Description

本発明は、マウスピース及びそれを用いた咀嚼筋トレーニング装置に関するものであり、特に咀嚼筋、表情筋および下顎骨周辺筋を含む口腔周辺筋を選択的に強化して筋力バランスを整えるためのマウスピース及びそれを用いたトレーニング装置に関するものである。   The present invention relates to a mouthpiece and a masticatory muscle training apparatus using the mouthpiece, and in particular, a mouse for selectively strengthening muscles around the oral cavity including masticatory muscles, facial muscles, and peripheral muscles of the mandible to adjust muscle strength balance. The present invention relates to a piece and a training apparatus using the same.

頭部の筋は咀嚼筋と表情筋とに大別され、このうち咀嚼筋とは、咀嚼運動に直接関与し歯科領域においては特に重要な筋群であって、咬筋や側頭筋等をいう。また、表情筋とは頭部や顔面部浅層の皮下組織中に存在する口輪筋や頬筋等の薄い筋群をいう。人は加齢が進むことによりこれらの咀嚼筋や表情筋が衰え、また食事の際に左右の歯列の噛む回数に偏りがあることなどから左右の咀嚼筋および表情筋の筋力バランスに偏りが生じることがある。このような筋力バランスの偏りは、顔の表情にも影響し、左右の目の高さに高低差が生じたり、片方の頬や口角が垂れる等の問題が生じてしまう。 The muscles of the head are roughly divided into masticatory muscles and facial muscles. Among them, the masticatory muscles are muscle groups that are directly involved in masticatory movements and are particularly important in the dental field, and include the masseter and temporal muscles. . Facial muscles refer to thin muscle groups such as the muzzle muscles and cheek muscles existing in the subcutaneous tissue of the head and the shallow surface. As people age, their masticatory muscles and facial muscles weaken, and the number of times that the left and right dentitions bite during the meal is biased. May occur. Such a bias in muscular strength also affects facial expressions, causing problems such as a difference in height in the height of the left and right eyes, and a drop on one cheek or mouth corner.

また、下顎骨は左右一対の顎関節をもち、上下、左右、前後の３軸方向に一定の自由な可動性を有している。そして、下顎骨は頭蓋骨から筋肉等によりぶら下がっている構造であり、頭部の重心を調節する重錘、バランサーの役割を果たしている。そのため、下顎骨の偏り（下顎偏位）が起こると、頭位が変化し、頸椎をはじめ脊椎全体に影響が及ぶ。その結果、頸椎の歪み等が生じ、肩凝りや頭痛等の不快症状および身体的苦痛等の不定愁訴を生じる場合がある。 The mandible has a pair of left and right temporomandibular joints and has a certain degree of freedom in the three axial directions of up, down, left, and right. The mandible is a structure that hangs from the skull with muscles, etc., and plays the role of a weight and balancer for adjusting the center of gravity of the head. Therefore, when the mandible bias (mandibular deviation) occurs, the head position changes, and the entire vertebra including the cervical spine is affected. As a result, distortion of the cervical spine and the like may occur, and uncomfortable symptoms such as stiff shoulders and headaches and indefinite complaints such as physical distress may occur.

従来より、口に咥えて上下の歯で繰り返し噛むことにより、咀嚼筋や表情筋を強化する器具が存在する。たとえば、特開２００８−６７７３２号公報にはＵ字型の咬合部を上下歯列間で噛むことにより咀嚼筋が強化され、咬合部を噛んだまま突出部を中心に口をすぼめて閉じることにより表情筋のひとつである口輪筋が強化される口腔筋トレーニング器具が開示されている（特許文献１）。 Conventionally, there are devices that reinforce the masticatory muscles and facial muscles by repeatedly biting with the upper and lower teeth in the mouth. For example, in Japanese Patent Application Laid-Open No. 2008-67732, a masticatory muscle is strengthened by biting a U-shaped occlusal portion between upper and lower dentitions, and by closing the mouth with its mouth centered around the protruding portion while biting the occlusal portion. An oral muscle training device in which the muzzle muscle, which is one of the facial muscles, is strengthened is disclosed (Patent Document 1).

また、特開２０１２−４５１４３号公報には、咀嚼筋、表情筋および下顎骨周辺筋を含む口腔周辺筋を強化するためのマウスピースが開示されている（特許文献２）。 Japanese Patent Laid-Open No. 2012-45143 discloses a mouthpiece for strengthening peripheral muscles of the oral cavity including masticatory muscles, facial muscles, and peripheral muscles of the mandible (Patent Document 2).

特開２００８−６７７３２号公報JP 2008-67732 A 特開２０１２−４５１４３号公報JP 2012-45143 A

しかしながら、特許文献１に記載された発明においては、咬合部が人間の歯列に沿ったＵ字型に一体的に形成されているため、上下歯列間で咬合部を全体的に噛みこむことで咀嚼筋を全体的に強化することはできるが、たとえば咀嚼筋および表情筋の左右の筋力バランスが偏っているような場合に、左右いずれかの咀嚼筋および表情筋を選択的に強化して調整したり、噛み合わせを矯正することはできなかった。 However, in the invention described in Patent Document 1, since the occlusal portion is integrally formed in a U shape along the human dentition, the entire occlusal portion is bitten between the upper and lower dentitions. The masticatory muscles can be strengthened as a whole, but for example, if the left and right muscle strength balance between the masticatory and facial muscles is biased, It was not possible to adjust or correct the bite.

