Abstract

A system and method for automated generating of a cutting curve on a surface is provided. A computer-implemented method for automated generating of a cutting curve on a gingival surface to facilitate cutting of an aligner material comprises the defining of initial gingival curves along the line around a tooth (LAT) on a patient's jaw, including within an interproximal area between teeth. The initial gingival curves are replaced with a modified, dynamic cutting curve comprising an offset adjustment configured to minimize weakening of a region of the aligner material within the interproximal area. This process may be suitably applied or continued for each of other the teeth and interproximal areas between those teeth. The resulting complete dynamic cutting curve may then be output for conversion into machine executable code to facilitate cutting of the aligner material.
