  • Patent number: 11880635
    Abstract: The invention relates to a plausibility checking method for rapid prototyping devices, in particular for stereolithography devices. In this connection, input data (14) is checked which is present particularly in the form of graphics data and of which every file renders a layer. Every layer comprises a plurality of pixels. The component to be printed in the respective layer is produced based on output data by the rapid prototyping device. The input data of two consecutive layers is checked and the sum of all pixels to be exposed is determined for every layer. A signal (22) is output in particular as a warning signal (26) when the pixel sum of a following layer is larger than in the previous layer by a predetermined factor.

  • Publication number: 20230008250
    Abstract: A dental device with a speech recognition module is provided, which is connected to a control device that controls at least part of the functions of the dental device. Based on the recognition result, the speech recognition module triggers a selected function of the dental device via the control device and has at least one microphone. An output module outputs information about the triggered function. The speech recognition module continuously listens via the microphone and has a code word module that activates or leaves active speech recognition for the temporally successive words when a code word is recognized and attempts to recognize them as predetermined control words each assigned to a function.

  • Patent number: 10219881
    Abstract: The invention relates to a dental furnace comprising a firing hood equipped with a heating device that is movably supported for the opening and closing of the dental furnace relative to a base intended for receiving a dental restoration part, and further comprising a heat detection device that is directed towards an area above the base, in particular towards one or more dental restoration parts, and further comprising a control or regulating device for the dental furnace that is coupled to the heat detection device, wherein the heat detection device is configured as a thermal imaging camera (30) which is directed towards the area above the base while the firing hood (12) is partially or completely opened, and which feeds an at least two-dimensional image in the form of a matrix of the one or more inserted dental restoration parts (60) to the control or regulating device and/or to a muffle (26) that is intended for the generation of the dental restoration parts (60).

  • Patent number: 10182891
    Abstract: The invention relates to a dentel device for the treatment of a dental restoration part, comprising at least one operating program, a storage of the dental device and at least one detection device for at least one object. The detection device can detect data of the object and this data, in particular together with an operating program associated with the object, can be stored in a storage of the dental device or can be compared to the data of objects which have been stored in advance in the storage of the dental device. The dental device, depending on the comparison result of the data of a detected object with the data of objects which have been stored in advance in the storage of the dental device, starts the associated operating program or shows it for selection.

  • Patent number: 9931188
    Abstract: A dental color key having at least two different color patterns or samples with different tooth colors. The entire surface area of the color key (10) may be smaller than the buccal and/or labial surface area, that is to say the vestibular surface area of two teeth, and the color patterns or samples (12) are attached adjacent to one another and particularly mounted to one single tooth.

  • Patent number: 9579171
    Abstract: A process for manufacturing a dental restoration part as well as a dental furnace are provided in which the dental restoration part is produced on a foundation by means of applying at least two layers, wherein initial data, in particular three-dimensional data of the foundation, are stored in a memory device, and picture data, in particular three-dimensional data concerning the outer contour of the dental restoration part to be produced and the layers of the dental restoration part to be applied, are determined and in particular stored. It is provided that the dental restoration part is positioned at least partially during its production within the picture recording area of a picture recording device (30), and that before finishing the dental restoration part (20) and upon the application of at least one layer, the latter is recorded at least with regards to the thickness of the layer and/or its color, is displayed in particular via a display device (16).
