Description

{Mouse piece for correcting a temporomandibular joint}

In general, the jaw joint of a person is a joint which is the central axis of the opening motion of the mouth, and is a bilateral joint performing the function of mastication of food and voice.

These jaw joints consist of the temporal bone and the mandible, and nine of the twelve cranial nerves pass through the jaw joint and are an important part of the distribution of blood vessels, lymph nodes and nerves.

Therefore, when the jaw joint performing the important role as described above becomes unbalanced, the spinal joint and musculoskeletal diseases such as the central nervous system occur due to the failure to maintain the balance of the muscles associated with the jaw joint.

Such diseases caused by jaw joint imbalance can occur throughout the body, such as headache, dizziness, circulatory diseases, otorhinolaryngological diseases, genitourinary diseases, respiratory diseases, and growth disorders.

Therefore, a jaw joint protecting apparatus such as a pad for jaw joint correction, a mouthpiece, and the like is used for treating a disease caused by a jaw joint imbalance.

As a device for treating a jaw joint imbalance in the past, the oral appliance of U.S. Patent No. 5,259,762 and the appliance of the oral appliance of U.S. Patent No. 5,624,257 are known.

These prior art techniques have a disadvantage in that it is structurally impossible to solve the jaw joint imbalance which is generated differently for each individual because of the technique in which the body part where the tooth is seated is integrally formed or is designed to have a fixed height, .

As another conventional technique, Korean Patent No. 10-926483 discloses a technique of a jaw joint balancing device, but it is a technology that may cause the same problems as the known technologies of the above-mentioned United States patent.

The present invention has been made in order to solve the problems of the related art as described above, and it is an object of the present invention to provide a mouthpiece for a jaw joint orthodontic which is easy to apply to various types of jaw joints having different shapes, The present invention has the technical problem.

According to an aspect of the present invention, there is provided a mouthpiece for a jaw joint orthodontic treatment comprising: a receiving portion for receiving upper and lower teeth in the oral cavity; A front guide portion formed of a protruded rim surface and a rear guide portion formed of a rim surface protruding upward and downward along a rear surface and a side surface of the rear portion of the receiving portion, And the portion is made of a thermoplastic material.

The dental mouthpiece for orthodontic treatment according to the present invention having the above-described structure is made of a thermoplastic material, so that heat is applied to the dental mouthpiece to dissolve each part of the dental mouthpiece to fit the shape of the wearer's teeth due to thermal deformation The mouthpiece is best fitted to the patient's jaw so that the shape of the oral cavity in the oral cavity is different from that of the individual patient and the jaw of the patient is maintained in the ideal position for the individual, Thereby providing an optimal comfort feeling to the patient.

In addition, the conventional mouthpiece is inconvenient and insufficient for balancing the jaw joint. However, the mouthpiece of the present invention is a very advanced invention having an advantage that it is very comfortable and unnecessary force is not applied to the teeth.

In addition, unless otherwise defined, the terms used in the description of the present invention have the same meaning as commonly understood by one of ordinary skill in the art to which the present invention belongs. In the following description and the accompanying drawings, A detailed description of known functions and configurations that may be unnecessarily blurred is omitted.

FIG. 1 is a perspective view of a mouthpiece for jaw joint correction according to the present invention, FIG. 2 is a sectional view taken along line A-A 'of FIG. 1, FIG. 3 is a front view of a mouthpiece for jaw joint correction of the present invention, A top view and a bottom view of the mouthpiece.

Referring to the drawings, the dental mouthpiece 1 of the present invention is generally similar in shape to a conventional dental mouthpiece. That is, it has a U-shaped body so that the upper and lower teeth can be inserted into the oral cavity.

More specifically, the mouthpiece (1) of the present invention comprises a receiving portion (10) in which the upper and lower teeth in the oral cavity are fixed, and an upper portion and a lower portion located along the front side and the side surface of the receiving portion And a rear guide portion 30 having a front surface guide portion 20 having a protruding rim surface and a rim surface protruding upwardly and downwardly along a rear surface and a side surface of the rear side of the receiving portion 10 .

The receiving portion 10 is configured to include an upper receiving surface 11 on which an upper tooth in the oral cavity is placed and a lower receiving surface 12 on which the lower oral tooth is mounted. Therefore, the bottom surface of the upper tooth is brought into contact with the upper bearing surface 11, and the upper surface of the lower tooth comes into contact with the lower bearing surface 12.

The front guide portion 20 is composed of an upper front guide 21 protruding upward from the front side of the receiving portion 10 and a lower front guide 22 protruding downward from the front side of the receiving portion 10 .

Here, the height of the upper and lower front guides 21 and 22 is preferably less than the height of the average tooth, in order to minimize the inconvenience of the patient.

The rear guide portion 30 includes an upper rear guide 31 protruding upward from the rear side of the receiving portion 10 and a lower rear guide 32 protruding downward from the rear side of the receiving portion 10.

The upper guide 31 is a lingual side of the upper teeth, and the upper guide 31 is a lingual side of the lower teeth. The rear guide 32 is the lingual side of the mandibular teeth.

3, the upper front guide 21 of the present invention is formed with a lap 23 at its center, and the lap 23 penetrates the upper front guide 21 Thereby giving comfort to the mouthpiece user of the present invention. Therefore, the mouthpiece of the present invention is formed such that the height h2 of the upper rear guide 31 is higher than the height h1 of the upper side guide 21.

The receiving portion 10 of the present invention is formed such that the thickness a1 of the side surface (posterior portion) is thicker than the thickness a2 of the front surface (anterior portion) To be customized to the dentition. In the embodiment of the present invention, the thickness a2 of the front surface is 3 mm and the thickness a1 of the side surface is 5 mm.

The thickness b of the front guide portion 20 of the embodiment of the present invention is 3 mm and the thickness c of the rear guide portion 30 is 2 mm.

In addition, the receiving portion width d1 on both sides of the receiving portion 10 of the embodiment of the present invention is formed wider than the receiving portion width d2 in the center of the bottom portion. This is to give comfort to the teeth and to have a margin for correction.

The total length L of the dental mouthpiece according to the present invention is about 58 mm, but it can be used by adjusting the entire length by cutting the rear side of the dental mouthpiece according to the length of the teeth row of the patient.

The mouthpiece of the present invention is made of a thermoplastic material. This is because the shape of the oral cavity in the oral cavity is different for each individual patient, so that the patient's jaw is maintained as an ideal position for the individual, and further, the tooth is prevented from flowing so as to give an optimal comfort to the patient .

That is, the mouthpiece according to the present invention is worn by the guide of the present invention so as to be held against the upper teeth when the mouthpiece is inserted into the mandible. In the procedure of the first mouthpiece, 10, the front guide portion 20 and the rear guide portion 30, the respective portions of the receiving portion 10, the front guide portion 20 and the rear guide portion 30 are thermally deformed The mouthpiece is best fitted to the patient's jaw since it is melted to fit the shape of the wearer's teeth.

In the embodiment of the present invention, a material called EVA (Ethylene Vinyl Acetate) was used as the thermoplastic material. The EVA material is melted in water at about 80 degrees Celsius and is adjusted to the shape of the wearer's teeth by the lips in the mouth.

On the other hand, the mouthpiece of the present invention has a transparent hue, thereby minimizing visual rejection on appearance.
