    摘要: 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.

    摘要: The invention relates to a process for determining the form a duplicate of a residual tooth area, which is to be fitted with a dental restoration whereby the duplicate sections to be fitted with the restoration are removed from the duplicate and the form data to be allocated to their forms has to be determined and stored in a computer, by means of which the form of the restoration is calculated taking into consideration the spatial allocation of the duplicate sections. In order to be able to determine the shape of the residual tooth area to be fitted with the restoration, and thereby determine the shape of the restoration itself with high precision, it is proposed that the duplicate sections are or are being individually referenced to each other in their spatial allocation to each other according to a referencing stored in the computer.

    摘要: The invention relates to a method and an apparatus for a non-contact, three-dimensional determination of the shape of a dental technology object (10) whereby, to determine the space coordinates of the object's surface points to be measured, a thin stripe of light projected onto the object is measured by at least two matrix cameras (32, 34) to determine two space coordinates (Z- Y-coordinate) of a coordinate system, and the third space coordinate (X coordinate) is ascertained by determining the position of the object arranged on a measuring table (22) which is rotatable about an axis of rotation (20). For allowing, in an easy manner, a non-contact determination of the shape of the dental technology object, whereby the constructive effort to determine the spatial coordinates is kept low and the shape acquisition should still be performed highly precisely and at high speed, it is provided that the matrix camera is a color matrix camera with first, second and third pixels, that the matrix camera captures light in a range of wave lengths characteristic for one type of the pixels (first pixels) and the values at least of one of the other types of the pixels (second and third pixels) are analyzed to determine the two first location coordinates (Y- and Z-coordinates).
