Abstract
A method of cutting a dental aligner includes identifying a gingival line in a model representative of a user's dentition where the gingival line is an interface of a teeth portion and a gingival portion of the model, generating a plurality of points in the gingival portion of the model where each point of the plurality of points is generated at a threshold distance from the gingival line, generating a cut line that intersects at least some of the points of the plurality of points, and controlling a cutting system to cut the dental aligner along the cut line.
