Method and apparatus for recommending orthodontic treatment plan by separating tooth object from three-dimensional oral scan data and automatically determining positional abnormality of tooth, and computer-readable recording medium

Abstract

The method for recommending an orthodontic treatment plan by analyzing three-dimensional oral scan data comprises: increasing a size of a circle from the center of coordinates of the three-dimensional oral scan data; reversing a vector direction of a mesh, duplicating spheres while moving the spheres at a random speed in a peripheral direction from reference coordinates, and arranging the spheres inside the teeth; determining a representative sphere corresponding to each tooth, and extracting feature data of the teeth on the basis of a contact point and coordinates of the representative sphere; implementing the examinee's tooth arrangement using feature data extracted for each tooth and axis data for each tooth; applying a relative arrangement state of tooth objects included in tooth arrangement data to an automatic diagnosis algorithm; and combining classification results for the positional abnormality of the teeth to generate oral state information about the examinee before the treatment.
