 6 to be opened for inserting the component 9 to be sintered into the furnace chamber 2. Drive means 10 are provided for mechanized opening and closing of the wall section 6, and a control 11 is provided for the drive means 10 that has an actuation element 12 for the drive means 10. Furthermore, a heating device 5 for the furnace chamber 2 is provided, and the control 11 causes the furnace chamber 2 to be heated. Actuating the control element 12 triggers the loading sequence of the control 11, and the drive means 10 are automatically actuated by the control 11 corresponding to the loading sequence. An additional subject is a method for operating the sintering furnace, as well as a computer program therefor.

摘要： The invention relates to a method for designing a plurality of adjacent tooth restorations using CAD/CAM technology. In a first step, the virtual model of a first tooth restoration at the first border of the restoration site is designed. In a second step, the virtual model of the second tooth restoration adjacent to the first tooth restoration is designed, the second tooth restoration being adjusted to match the first tooth restoration. The virtual model of the first tooth restoration is adjusted in relation to the second tooth restoration in a third step, if required. This procedure is then repeated for all of the other tooth restorations in the restoration site.

摘要： The invention concerns a device (1) for editing a virtual 3-D model (2) of teeth (2.1, 2.2, 2.3, 2.4) positioned in a dental arch (9, 11) by means of a virtual tool (21, 22, 23, 24, 25, 26, 27, 28, 50). The tool (21, 22, 23, 24, 25, 26, 27, 28, 50) can be used on a first tooth (2.1, 2.3) of the 3-D model (2), whereby the corresponding application is carried out on a second mirrored tooth (2.2, 2.4), contralateral to the first tooth with respect to a plane of symmetry (12), that is, on the tooth on the other side of the plane of symmetry (12), which is positioned as a mirror image of the first tooth (2.1, 2.3) with respect to the plane of symmetry (12).

摘要： The invention relates to a method for validating a drilling template for producing an implant-borne tooth replacement before performing an implant drilling. The drilling template produced is placed on dental structures of a jaw area that is to be provided with the tooth replacement. A measuring element is inserted into the drill guide of the drilling template, wherein the measuring element and at least one partial region of the dental structures not covered by the drilling template is measured using an optical three-dimensional measuring method. Then the position and orientation of the measuring element in relation to the partial region of the dental structures are determined from the generated measured data of the optical measurement, wherein a virtual actual implant drilling model is created on the basis of the optical measured data using the position and orientation determined for the measuring element, and/or using the known dimensions of a drill to be used, and/or the position of a stop surface on the drilling template for the drill to be used, wherein the actual implant drilling model is compared with a planned virtual target implant drilling model from a previous implant planning with respect to its position and its orientation.

摘要： A method for recording an image of an object includes projecting a strip pattern onto the object, recording the projected strip pattern as raw image data using a camera, and calculating an image of the object from the raw image data. A strip pattern having a duty cycle of less than 1 can be used to increase measuring precision during measurement of a translucent object, and can eliminate a need for additional contrast agents for a recording of the object.
