  • Publication number: 20230150185
    Abstract: A hand tool (1) for separating a deep-drawn jaw-spanning dental apparatus such as an aligner or a bite splint of thermoform film. The hand tool includes a grip (2) for holding; a separating element (3) for thermally separating the deep-drawn thermoform film and refining the separated deep-drawn thermoform; a heating device adapted to regulate heating of the separating element (3) so as to increase the temperature of the thermoform film substantially to at least its glass temperature; and a power supply device for supplying electric power to the heating device.

  • Publication number: 20230144773
    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.

  • Publication number: 20220378560
    Abstract: A dental machining system for manufacturing a dental restoration including: a dental tool machine (1) which has: a dental blank holder for holding at least one dental blank (2) relatively movably with respect to one or more dental tools (3); one or more driving units (4) each for movably holding at least one dental tool (3) for machining the dental blank (2), a control unit for controlling the dental blank holder and the driving units (4) based at least on a temporal trajectory of the dental tool (3) relative to the dental blank (2) and a spatial amount of material removal from the dental blank (2) along the temporal trajectory. The control unit executes a trained artificial intelligence algorithm.

  • Publication number: 20220359065
    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.

  • Publication number: 20220331074
    Abstract: A method of machining at least one dental restoration (1) from a workpiece (2) using one or more dental took (3), including a step of defining, a target contour (4) of the dental restoration (1); also including a step of predicting the deflection of the dental tool (3) during pre-machining through a model based on one or more machining parameters; a step of determining based on the prediction step one or more primary locations (5) at which the target contour (4) would have been damaged during pre-machining; a step of modifying the target contour (4) or the corresponding machining path by adding an oversize of material (6) substantially only at the primary locations (5) for preventing damage; and a step of pre-machining the workpiece (2) based on the modified target contour (17) or the corresponding modified machining path.

  • Publication number: 20220304782
    Abstract: Using a configuration recommendation module, a recommendation for configuring a dental manufacturing system is proposed. The recommendation takes into consideration user-specific information such as preferred dental practitioner tools, preferred restoration esthetics and dynamic and static inputs automatically retrieved by a CAD/CAM (computer-aided design/computer-aided manufacturing) resource.

  • Publication number: 20220278635
    Abstract: The present invention relates to a method of operating a stepper motor for use in a dental tool machine (1) for removing material from a dental blank (2), the method comprising: a step of adapting torque reserves of the stepper motor at operating points to net load moments (M_net) respectively, characterized by further comprising: a first step (S1) of predicting, through simulation, the net load moments (M_net) beforehand; a second step (S2) of predicting, through simulation, the supply current (I_tr) to be supplied to the stepper motor for setting up the torque reserves that correspond to the predicted net load moments (M_net) respectively; and a step (S3) of driving the stepper motor based on the predicted supply current (I_tr).

  • Publication number: 20210393381
    Abstract: The invention relates to a method for producing ceramic dental prosthesis parts by way of a CAD/CAM machining station, comprising the following steps:—providing a disk-shaped ceramic blank, wherein the blank has the final strength;—attaching the blank in a mounting device of the CAD/CAM machining station;—controlling the CAD/CAM machining station for establishing an initial contact between the blank and the grinding tool in such a way that, due to the rotation of the grinding tool about the longitudinal axis (13) thereof, the entire contact surface (21) between the grinding tool and the blank has relative movement; and—machining the blank by way of the rotating grinding tool, proceeding from the initial contact, to produce the ceramic dental prosthesis parts.
