Abstract
Description
本発明は、下顎の安定位置を保持し、食いしばりなど非日常的な負荷力から大臼歯の摩耗と接壊を防ぐためのマウスピースに関するものである。 The present invention relates to a mouthpiece for maintaining a stable position of the lower jaw and preventing wear and breakage of molar teeth from extraordinary load forces such as clenching.
従来のスポーツ用マウスピースにおいては、上歯列全体に巻着させるもので、基本形は平面において水平形状をもち、利用者が歯型の転写後、歯列に密着させて歯をガードするモノである。 Conventional sports mouthpieces are wound around the entire upper dentition, and the basic shape is a flat horizontal surface, and the user guards the teeth by closely contacting the dentition after transferring the tooth shape. is there.
従来品は、上歯並び全体に嵌着する仕組みであるため、基本形に上歯並び全体の歯型転写を行う必要があり、利用者が、その素材の軟化と硬化で型作りを行う、その過程で、諸着のフィット感を容易に得る事ができず、使用できるまでの型取りの作業に慣れるまで時間と手間を要する。 Since the conventional product is a mechanism that fits the entire upper teeth arrangement, it is necessary to transfer the tooth pattern of the entire upper teeth arrangement to the basic shape, and the user creates a mold by softening and hardening the material. It is difficult to obtain a fit of various clothes, and it takes time and effort to get used to the mold making work until it can be used.
水平形状の基本形において、食いしばりなど、咀嚼以外の非日常的な大きな力を受ける時、斜め曲線状にある大臼歯の並び位置は、下顎の持つ斜め曲線にそぐわせ難い型となっている。負荷力を受ける優先順位の高い位置にある大臼歯が、小臼歯、前歯との高さに差が無く、水平構造の形を曲線に嵌めこむ事ができても大臼歯の位置に隙間が生じる結果となる。また、歯並び全体に被着させる型は着脱を困難にさせ、話す必要のある運動場所では不便で、実用的とはいえず、特殊なスポーツ従事者専用のものという域から抜けられない。 In the horizontal basic shape, when receiving an extraordinary force other than mastication, such as clenching, the alignment positions of the molars in the diagonal curve are difficult to match the diagonal curve of the lower jaw. There is no difference in the height of the premolar and anterior teeth in the high-priority position where the load force is received, and there is a gap in the position of the molar even if the shape of the horizontal structure can be fitted into the curve Result. In addition, the mold attached to the entire tooth arrangement makes it difficult to attach and detach, is inconvenient in an exercise place where it is necessary to speak, is not practical, and cannot be removed from the area dedicated to special sports workers.
従来のマウスピースには次のような欠点があった。
・最も奥の大臼歯にフィット感が得にくい。
・使用前の作業時間がかかる。
・着脱に手間がかかる。
・一般の利用者が気軽に扱えない。
The conventional mouthpiece has the following drawbacks.
・ It is difficult to get a fit on the deepest molars.
・ Work takes time before use.
・ It takes time to attach and detach.
・ Cannot be handled easily by general users.
人の下顎は斜め曲線を持つ形態であり、歯並びはその上に生えている。水平形状を歯並びに被せ、嵌めこむことは可能である。しかし、頭部の後方傾斜で下顎を上向かせ水平に保ち、上歯列で従来品を咬持しなければならず、下顎に力を入れての型取りでは、下顎の本来の位置とは異なるものになる。身体構造に見る本来の下顎の位置と下顎関節の位置は、図４に示す通り、人の無理のない平時の姿勢は頭部が俯き、平時姿勢の閉口時の顎関節部は、図４の４、の下顎頭の位置と、図４の５、上下奥大臼歯の噛み合う位置で釣り合いがとれる。無理に水平型に合わせようと下顎を移動させると、下顎の位置は喉側へ自動的に移行し、下顎の移行した分、上下大臼歯との噛み合わせ位置に変化が生じ、不釣り合いな位置で固定することに繋がる。 The man's lower jaw is a form with an oblique curve, and the tooth arrangement grows on it. It is possible to put the horizontal shape over the teeth and fit. However, it is necessary to hold the conventional product with the upper dentition with the lower jaw facing upward by tilting the back of the head, and in the mold making with force applied to the lower jaw, what is the original position of the lower jaw? It will be different. As shown in FIG. 4, the original mandibular position and mandibular joint position as seen in the body structure are as follows. There is a balance between the position of the lower mandibular head 4 and the position 5 of FIG. When the mandible is moved to force it to fit the horizontal type, the position of the lower jaw automatically shifts to the throat side, and the position of meshing with the upper and lower molars changes as much as the lower jaw moves, resulting in an unbalanced position It leads to fixing with.
