摘要： A device for producing dental ceramic, with a CAD/CAM device for preparing a compression molding cavity for producing the dental ceramic, wherein a CAD device thereof, on the basis of scan data, determines the shape of the dental ceramic to be produced, and wherein a CAM device thereof produces a positive model, on the basis of which the mold cavity is produced via a sacrificial mold (muffle). The CAM device also determines the distribution and the transfer between different ceramic types, i.e. types of ceramics that differ at least in respect of one parameter in terms of material, appearance, strength or the like, wherein the CAM device for adjusting the distribution and the transfer determines the position and the dimensions of a feed channel between a muffle rod and the compression molding cavity for producing the dental ceramic according to at least one of these parameters.

摘要： 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.

摘要： 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.

摘要： A dental restoration model including a positive model (15) of a dental restoration piece. The positive model (15) defines at least the outer contour (36) of a dental restoration piece to be made using lost wax technology and is provided with a locating pin region which is defined especially according to a given optimization process. The locating pin region is provided with a guiding element (30) which accommodates and/or guides a material feeder (22, 24, 26 and 28).
