Abstract:
1. A computer-implemented method for dynamic adjustment of the position of a cutting tool when cutting dental aligner material, said computer-implemented method comprising: using a computer for generating digital data that define (a) a first cutting angle in a labial cutting area along a dynamic cutting curve, (b) a second cutting angle in a lingual cutting area along the dynamic cutting curve, and (c) a third cutting angle in a back molar cutting area along the dynamic cutting curve; automatically moving a cutting tool from the labial cutting area to the back molar cutting area while gradually increasing a cutting tool angle from the first cutting angle to the third cutting angle; and automatically moving the cutting tool from the lingual cutting area to the back molar cutting area while gradually increasing the cutting tool angle from the second cutting angle to the third cutting angle.
