[0026] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] Example

[0028] The present embodiment provides an orthodontic appliance for use in the deciduous dentition period or the replacement dentition period, comprising a left base 1, a right base 2, and a hyperbolic labial bow 3, wherein two ends of the hyperbolic labial bow 3 are respectively connected to the left base 1 and the right base 2, and the left base 1 and the right base 2 are connected via an expander 4, and the expander 4 is used to adjust the gap between the left base 1 and the right base 2;

[0029] Long arrow cards 5 are provided on both the left base 1 and the right base 2; the long arrow cards 5 are located on two deciduous molars, or on the first permanent molar or the second deciduous molar;

[0030] Both the left base 1 and the right base 2 are also provided with interproximal hooks 6; when the long arrow card 5 is located on the two deciduous molars, the interproximal hook 6 is located between the two deciduous molars; when the long arrow card 5 is located on the first permanent molar and the second deciduous molar, there are two interproximal hooks 6, one interproximal hook 6 is located between the first permanent molar and the second deciduous molar, and the other interproximal hook 6 is located between the deciduous canine and the first deciduous molar; the appliance in this embodiment is used to correct dental anterior open bite cases caused by bad habits such as tongue sticking out and mouth breathing in children. When the appliance in this embodiment is used for children in the deciduous dentition period, the appliance is retained by the long arrow cards 5 in the bilateral deciduous molar areas and the interproximal hook 6 in the middle; when the appliance in this embodiment is used for children in the dentition replacement period, the appliance is retained by the long arrow card 5 in the first permanent molar and the second deciduous molar area, the interproximal hook 6 between the two teeth, and an additional interproximal hook 6 located between the deciduous canine and the first deciduous molar.

[0031] The left base 1 and the right base 2 are also provided with a posterior teeth area jaw pad 8 corresponding to the position of the maxillary posterior teeth area. The posterior teeth area jaw pad 8 at least partially wraps the maxillary posterior teeth. The thickness of the posterior teeth area jaw pad 8 is 3-4mm, and the surface of the posterior teeth area jaw pad 8 close to the opposite jaw is provided with a silicone layer with a thickness of 0.2mm-0.6mm. In this embodiment, by providing a jaw pad in the posterior teeth area, the adverse effects of the buccal tilt of the posterior teeth, the drooping of the tongue tip, the increase of the posterior teeth height, and the unfavorable correction of the anterior teeth opening and closing caused by the expansion of the arch can be effectively reduced. In addition, the addition of the posterior teeth area jaw pad 8 can also utilize the masseter muscle strength during eating and resting, and at the same time increase the masseter muscle training, which can play the role of lowering the posterior teeth and improving the opening and closing of the anterior teeth; further, in this embodiment, a silicone layer with a thickness of 0.2mm-0.6mm is provided on the surface of the posterior teeth area jaw pad 8 close to the opposite jaw, which can further improve the patient's bite comfort.

[0032] Furthermore, the first end of the interproximal hook 6 in the present embodiment is embedded in the left base 1 or the right base 2, and the second end of the interproximal hook 6 is provided with a ball clip. By adding the ball clip to the second end of the interproximal hook 6, the possibility of damaging the gums when the orthodontic appliance is worn can be effectively reduced, thereby increasing wearing comfort.

[0033] In this embodiment, the left base 1 and / or the right base 2 are provided with a tongue grille 7, wherein the tongue grille 7 is fence-shaped. When both the left base 1 and the right base 2 are provided with tongue grilles, the tongue grille 7 on the left base 1 and the tongue grille 7 on the right base 2 are separated and not connected.

[0034] The expander 4 in this embodiment is a spiral expander 4 .

[0035] In this embodiment, the number of long arrowheads 5 and interproximal hooks 6 mainly depends on the number of molars. For example, when the child to be treated is in the primary dentition period, Figure 3 As shown, there are two molars, and one long arrow card 5 can be set, located on two deciduous molars (the first deciduous molar and the second deciduous molar), and an interproximal hook 6 is added between the two molars; when the maxillary first permanent molar erupts, as shown Figure 4 As shown, the number of molars is 3, and the number of long arrow clips 5 can be set to 1, which is located on the last two molars (the second deciduous molar and the first permanent molar). The number of interproximal hooks 6 can be increased to 2, one of which is located between the last two molars (the second deciduous molar and the first permanent molar), and the other is located between the deciduous canine / permanent canine and the first deciduous molar, so as to improve the retention force of the orthodontic appliance.

[0036] In this embodiment, both ends of the long arrow card 5 are embedded in the corresponding base, and the hanging part of the long arrow card 5 is located on the outside of the corresponding base.

[0037] In this embodiment, the left base 1 and the right base 2 are both made of resin, and the long arrowhead clip 5 and the interproximal hook 6 are both bent from stainless steel wire.

[0038] In one embodiment, tongue grids 7 are provided on both the left base 1 and the right base 2. The two tongue grids 7 are fixed on the left base 1 and the right base 2 respectively, and the lengths of the two tongue grids reach 1 / 3 of the inner gum of the lower front teeth, so as to correct the habit of tongue sticking out and swallowing. The thickness of the bilateral posterior teeth area jaw pads 8 is about 3-4mm, which is higher than the resting space, and can lower the posterior teeth during functional movements such as chewing and swallowing, and during rest. At the same time, the wrapping effect of the posterior teeth area jaw pads 8 on the molars can reduce the side effects of molar buccal tilt, tongue tip drooping, and increased bite height caused by arch expansion to a certain extent.

[0039] The appliance in this embodiment is usually worn on the upper jaw. When it is worn on the lower jaw, it is necessary to use the mandibular expansion lip arch corrector under the condition that the special tongue-sticking habit causes the lip inclination of the lower front teeth, and the upper jaw also needs to be used in conjunction with the maxillary jaw pad expansion tongue grid corrector.

[0040] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art can make various changes or modifications within the scope of the claims, which does not affect the essence of the present invention. In the absence of conflict, the embodiments of the present application and the features in the embodiments can be combined with each other at will.
