Problems solved by technology

Anterior crossbite is clinically treated by wearing appliances for patients. At present, the commonly used appliances include fixed appliances and removable appliances. The method of wire binding is used for correction. The patient cannot take off the appliance by himself. It is difficult to clean the teeth and periodontal tissue after wearing it. It is easy to cause oral diseases, and there are some restrictions on diet; and the removable appliance It uses movable brackets and steel wires to adjust back and forth to achieve the purpose of correction. Patients of this kind of appliance can take off and wear them freely, and can be taken off when eating and cleaning. It is more convenient to use, but its retention is poor and the correction force is weak, such as Failure to insist on wearing it will affect the therapeutic effect
These two types of orthodontic appliances use the mechanical structure to make the steel wire generate the orthodontic force to pull the teeth and jaws and correct them to the normal position. During the entire long orthodontic treatment process, the patient needs to wear them all day long. , in some public places, it will have a certain impact on the appearance and image of the patient. In addition, the patient needs to go back to the doctor for many times during the treatment process, which is time-consuming and laborious for the doctor.

Embodiment Construction

[0017] The anterior crossbite appliance shown in Figure 1-Figure 4 includes an appliance body made of elastic memory material. The appliance body has a dental arch groove that can be adapted to the lower dental arch of the human body. The dental arch groove has two arches. The groove width of the side parts A and B is adapted to the thickness of the corresponding lower teeth, and the groove width of the middle part C of the arch is greater than the thickness of the lower anterior teeth 8. When the appliance is fastened to the lower dental arch for correction, the lower anterior teeth 8 and the arch The 5 lingual sidewalls of the grooves form the space 9 for moving the lower teeth inwardly, which makes room for the lower front teeth to move to the lingual side after being stressed.

[0018] The appliance is located in the arch-shaped middle part C of the dental arch groove. The inner surface of the groove roof is the inclined guide surface 7 of the lower teeth moving inward with...

Abstract

The present invention relates to an anterior crossbite appliance which comprises an appliance body which is provided with a dental arch slot which matches with the standard lower dental arch of human being. The slot width of the two lateral parts of the arch of the dental arch slot is fit for the thickness of the opposite lower teeth. The middle slot width of the arch of the dental arch slot is larger than the thickness of lower anterior teeth. The inner slot top surface of the middle part of the arch of the dental arch slot is a lower teeth inward shift oblique guide face which is high at the side of tongue and low at the side of lip, and the outer slot top surface at the same position is provided with a bite body which can be covered by upper anterior teeth. A patient can wear the appliance at the lower dental arch directly, when biting spontaneously, the upper anterior teeth of the patient cover the bit body; the bit body pushes the upper anterior teeth upwards and ensures the upper anterior teeth shift towards the side of the lip by forcing the bite force; because the top of the lower teeth inward shift oblique guide face inclines towards the side of the tongue, the bite force pushes the lower anterior teeth inwards by the lower teeth inward shift oblique guide face, the lower anterior teeth is adducted inwards to shift towards the side of the tongue, and the anterior crossbite can be recovered gradually to a normal occlusion by wearing the appliance for long time.

Description

technical field [0001] The invention relates to an appliance used in orthodontic treatment, in particular to an anterior crossbite appliance. Background technique [0002] The normal fit of human teeth is that the upper front teeth cover the lower front teeth. If the lower front teeth cover the upper front teeth, it is deformed. It is called anterior crossbite in medicine, commonly known as "ground cover". Anterior crossbite patients, especially children, if not treated in time, will affect the normal development of the dento-maxillofacial face, resulting in 1 / 3 of the patient's facial underdevelopment resulting in depression, mandibular protrusion, not only affect the face, but also affect the patient's masticatory function Also larger. Anterior crossbite is clinically treated by wearing appliances for patients. At present, the commonly used appliances include fixed appliances and removable appliances. The method of wire binding is used for correction. The patient cannot ...
