Abstract:
1. A computer-implemented method for automated generating of a cutting curve on a gingival surface to facilitate cutting of an aligner material, said computer-implemented method comprising: generating a digital data format that defines initial gingival curves along teeth on a jaw structure of a patient within an interproximal area between two teeth; converting the digital data format that defines the initial gingival curves into a plurality of points with geometric information associated with a first pair of gingival curve portions of the initial gingival curves residing on each side of the interproximal area; generating a digital data format that defines a dynamic cutting curve within the interproximal area that is made to fit through at least a portion of the plurality of points with geometric information; and converting in a microprocessor the digital data format that defines the dynamic cutting curve into machine executable code for cutting of the aligner material.
