(57) [Summary] (Modified) [Objective] To provide a method for forming an orthodontic stator (10). [Constitution] The contour parameters such as the vertices of the buccal and lingual cusps (62; 60, etc.), the depths of the grooves between the cusps (64, etc.) and the intersections between the teeth (58, etc.) and the gums are set. Determined for the patient's molars (58, etc.) and premolars (80, etc.), The buccal cusps (74, etc.) of the lower jaw teeth (70, etc.) are positioned relative to the upper jaw edge ridges (66, etc.). The data for the molars (58, etc.), cusps, lateral and median (100, etc.) showing this determination were individually processed to determine the position of the bracket (12) with respect to the tooth and the depth of the groove (24) in the bracket and A parameter, such as an angle, is determined to allow the archwire to be placed in the groove of the bracket for a variety of teeth in a plan view with a continuously curved shape in a plan view. |
