Description

本発明は、咬合診断装置、特に、東洋医学における経穴（いわゆるツボ）の電位の変化から、咬合、いわゆる歯の噛み合わせの正常・異常を診断する装置に関する。さらには、咬合を変化させたときの左右経穴の電位差、有意差、顎関節位置などのデータを測定する方法に関する。  The present invention relates to an occlusion diagnostic apparatus, and more particularly to an apparatus for diagnosing normality / abnormality of occlusion, so-called tooth meshing, from changes in the potential of acupuncture points (so-called acupoints) in Oriental medicine. Furthermore, the present invention relates to a method for measuring data such as a potential difference between the left and right acupuncture points, a significant difference, and a temporomandibular joint position when the occlusion is changed.

咬合異常が、心臓病，頭痛，不定愁訴，胃腸病等、多くの病気の遠因になることが知られてきている。咬合を正常に治療することは歯科治療で行われているが、現在まで、歯科治療で咬合が正常であるかどうかの基準がなく、歯科治療によって咬合が正常になったかどうかを判定することが困難であった。
一般に、咬合のチェックは、フィットチェッカや咬合紙を用いて行われているが、判定は歯科医の経験に基づいて行われており、判定にバラツキがあった。
したがって、咬合の正常・異常を診断できる診断装置の開発が要求されている。Occlusal abnormalities are known to cause many diseases such as heart disease, headache, indefinite complaints, and gastrointestinal diseases. Normal treatment of occlusion is performed in dental treatment, but until now there is no standard for whether occlusion is normal in dental treatment, and it is possible to determine whether occlusion has become normal by dental treatment It was difficult.
In general, the occlusion check is performed using a fit checker or occlusion paper, but the determination is based on the experience of a dentist, and the determination varies.
Therefore, there is a demand for development of a diagnostic apparatus that can diagnose occlusion normality / abnormality.

本発明の目的は、咬合の正常・異常を診断できる咬合診断装置を提供することにある。
本発明の他の目的は、このような咬合診断装置において、咬合データを測定する方法を提供することにある。
本発明のさらに他の目的は、咬合の正常・異常を診断できる咬合診断方法を提供することにある。
本出願の発明者は、特定の経穴（井穴および聴宮）における電位の変化により咬合の正常・異常を診断できることを見い出し、咬合が正常か異常かを診断する診断装置および方法と、咬合データ測定方法を開発した。
耳の近くに存在する経穴である左右の聴宮、手足の指に存在する経穴である左右の井穴に電極を取り付け、咬合診断装置により左右電極の電位差を測定する。顎運動による運動エネルギーは電気量に変換され、顎関節，下顎，上顎に、それぞれ電位として現れる。顎関節，上顎，下顎を、前後，左右，上下に動かして、咬合に異常がなければ、前後，左右，上下の各運動における各測定点の左右電極の電位差は０に近い。もし何れかに異常があれば、咬合異常のある部位の電位変化が経絡を通じて、測定点である井穴および聴宮に興奮を生ぜしめ、電位差に負あるいは正の変化を示す。それによって、咬合異常がどこにあるかを診断することができる。The objective of this invention is providing the occlusion diagnostic apparatus which can diagnose normality / abnormality of occlusion.
Another object of the present invention is to provide a method for measuring occlusion data in such an occlusal diagnosis apparatus.
Still another object of the present invention is to provide an occlusal diagnosis method capable of diagnosing occlusion normality / abnormality.
The inventor of the present application finds that occlusion normality / abnormality can be diagnosed by changing potentials at specific acupuncture points (wellholes and auditoriums), and diagnostic device and method for diagnosing whether occlusion is normal or abnormal, and occlusal data measurement Developed a method.
Electrodes are attached to the left and right auditoriums, which are the acupuncture points near the ears, and the left and right wells, which are the acupuncture points present on the toes and fingers. Kinetic energy generated by jaw movement is converted into electricity, and appears as electric potentials in the temporomandibular joint, lower jaw, and upper jaw. If the temporomandibular joint, upper jaw, and lower jaw are moved back and forth, left and right, up and down, and there is no abnormality in occlusion, the potential difference between the left and right electrodes at each measurement point in front and back, left and right, and up and down movements is close to zero. If there is any abnormality, the potential change at the site with the occlusal abnormality causes excitement in the wells and the auditorium through the meridians and shows a negative or positive change in the potential difference. Thereby, it is possible to diagnose where the occlusal abnormality is.

