Patent attributes
A method and a system for determining an orthodontic treatment for a plurality of teeth of a subject are provided. The method comprises: receiving a 3D representation of a first tooth and a second tooth, adjacent thereto, of the subject, of a plurality of teeth of the subject; obtaining a tooth-gingiva segmentation loop; identifying an outer set of vertices positioned outside the tooth-gingiva segmentation loop and an inner set of vertices positioned inside the tooth-gingiva segmentation loop; determining a shortest path from the outer set of vertices to the inner set of vertices; generating, based on the shortest path, a first interdental loop indicative of an interdental boundary between the first tooth and the second tooth, the first interdental loop intersecting the tooth-gingiva segmentation loop; generating a boundary between the first tooth and the second tooth, the boundary including the tooth-gingiva segmentation loop and the first interdental loop.
