Abstract: A dental machining system for manufacturing a dental restoration/appliance, including: a dental tool machine which includes: a dental blank holder for movably holding at least one dental blank relative to one or more dental tools; one or more driving units each for movably holding one or more dental tools, a control unit for controlling the dental blank holder and the driving units based on construction data of the dental restoration/appliance and a plurality of machining processes specific for the manufacturing of the dental restoration/appliance from the dental blank. The control unite executes a trained artificial intelligence algorithm that predicts the machining time for manufacturing the dental restoration/appliance based on input data including: process parameters defining the machining processes respectively; and mappings which include information on the target geometry of the dental restoration/appliance.

Abstract: A dental machining system for manufacturing a dental restoration, including: a dental tool machine which includes: a dental blank holder for holding one or more dental blanks relatively movable with respect to one or more dental tools; one or more driving units each for movably holding at least one dental tool for machining the dental blanks; a determination unit for determining the type of each dental blank; an adjustment device for allowing the user to adjust the machining time, a level of quality of the dental restoration, and a level of security of the dental restoration and dental tool against machining damage. The system further includes a control unit which executes a trained artificial intelligence algorithm adapted to generate process parameters for the machining.

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.
