  • Publication number: 20150238288
    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).

  • Publication number: 20150219397
    Abstract: The invention relates to a dental furnace wherein a firing chamber is heated up in a first heating-up period at a first heating-up rate of more than 501 K/min, in particular more than 1001 K/min, which heats the furnace to at least 10001 C, in particular to 1100-12501 C. The first heating-up period is followed by an intermediate heating period, which is at least five minutes long, in particular at least ten minutes long, the gradient or heating-up rate of which is adapted to the material to be sintered in the dental furnace (10), and wherein this is followed by an end heating-up period (44) during which heating up is effected at a heating-up rate of more than 301 K/min, in particular approximately 501 K/min, and wherein during this the furnace temperature is held for at least five minutes, in particular for at least 25 minutes, above the temperature toward the end of the first heating-up period, and wherein forced cooling of the furnace (10) is performed after this.

  • Patent number: 9033703
    Abstract: The invention relates to a dental furnace wherein a firing chamber is heated up in a first heating-up period at a first heating-up rate of more than 50° K/min, in particular more than 100° K/min, which heats the furnace to at least 1000° C., in particular to 1100-1250° C. The first heating-up period is followed by an intermediate heating period, which is at least five minutes long, in particular at least ten minutes long, the gradient or heating-up rate of which is adapted to the material to be sintered in the dental furnace (10), and wherein this is followed by an end heating-up period (44) during which heating up is effected at a heating-up rate of more than 30° K/min, in particular approximately 50° K/min, and wherein during this the furnace temperature is held for at least five minutes, in particular for at least 25 minutes, above the temperature toward the end of the first heating-up period, and wherein forced cooling of the furnace (10) is performed after this.

  • Publication number: 20140336805
    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.

  • Publication number: 20140236342
    Abstract: A dental furnace having a display device and an operating device (10) for the dental furnace, is provided, the operating device being integrated in particular in the display device by forming a touch screen (12), and the operating device (10) facilitating the selection of programs for the firing of dental restoration parts in the dental furnace. The operating device (10) allows in particular the input of further parameters for a firing cycle. An operating element (30, 32, 34) facilitates the control of a final firing program of the dental furnace, namely with different values for the temperature as well as for the duration of the final firing, the operating element (30, 32, 34) making possible the simultaneous adjusting of temperature and duration parameters of the final firing.

  • Publication number: 20140120485
    Abstract: Provided are peptide analogues of PA-IL and compositions containing them. The PA-IL peptide analogues have altered carbohydrate binding specificity relative to a PA-IL of SEQ ID NO:1, and thus the analogues contain amino acid substitutions in SEQ ID NO:1. The substitutions can be at positions 50, 52 and 53 of SEQ ID NO:1 and can include combinations of amino acid substitutions at those positions. Also included are methods for detecting changes in the glycosylation of carbohydrates and for separating biomolecules which contain glycoproteins or glycoconjugates.