下顎の自由な運動には、口の開閉時のあらゆる運動に伴う可動域が存在し、下顎関節部の特殊性が下顎の動きを支える。下顎頭拡大図６にみる（ア）１０の下顎頭が図６（ア）９の下顎窩において閉口とし、本来の運動開始前の状態でもある。図６（イ）に示す１０から１１を下顎の開閉時の運動軌跡とし、自由な運動がある。俯いた姿勢で、斜め角度を持つ下顎を水平に移動することは頭部の後方傾斜を持って成され、頭部の移動は下顎の喉側移行と見なさなければならない。下顎の喉側移動は、図６（ウ）の１０から１２、へと下顎頭も移行し、図６，９に示す、本来の下顎窩ではない位置、図６（ウ）１４の関節壁部分に下顎頭の位置は近づく。水平状態で下顎に力を入れ、歯型を転写し、型作り、咬合位置を固定した状態で平時姿勢に戻ると、マウスピースで咬止した状態が、顎頭を本来の位置に戻りにくくし、運動時の食いしばりは、固定された下顎頭の移行した位置での咬合になる。下顎は、頭部と一体化している上顎とは異なり、稼働可能な仕組みを持ち、簡単に前後左右上下に移行する。頭部の後方傾斜に依る上下顎の位置のずれ易さは、上下大臼歯の噛み合わせ位置のずれ易さにもつながる。図４の５、に示す、平常時の釣り合いのとれた位置で力を受け、力を受ける優先順位の高い歯の保護を可能にする必要がある。下顎のもつ斜め曲線とその上に生える上下大臼歯の本来の噛み合う位置で利用できるマウスピースには、下顎の斜め曲線を考慮し、安定と釣り合いのとれる位置を守ることで、本来の力の発揮と負荷力の分散に矛盾しない咬合位置での食いしばる仕組みを作り出す事が可能になる。 The free movement of the lower jaw has a range of motion associated with every movement when opening and closing the mouth, and the speciality of the lower jaw joint supports the movement of the lower jaw. As shown in FIG. 6 (a), the mandibular head of 10 is closed in the mandibular fossa of FIG. 6 to 11 shown in FIG. 6 (a) are movement trajectories when the lower jaw is opened and closed, and there is free movement. Moving the lower jaw with an oblique angle horizontally in a crawling posture is done with a backward tilt of the head, and the movement of the head must be regarded as a transition to the throat side of the lower jaw. The movement of the lower jaw on the throat side also moves from 10 to 12 in FIG. 6 (c), and the mandibular head also moves to a position that is not the original mandibular fossa, as shown in FIGS. The position of the mandibular head approaches. Applying force to the lower jaw in a horizontal state, transferring the tooth mold, making the mold, and returning to normal posture with the occlusal position fixed, the state of being bitten by the mouthpiece makes the chin head difficult to return to its original position The clenching during exercise becomes an occlusion at the transitional position of the fixed mandibular head. Unlike the upper jaw that is integrated with the head, the lower jaw has a mechanism that can be operated, and easily moves back and forth, right and left, and up and down. The ease of shifting the position of the upper and lower jaws due to the backward inclination of the head also leads to the ease of shifting the meshing position of the upper and lower molars. It is necessary to receive a force at a balanced position in a normal state as shown in 5 of FIG. 4 and to protect a high priority tooth receiving the force. The mouthpiece that can be used in the original meshing position of the lower jaw and the upper and lower molars that grow on the lower jaw takes into account the lower jaw's oblique curve and protects the position where it can be balanced with stability, thereby demonstrating the original power. It is possible to create a clenching mechanism at the occlusal position that is consistent with the distribution of load force.
請求項１に示す本発明は、斜め曲線上の大臼歯を重点的に保護する形である。弾力性を持つ保護素材で力の集中する大臼歯の咬合位置に挟持し、噛む時、必要最低限の高さが、他の歯の高さも同時に上げるので食いしばり時の力の被害を受ける事を避ける仕組みになっている。咀嚼とは異なる上下だけの運動は力のほとんどを大臼歯が受ける。非日常的力から受ける摩耗、接壊を避ける仕組みとなっている。下顎の運動動線から生まれる下顎頭の軌跡上での運動力は、大きな咬筋を主力に、下顎の傾斜と図６、（ア）９、にみる上顎関節部分の壁の窪みの高さから生みだされる。噛み砕く咀嚼力や、食いしばりの大きな力を発揮するしくみである。出力と同時に負荷力を受けるためのクッション位置にもなっている下顎・下顎頭の帰着する位置は、図６、（ア）９、１０、であり、大臼歯も力を受ける為の最も合理的仕組みとして他の歯とは異なる、歯の大きさ、歯茎の厚さなどで対応できる。 The present invention according to claim 1 is a form in which the molars on the oblique curve are preferentially protected. When holding and biting at the occlusal position of the molar where the force is concentrated with a protective material with elasticity, the minimum height is also raised simultaneously with the height of the other teeth, so that it will be damaged by clenching force It is a mechanism to avoid. Different from chewing, only the upper and lower movements receive most of the force in the molars. It is a mechanism that avoids wear and damage caused by extraordinary forces. The movement force on the trajectory of the mandibular head born from the movement line of the mandible is produced from the inclination of the mandible and the height of the dent of the wall of the maxillary joint as seen in FIG. It will be. It is a mechanism that exerts the chewing power to crush and the great power of clenching. The positions where the lower jaw and mandibular head, which are also cushioned positions for receiving load force at the same time as the output, return to FIG. 6, (A) 9, 10 and are the most reasonable for the molars to receive force as well. The mechanism is different from other teeth, such as the size of the teeth and the thickness of the gums.
斜め曲線の下顎の上に生える大臼歯の噛み合う位置は、上の大臼歯との咬合位置を保持することでその帰着位置に下顎頭が納まるよう連動している。僅かな頭部後方傾斜でも、下顎に連なる舌の筋肉、咬筋、喉、首など筋力の複雑な動きが影響し、図６（ア）９，１０の示す帰着位置とは異なる位置、図６(ウ)１２と１４に下顎・下顎頭は移動する。その位置で強い負荷をかける事にならなければ問題は無いが、本来の帰着位置とは異なる位置で咬合し食いしばると、その力を受ける時、本来とは異なった位置で負荷力を受ける事になる。 The position where the molar teeth that grow on the lower jaw of the oblique curve are interlocked with each other so that the mandibular head fits into the return position by maintaining the occlusal position with the upper molar. Even if the head is tilted slightly backward, complex movements of muscle strength such as the muscles of the tongue, masseter, throat, and neck that are connected to the lower jaw affect the position, which is different from the return position shown in FIGS. C) The mandible and mandibular head move to 12 and 14. There is no problem if a strong load is not applied at that position, but if you bite and bite at a position different from the original return position, you will receive a load force at a position different from the original when receiving that force. Become.