まず、電位差を測定する測定点について説明する。
（１）左右聴宮の２点である。聴宮は、図１に示すように、顎関節の真上の皮膚上にあり、顎関節の正常・異常を、診断する測定点である。
（２）左右胃経（胃経井穴）の２点および左右大腸経（大腸経井穴）の２点である。胃経は、足第２指の爪の根元にある井穴であり、大腸経は、手第２指の爪の根元にある井穴である。図２Ａ，図２Ｂに、これら胃経井穴および大腸経井穴の位置を示す。
上顎と胃経、下顎と大腸経の間には密接な関係のあることが、多くの実験で確かめられている（本山博、尾澤文貞による協同研究『ＡＭＩによる神経と経絡の研究』第ＩＶ章「咬合治療の効果」１３１頁〜１４３頁［宗教心理出版１９８７］）。なお、大腸経，胃経は、「歯脈」とも呼ばれている。
下顎の咬合変化は、大腸経井穴にＢＰ電流値の変化として現れ、上顎の咬合変化は、胃経井穴にＢＰ電流値の変化として現れることが知られている。図３および図４は、ＡＭＩ（経絡−臓器機能測定器）で胃経井穴，大腸経井穴に電極を置き、咬合を変化させて、各井穴におけるＢＰ電流値の変化を調べたデータである。なお、ＢＰ電流値は、皮膚刺激に対して表皮基底膜で分極が生じる前に真皮内を流れる電流の値であり、経絡機能のパラメータである。
図３および図４において、系列１は右胃経のＢＰ値を、系列２は左胃経のＢＰ値を、系列３は右大腸経のＢＰ値を、系列４は左大腸経のＢＰ値をそれぞれ示している。
図３のデータは、歯の噛み合わせ位置を前後に変化させた場合のデータ、図４は噛み合わせた状態で、下顎を前後にずらした場合のデータを示している。図３および図４に示した、咬合変化による大腸経，胃経でのＢＰ変化は、＋側（ＢＰ増加）、−側（ＢＰ減少）の両方向の変化を、咬合の違いで示している。
本願発明者は、さらに聴宮（顎関節に対応），大腸経井穴（下顎に対応），胃経井穴（上顎に対応）での変化は、神経性のものか、経絡性のものかを確かめる実験を行った。
咬合変化による刺激が、顎関節の真上の皮膚上にある聴宮の電位、手第２指の爪の根元にある大腸経井穴の電位、足第２指の根元にある胃経井穴の電位が、＋側あるいは−側の方向の変化を示すかどうかを調べ、それは神経系情報伝達による変化であるか、あるいは経絡系情報伝達による変化であるかを、１１人の被験者Ａ〜Ｋについて以下の方法で調べた。
この方法には、本発明の咬合診断装置を用いた。図５には、咬合診断装置の基本的構成をブロック図で示す。この咬合診断装置は、基本的には、電位差計８と演算装置２０とから構成される。
電位差計８は、高インピーダンスアンプ１０，差動アンプ１２，絶縁アンプ１４，ローパスフィルタ１６，Ａ／Ｄコンバータ１８から構成される。また、演算装置２０は、パーソナルコンピュータ（ＰＣ）により構成される。
高インピーダンスアンプ１０には、＋側電極２と−側電極４とからなる複数組の測定電極と、１個のアース電極６とが、各リード線を経て、接続されている。
図６は、電位差計８の回路図を示す。なお、図６では、図面を簡単にするため、１組の測定電極２，４に対する回路のみを示している。高インピーダンスアンプ１０は、２個のアンプ１０Ａ，１０Ｂを有している。＋側電極２で検出された電位は、アンプ１０Ａを経て、差動アンプ１２の＋側入力端子に接続され、−側電極４で検出された電位は、アンプ１０Ｂを経て、差動アンプ１２の−側入力端子に接続されている。
差動アンプ１２は、これら２つの入力の差をとり、差出力を絶縁アンプ１４に入力する。絶縁アンプ１４は、発光素子１４Ａ，受光素子１４Ｂを有し、差動アンプ１２の差出力を光信号に一旦変換し、再び電気信号に戻して出力する。ローパスフィルタ１６では、高周波ノイズを除去して、ＡＤコンバータ１８に入力する。ＡＤコンバータは、ローパスフィルタ１６からのアナログ信号をデジタル信号に変換し、パーソナルコンピュータ２０に入力する。
なお、以上のような構成の電位差計８は、既存のものを用いることができる。
上述の咬合診断装置を用いて測定する前に、電位差計を０点調節する。０点調節は、＋側電極２と−側電極４とを接触させて、電位差出力を０にすることにより行う。
次に、２つの電極のうち、−側電極４をアースにショートして、＋側電極２のみを左聴宮，左胃経井穴，左大腸系井穴に貼付して、下顎を噛みしめる，開ける，左，右，前，後に動かして咬合を変化させ、その咬合変化による刺激が上記の３測定点で、負または正、あるいは正，負の両方の電位変化を生ぜしめるか、生ぜしめないかを調べた。
もし神経反応であれば、神経興奮による電位変化は常に負電位変化であるから、３測定点で全て負電位変化として現れるはずである。経絡性変化であれば、負あるいは正の電位変化として現れる。経絡反応の特徴は、神経の反応のように、刺激を感じなければ全く反応が出ないのとは違って、刺激が弱く感じられなくても、或る微弱な刺激、例えば咬合変化のような、何の痛みも感じない刺激であっても、反応を示すことである。
１１人の被験者に咬合変化テストをして得た各測定点での正電位変化（＋），負電位変化（−）の度数を表１に示す。１人の被験者で、各測定点で＋変化，−変化，両方を示したものはその両方を度数に加えた。

Figure 2005025444
表２は、各被験者Ａ〜Ｋの電位変化の様子を示す。
Figure 2005025444
上記１１人の被験者の、前後，左右，上下への下顎のずれによる咬合変化刺激に対しての聴宮（顎関節），胃経井穴（上顎），大腸経井穴（下顎）での＋あるいは−の電位変化を表にしたのが表３である。
Figure 2005025444
これをｍ×ｎの分割表でχ２テストしても、表４に見られるように、＋変化度数と−変化度数がほぼ同じであり、＋変化，−変化，無変化の間に有意差が見られない。これは、咬合変化刺激によって生じる変化は、常に−電位変化を示す神経性反応による変化ではないことを示す。
Figure 2005025444
また、各人のデータを通じて、咬合変化をするたびに顎関節測定点（聴宮），上顎測定点（胃経井穴），下顎測定点（大腸経井穴）で、＋変化あるいは−変化がみられる。このことは、上顎，下顎での咬合変化が神経系とは異なる経絡を通して、聴宮，胃経井穴，大腸経井穴で数秒の間に電位変化を生ぜしめることを示している。その理由は、上顎，下顎，顎関節は神経的には三叉神経の支配領域であり、大腸経井穴，胃経井穴は三叉神経分布とは直接関係がないからであり、経絡的には上顎は胃経、下顎は大腸経の支配を受ける。また、聴宮での電位変化も＋，−の変化がみられるから、これも神経性のものではなく、経絡系変化と考えられる。
図７は、被験者Ｂの咬合診断装置の出力波形を示す。この被験者の場合、上顎犬歯で差し歯になっているが、そのために上顎に異常が考えられるが、咬合変化（噛みしめる→口をあける→下顎を左にずらす→下顎を右にずらす→下顎を前にずらす→下顎を後にずらす）によって、上顎咬合に関係する胃経では大きな正電位変化が見られる。聴宮では、噛みしめた後、最後まで−０．００２Ｖの負電位変化が見られる。
図８は、被験者Ｇの咬合診断装置の出力波形を示す。この被験者の場合、咬合変化のたびに大腸経で顕著な正電位変化がみられる。聴宮では、後ろへずらすと−０．０２Ｖで、負電位変化が生じている。
図９Ａ，図９Ｂは、被験者Ｇの咬合診断装置の出力に基づいて、有意差をみるためのｔ−検定を行った結果を示す。このｔ−検定は、パーソナルコンピュータ２０により行われる。図９Ａは、噛みしめたときのｔ−検定の結果を、図９Ｂは、下顎を後ろにずらしたときのｔ−検定の結果を示す。
図１０は、被験者Ａの咬合診断装置の出力を示す。この被験者では、咬合変化に対して正，負電位変化があまり見られないが、顎関節，上顎，下顎共に咬合変化に対して僅かの正あるいは負の電位変化、０．００１Ｖ以下あるいは無変化を示している。
以上のようにして、聴宮，胃経，大腸経の測定点における電位変化が経絡系によるものであることが確かめられた。