また、ユーザの噛み合わせの悪さにより咬合面が平らでないような場合には、歯列全体で咬合部を噛みこんでも、咬合平面に対して高い部位は咬合圧が高くなるのに対し、低い部位は咬合圧が弱くなり、却って咬合面の高低差に依存して咀嚼筋および表情筋が偏って強化されてしまうという問題があった。 In addition, when the occlusal surface is not flat due to the poor bite of the user, even if the occlusal portion is bitten in the entire dentition, the occlusal pressure is higher in the higher part than the occlusal plane, whereas the lower part However, there was a problem that the bite pressure was weakened and the masticatory and facial muscles were biased and strengthened depending on the height difference of the occlusal surface.

一方、特許文献２に記載の発明によれば、咀嚼筋、表情筋および下顎骨周辺筋を含む口腔周辺筋を選択的に強化して筋力バランスを整えるためのマウスピースが記載されているが、トレーニングの効果に対するフィードバック情報が得られないという問題があった。 On the other hand, according to the invention described in Patent Document 2, a mouthpiece for selectively strengthening peripheral muscles of the oral cavity including masticatory muscles, facial muscles and peripheral muscles of the mandible is described, There was a problem that feedback information about the effect of training could not be obtained.

本発明は、このような問題点を解決するためになされたものであって、咀嚼力が低下した高齢者に対して、特に、咀嚼筋、表情筋および下顎骨周辺筋を含む口腔周辺筋を選択的に強化して筋力バランスを整えるためのマウスピースを提供し、トレーニングの効果に対するフィードバック情報が得られるトレーニング装置を提供することを目的としている。 The present invention has been made in order to solve such problems, and particularly for elderly people with reduced masticatory powers, particularly perioral muscles including masticatory muscles, facial muscles and peripheral muscles of the mandible. It is an object of the present invention to provide a mouthpiece for selectively strengthening and adjusting the strength balance, and to provide a training apparatus that can obtain feedback information on the effect of training.

以下に、トレーニング装置１００の種々のトレーニング機能を、圧力センサ１０ａ１〜１０ｆ２として、感圧導電ゴムを用いた例について説明する。
電源スイッチ(不図示)をＯＮし、入力部２４で、年齢，義歯数を入力すると、５０歳以上の場合、
目標回数／日＝１８００×｛１００％−(年齢−５０)×０．７７％−(義歯数)×２％｝
が演算、設定される。
また、５０歳未満の場合、ディフォルト値として、目標回数／日として、２７００回／日が設定される。この値は、入力部２４で設定変更可能となっている。 Below, the various training functions of the training apparatus 100 are demonstrated about the example using pressure-sensitive conductive rubber as the pressure sensors 10a1-10f2.
When the power switch (not shown) is turned on and the age and the number of dentures are input at the input unit 24,
Target frequency / day = 1800 × {100% − (age−50) × 0.77% − (number of dentures) × 2%}
Is calculated and set.
Further, in the case of younger than 50 years old, 2700 times / day is set as the default number of times / day. This value can be changed by the input unit 24.

マウスピース１を形成する上歯用バイトパッド１ａ，下歯用バイトパッド１ｂを装着し、咀嚼を開始する。
咀嚼の回数、咀嚼圧は、圧力センサ１０ａ１〜１０ｆ２で咀嚼する毎に測定される。圧力センサ１０ａ１〜１０ｆ２の測定で得られた咀嚼圧は、読み取り部２３で、例えば、読み取り信号として、１３．５６ＭＨｚの電磁波により、外部通信部１３を介して、時分割でほぼリアルタイムで読み取られる。
読み取られた咀嚼の回数、咀嚼圧は、トレーニング装置１００に記憶され、圧力の強さに応じて色別に例えば６段階に、それぞれの圧力センサ１０ａ１〜１０ｆ１に対応して表示部２２に表示される。
また、残りの咀嚼回数も併合せて、表示部２２に表示される。
咀嚼回数の目標が達成されると、その旨の表示が表示部２２に表示される。 The upper tooth bite pad 1a and the lower tooth bite pad 1b forming the mouthpiece 1 are attached, and chewing is started.
The number of chewing times and the mastication pressure are measured every time the pressure sensors 10a1 to 10f2 chew. The mastication pressure obtained by the measurement of the pressure sensors 10a1 to 10f2 is read by the reading unit 23, for example, as a read signal by an electromagnetic wave of 13.56 MHz through the external communication unit 13 in almost real time.
The read number of mastications and mastication pressure are stored in the training device 100 and displayed on the display unit 22 corresponding to each of the pressure sensors 10a1 to 10f1, for example, in six levels according to the strength of the pressure. .

外出等でトレーニング装置１００から離れることで、読み取り部２３から１３．５６ＭＨｚの電磁波が所定秒、外部通信部１３で受信できない場合は、圧力センサ１０ａ１〜１０ｆ２で得られた咀嚼回数，咀嚼圧を圧力検出部１０の記憶部に記憶し、再度、読み取り部２３による読み取りが再開されると、一旦記憶された咀嚼回数，咀嚼圧を外部通信部１３から送信する。 If the 13.56 MHz electromagnetic wave cannot be received from the reading unit 23 by the external communication unit 13 by leaving the training device 100 by going out or the like, the mastication frequency and mastication pressure obtained by the pressure sensors 10a1 to 10f2 are used as pressure. When it is stored in the storage unit of the detection unit 10 and reading by the reading unit 23 is resumed, the number of mastication times and the mastication pressure once stored are transmitted from the external communication unit 13.