下顎の本来の位置を保持する目的のため、図５（ア）の８に示す、奥大臼歯の咬合位置となる矩形状を、上下奥大臼歯の間に添着し、図５（ア）の７、７´の、楔形が隣接する大臼歯に接する位置とし、奥大臼歯の咬合接触を邪魔しないよう工夫した。日常的に起こる食いしばりや咀嚼による自然摩耗や人工的摩耗で引き起こされている奥大臼歯の高さ不足がある場合、咬合時の大臼歯にかかる圧力は奥大臼歯にあり、楔形に接触する位置にある隣接大臼歯は楔形にかろうじてするだけである。しかし、奥大臼歯が本来の高さより低くなっている場合、隣接する大臼歯に重点的に力が加わり、上下奥大臼歯の間に隙間が生じる。図５（ア）８の高さを上げ奥大臼歯が優先的に接触できるよう調節する必要がある。楔形の位置にある隣接大臼歯の接触状態が高さ不足を計る目安になる。基本型を作る目安を示しているが、図５（ア）の必要とする数値、１５ｍｍ×１５ｍｍ×４ｍｍとする４ｍｍの厚みと半径の持つ数値を変えることで、男女、年齢、から来る違いに対応することが可能になった。 For the purpose of maintaining the original position of the lower jaw, a rectangular shape as shown in 8 of FIG. 5 (a), which is the occlusal position of the back molar, is attached between the upper and lower back molars, as shown in FIG. 5 (a). 7 and 7 'were positioned so that the wedge shape touches the adjacent molars, so that the occlusal contact of the back molars was not disturbed. If there is insufficient height of the back molar caused by natural wear or artificial wear due to clenching or chewing that occurs on a daily basis, the pressure applied to the molar at the time of occlusion is in the back molar and the position where it contacts the wedge shape Adjacent molars are barely wedge-shaped. However, when the back molar is lower than the original height, a force is applied to the adjacent molars, and a gap is generated between the upper and lower back molars. It is necessary to adjust the height of FIG. 5A to 8 so that the back molar can be contacted preferentially. The contact state of the adjacent molars in the wedge-shaped position is a measure for measuring the lack of height. It shows the standard to make the basic mold, but by changing the numerical value of 4mm thickness and radius of 15mm x 15mm x 4mm required in Fig. 5 (a), the difference coming from gender and age It became possible to respond.
下顎頭を支点とした下顎の咀嚼運動を考える時、下顎運動の仕組みをテコの原理を用いて説明ができる。非特許文献１の吉田勘持著「構造医学」エンタプライズ出版 2007年発行、１２４ｐ。力の効果を受ける作用点上にある歯並び、その中でも大臼歯は、他の歯より支点に最も近く、負荷力を受ける優先順位の上位にある。下顎頭の位置と大臼歯の高さが、釣り合いのとれた状態で保たれる時、人はリラックスした状態にあり、上下の第３大臼歯は、食いしばることなく軽く触れ合う位置を保つことができる。つまり、奥大臼歯の上下の高さも優先的に負荷を受け易い位置にある、下顎の位置、下顎頭の位置、上下の大臼歯が本来の位置で噛み合うことは、効率の良い咀嚼と個体運動能力の発揮できる為の必須条件である。リラックスした状態の姿勢で、個体の持つ釣り合いのとれた位置には、本人が確認し認識できるため、無理な力で噛み合わせ位置を作る必要はなく、閉口時のリラックスした姿勢の下顎の位置に、負荷力を受けることになる優先順位に準じた歯に、最小数値を求めた保護素材をあてがうことは、優先順位の高い歯をも守ることと同時に、斜め曲線上にあるその他の歯の高さを上げることにもつながり、不必要な歯の接触を防ぐことに繋がる。 When considering the chewing movement of the lower jaw with the lower jaw as a fulcrum, the mechanism of the lower jaw movement can be explained using the lever principle. Non-Patent Document 1 Kanmo Yoshida “Structural Medicine” Enterprise Publishing 2007, 124p. Teeth arranged on the point of action that receives the effect of force, of which molars are closer to the fulcrum than other teeth and are higher in the priority order of receiving load force. When the position of the mandibular head and the height of the molars are kept in balance, the person is in a relaxed state, and the upper and lower third molars can maintain a lightly touching position without clenching . In other words, the upper and lower heights of the back molars are preferentially subject to load. The position of the lower jaw, the position of the mandibular head, and the upper and lower molars mesh in their original positions. It is a prerequisite for the ability to be demonstrated. In a relaxed posture, the individual's balanced position can be confirmed and recognized by the person, so there is no need to create a meshing position with excessive force, and the lower jaw position is relaxed when closing Applying a protective material with a minimum value to the tooth in accordance with the priority order that will be subjected to load force will protect the tooth with the highest priority, and at the same time the height of other teeth on the diagonal curve It also leads to an increase in height and prevents unnecessary tooth contact.
