Final answer:
Braces are used to apply forces to teeth, and the placement of the ties or braces should be based on the orthodontist's instructions.
Step-by-step explanation:
The question seems to be asking about how to position braces or ties when they are being used in orthodontic treatment. Braces are used to apply forces to teeth to realign them. In orthodontics, the braces are attached to the teeth using bands, brackets, and archwires. The wire applies tension on the teeth to move them into the desired position. The ties or rubber bands are used to hold the wire in place and exert additional forces when needed. When it comes to the placement of the ties or braces, it is best to follow the orthodontist's instructions. The orthodontist will determine the specific positioning based on your individual case and treatment plan. The ties or braces are usually placed around the brackets or bands and are changed periodically during the course of treatment.
