Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouthpiece retaining band for preventing the mouthpiece from being detached from a tooth, a mouthpiece used together with the same, and an orthodontic appliance including the same.

[0002]

Mouthpieces attached to teeth are often used for orthodontics and sports. An example of such a mouthpiece is a mouthpiece whose inner peripheral surface is formed based on the shape of teeth.

However, since the mouthpiece is directly attached to the teeth, it may fall off from the teeth. Therefore, the person who uses the mouthpiece must always be careful not to drop the mouthpiece. Furthermore,
For example, when the mouthpiece falls off the tooth, it may bite the mouthpiece, resulting in damage to the mouthpiece.

The present invention has been made in view of the above points, and an object of the present invention is to provide a mouthpiece fall prevention band capable of preventing the mouthpiece from coming off, a mouthpiece, and these. To provide an orthodontic appliance.