通常、上向きからうつむいた姿勢に戻ると、人の下顎は重力の重みで口側前方向へ 移動し、下顎・下顎頭は帰着位置に自然に戻る。その根拠を非特許文献１の吉田勘持著「構造医学」エンタプライズ出版 ２００７年発行 １１９ｐ〜１２１ｐに示す。従来品を使い、下顎に力を入れ咬合、上向き加減で成形、嵌着使用をした場合、頭部・下顎が俯いた状態になると、上下対で重なる曲線上の歯の噛み合わせは、下顎の移行した分だけ下大臼歯の位置が喉側奥へ移行する。同時に上大臼歯との咬合位置にずれが生じ、曲線上にある上下の歯並びの稜線の合う位置にも影響を与え、上下奥大臼歯の咬止間に隙間が生じる。負荷の掛かる優先順位の高い、大臼歯の咬止面に隙間のできた状態では、隣接歯、小臼歯、切歯部分のいずれかに負荷が掛かり、下顎の不安定が生まれる。安定した位置を得るまで下顎は前後左右に移動し、釣り合いを取り戻そうとする。他の歯の高さに合った安定を得る事はできるが、高さの変化した咬合は下顎頭の接触する関節壁への角度を変え、本来とは異なる新たな帰着位置で負荷を受けることに繋がる。本来なら運動時の食いしばりで増大させた負荷力は、支点に近い奥大臼歯が重点的に支え、受けた負荷力を複雑に絡む咀嚼筋を経て身体全体の筋肉に分散させる。身体への負荷力の正常な分散は、身体機能の効率の良い発揮と身体にかかる負担の軽減を行使する大切な仕組みとなっている。非特許文献１「アナトミートレイン」トーマス・Ｗ・ワイヤース著、医学書２００９発行、１７８ｐ、１８１ｐ、１９９ｐ、２０５ｐに示すように、身体構造上、不可欠な条件である。 Normally, when the posture returns from the upward direction, the human lower jaw moves to the front of the mouth with the weight of gravity, and the lower and lower jaw heads naturally return to the return position. The basis for this is shown in “Structural Medicine” Enterprise Publishing 2007, published by Kanji Yoshida, Non-Patent Document 1, 119p-121p. When using the conventional product, applying force to the lower jaw, occlusion, forming with upward adjustment, and using the fitting, when the head and lower jaw are in a crawled state, the engagement of teeth on the curved line overlapping the upper and lower pairs will be The position of the lower molar moves to the back of the throat side by the amount transferred. At the same time, a shift occurs in the occlusal position with the upper molar, affecting the position where the ridgelines of the upper and lower teeth on the curve meet, and a gap is created between the bites of the upper and lower molars. In a state where a high priority is placed on the load and there is a gap in the occlusal surface of the molar, a load is applied to any of the adjacent teeth, premolars, and incisors, resulting in instability of the lower jaw. Until the stable position is obtained, the lower jaw moves back and forth and left and right, trying to regain balance. Although it is possible to obtain stability suitable for the height of other teeth, the bite with the changed height changes the angle to the joint wall with which the mandibular head contacts, and is loaded at a new return position different from the original one. It leads to. Originally, the load force increased by clenching during exercise is mainly supported by the back molar near the fulcrum, and distributed to the muscles of the entire body through the masticatory muscles that entangle the load force intricately. The normal distribution of the load force on the body is an important mechanism for exercising efficient display of physical functions and reducing the burden on the body. Non-Patent Document 1 “Anatomy Train” by Thomas W. Wires, published by Medical Book 2009, 178p, 181p, 199p, 205p, is an indispensable condition in terms of body structure.
大臼歯の、本来の位置での咬止が出来ない時、大臼歯より負荷抵抗力の低い、作用点から離れる他の歯へ負担を増すことになる。一般に、咀嚼時に口の中に起こるベクトルは、下顎の円運動と複雑な表情筋や咬筋力によって支えられ、その力を受けた歯で咀嚼し、効率の良い力の伝播と分散を図っている。図６（イ）１０から１１に示す帰着経路とは異なる咬合位置での運動は、不釣り合いな咬合となり、口の中のベクトルの変化を作り出す。下顎頭の本来ある位置と大臼歯の高さの関係は、非特許文献１の吉田勘持著「構造医学」エンタプライズ出版 ２００７年発行、１２６ｐに見てとれる支点の存在から、テコの原理に基づいた釣り合う仕組みを持っており、図４の５に示す、上下大臼歯の本来の咬合位置と下顎の本来の位置は、咀嚼筋系統とともに、人体の仕組みの基本に組み込まれ、頭部重心の位置に密接に影響を与えている。図６（ア）に示す、閉口時の釣り合う下顎頭の位置から、図６（イ）１０から１１の開口までの過程範囲内で必要最小値の高さを求めることは、請求項１に示す曲線を持つ本発明に置いて、釣り合いのとれた状態を保つために、最小数値で大臼歯を負荷力から保護し、効率の良い力の分散を図る為の型を求めたものである。 When the molar cannot be bitten in its original position, the burden on other teeth away from the point of action, which has a lower load resistance than the molar, is increased. In general, the vector that occurs in the mouth during mastication is supported by the circular movement of the lower jaw and complex facial muscles and masseter muscle forces. . Movements at occlusal positions different from the return paths shown in FIGS. 6 (a) to 10 (11) result in an unbalanced occlusion and create a vector change in the mouth. The relationship between the original position of the mandibular head and the height of the molar is based on the principle of leverage from the existence of fulcrum that can be seen in Non-Patent Document 1 Kanji Yoshida “Structural Medicine” Enterprise Publishing 2007, 126p. The original occlusal position of the upper and lower molars and the original position of the lower jaw shown in 5 of FIG. 4 are incorporated into the basic mechanism of the human body, together with the masticatory muscle system, It has a close influence on the position. It is shown in claim 1 that the required minimum height is obtained within the process range from 10 to 11 in FIG. 6 (A) from the position of the mandibular head that is balanced at the time of closing shown in FIG. 6 (A). In the present invention having a curve, in order to maintain a balanced state, a mold for protecting the molar teeth from the load force with a minimum value and achieving an efficient force distribution is obtained.
