| 20110236254 | DENTAL ALLOY - A palladium-dominated dental alloy, in particular a ceramic-bonding dental alloy for the manufacture of dental prostheses such as crowns, bridges, inlays, or onlays, containing at least gold, palladium, and silver, as well as a grain-growth inhibitor in the form of ruthenium. In order to achieve a fine-grained separation without the formation of agglomerates to obtain a dental alloy with high mechanical stability and excellent polishing characteristics, it is proposed that the dental alloy contain—in addition to ruthenium as grain-growth inhibitor—at least one element of the group tantalum, niobium, yttrium, zirconium, chromium, and molybdenum as grain-refinement control element. | 09-29-2011 |
| 20110194121 | METHOD AND APPARATUS FOR DETECTING CONTOUR DATA AND/OR OPTICAL CHARACTERISTICS OF A THREE-DIMENSIONAL SEMITRANSPARENT OBJECT - A method for detecting contour data of a three-dimensional object, where a grid of illumination points of a multi-point illumination is projected onto the object using an optical device and the illumination points are then projected back onto a sensor containing pixels. In order to improve signal-noise ratio and reduce background signal, it is proposed that a grid of illumination points of at least two multi-point illuminations are projected onto the object, that the beams of the illuminating points of are modulated in intensity and that a frequency-selective and/or phase-selective detection is performed of mutually associated first and second illumination points back-projected onto the sensor. The first illumination points derive from a first of the multipoint illuminations and the second illumination points derive from a second of the multipoint illuminations. Differences in intensity and/or frequency of the measurement signals of adjacent pixels of the sensor on which the mutually associated first and second image points are depicted are evaluated for the purposes of determining the contour data. | 08-11-2011 |
| 20110111360 | METHOD FOR DETERMINING 3D DATA FROM AT LEAST ONE PREPARED MAXILLARY AREA - A process for determining 3-D data of at least one prepared jaw area, such as a prepared tooth stump, by mechanically scanning the jaw area and digitizing the measured values determined during the scanning. The jaw area is prepared with a dental instrument having positions which are optically measured during the preparation, and the 3-D data is determined from the positions of the dental instrument that are associated with the prepared jaw area. | 05-12-2011 |
| 20100240012 | METHOD FOR FABRICATING AN ABUTMENT - A method for fabricating an individual abutment for a dental prosthesis for use in an implant anchored in an area of the jaw with an implant attachment running on the abutment side, using a working model molded by the jaw area equipped with the implant. For this, the sulcus area of the gum uncovered above the implant and shaped by a sulcus-former extending from the implant attachment is reproduced in the working model. The abutment to be fabricated includes a sulcus section running within the sulcus area and an adjoining head section to admit a part of a dental prosthesis. So that the area of the abutment running below the gum line is geometrically adapted to it, it is proposed that the sulcus area of the working model having an auxiliary implant attachment corresponding to the implant attachment be measured, and on the basis of the data obtained by the measurement, a sulcus section model be determined with a circumferential surface and a de-facto sulcus line limiting it on the implant side. Missing data between the determined auxiliary implant attachment and the de-facto sulcus line are supplemented by library data which are assigned to the sulcus-former. The data of the sulcus section model are used, while allowing for the de-facto sulcus line or the auxiliary sulcus line and the library data to produce the sulcus section. | 09-23-2010 |
| 20100239996 | METHOD FOR DETERMINING THE POSITION OF AN INTRAORAL MEASURING DEVICE - A method for determining the position of an intraoral measuring device which is to be moved relative to an organ of mastication of a patient and with which positions in the organ of mastication or areas of the organ of mastication are measured. To be able to carry out measurements without a fixed reference, it is proposed that, independently of a reference that is independent of the patient, the position of the measuring device is measured by means of a position-determining sensor that is in a fixed relationship to the measuring device. | 09-23-2010 |
| 20100099984 | MEASURING ARRANGEMENT AND METHOD FOR THE THREE-DIMENSIONAL MEASUREMENT OF AN OBJECT - A measuring arrangement and a method for the three-dimensional measurement of at least part of an object includes a light source with a continuous spectrum, a device for generating a multifocal lighting pattern, a lens with a large chromatic aberration for imaging foci of the lighting pattern on the object, a detection unit for generating the wavelength spectrum of the foci that are confocally imaged on the object via the lens, and a spectrum-dispersive device disposed between the confocally imaged foci and the detection device. In order to create a highly accurate surface profile in a relatively short time even in the case of moving objects, the invention proposes that a first hole pattern including first holes be disposed in the plane of the confocally imaged foci, the geometric arrangement of the first holes corresponding to the geometric arrangement of the foci of the multifocal lighting pattern. | 04-22-2010 |
| 20100062396 | METHOD FOR PRODUCING A MULTIPART CONSTRUCTION AND SUCH A CONSTRUCTION - A method for manufacturing a multipart assembly of sintered oxide ceramic material, including one first component which at least partially surrounds one second component in such a manner that detaching the first component from the second component is not possible without destroying the first and/or second component. The assembly is produced by producing a single-part first shaped part and a single-part second shaped part from an oxide ceramic blank, whereby the first shaped part and the second shaped part are enlarged to compensate for the shrinkage during sintering, and assembling the sintered shaped part as second component with the first shaped part and subsequently sintering them together. As the first shaped part is employed a shaped part with an opening whose effective cross section after sintering is either smaller than the effective cross section of the second shaped part after sintering in a region that extends within the first component, or is smaller that the effective cross section of the second component in front of and behind the opening. | 03-11-2010 |
| 20100015570 | PROCEDURE FOR DIMENSIONALLY ACCURATE SINTERING OF A SHAPED PIECE - A procedure for dimensionally accurate sintering of a shaped piece manufactured from a blank of porous ceramic material, in which during the sintering, the shaped piece remains connected via at least one first connection like a rib, with a support that is manufactured from the blank. To ensure with simple procedural steps and simple design measures that the geometry does not change during sintering, the invention provides that the support is manufactured as a section of the blank that at least in sections surrounds the shaped piece by materials removal processing from the blank, and after the manufacture, the support, for one, is connected via the at least one first connection with the shaped piece, and for another, via at least one second connection with the residual blank that in sections is separated from the support. | 01-21-2010 |
| 20090268208 | METHOD AND DEVICE FOR DETECTING THE CONTOUR DATA AND/OR OPTICAL CHARACTERISTICS OF A THREE-DIMENSIONAL SEMI-TRANSPARENT OBJECT - A method and device for detecting the contour data and/or optical characteristics of an object, such as a tooth or a tooth restoration, based on an interference and/or autocorrelation measurement using an image sensor. To permit an exact surface detection in addition to a determination of the optical characteristics of the object, individual light beams strike the object, which are located at a distance from one another in such a way that no impact of reflected individual light beams takes place on immediately adjacent pixels of the image sensor. | 10-29-2009 |