次に、本発明の実施例について詳細に説明する。本発明の咬合診断装置は、図５および図６に示したものである。以下に説明する咬合診断および咬合データ測定方法については、この咬合診断装置を利用して行う。
まず、電位差計において、０点調節をする。０点調節は、＋側電極２と−側電極４とを接触させて、電位差出力を０にすることにより行う。
次に、各＋側電極２を、左聴宮，左大腸経井穴，左胃経井穴に付ける。各−側電極４を、右聴宮，右大腸経井穴，右胃経井穴に付ける。アース電極６を、手首に取り付ける。そして、左右聴宮の電位差，左右大腸経井穴の電位差，左右胃経井穴の電位差を同時に測定する。この場合、０．１秒単位で連続測定し、１秒単位で測定値をコンピュータ２０に取り入れる。
電位差計８では、＋側電極２と−側電極４が検出した測定点の電位を、高インピーダンスアンプ１０で増幅した後、差動アンプ１２で電位差をとる。電位差は、絶縁アンプ１４を経て、ローパスフィルタ１６に送られ、高周波成分を除去した後、Ａ／Ｄコンバータ１８でアナログ信号をデジタル信号に変換し、パーソナルコンピュータ２０に供給する。
測定は、次のような順序で行う。（１）安静状態（３０秒間）、（２）噛みしめる（３０秒）、（３）安静状態（３０秒）、（４）口を開ける（３０秒）、（５）安静状態（３０秒）、（６）下顎を左にずらす（３０秒）、（７）安静状態（３０秒）、（８）下顎を右にずらす（３０秒）、（９）安静状態（３０秒）、（１０）下顎を前にずらす（３０秒）、（１１）安静状態（３０秒）、（１２）下顎を後ろにずらす（３０秒）。
連続データはパーソナルコンピュータ２０にインストールしたプログラムに従って、波形グラフとして取り出される。また、１秒毎の測定値（電位差）は、安静状態時の測定値と、咬合変化時の測定値とを、パーソナルコンピュータにインストールしたプログラムに従ってｔ−検定（有意差を見る）をし、表（後述する図１５に示すような）として出力する。
以上のようにして取り出された波形グラフおよび／またはｔ−検定表に基づいて、咬合の正常・異常の診断は、パーソナルコンピュータにインストールしたプログラムにより行われる。
このようなプログラムにおける咬合診断の基準は、次のとおりである。
１）初めの安静状態時の左右電極間の電位差が±０．０５Ｖ（５０ｍＶ）の範囲外であれば、筋肉の緊張，咬合の異常とみなし、範囲内であれば正常とみなす。
２）噛みしめる、口を開ける、下顎を前・後・左・右にずらす等の咬合変化時に、聴宮，胃経井穴，大腸経井穴の何れかで、それぞれの安静状態時の電位差と咬合変化時の電位差との間に有意差（ｔ−検定）がみられると、咬合異常と判定する。
３）咬合に異常がなければ、咬合変化によって大きな変化はみられず、波形グラフの基線は０Ｖに近いところにある。
以上のような診断基準に基づくプログラムによる診断方法を説明する。
１）安静状態時の顎関節、上顎，下顎の咬合の正常・異常の判定
顎関節、上顎、下顎の左右電極間の電位差が±０．０５Ｖ（５０ｍＶ）の範囲内であれば正常と判定する。範囲外ならば、咬合異常と判定する。
２）咬合変化時の判定
噛みしめる、口を大きく開ける、下顎を左あるいは右にずらす、前あるいは後にずらす等、咬合を変化させることによって、左右聴宮，左右胃経井穴，左右大腸経井穴間の何れかで電位差が−側あるいは＋側に変化して、ｔ−検定による有意差が見られる場合、聴宮ならば顎関節に異常、胃経井穴ならば上顎に咬合異常、大腸経井穴ならば下顎に咬合異常があると判定する。
総合的判定としては、３つの測定点で上下・前後・左右に咬合を変化させて、胃経井穴で最大，最多の電位差変化が生じれば、上顎で咬合異常が最大であると判定する。大腸経井穴，聴宮についても同様に判定する。
但し、聴宮の場合は、経絡反応による電位差変化のみでなく、顎関節に異常があり、その顎関節周囲の筋肉に緊張がある場合は、咬合変化でその筋肉に−電位が生じると予想される。
次に、各被験者のデータを示して、診断の実例を示す。
図１１，図１２は、被験者Ｉの電位差の出力波形を示す図である。図１１を見ると、初めの安静状態時に大腸経井穴で＋０．０５Ｖ（＋５０ｍＶ）以上である。図１２を見ると、やはり初めの安静状態時に聴宮で−０．５６Ｖと、大きく−側にずれている。以上のことは、この被験者は、下顎と顎関節に異常があると考えられる。下顎を前にずらすと、聴宮で０．０２Ｖ大きく＋側に変化する。この場合は、右顎関節周囲の筋肉に緊張が生じ−電位が生じ、電位差は＋側に変化したものであるから、右顎関節に異常ありと判定する。なお、この電位差計では、左側電極が＋側電極、右側電極が−側電極であるから、左側電極に−電位変化が生じれば電位差は−側に変化し、右側電極に−電位変化を生じれば電位差は＋側に変化する。
図１３は、被験者Ｋの電位差の出力波形を示す図である。この被験者は、右下奥歯を抜歯しており、咬合は正常でなかった。最初の安静状態から噛みしめる，口を開けるまでは変化がないが、下顎を左右，前後にずらすと、顎関節，上顎，下顎共に著しく（約０．０２Ｖ〜０．０２５Ｖ以上）＋側に電位差変化が生じている。これは咬合全体が異常であることを示す。聴宮の＋側への電位差変化から、右顎関節に異常が考えられる。
図１４Ａ，図１４Ｂ，図１４Ｃは、この被験者Ｋのｔ−検定の結果を示すデータである。図１４Ａは聴宮に対するデータを、図１４Ｂは胃経井穴に対するデータを、図１４Ｃは大腸経井穴に対するデータを、それぞれ示す。
図１５は、被験者Ｌ（表２には記載されていない）の出力波形を示す図である。この被験者は、両側の親知らずを抜歯済みであった。安静状態，咬合変化の全てで＋，−の変化は基線０Ｖを中心に±０．０２Ｖにあり、全体として咬合には異常がないことがわかる。
図１６，図１７は、被験者Ｈの出力波形を示す図である。図１６を見ると、聴宮の出力は−０．０２５Ｖで、咬合変化によってもあまり変化を示さない。大腸経井穴（下顎）の出力も咬合変化による変化は少ないが、基線が−０．１８Ｖ近辺にあり、図１７を見ると、胃経胃穴（上顎）は基線＋０．３５Ｖ近辺にある。
総合判定としては、上顎，下顎共に咬合にずれがあるが、それが長年の習慣となって、顎関節には咬合異常がそれほどには見られないと思われる。
以上は、電位差計の出力データおよび／またはｔ−検定による咬合の正常・異常の診断であった。
次に、特殊なケースとして、スプリント（ｓｐｒｉｎｔ）を装着する被験者の出力波形をとり、波形の変化を検討した結果について説明する。
まず、歯のないスプリントを装着し、波形をとった。図１８に、その波形を示す。咬合変化をする前の波形を見ると、顎関節の状態を示す聴宮では電位差は−である。これは左顎関節の筋肉に緊張があることを示す。
被験者から歯のないスプリントを装着し噛みしめてフィットチェッカを採取した。図１９に、そのフィットチェッカの写真を示す。フィットチェッカでは、左顎関節が低く、左顎関節に緊張があると思われる。波形による検討に一致することがわかる。
次に、顎を大きく開ける，閉じるの咬合変化に対する反応で見ると、口を開けると左右の顎関節に緊張が生じた。これは咬合全体が低くて、常に噛みしめているのに慣れているので、口を開けると緊張が生じたと考えられる。次に、下顎を右にずらすと右顎関節に緊張が生じた。これは下顎が常に左にずれているために、右にずらすと右顎関節に緊張が生じたと考えられる。
以上の結果から、咬合が全体に低く、左顎関節が右顎関節より低く、下顎が左にずれている。そのために、咬合変化前に左顎関節に緊張があり、下顎が左にずれているために、口を開けても、右にずらしても、右顎関節に緊張が生じやすいと思われる。
下顎のパラメータである大腸経井穴の電位差も、上顎のパラメータである胃経井穴の電位差も正である。
次に、歯のついているスプリントを装着し、波形をとった。図２０に、その波形を示す。
被験者から歯のついているスプリントを装着し噛みしめてフィットチェッカを採取した。図２１に、そのフィットチェッカの写真を示す。左側には穴が開いているが、右側には穴が開いていないから、右顎関節が低いことがわかる。
