Description

Tooth chewing device {TOOTH CHEWING DEVICE}

The present invention is interposed between both teeth in a state in which a transparent orthodontic device is bonded to at least one of both upper and lower teeth, to improve the bonding between the teeth and the transparent orthodontic device through a chewing motion of both teeth It relates to a tooth chewing device.

The transparent orthodontic appliance is called an aligner or a trade name of Invisalign, and is formed in the form of a mouthpiece made of a thin and transparent plastic material.

Transparent orthodontic devices can correct teeth without using wires and brackets and give a good appearance, so they have been widely used recently.

Recently, in order to wear a transparent orthodontic appliance on at least one of the upper and lower teeth, the upper jaw between the upper and lower teeth to which the transparent orthodontic appliance is not mounted and the transparent orthodontic appliance worn on both sides A tooth chewing device has been developed that induces chewing motion between teeth and lower teeth to improve bonding properties of a transparent orthodontic appliance. These tooth chewing devices are also called Chewies.

Dental chewing devices are, in principle, disposable consumables, but are often used continuously for a long period of time in the oral cavity during the period of wearing the device for orthodontic treatment, so hygiene is a concern.

In addition, the conventional tooth chewing device is manufactured in a short straight shape and does not reach the posterior teeth when inserted into the oral cavity, or when an additional wing or attachment is designed on the buccal side, it is not easy to reach the desired part.

In addition, the conventional tooth chewing apparatus has a problem in that slip occurs due to lack of frictional force during chewing motion between the upper teeth and the lower teeth.

In addition, since the handle is not designed separately, there is a problem in that it is transmitted to the wearer as droplets or saliva in the oral cavity during insertion or discharge into the oral cavity.

In addition, the conventional orthodontic appliance has a problem in that there is no clinical guideline for shelf life, disposal period, or sterilization possibility.

Let's explain.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view showing a state in which a dental chewing device according to a first embodiment of the present invention is provided between a transparent orthodontic device mounted on lower teeth and upper teeth, and FIG. 2 is a tooth according to a first embodiment of the present invention It is a perspective view showing the chewing device.

As shown in FIGS. 1 and 2 , the tooth chewing device according to the first embodiment of the present invention includes a chewing body 100 and a concave-convex portion 200 .

The chewing body 100 is provided between the transparent orthodontic device 10 mounted on the lower teeth 2 and the upper teeth 1, and performs chewing motion of the upper teeth 1 and the lower teeth 2. induce However, in the present embodiment, the transparent orthodontic device 10 is shown as being worn on the upper teeth 1 and not worn on the lower teeth 2, but is not limited thereto, and the transparent orthodontic device 10 may be worn on the lower teeth It may be worn on (2) and not worn on the maxillary teeth (1).

In this way, when the chewing motion of the upper teeth 1 and the lower teeth 2 is induced by the chewing body 100, as the transparent orthodontic device 10 moves toward the upper teeth 1, the transparent orthodontic The fitability of the device 10 may be improved.

In this embodiment, the chewing body 100 may have a rectangular plate shape.

The chewing body 100 may include a chewing unit 110 provided in one area of the chewing body 100 and a gripping unit 120 provided in another area of the chewing body 100 .

The chewing unit 110 may engage between any one of the upper teeth 1 and the lower teeth 2 to which the transparent orthodontic appliance 10 is not mounted and the transparent orthodontic appliance 10 . Here, the chewing unit 110 may be formed in a rectangular shape and may be engaged with the front teeth.

The chewing unit 110 may further include a buffer groove 112 for buffering a load acting on the chewing unit 110 according to a chewing motion.

The buffer groove 112 may be hollow inside the chewing unit 110 along the longitudinal direction. Therefore, during a chewing motion, the outer surface of the chewing unit 110 is pressed toward the buffer recess 112, and the load acting on the chewing unit 110 can be buffered. For example, the buffer groove 112 has a rectangular cross-sectional shape, but is not limited thereto, and the buffer groove 112 may have a circular, elliptical, or polygonal cross-sectional shape.

The holding portion 120 is for holding the chewing body 100 and may extend from the chewing portion 110 . This gripping part 120 may be formed in a rectangular shape. In addition, a gripping hole 122 for facilitating gripping may be formed through the gripping portion 120 .

The concavo-convex portion 200 is provided on the chewing body 100 to face the transparent orthodontic device 10, and serves to prevent the transparent orthodontic device 10 from slipping during chewing motion. Specifically, during a chewing motion, the concavo-convex portion 200 secures frictional force between the transparent orthodontic appliance 10 and the chewing body 100, thereby preventing slip between the transparent orthodontic appliance 10 and the chewing body 100. can

In this embodiment, the concave-convex portion 200 has a straight line shape with a certain width, and may be disposed at intervals along the longitudinal direction of the chewing body 100 . Here, the uneven portion 200 may be formed in a plate shape.

Meanwhile, the tooth chewing device according to the first embodiment of the present invention may include an information display unit 300 .

The information display unit 300 may be provided on the chewing body 100 to display information related to the expiration date, disposal date, or disinfection possibility of the chewing body 100 .

As shown in FIG. 3, unlike the first embodiment, in the tooth chewing device according to the second embodiment of the present invention, the uneven portion 200' has a curved arc shape, and the curved area is the chewing body 100 ) may be disposed at intervals in the same direction along the longitudinal direction of the ), or may be disposed intersecting each other in opposite directions.

Here, when the concavo-convex parts 200' are disposed crossing each other in opposite directions, a pair of concave-convex parts 200' adjacent to each other may have a concave arc shape in a direction away from each other. One of these parts of the transparent orthodontic appliance 10 may be inserted between the pair of convex-convex portions 200′ adjacent to each other. Therefore, in this embodiment, the frictional force between the transparent orthodontic appliance 10 and the concavo-convex portion 200' can be further improved.

Meanwhile, the tooth chewing device according to the first and second embodiments of the present invention is preferably used by middle-aged people in their 30s to 60s. In the case of the middle-aged, orthodontic treatment is often performed concurrently with other dental treatments such as prosthesis and restoration of missing teeth. In addition, the transparent orthodontic appliance 10 may not cover the anterior row of teeth or may be made in an asymmetric setting. Furthermore, even if the transparent orthodontic appliance 10 includes an anterior row of teeth, there are a number of cases in which a strong force should not be applied or a missing area without teeth. Therefore, the forms of the first and second embodiments that distribute a little more flexible force than the form of giving concentrated force in a small form are recommended.
