    Abstract: The present invention relates to a method for the design and manufacture of a dental component with a surface, wherein a 3D model of the dental component is designed by means of a CAD unit and the dental component is manufactured by a CAM unit on the basis of the 3D model. In order to provide a method which significantly shortens the time required for the design and manufacture of a dental component, so that the length of the dental session at which the patient must be present is shortened, it is inventively proposed that the 3D model is manufactured in at least one first design step, in which a first 3D submodel is designed with at least one first surface section, and a second design step in which a second 3D submodel is designed with at least one second surface section, wherein the first design step is completed before the second design step and the CAM unit begins the manufacture of the first surface section of the dental component based on the first 3D submodel before the design of the second 3D submodel is completed.

    Abstract: A method of operating a stepper motor for use in a dental tool machine for removing material from a dental blank, the method including: a step of adapting torque reserves of the stepper motor at operating points to net load moments respectively. The method includes a first step of predicting, through simulation, the net load moments beforehand; a second step of predicting, through simulation, the supply current to be supplied to the stepper motor for setting up the torque reserves that correspond to the predicted net load moments respectively; and a step of driving the stepper motor based on the predicted supply current.

    Abstract: A device for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film that includes: a separating element for thermally separating the deep-drawn thermoform film and simultaneously refining the separated deep-drawn thermoform film; a heating means for regulating the heating of the separating element so as to increase the temperature of the thermoform film substantially to at least its glass temperature; a support for supporting the deep-drawn thermoform film relatively movable with respect to the separating element; a moving mechanism for moving the separating element along a separation contour of the deep-drawn jaw-spanning dental apparatus relative to the support; and a control unit adapted to control the heating means and the moving mechanism based on the separation contour.

    Abstract: A method of identifying dental consumables including at least one of a dental blank (2) and a dental tool (3) equipped into a dental tool machine (1). The method includes: a step of colliding the dental tool (3) with the dental blank (2) or a dental blank holder of the dental tool machine (1) and a step of detecting a signal indicative of the collision. The method also includes a step of analyzing the detected signal through trained artificial intelligence; and a step of identifying the type and/or condition of at least one of the dental consumables based on the analysis.