図２０の波形をみると、歯のないスプリントを装着したときの図１８の波形とは逆に、咬合変化前のデータは聴宮での電位差は正（２〜３ｍＶ）を示す。これは右顎関節に少し緊張があったことを示す。フィットチェッカのデータと一致する。口を開けると、僅かに１ｍＶ低下した。その他の咬合変化ではほとんど反応がみられない。従って、咬合はおおよそ正常であると考えられる。
次に、顎関節の３次元解析と診断について説明する。ある被験者の左聴宮に＋側電極２を、右聴宮に−側電極４を取り付ける。下顎を上下，左右，前後に動かして、顎関節の動きをＸＹＺの３次元座標で解析する。左右方向をＸ軸、上下方向をＹ軸、前後方向をＺ軸とする。顎関節とそれを動かす周囲の筋肉の状況は、聴宮で見られる。なお、このような座標解析は、パーソナルコンピュータ２０にインストールされたプログラムにより実現される。
以下、一例の咬合変化に対応して説明する。
（１）噛みしめる
左顎関節で緊張が生じた。これは、左顎関節が常時開く方向にあり、噛みしめる方向で緊張が生じるからである。緊張すると、−電位が生じる。左顎関節で負となれば両電極間の電位差は負−Ａ（ｃｌ）、右顎関節で負となれば両電極間の電位差は正＋Ａ（ｃｌ）となる。
この、負，正の電位差変化値をＹ軸にとる。図２２は、その電位変化値をＹ軸に示した３次元座標を表す。
（２）口を大きく開ける
左右の何れかの顎関節とその周囲の筋肉に緊張が生じる。これは顎関節が常時、閉まる方向に慣れているのが、開けたので緊張が生じたからである。
左顎関節緊張の場合は、左顎関節が常時閉まる方向にあったのが、開けたので左顎関節に緊張が生じた。電位差は負−Ｂ（０）となる。右顎関節緊張の場合は、右顎関節が常時閉まる方向にあったのが、開けたので右顎関節に緊張が生じ、電位差は正＋Ｂ（０）となる。この電位差変化値をＹ軸にとる。図２３は、その電位差変化値をＹ軸に示した３次元座標を表す。
（３）下顎を左にずらす
左顎関節に緊張が生じた場合、左顎関節が右に常時ずれていたのが、下顎を左にずらした結果、左顎関節に緊張が生じた。−電位が生じると、左右電極間の電位差は負−Ａ（Ｌ）となる。右顎関節に緊張が生じた場合は、正＋Ａ（Ｌ）となる。この電位差変化値をＸ軸にとる。図２４は、その電位差変化値をＸ軸に示した３次元座標を表す。
（４）下顎を右にずらす
右顎関節に緊張が生じた場合、右顎関節が左に常時ずれていたのが、下顎を右にずらした結果、右顎関節に緊張が生じた。電位差変化は正＋Ｂ（Ｒ）となる。左顎関節に緊張が生じた場合は、負−Ｂ（Ｒ）となる。この電位差変化値をＸ軸にとる。図２５は、その電位差変化値をＸ軸に示した３次元座標を表す。
（５）下顎を前にずらす
左顎関節に緊張が生じれば、常時、左顎関節は後ろにずれていたことがわかる。電位差は負−Ａ（Ｆ）となる。右顎関節に緊張が生じれば、常時、右顎関節は後ろにずれていたことがわかる。電位差変化は正＋Ａ（Ｆ）となる。この電位差変化をＺ軸にとる。図２６は、その電位差変化値をＺ軸に示した３次元座標を表す。
（６）下顎を後ろへずらす
左顎関節に緊張が生じれば、左顎関節は、常時、前にずれていたことがわかる。電位差は負−Ｂ（Ｂ）となる。右顎関節に緊張が生じれば、右顎関節は、常時、前にずれていたことがわかる。電位差は正電位＋Ｂ（Ｂ）となる。この電位差変化をＺ軸にとる。図２７は、その電位差変化値をＺ軸に示した３次元座標を表す。
以上は、１つの咬合変化についての電位差変化値を３次元座標に示した。次に、複雑な咬合変化をした場合の実例を述べる。
下顎が後ろへずれて常時噛みしめている場合、口を開けて下顎を下げると左顎関節に緊張が生じ、下顎を前へずらすと左顎関節に緊張が生じ、下顎を右にずらすと左顎関節に緊張が生じて、それぞれに図２８に示すように電位差は負変化が生じる。これを３次元座標に記すと、図２９に示すようになる。
（Ｘ，Ｙ，Ｚ）＝（−４５ｍＶ，−４８ｍＶ，−３２ｍＶ）の位置に左顎関節が位置する状態を示している。First, measurement points for measuring the potential difference will be described.
(1) Two points on the left and right auditoriums. As shown in FIG. 1, the auditorium is on the skin directly above the temporomandibular joint and is a measurement point for diagnosing normality / abnormality of the temporomandibular joint.
(2) Two points for left and right stomach meridian (gastric well) and two points for right and left large intestine (colon well). The gastric meridian is a well in the base of the nail of the second finger, and the large intestine is a well in the base of the second finger nail. 2A and 2B show the positions of these gastric wells and large intestine wells.
It has been confirmed in many experiments that there is a close relationship between the maxilla and stomach, mandible and large intestine (Hiromoto Motoyama, Fumisada Ozawa collaborative research "Study on nerves and meridians with AMI" IV Chapter “Effects of Occlusal Treatment” pages 131-143 [Religious Psychology Publishing 1987]). Note that the large intestine and the stomach are also called “dental veins”.
It is known that a change in the lower jaw occlusion appears as a change in the BP current value in the colonic well, and an occlusal change in the upper jaw appears as a change in the BP current value in the gastric well. 3 and 4 are data obtained by examining the change in the BP current value in each well by placing electrodes in the gastric well and the large intestine through an AMI (meridian-organ function measuring device) and changing the occlusion. It is. The BP current value is a value of a current flowing in the dermis before polarization occurs in the epidermis basement membrane in response to skin stimulation, and is a meridian function parameter.
