The invention relates to a method for producing a dental model for removable insertion in a recess of a holder, which dental model has a referencing, comprising at least one tooth part having a base to be inserted into the recess, wherein the at least one tooth part is produced using digitized data of a jaw in that the digitized data are saved in a computer beforehand and supplied to a processing machine to produce the at least one tooth part. In order to ensure simple handling of the dental model and in particular to prevent faulty insertion of the dental model or segment, according to the invention the referencing is saved in the computer and, in consideration of the referencing, the at least one tooth part is produced as having the base as a unit.

Method for producing a dental model and carrying plate for receiving same

A method for manufacturing a shaped body, comprising creating a mixture of a metal powder and binding agent, compacting the mixture to form a green compact, heating the green compact to a debinding start temperature T, debinding the green compact by controlled heating of the green compact from start temperature Tto end temperature Tat a heat-up rate R, presintering the debindered green compact to the presinter end temperature Tat a heat-up rate R, cooling the green compact from the presinter end temperature Tat a cool-down rate R, whereby at least the heat-up rate R, the presinter end temperature T, and the cool-down rate Rare tuned relative to each other in such a way that the presintered green compact forming a blank has a surface porosity of 16% to 22% after presintering, and machining and sintering of the blank to form the shaped body.

Method for the manufacture of a shaped body as well as a green compact

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.
