DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an occlusal correction plate for assisting occlusal correction and a occlusal correction method using the plate.

[0002]

2. Description of the Related Art If the bite of a tooth is not normal, the function of the brain is reduced, and if the condition is prolonged, various medical conditions occur. Such a condition is referred to as low occlusion syndrome, and there are more than 150 conditions that are currently confirmed. However, the low bite syndrome is one of the most serious diseases for human beings, since modern people with normal bite are extremely rare.

[0003] When the occlusion is normal, the jaw is at the center as shown in Fig. 3 and the teeth are eccentrically engaged at the midline. To examine abnormalities of the temporomandibular joint, observe the opening and closing movement of the lower jaw and the state of the upper and lower teeth biting. If the bite is abnormal, the mouth opens and closes awkwardly, as shown in FIG.
The jaws show a distinct deviation to one or the other. These abnormalities are related to the muscles that control jaw movement (massic muscle, temporal muscle, medial and lateral pterygoid muscles)
It is caused by imbalance such as.

[0004]

[Problems to be solved by the invention]
Normally, an occlusal correction mouthpiece carefully prepared by a dental professional according to the patient's tooth shape and dentition is worn in the patient's mouth. However, conventional mouthpieces are expensive and difficult to obtain in remote areas without dental specialists.

Accordingly, the present invention provides an occlusal correction plate which can be manufactured easily and inexpensively and which can be used easily, and a occlusal correction method using the plate.

[0006]

According to the occlusal correction plate of the present invention, a marker serving as a mark for aligning the midline of the upper and lower dentitions is formed on the plate body sandwiched between the upper and lower dentitions. Things. Such an occlusal sandwiching plate is provided with a muscle caused by forward and backward movement, left and right movement or rotational movement of the head while being bitten by the upper and lower teeth so that the midline of the upper and lower teeth is aligned with the marker as a mark. Use it to do stretching exercises.

As described above, the muscle stretching of the head is performed in a state of normal occlusion in which the dentitions of the upper and lower jaw lines are aligned, so that the masseter muscle, the temporal muscle, and the medial-lateral pterygoid muscle that control the movement of the jaw are performed. Etc. become the original tension state, and the muscle balance can be adjusted.

It is desirable that the plate body sandwiches the flat plate with an elastic material. The flat plate is made of a hard and lightweight material such as wood or plastics, and is sandwiched between elastic materials such as silicon rubber. When such a plate body is chewed by the upper and lower dentition,
By interposing the elastic body without directly contacting the flat plate, the force applied to the teeth can be reduced. Further, since the quality of the elastic material such as silicone rubber does not change even if it is washed, such an occlusal holding plate is kept clean.

At this time, it is desirable that the marker is formed on the surface of the flat plate and the elastic material has transparency. As a result, the marker is protected in a visible state by the transparent elastic material, and the marker does not disappear even if it is repeatedly used in the oral cavity. Further, when various colors are used for the flat plate, the colors can be seen from the outside by an elastic material having transparency, and the aesthetic appearance is also excellent.

[0010]

FIG. 1 is a perspective view of an occlusal correction plate according to an embodiment of the present invention, and FIG. 2 is a front view showing a use state of the occlusal correction plate of FIG.

As shown in the figure, the occlusal correction plate in the present embodiment is mounted on a plate body 1 having a plastics plate 3 having a thickness of about 3 mm sandwiched between silicone rubbers 2a and 2b each having a thickness of about 1 mm as an elastic material. The marker 4 is formed as a mark for aligning the midline 6 of the tooth rows 5a and 5b of the upper and lower jaws, respectively.

The silicone rubbers 2a and 2b have transparency, and the surface of the flat plate 3 can be seen through the silicone rubbers 2a and 2b. In addition, as the elastic material, a material having similar properties can be used in addition to the silicone rubbers 2a and 2b. Marker 4
This is a line formed at the center in the longitudinal direction of the flat plate 3 over the entire surface thereof, and is a transparent silicone rubber 2a, 2
protected by b.

