[0019] In this invention, a first arc-shaped surface and a second arc-shaped surface are provided to increase the overall smoothness and reduce the impact of scratching and damage to the skin around the mouth.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model increases the tightness of the fit between the bottom of the connecting cap and the end of the tooth by setting the orthodontic pad. With the cooperation of multiple pressing flaps, it helps to squeeze and correct the teeth. With the cooperation of multiple limiting grooves, it helps to provide a point of force and facilitates the removal and replacement of the connecting cap.

[0022] 2. The present invention, by setting a jaw pad, helps to further increase the force points, making it easier for the connecting cap to be removed from the mouth for fitting. At the same time, with the cooperation of the jaw pad, the stability of the contact between the connecting cap and the oral skin is increased. With the cooperation of the first arc surface and the second arc surface, the smoothness of the overall contact with the oral skin is increased, reducing the impact of friction damage.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please see Figures 1-5 This embodiment provides a technical solution:

[0034] An early orthodontic appliance made of TPU material injection molding includes a connecting cap 1, which is U-shaped and is injection molded from TPU material, with the outer end of the connecting cap 1 being higher than the inner end.

[0035] In this invention, TPU is a thermoplastic polyurethane elastomer rubber, which is injection molded into a connecting cap 1 to increase the durability and flexibility of the connecting cap 1. The outer end is higher than the inner end, which helps to increase the comfort inside the oral cavity and reduces the inner end touching the palate, thus affecting the wearing and use of the orthodontic treatment.

[0036] Furthermore, several limiting grooves 11 are provided on the outer wall of the connecting cap 1 near the middle. The limiting grooves 11 are distributed in a ring at equal intervals, and the depth of the limiting grooves 11 is equal to half the thickness of the outer end of the connecting cap 1.

[0037] In this invention, the cooperation of multiple limiting grooves 11 increases the force points, which helps to separate and remove the connecting cap 1.

[0038] It should be noted that a jaw pad 12 is provided on the inner side wall of the connecting cap body 1 near the top. The jaw pad 12 is in the shape of an arc plate and is integrally formed with the connecting cap body 1.

[0039] In this invention, the jaw pad 12 is provided to increase the point of force, making it easier to remove the whole unit through the jaw pad 12 and providing a point of force. The jaw pad 12 is close to the skin of the upper or lower jaw of the mouth, which increases the stability of the installation and wearing.

[0040] Furthermore, the connecting cap body 1 has a groove 10 in the middle, and the bottom of the groove 10 has an orthodontic pad 2 for contacting the end of the teeth. The width of the inner wall of the groove 10 is adapted to the width of the outer wall of the orthodontic pad 2. The orthodontic pad 2 is U-shaped, and the bottom of the orthodontic pad 2 is bonded and fixed to the bottom of the groove 10.

[0041] In this invention, the installation of the orthodontic pad 2 increases the stability of contact with the tooth tip, thereby increasing the stability of the connecting cap 1 during installation.

[0042] Specifically, the front side of the inner wall of the tooth groove 10 is also provided with several pressing flaps 3.

[0043] Secondly, the pressing flap 3 is semi-cylindrical and distributed in a ring at equal intervals. The pressing flap 3 is bonded and fixed to the corresponding position of the connecting cap 1.

[0044] In this invention, the cooperation of multiple pressing flaps 3 increases the close fit with the teeth of patients of different sizes, thereby achieving the desired effect for orthodontic treatment.

[0045] It is worth adding that the outer end and the inner port of the connecting cap body 1 are both provided with a first arc-shaped surface 13, and the bottom edge of the connecting cap body 1 is provided with a second arc-shaped surface 14.

[0046] In this invention, a first arc-shaped surface 13 and a second arc-shaped surface 14 are provided to increase the overall smoothness and reduce the impact of scratching and damage to the skin around the mouth.

[0047] In this embodiment, the early orthodontic appliance, which is injection molded from TPU material, is used by the user who manually inserts the U-shaped orthodontic pad 2 into the alveolar bone 10 and fixes it in place. The pressing flap 3 is combined with the connecting cap 1 to increase the stability of the connecting cap 1 in contact with the teeth. The jaw pad 12 is combined with the connecting cap 1 to increase the stability of the installation and facilitate the overall replacement.

[0048] The connecting cap 1, injection molded from TPU material, engages with the teeth in the patient's mouth in conjunction with the jaw pad 12. The jaw pad 12 is close to the skin of the upper or lower jaw. With the cooperation of the orthodontic pad 2 and the pressing flap 3, it achieves tooth compression and orthodontic treatment. When it is necessary to remove and replace the whole thing, the cooperation of the limiting groove 11 and the jaw pad 12 helps to facilitate quick removal and replacement. The cooperation of the first arc surface 13 and the second arc surface 14 increases the comfort of wearing and reduces the impact of the connecting cap 1 on oral cavity scratches.
