Description

Lip and oral cavity orthodontic appliance

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to lip orthodontic appliance.

Background

In the conventional orthodontic method, the arrangement position of teeth is generally gradually changed by a continuous resilient force applied by an arch-shaped orthodontic wire passing through a bracket adhered to the surface of the teeth. However, the method has many problems, except for the aesthetic problem, the bracket fixed on the tooth has irregular shape and structure, occupies a certain space in the oral cavity, cannot be taken off and worn, affects the daily life and eating experience of a wearer to a certain extent, and the edge of the bracket easily scratches the inner side of the oral cavity and the surface of the tongue, and easily causes a skin-breaking wound to cause oral ulcer.

An appliance which is not required to be adhered to teeth is manufactured by manufacturers to manufacture a sleeve type product according to a tooth shape 3D printing or plastic sheet vacuum forming mode. However, the semi-closed shell structure is easy to accumulate saliva in the interior to cause odor. Because the plastic product has high hardness and the thickness is consistent when the plastic product is worn, the occlusal surface of the product is easily worn and broken by personal habitual problems such as teeth grinding of a user and the like, and the orthodontic effect of the product is influenced. The phenomenon of running water is caused because the oral cavity cannot be normally closed when the product is not in an upper-lower integrated structure and is bitten by a user. Nor is it possible to correct the wearer's mouth breathing habit during use. The method has long process flow, complicated manufacture and long replacement period.

Detailed Description

The invention will be further explained with reference to the drawings and the specific embodiments.

Example 1

As shown in fig. 1 to 4, an orthodontic lip appliance includes an arch rail 1, a lip stop 2, and a tongue stop 3; the dental arch track 1 is a plate-shaped part with the middle part bent forwards, the lip stopper 2 is connected with the front edge of the dental arch track 1, and the tongue stopper 3 is connected with the rear edge of the dental arch track 1; the dental arch track 1, the lip block 2 and the tongue block 3 form a first space for accommodating upper teeth and a second space for accommodating lower teeth together; a tongue top 4 is arranged on one side of the tongue baffle 3 corresponding to the tongue, and an overflow port 5 is arranged at the lower part of the tongue baffle 3; an air duct 6 is arranged between the lip block 2 and the tongue block 3, the air duct 6 is arranged in the dental arch track 1, and air holes 7 are respectively formed on the surfaces of the lip block 2 and the tongue block 3.

The front surface that the lip kept off 2 is equipped with 16 lip pearls 8, and lip pearl 8 is located the outside of lip fender 2 and inclines the below, and is the columnar protrusion, plays the effect of antiskid and suppression active lower lip muscle wearing the in-process.

Lip fender 2 extends to both sides rear from the central line of dental arch track 1 to being close to the position formation that surveys the edge and being used for holding the breach 9 of incisor, carrying out half parcel to incisor and handling and both can not influence just abnormal effect, can also adapt to the growth condition of different back incisor, getting rid of the foreign matter and feel.

The tongue stopper 3 comprises an upper tongue stopper 3a positioned above the dental arch track 1 and a lower tongue stopper 3b positioned below the dental arch track 1; the upper tongue stopper 3a includes a support portion 10 connected to the arch rail 1, and a skirt 11 connected to the support portion 10 and gathered inward.

The tongue top 4 is a semicircular protrusion formed by further extending the outer edge of the middle part of the upper tongue baffle 3a outwards, a circular protrusion particle used for training the correct placing position of the tongue is arranged on the tongue top 4, and the surface of the tongue top is smooth and cannot generate irritation to the tongue.

The overflow port 5 is a notch arranged at the lowest part of the lower part of the tongue baffle 3 and is used for discharging the accumulated saliva in the tongue baffle.

The supporting part 10 and the dental arch track 1 form an included angle of 75 degrees, so that the supporting toughness of the tongue block 3 is improved; the skirt edge 11 and the dental arch track 1 form an included angle of 45 degrees, and a certain angle of inclination can provide a certain amount of movement space for the tongue instead of fixing the tongue at the same position for a long time to cause the feeling of soreness and distension.

Further, as shown in fig. 5, two air ducts 6 are symmetrically arranged on both sides of the center line of the orthosis. The air duct 6 is flat and cylindrical and forms a bulge with the surface of the dental arch track 1, so that the tension of occlusion muscles is avoided, and the occlusion abrasion is not easy to cause; the tongue can keep the balance of internal and external air pressure during wearing, and prevent the generated saliva from causing the adhesion phenomenon between the tongue and the tongue block 3. When the mouth of the wearer is closed and the wearer uses the mask normally, the vent hole 7 can be kept open and not deformed.

As shown in fig. 6, the upper edge and the lower edge of the lip stopper 2 are gradually thinned towards the periphery to form inward-folded arc surfaces, and the inner arc surfaces and the outer arc surfaces are designed according to the arrangement radian of normal teeth and can better fit the surfaces of the teeth in the wearing process.
