Abstract

The utility model relates to an anterior crossbite oral appliance which comprises an oral appliance body, wherein, the oral appliance body is provided with a dental arch groove which is matched with the body standard lower dental arch, the groove width of the two arch sides of the dental arch groove is compatible with the thickness of the corresponding lower teeth, the groove width of the arch middle part of the dental arch groove is larger than the thickness of the lower anterior teeth, the inner surface of the groove top of the arch middle part of the dental arch groove is a lower dental ingression bevel guide surface with higher tongue side and lower lip side, the outer surface of the groove top of the same part is provided with an occlusion body covered by the upper anterior teeth. A patient can directly put the oral appliance on the lower dental arch. When the patient occludes naturally, the upper anterior teeth of the patient cover the occlusion body. By applying an occlusion force, the occlusion body forms an outward thrust on the upper anterior teeth to make the upper anterior teeth move toward the lip side. Because the lower dental ingression bevel guide surface inclines toward the tongue side, the occlusion force forms the inward thrust on the lower anterior teeth through the lower dental ingression bevel guide surface. The lower anterior teeth are adducted to move toward the tongue side, therefore, the long-time wearing and rectification of the oral appliance can enable the anterior crossbite tp recover.

Description

Anterior teeth unusual occlusion appliance

Technical field

This utility model relates to the appliance that uses in the orthodontic treatment, especially a kind of anterior teeth unusual occlusion appliance.

Background technology

Human teeth's normal occlusion is that Upper Anterior Teeth covers labial teeth down, if down labial teeth to cover Upper Anterior Teeth then be lopsided, labial teeth is counter to be closed medically being referred to as, and is commonly called as " Bao Tian ".If the anti-patient of closing of the labial teeth especially untimely treatment of child patient can influence the normal development of tooth jaw cranium face, cause that 1/3 deficiency of development produces depression in patient's face, prognathism not only influences face, and also bigger to patient's masticatory function influence.Counter being combined in clinically of labial teeth carried out orthodontic treatment by wear appliance to the patient, at present, appliance commonly used has fixed appliance and removable appliance, fixed appliance is to adopt fixed support to add the plane to close pad, correct with the mode of ligation silk binding, this appliance patient can not take off voluntarily, wear and use the back difficult, cause oral disease easily, and on diet, also can be subjected to some restrictions the cleaning of tooth and periodontal tissue; And removable appliance is to adopt travel(l)ing rest, utilize steel wire to adjust back and forth again to reach corrigent purpose, and this kind appliance patient can freely pluck and wear, and has a meal, can take off when cleaning, use more convenient, but its maintenance is relatively poor, and it is on the weak side to rescue power, wears with influencing therapeutic effect as not adhering to.This two classes appliance all is to make the steel wire generation rescue power by frame for movement to come tooth, jawbone are carried out tractive, be remedied to the normal occlusion position, in whole very long orthodontic treatment process, all need patient's whole day to wear usefulness, like this, will patient's appearance and image be affected in some public arenas, in addition, also need repeatedly further consultation regularly of patient in the therapeutic process, the doctor is wasted time and energy.

The utility model content

The purpose of this utility model provide a kind of patient can pluck voluntarily wear, repeatedly further consultation and do not need whole day to wear the anterior teeth unusual occlusion appliance of usefulness in therapeutic process.

For achieving the above object, this utility model adopts following technical scheme: anterior teeth unusual occlusion appliance, comprise the appliance body, the appliance body have can be adaptive with human body standard lower dental arch the dental arch groove, the groove width of the arc two side portions of dental arch groove adapts with the thickness of corresponding lower tooth, the groove width at the arc middle part of dental arch groove is greater than the thickness of following labial teeth, the groove top inner surface at the arc middle part of dental arch groove is to move oblique surface in the low lower tooth of the high lip side of tongue side, and the groove top outer surface at same position is provided with the interlock body that can be covered by Upper Anterior Teeth.

Position near the groove top on the tongue sidewall outer surface at the arc middle part of dental arch groove has horizontal buffering slit.

Described interlock body is the snap protrusions that is disposed on side by side on the outer surface of groove top.

The lip side wall inner surfaces at the arc middle part of dental arch groove is provided with horizontal reinforcing bow line.

Lateral separation cloth spinosity labium minora on the lip sidewall outer surface at the arc middle part of dental arch groove.

The appliance body is made by the elastic memory material.

This utility model adopts the dental arch trench structure, the groove width of the arc two side portions of dental arch groove adapts with the thickness of corresponding lower tooth, and the groove width at arc middle part is greater than the thickness of following labial teeth, like this when appliance fastens on the lower dental arch, following labial teeth is near the lip sidewall, cusp is against the intersection that moves oblique surface in lip sidewall and the lower tooth, has then formed between the tongue sidewall of infra labial teeth and arcuate slots and has moved the space in the lower tooth, for the stressed back of following labial teeth provides the space to the tongue side shifting.During rectification, the patient can directly be worn over this appliance button on the lower dental arch, when natural interlock, patient's Upper Anterior Teeth covers the interlock body, by applying gmatjpdumamics, the interlock body has formed outside thrust to Upper Anterior Teeth and has made Upper Anterior Teeth labiad side shifting, owing to move the oblique surface top to linguoclination in the lower tooth, gmatjpdumamics by move in the lower tooth oblique surface to dentification before down inside thrust, in accept labial teeth and make it to the tongue side shifting, wear rectification and can make counter the closing of labial teeth progressively return to normal occlusion by secular like this.

In this utility model, it is in order to make the interlock body portion have certain elasticity that the buffering slit is set, gingiva in the painful upper jaw in interlock body top when preventing that gmatjpdumamics is excessive; Adopt the interlock body of snap protrusions form, can make the interlock body have higher intensity, be convenient to apply gmatjpdumamics; Afterburning bow line is in order to have increased the intensity of lip sidewall, to have applied light power to following labial teeth, having made it to obtain to correct; The effect of thorn labium minora is when jaw flesh excess shrinkage, and friction stimulates mucosa in the lip, notes slowing down contraction to remind the patient, helps to correct the mandibular protraction that is caused by bad oral habit, helps to improve the face form.This appliance is made by the elastic memory material, after wearing, the traction force that appliance body generation elastic deformation produces can substitute fixed appliance and add steel wire tractive tooth with support, thereby avoided numerous and diverse program of configuration fixed appliance, do not need to install travel(l)ing rest adjustment back and forth yet, just can reach the rectification purpose by life-time service so this appliance once disposes the back that is shaped, and not need repeatedly further consultation, doctor and patient is all laborsaving easy.

This utility model belongs to can pluck the appliance of wearing voluntarily, and the patient keeps wearing the regular hour every day and gets final product, and wears usefulness without whole day, thereby can patient's image not impacted.In addition, existing appliance generally is just can wear in the time of 12 years old the patient to rescue, and missed the best period of orthodontics, and this appliance can just be corrected after preceding four the permanent teeth eruptions of child, thereby can not have influence on the normal development of child's face.
