According to the adjustable orthodontic mouth gag disclosed by the invention, the adjustable molar area support wings are arranged on the auricles to unfold the buccal mucosa of the molar area, so that the binding of orthodontic attachments of a posterior tooth area is facilitated; the supporting strength of the buccal mucosa of the molar area can be adjusted, the operations can be facilitated, and the discomfort in the operation of the mouth gag can be minimized at the same time.

Description

A kind of adjustable oral cavity correction gag

Technical field

The present invention relates to the medical apparatus and instruments that a kind of oral cavity is used, relate in particular to a kind of adjustable oral cavity correction gag.

Background technology

In mouth cavity orthodontic is clinical, gag is a kind of aid of conventional bonding bracket.In order to reach best rectifying effect, often need to be at the second permanent molar correction adnexa that even bonds above third molar; But the gag of application is mainly the lip buccal mucosa that struts front portion, oral cavity at present, to grinding one's teeth in sleep, district's mucosa does not almost support, thereby cause second permanent molar and third molar buccal tube and other adnexaes be difficult to accurately, smoothly, firmly in place, thereby affect carrying out smoothly of orthodontic therapy.

There is part doctor to take the method for second permanent molar or third molar bonding band to reduce and rescue coming off of adnexa.But application band exists the problem of difficulty in place, accurate difficulty in place equally, meanwhile, application band is larger to the stimulation of buccal mucosa, rescues rear easy generation food impaction.

Summary of the invention

For above shortcomings in prior art, the invention provides and a kind ofly can in strutting the anterior lip buccal mucosa in oral cavity, strut the buccal mucosa in the district of grinding one's teeth in sleep, thereby be beneficial to the adjustable oral cavity correction gag of the district's bonding correction adnexa of grinding one's teeth in sleep.

In order to solve the problems of the technologies described above, the present invention has adopted following technical scheme:

A kind of adjustable oral cavity correction gag, comprises oral cavity front support device and the adjustable district's braced wing of grinding one's teeth in sleep;

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.

As shown in Figure 1, a kind of adjustable oral cavity correction gag, comprises oral cavity front support device and the adjustable district's braced wing of grinding one's teeth in sleep.

Wherein, oral cavity front support device comprises connecting rod 1 and two auricles 2, and connecting rod 1 is arcuate structure, and connecting rod 1 is a connection thin plate, and the sidepiece of two auricles 2 connects by connecting rod 1 and forms an entirety, and two auricles 2 and connecting rod 1 are made into integration.The structure of auricle as shown in Figure 2, auricle 2 is made up of the large wing 21 of auricle and auricle winglet 22, the large wing 21 of auricle and auricle winglet 22 are stacked on top of one another layout (be the top that the large wing 21 of auricle is positioned at auricle winglet 22, the large wing 21 of auricle and auricle winglet 22 form the U-shaped structure of lateral opening).On the large wing 21 of auricle, place hole I23 and place hole II24 are set, place hole I23 is near the outside of the large wing 21 of auricle, and place hole II24 is near the inner side of the large wing 21 of auricle.The relative both sides of place hole II24 arrange respectively pipe 25 in place.Connecting rod 1 on the front support device of oral cavity has certain elasticity, the large wing 21 of auricle on the front support device of oral cavity and auricle winglet 22 can be between two auricles 2 or the outside curve of two auricles 2 in the time of the compressing being subject to by ambient pressure, in the time that external pressure disappears, two auricles 2 return to original position again.

The structure of the adjustable district's braced wing of grinding one's teeth in sleep as shown in Figure 3, the adjustable district's braced wing of grinding one's teeth in sleep is the U-shaped bar 3 of an elasticity, in the present embodiment, the U-shaped bar 3 of this elasticity adopts elastic stainless steel silk to make, the two ends difference of the U-shaped bar of elasticity in the opposite direction outward forms joint end 31, the both sides of the U-shaped bar 3 of elasticity at least arrange respectively a dynamics and regulate spring 32, and dynamics regulates the quantity of spring 32 to determine according to the size that regulates the support degree to the district's buccal mucosa of grinding one's teeth in sleep.Dynamics regulates spring 32 to bend to annulus by one section in the U-shaped bar 3 of elasticity and forms, and in the present embodiment, only need clip stainless steel silk with needle-nose pliers, and firmly rotation just can form an annulus.

A U-shaped bar 3 of elasticity is set respectively on each auricle 2, and the inward at both ends of the U-shaped bar 3 of elasticity is through place hole I23, and the two ends of the U-shaped bar 3 of elasticity penetrate place hole II24 and are stuck in corresponding pipe in place 25; The outside of the large wing 21 of auricle is stretched at the middle part of the U-shaped bar 3 of elasticity, and the middle part of the U-shaped bar 3 of elasticity refers to the section of arching upward, and the middle part of the U-shaped bar 3 of elasticity is protruding along the upper surface of the large wing 21 of auricle, and it is vertical with pipe 25 in place to prolong the direction.This adjustable grinding one's teeth in sleep when district's braced wing is installed, the both sides of the U-shaped bar 3 of available hands extruding elasticity, the both ends openings get smaller of the U-shaped bar 3 of elasticity; Then the place hole I23 on the large wing 21 of auricle is passed in the below of the both ends of U-shaped elasticity bar 3 large wing 21 of direction auricle from the large wing 21 of auricle, then the both ends of U-shaped elasticity bar 3 are penetrated in place hole II24, the joint end 31 on the both ends of the U-shaped bar 3 of elasticity is snapped in corresponding pipe in place 25.

The U-shaped bar 3 of elasticity stretches out the end in the large wing of auricle 21 outsides apart from the lateral surface 2.0-2.8mm of the large wing 21 of auricle, the extended distance that the U-shaped bar 3 of elasticity is positioned at the large wing of auricle 21 outsides is 1.5-2.5mm, boss on the U-shaped bar 3 of elasticity can be semicircle, also can make half elliptic, the U-shaped bar 3 of elasticity under this size all can adapt with the shape of buccal mucosa.

Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although the present invention is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement technical scheme of the present invention, and not departing from aim and the scope of technical solution of the present invention, it all should be encompassed in the middle of claim scope of the present invention.