3 and 4, the series 1 shows the BP value of the right gastric meridian, the series 2 shows the BP value of the left gastric meridian, the series 3 shows the BP value of the right large intestine, and the series 4 shows the BP value of the left large intestine. Each is shown.
3 shows data when the tooth meshing position is changed back and forth, and FIG. 4 shows data when the lower jaw is shifted back and forth in the meshed state. The BP changes in the large intestine and stomach through the occlusal change shown in FIGS. 3 and 4 indicate changes in both the + side (BP increase) and the − side (BP decrease) by the difference in occlusion.
The present inventor further determined whether the changes in the auditory tract (corresponding to the temporomandibular joint), the large intestine transcutaneous hole (corresponding to the lower jaw), and the gastric transcutaneous hole (corresponding to the maxilla) are neurological or meridian. An experiment was conducted to confirm.
Stimulation due to occlusal changes is caused by the potential of the auditory shrine on the skin just above the temporomandibular joint, the potential of the large intestine transcutaneous hole at the base of the nail of the second finger of the hand, It is investigated whether or not the potential shows a change in the direction of the + side or the − side, and whether it is a change due to transmission of nervous system information or a change due to transmission of meridian system information about 11 subjects A to K. It investigated with the following method.
In this method, the occlusal diagnosis apparatus of the present invention was used. FIG. 5 is a block diagram showing the basic configuration of the occlusion diagnostic apparatus. This occlusal diagnosis device basically includes a potentiometer 8 and a calculation device 20.
The potentiometer 8 includes a high impedance amplifier 10, a differential amplifier 12, an insulation amplifier 14, a low pass filter 16, and an A / D converter 18. The computing device 20 is configured by a personal computer (PC).
The high impedance amplifier 10 is connected to a plurality of sets of measurement electrodes composed of the + side electrode 2 and the − side electrode 4 and one ground electrode 6 via respective lead wires.
FIG. 6 shows a circuit diagram of the potentiometer 8. In FIG. 6, only a circuit for one set of measurement electrodes 2 and 4 is shown to simplify the drawing. The high impedance amplifier 10 has two amplifiers 10A and 10B. The potential detected at the + side electrode 2 is connected to the + side input terminal of the differential amplifier 12 via the amplifier 10A, and the potential detected at the − side electrode 4 is connected to the differential amplifier 12 via the amplifier 10B. Connected to the negative input terminal.
The differential amplifier 12 takes the difference between these two inputs and inputs the difference output to the isolation amplifier 14. The insulation amplifier 14 has a light emitting element 14A and a light receiving element 14B, and once converts the difference output of the differential amplifier 12 into an optical signal, and then converts it back into an electrical signal and outputs it. The low pass filter 16 removes high frequency noise and inputs it to the AD converter 18. The AD converter converts the analog signal from the low-pass filter 16 into a digital signal and inputs it to the personal computer 20.
