And the first guide surface 221 , the second guide surface 222 and the inner recess 23 are connected in sequence.

Preferably, the included angle θ can be between 15 degrees and 45 degrees. When the elastic member 40 is wound around, it is easier to slide over and complete the installation, and at the same time, it has better structural strength; of course, the included angle θ is 30 best degree.

The use of the present invention is as follows:

Referring to Figures 1 and 2, the invisible orthodontic brace structure 10 is installed on the plurality of teeth 70, and the at least one fixing member 30 corresponds to the orthodontic auxiliary groove 12 and is fixed to one of the plurality of teeth 70 ( To be corrected), then, the elastic member 40 is wound around the inner concave portion 23 of the at least one mouthpiece protruding hook portion 20 and the at least one fixing member 30 .

The part to be particularly explained here is that, as shown in FIG. 3 , in fact, two of the at least one mouthpiece protruding hook portion 20 are preferably two, which may correspond to the left and right sides of the at least one fixing member 30 , Instead, the correction pushing force P can be generated on one of the plurality of teeth 70 (to be corrected) on both sides on average, so as to perform correction (eg, vertical pull-down).

Referring to FIG. 4, further, the at least one fixing member 30 can also be two, and two of the teeth 70 (to be corrected) can be respectively generated to generate the correction pushing force P to perform correction (for example, vertical pull-up) .

Of course, the foregoing is just an example, and the correction pushing force P may be one of a longitudinal pushing force (longitudinal correction), a lateral pushing force (lateral correction) or an oblique pushing force (oblique correction) depending on the installation position.

The present invention has the following characteristics on installation:

The first feature: the mouthpiece convex hook portion 20 has the guide surface 22, so that the elastic member 40 can slide on the mouthpiece convex hook portion 20 along the guide surface 22 during the installation process, and finally can slide into the mouthpiece convex hook portion 20. The inner concave portion 23 is hooked and fixed, which is the first feature for easy installation.

Second feature: Those in the field of orthodontics know that there is not much space inside the oral cavity, and general orthodontic braces are usually "adhered" to the teeth, so the rubber band (that is, the elastic member 40 in this case) should be hooked to the orthodontic braces. (Usually, the hooks are opened directly on the orthodontic braces), in principle, it is not easy to operate in the gap between the orthodontic braces and the teeth. Aiming at this part, the present invention “protrudes” the mouthpiece hook portion 20 on the outer surface 11 of the invisible orthodontic mouthpiece structure 10 . Such a design allows the installer to have more space without sticking to the mouthpiece. Installation, this is the second feature of easy installation.

The advantages and effects of the present invention can be summarized as follows:

[1] It has a guide surface for easy installation. The mouthpiece protruding hook portion has the guide surface, so that the elastic member can slide on the mouthpiece convex hook portion along the guide surface toward the inner concave portion during the installation process, and finally slide into the inner concave portion. The recessed part is hooked and fixed. Therefore, having a guide surface is easy to install.

[2] The convex hook part of the brace is designed to be convex and easy to install. The protruding hook portion of the mouthpiece is designed to "protrude" on the outer surface of the invisible orthodontic mouthpiece structure, so that the installer can have more space for installation without sticking to the mouthpiece. Therefore, the convex hook portion of the dental brace is designed to be convex for easy installation.

[3] The convex hook part of the braces does not affect the structural strength of the invisible orthodontic braces. The mouthpiece protruding hook portion is attached (fused) to the outer surface of the invisible orthodontic mouthpiece structure by the connecting surface. That is, no cutting or concave joint action is performed on the invisible orthodontic brace structure. Therefore, the convex hook portion of the braces does not affect the structural strength of the invisible orthodontic braces.

[4] It is very convenient to perform horizontal or vertical correction. When there is any single bracket convex part, the corresponding teeth can be corrected laterally, and when two bracket convex parts are provided, they can correspond to the left and right sides of the fixture, and the above-mentioned teeth can be adjusted evenly on both sides. Correspondingly, the tooth is corrected longitudinally. Therefore, it is very convenient to perform horizontal or vertical correction.
