Method for manufacturing orthodontic device by using insertion path

A method for manufacturing an orthodontic appliance using an insertion path, comprising:

• displaying, on a screen, the insertion path for determining the insertion direction of the appliance (S01);
• designating a tooth targeted for the insertion path setting (S02);
• setting the insertion path for the designated tooth in an arbitrary direction (S03);
• displaying, on the screen, undercuts of each tooth caused by the set insertion path (S04);
• calculating and storing depth values of the undercuts for each tooth (S05);
• calculating and storing the total sum of undercut volumes for each tooth (S06);
• setting the insertion path in a different direction and repeating steps S04 through S06 (S07);
• and
• selecting and storing the insertion path having the minimum total undercut volume obtained from step S07 (S08).
