SYSTEMS AND METHODS FOR PLANNING AN ORTHODONTIC TREATMENT

A method, executable by a processor, of generating a 3D digital model associated with a given tooth is disclosed. The method includes obtaining a preliminary root 3D digital model of a root portion the given tooth, and then generating an augmented root 3D digital model therefrom by obtaining data of a longitudinal axis of the given tooth, and data indicative of a tooth gingiva segmentation contour between the crown and root portions; determining for each root vertex, a respective new position relative to the longitudinal axis in which the respective new position is defined by a shift distance value and a shift direction vector; moving each of the root vertices to their respective new position by applying their respective shift distance values along their respective shift direction vector; and storing the augmented root 3D digital model for determining an orthodontic treatment for the subject.