瞬時の最大力を受ける位置には、負荷力に対する耐久度の優先順位も存在し、下顎頭を支点とした時、最も奥の大臼歯が優先的に力を引き受けることになり、歯茎の厚み、歯の面積の広さともに３本の大臼歯の存在は大きい。スポーツ利用のためのマウスピースの利用は、最も奥の大臼歯の本来の高さの維持と下顎を安定保持させた状態という本来の構造を維持し、運動することであるが、大半の人の大臼歯は、咀嚼時に受ける摩耗・加齢による自然摩耗や人工的摩耗でその高さを失っていると予測される。請求項２に置いて矩形と楔形を利用した本発明の型は、不必要な高さ上げが歯茎に負担をかける事に繋がる為に、本来の高さから不足した数値を知る工夫をする必要があった。隣接するその他の大臼歯との連携を強制力の無い型で、必要な範囲の高さを割り出すことを可能にしたものである。人は加齢に伴い摩耗する、その確率の高い奥大臼歯の高さ不足を補う事が、釣り合いを整える必須条件であるとして基本型にとりいれた。大臼歯以外の歯の高さを上げ負荷力を受けるということは、優先順位の低い歯に、非日常的な力を不必要に与え、不釣り合いを作り出す原因に繋がると判断した結果である。 In the position where the instantaneous maximum force is received, there is also a priority order of durability against load force, and when the mandibular head is used as a fulcrum, the deepest molars will preferentially receive the force, the thickness of the gums, The presence of three molars is large in terms of the area of the teeth. The use of a mouthpiece for sports is to maintain and maintain the original structure of maintaining the original height of the deepest molar and the mandible in a stable state. Molars are predicted to have lost their height due to natural wear and artificial wear due to wear and aging during mastication. The mold of the present invention using the rectangle and the wedge shape according to claim 2 needs to be devised to know the missing value from the original height, because unnecessary height increase will put a burden on the gums. was there. It is possible to determine the required range of height with a type without forcing to cooperate with other adjacent molars. It was adopted in the basic type as a necessary condition for balancing the balance of the lack of the height of the back molar, which is likely to wear with age. Increasing the height of the teeth other than the molars and receiving a load force is a result of determining that extraordinary power is unnecessarily applied to the low priority teeth, leading to a cause of unbalance.
第１，２，３大臼歯の三本は、下顎角の内側にあって、咬筋に囲まれ強い負荷力を担う位置にある。歯並びは、下顎上の歯茎に垂直に立ち喉側奥へ進むほど、厚い歯茎と歯肉に支えられ、下顎の斜め曲線上に大臼歯は生え、曲線を成す。咬む出力となる主力の咬筋が下顎横に広く結ばれこめかみへと続く。釣り合いのとれた咬み合わせの位置は、図４に示す、身体に対し斜め角度を持ち、上下の大臼歯が軽く触れ合う位置にあり、最も奥の大臼歯の高さと図６（ア）９、に示す下顎窩と図６（ア）１０の下顎頭の位置は密接に連なった関係にあり、咀嚼運動の主力となる咀嚼筋（「歯科技工士辞典」歯科薬出版株式会社2007年発行 ３１８ｐ、３１９ｐ）は、筋膜・筋肉を束ねる膜を通じて、身体の全身をめぐる筋力に繋がり、身体構造の釣り合いを保つ。下顎の安定した位置は身体バランスを保つ役割を果たすようである（「アナトミートレイン」トーマス・ｗ・マイヤース医学書院２００９年発行５ｐ、６ｐ） Three of the first, second, and third molars are inside the mandibular angle and are in positions where they are surrounded by the masseter muscle and bear a strong load force. As the tooth line rises vertically to the gums on the lower jaw and goes deeper into the throat side, it is supported by thicker gums and gums, and the molars grow on the oblique curve of the lower jaw, forming a curve. The main masseter muscle, which is the output of biting, is tied to the side of the lower jaw and continues to the temple. The balanced occlusal position is at the position shown in FIG. 4 that has an oblique angle with the body and that the upper and lower molars touch lightly, and the height of the deepest molar is shown in FIG. The mandibular fossa shown and the position of the mandibular head in Fig. 6 (a) 10 are closely linked, and the masticatory muscles ("Dental Technician Dictionary" Dental Drug Publishing Co., Ltd. 2007 published 318p, 319p) ), Through the membrane that binds the fascia and muscles, leads to the muscular strength of the whole body and keeps the balance of the body structure. The stable position of the lower jaw seems to play a role in maintaining physical balance ("Anatomy Train" Thomas W. Meyers School of Medicine, 2009, 5p, 6p)
大臼歯は、日常生活の中でも常に負荷力を受ける環境にあり、ストレスや咀嚼時などにおいて他の歯より摩耗しやすい位置にある。運動時は、複雑な咀嚼運動とは異なり、奥歯を上下に噛み込む動作が主になり、瞬間的に咬み込む最大負荷力は大きく、奥歯の運動時の傾斜、摩耗、接壊も避けて通れない。下顎の本来の位置での安定と大臼歯のもつ本来の高さと、上下の歯の噛み合う本来の位置を守ることで、重心が安定し、首、肩、背中へ伝わる力の効率の良い分散が可能になり、身体の負担を軽減する事ができる。大臼歯の摩耗や接壊は、大臼歯の高さ不足を引き起こし、隣接歯・大臼歯、小臼歯の高さがその代わりを引き受け不釣り合いな状況を作り出す。 The molar is in an environment that is constantly subjected to a load force in daily life, and is in a position where it is more easily worn than other teeth during stress or chewing. During exercise, unlike complex mastication movements, the main action is to bite the back teeth up and down, and the maximum load force to momentarily bite is large, avoiding inclination, wear and breakage during movement of the back teeth Absent. By maintaining the original position of the lower jaw, the original height of the molars, and the original position where the upper and lower teeth mesh, the center of gravity stabilizes and the power transmitted to the neck, shoulders, and back is efficiently distributed. It becomes possible, and the burden on the body can be reduced. The wear and fracture of the molars causes the height of the molars to be insufficient, and the height of the adjacent teeth, molars, and premolars takes over and creates an unbalanced situation.