In addition, the existing potentiometer 8 of the above structures can be used.
Before the measurement using the above-described occlusion diagnostic apparatus, the potentiometer is adjusted to zero. The zero point adjustment is performed by bringing the positive electrode 2 and the negative electrode 4 into contact with each other and setting the potential difference output to zero.
Next, of the two electrodes, the -side electrode 4 is shorted to the ground, and only the + side electrode 2 is applied to the left auditory shrine, the left gastric well, and the left colonic well, and the lower jaw is bitten and opened. , Left, right, forward, backward to change the occlusion, and whether the stimulation due to the occlusal change causes negative or positive, or both positive and negative potential changes at the above three measurement points I investigated.
If it is a neural reaction, the potential change due to nerve excitation is always a negative potential change, and therefore, it should appear as a negative potential change at all three measurement points. If it is a meridian change, it appears as a negative or positive potential change. The meridian response is characterized by a slight stimulus such as a change in occlusion, even if the stimulus is not felt weakly, unlike the response of the nerve, where no response is given unless the stimulus is felt. Even a stimulus that does not feel any pain is to react.
Table 1 shows the frequency of positive potential change (+) and negative potential change (−) at each measurement point obtained by performing an occlusal change test on 11 subjects. For one subject who showed + change, -change, both at each measurement point, both were added to the frequency.
Figure 2005025444
Table 2 shows the change in potential of each subject A to K.
Figure 2005025444
The above-mentioned 11 subjects have + or at the auditorium (temporomandibular joint), gastrostomy well (upper jaw), large intestine transcutaneous hole (mandible) for the occlusal change stimulus due to the shift of the lower jaw to the front, rear, left and right, up and down Table 3 shows the potential change of −.
Figure 2005025444
Even if this is a χ 2 test with an m × n contingency table, as seen in Table 4, the + change frequency and the −change frequency are almost the same, and there is a significant difference between + change, −change, and no change. Is not seen. This indicates that the change caused by the occlusal change stimulus is not always a change due to a neural response indicating a -potential change.
Figure 2005025444
In addition, each time the occlusal change is made through each person's data, there is a + change or-change at the temporomandibular joint measurement point (audience), the maxillary measurement point (gastric transcutaneous hole), and the mandibular measurement point (colon transcutaneous hole). It is done. This indicates that changes in occlusion in the upper and lower jaws cause potential changes in a few seconds through the meridians that are different from those of the nervous system, in the auditorium, gastrostomy well, and colonic well. The reason is that the maxilla, mandible, and temporomandibular joint are the dominant regions of the trigeminal nerve, and the colonic and gastrointestinal cavities are not directly related to the distribution of the trigeminal nerve. The upper jaw is governed by the stomach and the lower jaw is governed by the colon. In addition, since the potential change at the auditorium also shows changes of + and-, this is also not a neurological thing and is considered to be a meridian change.
FIG. 7 shows an output waveform of the subject B's occlusion diagnostic apparatus. In the case of this test subject, the maxillary canine is an incisor, which may cause abnormalities in the maxilla, but the occlusal change (biting → opening the mouth → shifting the lower jaw to the left → shifting the lower jaw to the right → moving the lower jaw forward By shifting → lower jaw later), a large positive potential change is seen in the gastric meridian related to maxillary occlusion. At the auditorium, a negative potential change of -0.002 V is seen until the end after chewing.
FIG. 8 shows an output waveform of the subject G occlusion diagnosis apparatus. In the case of this subject, a remarkable positive potential change is observed in the large intestine every time the occlusion changes. In the auditorium, if it is shifted backward, it is -0.02 V, and a negative potential change occurs.
FIG. 9A and FIG. 9B show the results of performing a t-test to see a significant difference based on the output of the subject G's occlusion diagnosis apparatus. This t-test is performed by the personal computer 20. FIG. 9A shows the result of the t-test when biting, and FIG. 9B shows the result of the t-test when the lower jaw is shifted backward.
FIG. 10 shows the output of the subject A's occlusion diagnosis apparatus. In this test subject, positive and negative potential changes are not so much observed for occlusal changes, but slight positive or negative potential changes, 0.001 V or less or no change for occlusal changes in the temporomandibular joint, maxilla and mandible. Show.
As described above, it was confirmed that the potential change at the measurement points of the auditory palate, stomach, and large intestine was due to the meridian system.
Next, examples of the present invention will be described in detail. The occlusal diagnosis apparatus of the present invention is shown in FIGS. The occlusion diagnosis and the occlusion data measurement method described below are performed using this occlusion diagnosis apparatus.
First, in the potentiometer, zero point adjustment is performed. The zero point adjustment is performed by bringing the positive electrode 2 and the negative electrode 4 into contact with each other and setting the potential difference output to zero.
Next, each + side electrode 2 is attached to the left hearing hall, the left large intestine transcutaneous hole, and the left gastric transversal hole. Each negative electrode 4 is attached to the right hearing hall, the right large intestinal well, and the right gastric well. A ground electrode 6 is attached to the wrist. Then, the potential difference between the left and right auditory palaces, the potential difference between the left and right large intestine transcutaneous holes, and the potential difference between the left and right gastric transversal wells are measured simultaneously. In this case, continuous measurement is performed in units of 0.1 seconds, and measurement values are taken into the computer 20 in units of 1 second.
In the potentiometer 8, the potential at the measurement point detected by the + side electrode 2 and the − side electrode 4 is amplified by the high impedance amplifier 10, and then the potential difference is obtained by the differential amplifier 12. The potential difference is sent to the low-pass filter 16 through the insulation amplifier 14, and after removing the high frequency component, the analog signal is converted into a digital signal by the A / D converter 18 and supplied to the personal computer 20.
The measurement is performed in the following order. (1) Resting state (30 seconds), (2) Chewing (30 seconds), (3) Resting state (30 seconds), (4) Opening the mouth (30 seconds), (5) Resting state (30 seconds), (6) Shift the lower jaw to the left (30 seconds), (7) Rest state (30 seconds), (8) Shift the lower jaw to the right (30 seconds), (9) Rest state (30 seconds), (10) Lower jaw (11) Resting (30 seconds), (12) Shifting the lower jaw back (30 seconds).
