Method for manufacturing a fitting device for an orthodontic apparatus

A method for manufacturing a fitting device for an orthodontic apparatus, comprising the following steps:

• making a first digitized image of a row of teeth of a patient in a first initial position, said row of teeth comprising a receiving surface;
• and then
• making a second digitized image of the orthodontic apparatus, from said first image;
• said orthodontic apparatus comprising at least two attachment elements and at least one bridge, the or each bridge connecting two attachment elements,
• each attachment element comprising an attachment surface and an opposite front surface, each attachment surface being capable of being joined to a receiving area included in the receiving surface, each receiving area corresponding to a separate tooth in the row;
• the method comprising:
• making a third digitized image of the orthodontic apparatus joined to the row of teeth in the first initial position from the first and second digitized images, each attachment surface of an attachment element being joined to the corresponding receiving area of the receiving surface;
• then
• making a fourth digitized image of a fitting device for the orthodontic apparatus from the third digitized image, said fitting device comprising:
• a contact surface capable of being assembled with the receiving surface of the row of teeth;
• at least two first cavities opening onto the contact surface, each first cavity being complementary to a front surface of an attachment element of the orthodontic apparatus;
• and at least one second cavity, the or each second cavity being capable of receiving a bridge of the orthodontic apparatus;
• then
• additively manufacturing the fitting device from said fourth digitized image using a solid material.