本発明は、請求項２に示す形状に依り、下顎の安定を計り、下顎の喉側への移動を防止し、最も奥に位置する大臼歯の本来の噛み合う位置を保持しながら、最小数値で重点的に非日常的な負荷力から摩耗、接壊から保護することを目的している。楔形を利用することで、利用する人の個性に合った型が自動的に形つくられる事になり、その咬合位置が、下顎と下顎頭、上下大臼歯の噛み合う位置、大臼歯の本来の高さの必然性を保持することで、大臼歯の高さ不足や左右の高さ違いを正し、釣り合いのとれた状態で運動機能を発揮できることを可能にした。 In accordance with the shape of the present invention, the present invention measures the stability of the lower jaw, prevents the lower jaw from moving to the throat side, and maintains the original meshing position of the farthest molars with the minimum value. The main purpose is to protect against wear and breakage from extraordinary loading forces. By using the wedge shape, a mold that matches the individuality of the user is automatically formed, and the occlusal position is the position where the mandible and mandibular head, the upper and lower molars mesh, the original height of the molar By maintaining the inevitability, it was possible to correct the insufficient height of the molars and the difference in height between the left and right sides, and to exert motor functions in a balanced state.
挟持部分に繋がる、図５（ア）７の楔形状部分の近傍位置に、図３の１３に示す２０°の角度を持たせることで、大臼歯に沿い易い形状を得、下顎の曲線に沿った角度が、大臼歯に加える高さ数値の増加を抑えることに繋がった。図２の２，３の咬合部分の余分な長さを切り取り、大臼歯の大きさと咬合位置を合わせ、軟化させた咬合部分を最小の力で奥歯の高さを定め咬痕を付け、冷却し、不必要と思われる部分を切り落とし、図５（イ）で、型作りを完了させる。曲線と角度を持つ基本形は、個性に合わせた歯の形状に沿い易く、また、作る工程が少ないのが特徴である。奥歯で咬持するだけの単純な形は、使用時の着脱に手間取らず、誰でも使用可能な形状を持つため（イ）から(二)までの問題解決の目的を果たせたといえる。 By providing a 20 ° angle shown in 13 of FIG. 3 at a position near the wedge-shaped portion of FIG. 5A connected to the sandwiching portion, a shape that is easy to follow along the molar is obtained, and along the curve of the lower jaw This led to the suppression of the increase in the height value applied to the molars. Cut out the extra length of the occlusal portion of 2 and 3 in FIG. 2, match the size of the molar and the occlusal position, set the height of the back teeth with the minimum force on the softened occlusal portion, mark the bite, cool it, Cut off the unnecessary parts and complete the mold making in Fig. 5 (a). The basic shape with curves and angles is easy to follow the shape of the tooth according to individuality, and is characterized by fewer steps to make. It can be said that the simple shape that just holds it with the back teeth can solve the problems (i) to (ii) because it has a shape that anyone can use without taking time to attach and detach it.
本発明は、本来の下顎位置に最小限の高さの保護素材で大臼歯を咬合し、上下大臼歯の噛み合わせを強制することなく、本発明を利用することで釣り合いのとれた噛み合わせ位置を定め、その位置を変えることなく挟持し、非日常的な運動の負荷力から歯を守り、運動時の効率の良い力の発揮と同時に引き起こされる食いしばりから、奥大臼歯の受ける負担を和らげることが可能になった。下顎の釣り合いのとれた位置の噛み合わせの保持は、頭部重心を変えることなく負荷力を支え平均感覚を維持し、本来の身体機能の発揮を阻害しないため、首、肩、腰、膝の負担を軽減する事ができる。また、すでに、奥歯の摩耗の顕著になった年齢の人たちにも、本発明で大臼歯位置に本来の高さを取り戻し、下顎の安定した状態で食いしばることが可能になり、従来では得られなかった運動の負荷力の増加（個体の持つ本来の力）、平均感覚の復活が得られることにも繋った。 The present invention provides a meshing position that is balanced by using the present invention without biting the molars with the protective material of the minimum height at the original lower jaw position and forcing the meshing of the upper and lower molars. And holding the teeth without changing their position, protecting the teeth from the extraordinary exercise load, and relieving the burden received by the back molars from the clenching caused simultaneously with the exertion of efficient force during exercise Became possible. Keeping the lower jaw in a balanced position supports the load without changing the center of gravity of the head, maintains the average sense, and does not hinder the performance of the original body function. The burden can be reduced. In addition, it is possible to restore the original height to the molar position in the present invention and to clench the mandible in a stable state even for those who have already experienced the wear of the back teeth. It also led to an increase in the load of exercise that was not present (the original strength of the individual) and the return of the average sense.