Continuous data is extracted as a waveform graph according to a program installed in the personal computer 20. In addition, the measured value (potential difference) every second is t-tested (sees the significant difference) according to the program installed in the personal computer for the measured value in the resting state and the measured value at the change of occlusion. (As shown in FIG. 15 described later).
Based on the waveform graph and / or t-test table extracted as described above, diagnosis of occlusion normality / abnormality is performed by a program installed in a personal computer.
The criteria for occlusion diagnosis in such a program are as follows.
1) If the potential difference between the left and right electrodes in the first resting state is outside the range of ± 0.05 V (50 mV), it is regarded as abnormal muscle tension and occlusion, and if within the range, it is regarded as normal.
2) When changing the occlusion such as biting, opening the mouth, shifting the lower jaw to the front, back, left, right, etc. If a significant difference (t-test) is observed with the potential difference at the time of change, it is determined that the occlusion is abnormal.
3) If there is no abnormality in the occlusion, there is no significant change due to the change in the occlusion, and the base line of the waveform graph is close to 0V.
A diagnostic method using a program based on the above diagnostic criteria will be described.
1) Judgment of normal / abnormal temporomandibular joint, maxillary and mandibular occlusion in a resting state is judged normal if the potential difference between the left and right electrodes of the temporomandibular joint, maxilla and mandible is within ± 0.05 V (50 mV). . If it is out of range, it is determined that the occlusion is abnormal.
2) Judgment at the time of changing occlusion By changing the occlusion, such as biting, widening the mouth, shifting the lower jaw to the left or right, front or back, etc. If the potential difference changes to the-side or the + side in any of the cases, and a significant difference is seen by the t-test, if it is an auditory papillary, the temporomandibular joint is abnormal. Then, it is determined that there is an occlusal abnormality in the lower jaw.
As a comprehensive judgment, if the occlusion is changed up and down, front and back, and left and right at three measurement points, if the maximum and most potential changes occur in the gastric well, it is determined that the occlusal abnormality is maximum in the maxilla . The same judgment is made for the large intestinal trans-well and auditorium.
However, in the case of the auditorium, not only changes in the potential difference due to meridian reaction, but also abnormalities in the temporomandibular joint, and if there is tension in the muscles around the temporomandibular joint, it is expected that a negative potential will be generated in the muscle due to the occlusal change .
Next, the data of each subject is shown and an example of diagnosis is shown.
11 and 12 are diagrams illustrating output waveforms of the potential difference of the subject I. FIG. When FIG. 11 is seen, it is + 0.05V (+ 50mV) or more in a large intestine transcutaneous hole at the time of an initial resting state. As can be seen from FIG. 12, the sound level at the first resting state is shifted to −0.56 V, which is −0.56 V. From the above, it is considered that this subject has an abnormality in the lower jaw and temporomandibular joint. When the lower jaw is moved forward, it changes 0.02V larger to the + side at the auditorium. In this case, the muscle around the right temporomandibular joint is strained and -potential is generated, and the potential difference is changed to the + side. Therefore, it is determined that the right temporomandibular joint is abnormal. In this potentiometer, since the left electrode is the + side electrode and the right electrode is the-side electrode, if a -potential change occurs in the left electrode, the potential difference changes to the-side, and a-potential change occurs in the right electrode. Then, the potential difference changes to the + side.
FIG. 13 is a diagram illustrating an output waveform of the potential difference of the subject K. The subject had the right lower back tooth extracted, and the occlusion was not normal. Biting from the first resting state, there is no change until the mouth is opened, but when the lower jaw is shifted left and right, back and forth, the temporomandibular joint, maxilla and mandible are markedly changed (about 0.02V to 0.025V or more) on the + side Has occurred. This indicates that the entire occlusion is abnormal. Abnormality in the right temporomandibular joint can be considered from the change in potential difference to the + side of the auditorium.
FIG. 14A, FIG. 14B, and FIG. 14C are data showing the results of this subject's K-test. FIG. 14A shows the data for the auditory shrine, FIG. 14B shows the data for the gastric well, and FIG. 14C shows the data for the colonic well.
FIG. 15 is a diagram showing an output waveform of the subject L (not shown in Table 2). This test subject had already extracted both wisdom teeth. In all of the resting state and the occlusal change, the change of + and − is ± 0.02 V centering on the baseline 0 V, and it can be seen that there is no abnormality in the occlusion as a whole.
16 and 17 are diagrams showing output waveforms of the subject H. FIG. Referring to FIG. 16, the output of the auditorium is -0.025 V, and does not show much change even with occlusal changes. Although the output of the large intestine transcutaneous hole (mandible) is little changed by the occlusal change, the base line is in the vicinity of −0.18 V, and when looking at FIG. 17, the gastric transgastric hole (maxillary) is in the vicinity of the base line +0.35 V.
As a comprehensive judgment, both the upper jaw and the lower jaw have a difference in occlusion, but this is a long-standing habit, and it seems that occlusal abnormalities are not so much seen in the temporomandibular joint.
The above is the diagnosis of occlusion normality / abnormality by potentiometer output data and / or t-test.
Next, as a special case, an output waveform of a subject wearing a sprint is taken, and the result of examining the change in the waveform will be described.
First, a toothless sprint was attached and a waveform was taken. FIG. 18 shows the waveform. Looking at the waveform before the occlusal change, the potential difference is-in the auditory hall indicating the state of the temporomandibular joint. This indicates that there is tension in the muscles of the left temporomandibular joint.
A fit checker was collected from a test subject wearing a splint without teeth and chewing. FIG. 19 shows a photograph of the fit checker. In the fit checker, the left temporomandibular joint is low and the left temporomandibular joint appears to be tense. It can be seen that this is consistent with the examination by the waveform.
Next, looking at the response to the occlusal change of opening and closing the jaw, opening the mouth caused tension in the left and right temporomandibular joints. This is because the whole occlusion is low and I am used to always biting, so it seems that tension occurred when I opened my mouth. Next, when the lower jaw was shifted to the right, tension occurred in the right temporomandibular joint. This is because the lower jaw is always shifted to the left, and when it is shifted to the right, the right temporomandibular joint is considered to be strained.