The user of such an occlusal correction plate is:
The midline 6 of the upper and lower teeth 5a, 5b is aligned with the marker 4 toward a mirror or the like. At this time, if the marker 4 formed on the upper surface 3a or the lower surface 3b of the flat plate 3 is inserted into the oral cavity while visually confirming the position, the marker 4 of the occlusal correction plate becomes almost near the midline 6 of the dentition 5a, 5b. Placed in Then, the marker 4 formed on the front surface 3c of the flat plate 3 is photographed by a mirror or the like, and the position of the photographed marker 4 is visually confirmed while the upper jaw is adjusted so that the median line 6 of the tooth rows 5a and 5b is aligned with the marker 4. And adjust the position of the lower jaw.

Thus, the upper and lower dentitions 5a, 5b
The occlusal correction plate is gripped while the midline 6 is aligned with the marker 4, and the head is stretched by a back and forth movement, a left and right movement or a rotation movement of the head in the state as it is. Upper and lower dentitions 5a, 5
When the midline 6 of b is aligned, the masseter muscle that controls the movement of the jaw,
The temporal muscles, the medial and lateral pterygoid muscles, etc. are in their original tension. When the muscle stretching exercise of the head is performed in the state of normal occlusion as described above, the above-mentioned muscle groups gradually become equal in length to the left and right, and the muscle balance is adjusted.

As a result, one-sided stretching and tension of muscles are improved, and illness caused by a decrease in brain function can be improved. In addition, the muscles of the whole body also have almost equal length and muscle strength on the left and right, improving athletic ability appearing in reflexes and dexterity, improving physical ability appearing in strength of muscles and good muscle balance, learning ability , Thinking ability and concentration ability can be improved. Such an occlusal correction plate can be easily and inexpensively manufactured by using a plastics flat plate 3, silicon rubbers 2a, 2b, and the like. It is very easy to simply perform a muscle stretching exercise by adjusting the midline 6 of FIG.

According to the occlusal orthodontic plate of the present embodiment, the plate body 1 is connected to the upper and lower jaw teeth 5.
When biting by the a and 5b, the force applied to the tooth rows 5a and 5b can be reduced through the soft silicone rubbers 2a and 2b without directly contacting the hard flat plate 3. Also, the tooth rows 5a, 5b are made of silicone rubber 2a, 2b.
Since the plate body 1 is sandwiched while being sunk, the midline 6 of the tooth rows 5a and 5b does not shift during the muscle stretching exercise. At this time, the molds of the tooth rows 5a and 5b remain in the silicone rubbers 2a and 2b, but if they are left for a while after use, the silicone rubbers 2a and 2b which are elastic bodies return to the original state.
Further, since the quality of the silicone rubbers 2a and 2b does not change even when they are washed, the silicone rubbers 2a and 2b can be kept clean by washing the bite holding plate after use.

Furthermore, the occlusal correction plate in this embodiment is exposed to saliva because it is used in the oral cavity.
The marker 4 is formed on the surface of the flat plate 3,
Since the marker 4 is protected by a and 2b, the marker 4 does not disappear even if it is repeatedly used by putting it in the oral cavity, and it can withstand long-term use. If various colors are used for the flat plate 3 or a pattern or the like is formed on the flat plate 3, these are made of silicone rubber 2 a, 2 having transparency.
It can be seen from the outside via b, and the appearance is also excellent.

The marker 4 can be formed by providing irregularities on the surface of the plate body 1, for example, the surfaces of the silicon rubbers 2a and 2b, in addition to the lines described in the present embodiment. With such a configuration, by aligning the unevenness with the recess between the teeth located at the midline 6 of each of the upper and lower tooth rows 5a and 5b, the midline can be easily used without using a mirror. 6 can also be combined.

In this embodiment, the plate body 1
Has a configuration in which the flat plate 3 is sandwiched between the silicon rubbers 2a and 2b, but the plate body 1 may be formed of a single material having the same strength and properties as the silicon rubbers 2a and 2b, for example.