本発明の持つ形状は、上下大臼歯の間で咬合することで、本人の特徴的な歯型と必要な高さを自動的に形作ることが可能である。人は、釣り合いのとれた身体状態を知る感覚を持っており、本来の身体の構造に近づけることで、当人が無意識下でそれを認識し、従来の機能的な姿勢を取り戻すことができるようである。奥歯に取り戻した本来の高さと噛み合う位置は低下した身体機能の回復にも繋がっていくようである。 The shape possessed by the present invention can automatically form the tooth shape characteristic and the required height by engaging the upper and lower molars. The person has a sense of knowing the balanced physical condition, and by approaching the original body structure, the person can recognize it unconsciously and restore the conventional functional posture. It is. It seems that the position that meshes with the original height restored to the back teeth will lead to the recovery of the lowered physical function.
熱可塑性樹脂のポリプロピレンを利用し図１、図２の示す馬蹄形状を基本とし、図中の２、３、を上下大臼歯で咬合部分とする。咬合部分に図５（ア）の矩形と楔形を一体化させた形状と厚みをもたせ、支持体に角度を持たせることで、斜め曲線上にある奥大臼歯にフィットするよう工夫した。弾力性を持つ素材を左右の上下大臼歯に添着、軽く挟持して使用するものである。使う人の独自の歯型に合わせるための工夫から生まれた形状は、繰り返し使う事で正確な型が自動的に作られる特徴をもつ。 The horseshoe shape shown in FIG. 1 and FIG. 2 is basically used using polypropylene of thermoplastic resin, and 2, 3 in the figure are occluded portions with upper and lower molars. The occlusal part has a shape and thickness obtained by integrating the rectangular shape and wedge shape shown in FIG. 5 (a), and the support body is given an angle so that it fits to the back molar on the oblique curve. A material with elasticity is affixed to the left and right upper and lower molars and used by lightly clamping. The shape born from the device to match the user's original tooth pattern has the feature that an accurate mold is automatically created by repeated use.
本発明のマウスピースにおいて、保護素材を上下大臼歯に咬合させる厚みは、開口最大値で割り出すのではなく、閉口時を０として、閉口から開口過程の距離を最小数値に求める。個体のもつ本来の開口最大数値＜咬合時の高さ数値も、最小数値＞咬合時の高さ数値となる場合（人工的摩耗に依る高さ不足）も、咬合位置の不均等をなす。食いしばる上下大臼歯の落下距離を図６（ア）９、１０の間に求め、歯の自然摩耗範囲とされる２ｍｍを加えた高さを、マウスピースの必要な高さの最大値とした。 In the mouthpiece of the present invention, the thickness at which the protective material is engaged with the upper and lower molars is not determined by the maximum value of the opening, but the closing time is set to 0, and the distance of the opening process from the closing is determined to the minimum value. Even when an individual's original maximum opening value <height value at the time of occlusion is also a minimum value> height value at the time of occlusion (insufficient height due to artificial wear), the occlusal position is uneven. The falling distance of the upper and lower molars clinging was determined between FIGS. 6 (a) and 9 and the height obtained by adding 2 mm, which is considered as the natural wear range of the teeth, was taken as the maximum required height of the mouthpiece.
本発明の基準値を図１、の１〜３を、直径７０ｍｍと半径５０ｍｍを持つ半円の支持体の両端に、図２の３、４に厚みを持たせた。拡大した図５（ア）において８、を、１５ｍｍ×１５ｍｍ×４ｍｍの矩形とし、７、を３ｍｍ＋４ｍｍ×１０ｍｍ÷２、３ｍｍ＋１０ｍｍ×１０ｍｍ÷２の楔形を持たせて一体とし、左右の矩形部分を軟化させ、上下左右の大臼歯を咬合し咬み痕を軽くつけ、安定位置の目安とする。図１の１、図２の１、図３の１は上下大臼歯の咬合部を支える支持体で、左右咬合面に繋がり、隣接歯と小臼歯を通り、前歯内側に入る。支持体の持つ角度は高さ調節を自動的に生じさせる為の重要な部分でもある。図５（ア）の示す使用前の形状を、大臼歯の残存数に合わせて、図５（ア）、８の部分の長さと角を切り落とし、使用者に合わせ高さ調節を行ったのが、図５、（イ）であり、使い続けることで変化していく部分である。 The reference values of the present invention are 1 to 3 in FIG. 1, and both ends of a semicircular support having a diameter of 70 mm and a radius of 50 mm are provided, and thicknesses 3 and 4 in FIG. In Fig. 5 (a), 8 is a 15 mm x 15 mm x 4 mm rectangle, 7 is integrated with a 3 mm + 4 mm x 10 mm / 2, 3 mm + 10 mm x 10 mm / 2 wedge shape, and the left and right rectangular parts are softened. The upper, lower, left and right molars are occluded, and the bite mark is lightly applied to provide a stable position. 1 in FIG. 1, 1 in FIG. 2, and 1 in FIG. 3 are supports that support the occlusal portion of the upper and lower molars, are connected to the left and right occlusal surfaces, pass through adjacent teeth and premolars, and enter the front teeth. The angle of the support is also an important part for automatically causing the height adjustment. The shape before use shown in FIG. 5 (a) is adjusted to the number of remaining molars, and the length and corners of the parts of FIG. 5 (a) and 8 are cut off, and the height is adjusted according to the user. FIG. 5B is a part that changes as the user continues to use it.
