  • Patent number: 11717386
    Abstract: The invention relates to a computer program for specifying a material color of a dental restoration for which the desired tooth color is entered as a target tooth color (56) by the user, said target tooth color being the tooth color of a neighboring tooth, wherein upon specification of the material color of the dental restoration starting from the target tooth color (56) the material color of the dental restoration material is changed based on parameters such as the color of a stump and/or an abutment, the layer thickness of the dental restoration, the type of the dental restoration as well as the processing technique, wherein the specification of the material color of the dental restoration is controlled by the computer program, and wherein, once a parameter is selected, the next parameter is offered automatically, wherein the selection is limited based on parameters which are dependent on one another, such as the layer thickness, the restoration type, that is to say the indication, and the material.

  • Publication number: 20210041852
    Abstract: Methods for manufacturing a dental restoration for a patient and dental ceramics production devices are disclosed. A dental restoration may be designed based on a scan of the patient's mouth, using a CAD software module. The software module may produce conveyor channels for a positive model based on the dimensions of a muffle in relation to the size and shape of the positive model. The conveyor channels may extend at an angle of between 0° and 130° away from an axis of the pressing channel, the axis being located essentially along an isotherm inside the muffle. A docking site may be selected based on a position with the greatest wall thickness of the positive model. The present disclosure allows the creation of a high-quality dental restoration in a very efficient fashion, in particular when lithium disilicate is used as the dental ceramics material.

  • Publication number: 20190234030
    Abstract: Method for operating a ground milling machine, in particular a ground stabilizer and/or a recycler; to a ground milling machine, in particular a ground stabilizer and/or recycler, with a mobile unit, in particular for carrying out the method; and to a mobile unit for a ground milling machine. The basic idea of the invention is to transmit suggested values for dosing and/or process parameters via the mobile unit to the ground milling machine during the working operation in progress.
