Abstract
Systems and methods of defining a trimline in relation to modeled teeth including a three-dimensional model of one or more intraoral surfaces of the patient. The trimline is for use to manufacture an aligner. For one or more pairs of adjacent teeth, a scallop plane is defined based on a scallop factor. The scallop plane is used to determine the position of scallop points on a line around each tooth adjacent to an interproximal region of the pair of teeth. Transition points are then defined on the line around each tooth apically of the scallop points, and the points connected to form an initial connector curve. The initial connector curve is projected on to a mesh of the three-dimensional model, and smoothing applied to the resulting segmented connector curve. The smoothed connector curves are then joined by teeth curves to form the trimline.
