Description

[Detailed Description of the Invention] The present invention relates to a tin cap applied to the treatment of crossbite, and more specifically to a tin cap that causes less discomfort when worn and does not cause inflammation when applied.

BACKGROUND OF THE INVENTION One of the symptoms associated with abnormal bone growth during skeletal formation during human growth is crossbite, particularly mandibular prognathism. In other words, mandibular prognathism is a symptom that occurs when the mandible overgrows with respect to the maxilla of the head, or when the mandible undergrows with respect to the mandible.The treatment for this is as follows: Graber. As supported by the concept of jaw shaping power of TM, it is believed that suppressing the growth of the mandible is effective.

Chin caps are one of the specific orthodontic devices used for this kind of treatment, and the ones currently in practical use are aluminum or plastic ones made by die-casting to match the shape of the human lower jaw. It is a chin cap. When applying it, the patient wears a head cap on the head and places the above-mentioned tin cap on the mandible.The head cap is used as a fixed part, and the head cap and tin cap are attached to a rubber tube with an outer diameter of about 5 mm or
It is connected by a connecting member such as a rubber ring about 10 cm long, and the elastic force of the connecting member strongly presses the chin cap against the mandible, thereby suppressing the growth of the mandible. In this method of treating mandibular prognathism using a chink cap, the fixing part and the part where the pressing force is applied are placed outside the oral cavity, so it does not cause any adverse effects such as movement of the alveolus, and only treats the malformation or functional abnormality of the mandible itself. It is effective in correcting.

By the way, the tin cap used in the above method is formed to fit the shape of the mandible as much as possible so that the patient does not feel any discomfort or discomfort when using it, but the material of the chinch cap is made of aluminum, plastic, etc. Since it is made of a rigid material, it feels like a foreign body when worn, and while the shape of the chin cap is uniform, there are individual differences in the shape of the lower jaw, so it lacks compatibility. This left a feeling of discomfort in the area of the lower jaw where the tin cap came into contact, and long-term use could lead to pain and inflammation. On the other hand, in contrast to the above-mentioned chinch cap, there have also been proposals for chinch caps made of gauze or other material glued to the part of the chink cap that contacts the mandible, but these are still insufficient in terms of compatibility with the mandible. Furthermore, as is common to all of the above, especially with leather tin caps, the lower jaw area that comes into contact with the tin cap often gets stuffy due to moisture emitted from the body, which can lead to discomfort and even inflammation. This is one of the causes.

The present invention was developed with attention to these circumstances, and aims to provide a tin cap for treating mandibular prognathism that causes less discomfort and discomfort when worn, and does not cause inflammation in the area where it is worn. It is something.

The tin cap of the present invention is composed of a flexible sheet material, and includes a holding member having an oval window opening in the center and band parts on both sides, and a holding member attached to the window opening of the holding member. The gist is that it is composed of a cloth or net made of natural or synthetic fibers.

The configuration and effects of the present invention will be explained below based on the drawings, but the following embodiment is only one specific example and is not intended to limit the present invention. All additions are within the technical scope of the present invention.

FIG. 1 is a perspective explanatory view of the tin cap of the present invention, and the tin cap 1 consists of a holding member 2 made of a flexible sheet material and a fabric part 3 made of natural or synthetic fiber. That is, the holding member 2 has band portions 2a on both sides, a band portion 2b that is wider than both side band portions 2a, and an oval window space 2c in the center, and the fabric portion 3 is attached to the oval window space 2c. is provided,
The fabric portion 3 is formed so as to hang down from the oval open window portion 2c. Further, a stopper 7 is fixed to the band portion 2a to engage a rubber ring to be described later.

Next, regarding the material of the tin cap, it is preferable that the flexible sheet is strong enough not to break even when the orthodontic force described below is applied, and the surface that comes into contact with the human body is soft to the touch. Uses synthetic leather seats. Composite materials with cotton cloth attached to the back side are recommended. Further, as mentioned above, all the usual natural or synthetic fibers can be used as the fibers constituting the fabric part, but cotton products are recommended because they feel good against the skin. In addition, as the fibers constituting the fabric part, elastic fibers (for example, 200g/
Fibers that exhibit elastic elongation when stretched with a force of approximately cm ² and do not elongate beyond a certain length (e.g., composite knitted fabrics of rubber and fibers) may be used; in this case, the fabric portion may be suspended from the window opening. The configuration will not allow The same effect can be obtained by attaching a net instead of the fabric.

The method of wearing a chinch cap constructed in this way is almost the same as the conventional method, but to briefly explain it along the lines of Fig. 2, first, the head cap 4 is put on the patient's head, and then as shown in Fig. 1. Apply the shown tin cap 1 to the lower jaw 5. Next, an elastic string such as a rubber ring 6 is prepared, and one end thereof is engaged with the head cap 4 and the other end is engaged with the chin cap 1 to connect the two. In the above, the tip of the lower jaw of the tin cap is inserted into the oval window opening of the tin cap, and the fabric portion of the oval window opening deforms to follow the shape of the lower jaw. In addition, since the chin cap is made of a flexible material, it comes into contact with the lower jaw without any gaps. As a result, the discomfort that the tin cap gives to the mandible (patient) is extremely small, and since the main part of the contact area is made of fabric or mesh, moisture such as sweat is easily dissipated, and the stuffiness phenomenon unlike conventional ones is not observed.

When engaging the tin cap and the rubber ring,
By pulling the tin cap 1 toward the front in the figure and adjusting the length of the rubber ring while checking the tensile force of the rubber ring 6 with a spring balance, the orthodontic force necessary to suppress the growth of the mandible (i.e., the corrective force of the tin cap) can be obtained. Pressing force). If the corrective force is too small, the effect of suppressing the growth of the mandible will be insufficient and no therapeutic effect will be obtained, and if it is too large, it may cause pain or temporomandibular joint disorder. In order to avoid the negative effects of this, the correction force is carefully adjusted.

The basic structure of the present invention is as described above, but in addition to the above, for example, as a method of connecting the head cap and the tin cap, a clasp is attached to the hanging part of the head cap, and the clasp is fixed to the holding member of the chin cap. Examples include a method of connecting the two with a rubber ring or the like. At this time, it is preferable to attach the stopper attached to the head cap to the back of the head, so that the orthodontic force can be applied toward the base of the lower jaw, further enhancing the orthodontic effect.

Since the present invention is structured as outlined above,
The contact area between the lower jaw and the tin cap does not get stuffy due to sweat emitted from the human body, and since the material is flexible, there is little feeling of a foreign body when wearing it, and it can be worn with any shape of the lower jaw. It can be easily adapted to the wearer's clothing and does not shift after wearing. Furthermore, there were no side effects such as inflammation caused by wearing.
