Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to a dental functional orthodontic appliance used for the treatment of dental occlusion.

``Conventional technology'' In Japan, there is a particularly high incidence of reverse occlusion compared to Western countries, and for this reason, there are many patients who wish to have their reverse occlusion corrected.
Under these circumstances, conventionally, devices such as activators and tin caps have been used. However, these conventional devices have a high age range and are extremely difficult to use from early childhood.
Furthermore, a treatment called the full band system, which involves wrapping bands around all teeth, is not possible for young children. In addition, since it is fixed to the teeth, it has the disadvantage that it tends to make the inside of the oral cavity unclean.

Therefore, it must be said that the above-mentioned conventional techniques have great difficulty in early treatment, which is the fundamental principle of medical care, that is, treatment from infancy.

``Problems to be solved by the invention'' This invention was created in view of the above points, and is applicable to any age group, can be used for early treatment, and is easy to put on and take off, so it is good for oral hygiene. It is also an object of the present invention to provide a preferable orthodontic device.

``Means for Solving Problems'' Therefore, the gist of the present invention is to provide a flat floor body portion whose planar shape is a horseshoe shape corresponding to the row of teeth, and an outer edge of the floor body portion at a portion corresponding to the front teeth. a plate-like protruding piece formed on the upper surface that abuts the outer surface of the gums of the upper jaw; and a band-like protruding part that abuts the inner surface of the lower lip, formed on the lower surface of the outer edge of the area corresponding to the front teeth of the floor main body part; A plate-shaped piece for abutting the tip of the tongue, the upper end of which slightly protrudes from the upper surface of the upper surface of the floor main body and the lower end reaching the inner surface of the gums of the lower jaw, is formed on the inner edge of the area corresponding to the front teeth in the floor main body. This dental functional orthodontic device is made by integrally molding the above from plastic or the like.

Hereinafter, the present invention will be described in more detail with reference to illustrated embodiments.

Figure 1 is a perspective view, Figure 2 is a front view, Figure 3 is a side view, Figure 4 is a plan view, Figure 5 is the middle of Figure 2.
The line sectional view and FIG. 6 are longitudinal sectional side views of the central part of the oral cavity in the installed state.

In the figure, reference numeral 1 denotes a floor main body portion whose planar shape is a horseshoe shape corresponding to the row of teeth. Reference numeral 2 denotes a plate-shaped projecting piece formed on the upper surface of the outer edge of a portion A corresponding to the front teeth in the bed main body 1, and comes into contact with the outer surface of the gums of the upper jaw. Further, the height of the plate-like projecting piece 2 is appropriately determined depending on the patient. Further, the plate-like projecting piece 2 is curved to fit the gums. Reference numeral 3 denotes a band-shaped protrusion formed on the lower surface of the outer edge of the portion A corresponding to the front tooth portion in the floor body portion 1, and comes into contact with the inner surface of the lower lip. 4 is a portion A corresponding to the front teeth in the floor body portion 1
This is a plate-shaped piece formed on the inner edge of the tongue, and by bringing the tip of the tongue into contact with this, it prevents the tip of the tongue from coming into contact with the gums of the lower jaw. Further, the upper end 4' of the plate-shaped piece 4 slightly protrudes from the upper surface of the floor body 1 and comes into contact with the inner surface of the front teeth, and the lower end 4'' protrudes to a position reaching the inner surface of the gums of the lower jaw.5. is a rod-shaped knob that protrudes from the outer surface of the central portion of the plate-shaped piece 2, and has a string insertion hole 6 at its tip.

In the present invention, the floor body part 1, the plate-like projection part 2, the protruding part 3, the plate-like part 4, and the knob 5 are integrally molded from plastic, wax, or the like. Additionally, these surfaces are smooth to provide a good feel to the touch.

In addition, in the drawings, 7 and 8 are the front teeth, 9 is the upper jaw gum, 10 is the lower jaw gum, 11 is the upper lip, 12 is the lower lip, and 13 is the tongue.

"Operation" Next, the operation of the present invention having the above configuration will be explained.

Open your mouth, pick knob 5, and insert the present invention into your mouth. Then, the patient bites the main body part 1 between the front teeth 7 and 8 from above and below, and closes the upper lip 11 and the lower lip 12, thereby placing the present invention in the oral cavity. In this worn state, the plate-like projecting piece 2 is in contact with the outer surface of the gums 9 of the upper jaw, and the projecting part 3 is in contact with the inner surface of the lower lip 12. Furthermore, the upper end 4' of the plate-like piece 4 is in contact with the inner surface of the front teeth 7 of the upper jaw.

When the present invention is thus installed in the patient's oral cavity, it is possible to correct a reverse occlusion by a completely different action from that of conventional orthodontic devices.

In other words, the present invention is not based on the concept of correcting the upper and lower jaws by holding and fixing them in their normal positions, as is the case with conventional appliances, but by taking this idea further, it is possible to treat patients with reverse occlusion in a state similar to that of protruding teeth. It attempts to correct this by creating a

To explain more specifically, when the plate-like protruding piece 2 comes into contact with the outer surface of the gums 9 of the upper jaw with moderate pressure, overstrain of the cervix muscle occurs, and at the same time, the plate-like protruding piece 2 causes the upper lip 11 and the upper jaw to tighten. contact of the gums 9 is prevented and tension in the orbicularis oris muscle is removed. Furthermore, in patients with reverse occlusion, the tip of the tongue is always in contact with the gums of the lower jaw, but this is prevented by the plate-like piece 4, and the tip of the tongue is brought into contact with the gums of the upper jaw. .
In this way, a condition similar to so-called protruding teeth is created and corrected.

By doing so, the position of the mandible can be guided to a functionally normal position within a short period of time.

"Effect of the invention" Since the present invention has the above-mentioned structure and operation, the applicable age is not limited and it can be used for early treatment. Moreover, since it is easy to put on and take off, it can be easily taken off when brushing teeth, which is also preferable in terms of oral hygiene. In addition, the correction period can be significantly shortened compared to conventional correction devices, and the cost burden on patients can be significantly reduced. In particular, if the present invention is used in the same way as wet-wetting for infant patients, it can be corrected without causing any pain. Furthermore, when used on young children, the powder can be prevented from being lost by passing a string through the string insertion hole provided in the knob and letting it hang around the neck. Furthermore, since the present invention is integrally molded from plastic or the like,
It can be manufactured at low cost and has many practical applications and benefits.
