[0002] The textbook of pediatric dentistry points out that for children with a high degree of cooperation, the crossbite of individual front teeth can be corrected with a narrow wooden tongue depressor. Children can place the tongue depressor on the palate side of the abnormally positioned tooth and use the cheek as a fulcrum to apply lip force to the affected tooth. This should be done for at least 5 minutes every hour. This method should be used with caution and the indications should be strictly followed under the guidance of a doctor to avoid trauma to the opposing teeth.

[0003] In the process of applying the above-mentioned prior art, the following problems are found:

[0004] (1) Using a narrow wooden tongue bite board can only target one or two teeth, resulting in uneven force and inability to accurately control the force.

[0005] (2) The beneficiary group is children with high demands and who require a high degree of cooperation.

[0006] (3) Frequent daily use poses a problem of disinfection. Currently, the disinfected wooden sticks must be boiled and dried before use. Once the storage environment is too humid or the drying is insufficient, mold is likely to occur, causing great harm to the patient's health.

[0007] Therefore, it is crucial to improve existing corrective devices. Summary of the invention

[0034] The present invention is described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to the following embodiments.

[0035] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0036] 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.

[0037] In the following embodiments, unless otherwise specified, functional components or structures are conventional components or conventional structures used in the art to achieve corresponding functions.

[0038] Embodiment 1:

[0039] like Figure 1-4As shown, a deciduous crossbite corrector whose target group is orthodontic patients with even angles comprises a grip rod 1 and a bite head 2 arranged at one end of the grip rod 1, the bite head 2 comprises a first bite portion 3 connected to the grip rod 1 and used for occluding the maxillary front teeth, a second bite portion 4 connected to the first bite portion 3 and used for positioning the maxillary front teeth, and a third bite portion 5 connected to the first bite portion 3 and used for occluding the mandibular front teeth, and an angle is formed between the second bite portion 4 and the third bite portion 5. The deciduous teeth crossbite corrector provided by the technical solution provides a device for patients to correct the anterior teeth crossbite in real time, by making the maxillary anterior teeth fit the first bite part 3, and the mandibular anterior teeth fit the third bite part 5 away from the root of the outer side of the first bite part 3, at this time, the maxillary anterior teeth do not fit the inner side of the third bite part 5, when the deciduous teeth crossbite corrector is pushed toward the side close to the person, the outer side root is used as a fulcrum, and the main body of the third bite part 5 pushes the maxillary anterior teeth outward, so that the maxillary anterior teeth gradually approach the inner side of the third bite part 5 until they fit, and at the same time, under the limiting effect of the second bite part 4, the maxillary anterior teeth are effectively prevented from sliding out of the first bite part 3 when the deciduous teeth crossbite corrector is pushed. With the help of external force, the upper and lower jaw anterior teeth return to the normal bite position.

[0040] The grip bar 1 is in an arc shape with an arc of 25-40°. For example, the arc of the grip bar 1 is 30°. On the one hand, it is convenient for the patient to hold it, and on the other hand, it is also to increase the safety protection distance to prevent the deciduous crossbite corrector from pressing on the lips during the correction process. The grip bar 1 is a grip bar with a small diameter at both ends and a large diameter in the middle to increase the comfort of the patient's hand. The grip bar 1 is provided with a number of anti-slip stripes to avoid sliding. And the diameter of one end of the grip bar 1 connected to the bite head 2 is smaller than that of the other end, mainly to reduce the direct force brought by the patient during correction and avoid damage to the teeth due to excessive force. In order to connect the second bite part 4 and the third bite part 5 and accommodate the maxillary anterior teeth, the first bite part 3 is in an arc shape, and its height relative to the horizontal plane is 0.1-0.2cm. For orthodontic patients with uniform angles, the angle between the second bite part 4 and the third bite part 5 is 80°. The third bite part 5 is higher than the second bite part 4, so that there is a bite step between the third bite part 5 and the second bite part 4, that is, the height difference between the third bite part 5 and the first bite part 3. For example, the height of the third bite part 5 relative to the horizontal plane is 0.6-1cm, and the height of the second bite part 4 relative to the horizontal plane is 0.3-0.4cm. The height of the bite step just matches the length of the deciduous front teeth, and will not hit the gums during correction, so there is no need to worry about damaging the gums. It is convenient for children to operate simply, and the requirements for the target group are greatly reduced. The bite head is made of silicone material, which is easy to disinfect and has high safety. Its Shore hardness is 50-70 degrees. The thickness of the second bite part 4 and the third bite part 5 is 3-4cm to increase the hardness and avoid deformation. The width of the second bite part 4 and the third bite part 5 is 2-3cm, which can cover 4-5 deciduous front teeth, so that the coverage is wide and the force is even during occlusion, and there is no need to worry about damage to a certain tooth. The bite head 2 and the handle bar 1 are detachably connected or integrally formed. For example, when the bite head 2 and the handle bar 1 are detachably connected, a socket is provided at the bottom of the bite head 2, and a plug rod matching the socket is provided at the end of the handle bar 1 to facilitate replacement of the bite head 2.

[0041] Embodiment 2:

[0042] Compared with the embodiment 1, most of them are the same, except that the angle between the second occlusal portion 4 and the third occlusal portion 5 is 70°, so as to adapt to patients with high average angle of orthodontics, such as Figure 5-6 shown.

[0043] Embodiment 3:

[0044] Compared with the embodiment 1, most of them are the same, except that the angle between the second occlusal portion 4 and the third occlusal portion 5 is 90°, so as to adapt to orthodontic low-angle patients, such as Figure 7-8 shown.

[0045] The above description of the embodiments is to facilitate the understanding and use of the utility model by those skilled in the art. It is obvious that those familiar with the art can easily make various modifications to these embodiments and apply the general principles described herein to other embodiments without creative work. Therefore, the utility model is not limited to the above embodiments, and improvements and modifications made by those skilled in the art based on the disclosure of the utility model without departing from the scope of the utility model should be within the scope of protection of the utility model.