本発明に基準値を定めても、本発明の特徴である形状が、利用者が下顎を安定させて使い続けるうちに、個体の独自性に合った咬合型を作り出し、基準値から変化していくのが特徴であるため、本発明に課した数値はあくまでも目安数値である。本発明を使い続ける事によって、個体の持つ歯に必要な高さが自動的に作られ、使い続けてもそれ以上変わらない形が生まれる。その型にさらに２ｍｍの高さを載せる事が、使用する個体にとって無理のない適切な高さと形状になる。 Even if the reference value is defined in the present invention, the shape that is a feature of the present invention creates an occlusal shape that matches the individual's uniqueness while the user continues to use the lower jaw stably, and changes from the reference value. Since it is characteristic, the numerical value imposed on the present invention is only a guideline numerical value. By continuing to use the present invention, the height necessary for the teeth of an individual is automatically created, and a shape that does not change any more even if it is used continuously is born. Placing an additional 2 mm height on the mold makes it an appropriate height and shape for the individual to use.
発明は、図５（ア）の示すように、矩形と楔形を併せ持ち、図３の１３に示す位置に角度を持たせ、大臼歯以外の歯に負荷が掛かりにくい形を持つ。最も奥の大臼歯に当る位置の高さを、最低４ｍｍから最高8ｍｍとし、素材を熱可塑性樹脂のポリプロピレンなどを利用し基本形を成し、使用者は、基本形である、図２の２、３の咬合部を湯で軟化させ、大臼歯の高さを前歯の当たらぬ位置に定め、軽く噛み痕をつけて位置を定め、不必要だと思う長さと咬合部の角を落とし、図５（イ）に仕上げる。斜め曲線の構造は大臼歯を上げることと、前歯をあげることが通じているため、下顎の曲線上にある大臼歯の、適正な位置での咬合とその他の歯の接壊を保護することに繋がる。男女の異なる歯型の大きさ、大臼歯の残存数、自然摩耗や人工的摩耗で引き起こされた大臼歯の高さ不足の数値に対応できるよう、図５（ア）８の位置に厚み数値の幅を持たせ対応可能にした。支持体の角度、楔形状、矩形状の３点は、上下大臼歯の咬合面のフィット感を得るための工夫であるが、弾力性のある素材と形状が、本発明の繰り返す使用により、個体に必要な数値と形状を自動的に写し取る仕組みにも繋がった。基本型の咬合位置を誤ると、必要のない位置での咬合となり、奥大臼歯以外での噛み合わせの持続は、奥大臼歯より負荷抵抗力の低いその他の歯茎への負担を増すことに繋がるため、基本形を作る者は下顎運動、顎関節の仕組み、大臼歯の本来の高さの必然を熟知する必要がある。 As shown in FIG. 5A, the invention has both a rectangular shape and a wedge shape, has an angle at a position indicated by 13 in FIG. 3, and has a shape in which it is difficult for a tooth other than a molar tooth to be loaded. The height of the position that hits the deepest molar is set to a minimum of 4 mm to a maximum of 8 mm, and the basic material is formed by using a material such as polypropylene of a thermoplastic resin. Soften the occlusal part with hot water, determine the height of the molars at the position where the front teeth do not touch, determine the position with a slight bite mark, drop the length and the angle of the occlusal part considered unnecessary, Fig. 5 ( B) Finish. Since the oblique curve structure can raise the molars and raise the front teeth, it protects the occlusal position of the molars on the lower jaw curve and the destruction of other teeth. Connected. Figure 5 (A) 8 shows the thickness value so that it can cope with the different tooth types of males and females, the remaining number of molars, and the insufficient height of the molars caused by natural or artificial wear. A width was made available. The angle of the support, the wedge shape, and the rectangular shape are devised to obtain the fit of the occlusal surfaces of the upper and lower molars, but the elastic material and shape can be used by repeating the present invention. It also led to a mechanism for automatically copying the numerical values and shapes necessary for. If the occlusal position of the basic type is mistaken, it will be occluded at a position that is not necessary, and the continued occlusion other than the back molar will increase the burden on other gums that have lower load resistance than the back molar. Therefore, the person who makes the basic shape needs to know the mandibular movement, the mechanism of the temporomandibular joint, and the necessity of the original height of the molar.
本発明の形状のもつ咬合部の厚み数値が、人工的な奥歯の摩耗をきたしている人への対応も可能にし、スポーツ愛好家の利用において、運動能力の発揮と負荷力を軽減する事ができる。失った奥大臼歯の高さ、左右の歯の高さ違いを正すことのできる本発明は歯科治療時の噛み合わせ調節に利用可能な部分もあると思う。 The thickness value of the occlusal part of the shape of the present invention also makes it possible to deal with people who have artificial back teeth wear, and in the use of sports enthusiasts, it can reduce exercise performance and load force it can. I think that the present invention, which can correct the height of the lost back molar and the difference in height between the left and right teeth, can be used to adjust the meshing during dental treatment.