From the above results, the occlusion is low overall, the left temporomandibular joint is lower than the right temporomandibular joint, and the lower jaw is shifted to the left. Therefore, there is tension in the left temporomandibular joint before the occlusal change, and the lower jaw is shifted to the left. Therefore, it seems that the right temporomandibular joint is likely to be strained even if it is opened or shifted to the right.
The potential difference of the colonic well, which is a parameter of the lower jaw, and the potential difference of the gastric well, which is a parameter of the upper jaw, are positive.
Next, a splint with teeth was attached and a waveform was taken. FIG. 20 shows the waveform.
A fit checker was collected from a test subject wearing a splint with teeth and chewing. FIG. 21 shows a photograph of the fit checker. There is a hole on the left side, but no hole on the right side, so you can see that the right temporomandibular joint is low.
Looking at the waveform of FIG. 20, contrary to the waveform of FIG. 18 when a sprint without teeth is worn, the data before the occlusal change shows a positive (2 to 3 mV) potential difference at the auditorium. This indicates a slight strain on the right temporomandibular joint. It matches the data of the fit checker. When the mouth was opened, it decreased slightly by 1 mV. There is almost no response to other bite changes. Therefore, the occlusion is considered to be normal.
Next, three-dimensional analysis and diagnosis of the temporomandibular joint will be described. A + side electrode 2 is attached to the left hearing hall of a subject, and a-side electrode 4 is attached to the right hearing hall. The mandible is moved up and down, left and right, and back and forth, and the movement of the temporomandibular joint is analyzed using XYZ three-dimensional coordinates. The left-right direction is the X axis, the up-down direction is the Y-axis, and the front-back direction is the Z-axis. The situation of the temporomandibular joint and the surrounding muscles that move it can be seen in the auditorium. Such coordinate analysis is realized by a program installed in the personal computer 20.
Hereinafter, a description will be given corresponding to an example of occlusal change.
(1) Biting Tension occurred at the left temporomandibular joint. This is because the left temporomandibular joint is always open and tension is generated in the biting direction. When tensioned, a -potential is generated If the left temporomandibular joint is negative, the potential difference between both electrodes is negative -A (cl), and if the right temporomandibular joint is negative, the potential difference between both electrodes is positive + A (cl).
The negative and positive potential difference change values are taken on the Y axis. FIG. 22 shows three-dimensional coordinates in which the potential change value is indicated on the Y axis.
(2) Open mouth wide Tension occurs in any of the left and right temporomandibular joints and the surrounding muscles. This is because the temporomandibular joint is accustomed to the direction of closing at all times, but because it opened, tension occurred.
In the case of left temporomandibular joint tension, the left temporomandibular joint was in a direction that was always closed, but the left temporomandibular joint was strained because it was opened. The potential difference is negative -B (0). In the case of the right temporomandibular joint tension, the right temporomandibular joint was in a direction that was always closed, but since it was opened, the right temporomandibular joint was strained, and the potential difference was positive + B (0). This potential difference change value is taken on the Y axis. FIG. 23 shows three-dimensional coordinates in which the potential difference change value is indicated on the Y axis.
(3) Shifting the lower jaw to the left When the left temporomandibular joint was strained, the left temporomandibular joint was always shifted to the right, but as a result of shifting the lower jaw to the left, the left temporomandibular joint was strained. When a potential is generated, the potential difference between the left and right electrodes is negative -A (L). When tension occurs in the right temporomandibular joint, it is positive + A (L). This potential difference change value is taken on the X axis. FIG. 24 shows a three-dimensional coordinate in which the potential difference change value is shown on the X-axis.
(4) Shifting the lower jaw to the right When the right temporomandibular joint was strained, the right temporomandibular joint was always shifted to the left, but as a result of shifting the lower jaw to the right, the right temporomandibular joint was strained. The potential difference change is positive + B (R). When tension occurs in the left temporomandibular joint, it is negative -B (R). This potential difference change value is taken on the X axis. FIG. 25 shows three-dimensional coordinates in which the potential difference change value is indicated on the X axis.
(5) Shifting the lower jaw forward If tension occurs in the left temporomandibular joint, it can be seen that the left temporomandibular joint has always shifted backward. The potential difference is negative -A (F). If tension occurs in the right temporomandibular joint, it can be seen that the right temporomandibular joint has always shifted backward. The potential difference change is positive + A (F). This potential difference change is taken on the Z axis. FIG. 26 shows three-dimensional coordinates in which the potential difference change value is indicated on the Z axis.
(6) Shifting the lower jaw backward If tension occurs in the left temporomandibular joint, it can be seen that the left temporomandibular joint has always shifted forward. The potential difference is negative -B (B). If tension occurs in the right temporomandibular joint, it can be seen that the right temporomandibular joint has always shifted forward. The potential difference is a positive potential + B (B). This potential difference change is taken on the Z axis. FIG. 27 shows a three-dimensional coordinate in which the potential difference change value is indicated on the Z axis.
The above shows the potential difference change value for one occlusal change in three-dimensional coordinates. Next, an example of a complicated occlusal change will be described.
If the lower jaw is displaced backwards and biting continuously, opening the mouth and lowering the lower jaw will cause tension in the left temporomandibular joint. Tension is generated in the joint, and a negative change occurs in the potential difference as shown in FIG. When this is described in three-dimensional coordinates, it becomes as shown in FIG.
This shows a state in which the left temporomandibular joint is located at a position of (X, Y, Z) = (− 45 mV, −48 mV, −32 mV).

本発明によれば、左右聴宮，左右胃経井穴，左右大腸経井穴の各電位差の変化から、咬合の異常・正常を、正確に診断できる装置を提供し、この装置を用いての咬合診断が可能になった。  According to the present invention, it is possible to provide a device capable of accurately diagnosing occlusion abnormality / normality from changes in potential differences between the left and right auditory tracts, left and right gastric wells, and left and right colorectal wells, and occlusion using this device. Diagnosis is now possible.
