　ところで、昨今の医療技術の進歩により、人間の寿命は延びてきており、何らの対策をしない場合、生涯にわたり自らの歯を維持することは難しい。そこで、マウスピースを用いることによって、歯を保護することが重要となるが、マウスピースは、個人の歯型を取って作成（オーダーメイド）されるか、標準的な歯列を基準に作成されたのが市販されているのが通常である。前者は高価になり易く、後者は、歯列に合うマウスピースを探し難いという問題がある。 By the way, due to recent advances in medical technology, human lifespans are increasing, and if no measures are taken, it will be difficult to maintain one's own teeth throughout one's life. Therefore, it is important to protect the teeth by using a mouthpiece, but mouthpieces are either made by taking molds of the individual's teeth (custom-made) or are made based on a standard dentition. These are usually commercially available. The former tends to be expensive, and the latter has the problem that it is difficult to find a mouthpiece that fits the alignment of the teeth.
　そこで、本発明は、歯型を取って作成しなくても、生涯継続して使用することができるマウスピースを提供することをその目的とする。 Therefore, an object of the present invention is to provide a mouthpiece that can be used continuously for a lifetime without the need to take impressions of the teeth.

　本発明のマウスピースによれば、基部から上顎側に延設され、装着時に、上顎の中切歯と上唇の間に位置し、上顎の少なくとも中切歯の唇側面が当接し得るように構成された上外壁と、基部から下顎側に延設され、装着時に、下顎の中切歯と舌の間に位置し、下顎の少なくとも中切歯の舌側面が当接し得るように構成された下内壁を具えているから、マウスピースを装着した状態で仰向けとなり、顎に重力による垂下方向の力がかかったとき、下顎の少なくとも中切歯がマウスピースを介して上顎の少なくとも中切歯に引っ掛かり、仰向け時の顎の垂下方向の移動を防止することができる。また、下内壁から基部の内側、且つ、下顎方向に延出し、中央に溝を有することによりＵ字形をなす舌置部を具えるので、舌置部に舌が載ることにより、舌尖が硬口蓋に当たり易くなり、低位舌や鼾の予防及び改善に繋がる。また、上顎及び下顎の中切歯から第二大臼歯の少なくとも一部までに対応するＵ字形の基部及び下内壁が、第二小臼歯と第一大臼歯の間と第一大臼歯と第二大臼歯の間のそれぞれに対応する位置の少なくとも一部に第一切断案内部及び第二切断案内部を具え、舌置部が第一切断案内部及び第二切断案内部とそれぞれ対応する第一舌置部切断案内部及び第二舌置部切断案内部を具えているので、マウスピースを第一・第二切断案内部と第一・第二舌置部切断案内部に沿って、第二小臼歯と第一大臼歯の間と第一大臼歯と第二大臼歯の間のそれぞれに対応する位置で切断し易い。これにより、中切歯から第二小臼歯までの乳歯が生え揃っているときから、第二大臼歯が生える前の状態と、中切歯から第二大臼歯の永久歯が生え揃うときまで、同型のマウスピースを生涯継続して使用することができる。 According to the mouthpiece of the present invention, the mouthpiece extends from the base to the maxillary side, is positioned between the central incisors of the maxilla and the upper lip when worn, and is configured such that at least the labial side of the central incisors of the maxilla can come into contact. The upper outer wall extends from the base to the mandibular side and is located between the central incisors of the mandible and the tongue when worn, and is configured such that at least the lingual side of the central incisors of the mandible can come into contact. Because it has an inner wall, when you lie on your back with the mouthpiece on and a downward force due to gravity is applied to your jaw, at least the central incisors of the lower jaw will catch on at least the central incisors of the upper jaw through the mouthpiece. , it is possible to prevent the jaw from moving in the downward direction when lying on the back. In addition, it has a U-shaped tongue rest that extends from the lower inner wall to the inside of the base and in the direction of the mandible and has a groove in the center, so when the tongue rests on the tongue rest, the tip of the tongue touches the hard palate. This will help prevent and improve low tongue and snoring. In addition, the U-shaped base and lower inner wall corresponding to at least a portion of the upper and lower central incisors to the second molars are formed between the second premolars and the first molars and between the first molars and the second molars. A first cutting guide and a second cutting guide are provided at least in part at corresponding positions between the molar teeth, and the tongue resting part is provided with a first cutting guide and a second cutting guide corresponding to the first cutting guide and the second cutting guide, respectively. Since the tongue rest cutting guide part and the second tongue rest cutting guide part are provided, the mouthpiece can be moved along the first and second cutting guide parts and the first and second tongue rest cutting guide parts. It is easy to cut at positions corresponding to between premolars and first molars and between first molars and second molars. This ensures that the condition is the same from when all the baby teeth from the central incisors to the second premolars have erupted, to before the second molars have erupted, to when the permanent teeth from the central incisors to the second molars have erupted. The mouthpiece can be used continuously for a lifetime.
　これにより、本発明のマウスピースの使用者は、以下のような利益を得られる。まず、比較的低コストで製造可能な同型のマウスピースを生涯継続して使用することができるので、使用者の歯列に応じたマウスピースをオーダーメイドせずに済み、経済的である。次に、仰向け時の顎の垂下方向の移動を防止することができることにより、頭蓋骨、特に下顎窩に対する下顎頭の位置がずれることを防止することができる。これにより、顎関節症の発症や、下顎頭が耳孔方向に移動して耳孔や下顎枝部、これらの周辺の神経を押し潰すことによって発症する難聴その他の症状の発症を防止することができる。また、マウスピースを装着して就寝することにより、鼻呼吸優位となり、口内の乾燥を防ぎ、菌やウィルスの増殖を防ぐことができるとともに、いびき防止にも繋がる。特に、中切歯から第二小臼歯までの乳歯が生え揃っている幼児の段階においては、就寝時の鼻呼吸優位の状態が、上顎洞の成長を促進させ得る。ところで、上顎洞の未発達は、切端咬合や反対咬合（受け口）の一因と考えられるので、本発明のマウスピースを幼児の頃から使用し続けることにより、切端咬合や反対咬合の発症を抑制できる。また、歯の摩耗は、口が窄むことやほうれい線を含む口周りのしわ等の口元の老化の一因と考えられる。そこで、上顎と下顎の歯の間にマウスピースが介在することにより、歯同士の摩擦による歯の摩耗を防ぐことができるので、口元の老化を抑制することもできる。 As a result, the user of the mouthpiece of the present invention can obtain the following benefits. First, since the same type of mouthpiece can be manufactured at a relatively low cost and can be used continuously for a lifetime, there is no need to custom-make a mouthpiece according to the user's dentition, which is economical. Next, by preventing the jaw from moving in the downward direction when lying on the back, it is possible to prevent the position of the mandibular condyle from shifting relative to the skull, particularly the mandibular fossa. This can prevent the onset of temporomandibular joint disorder and the onset of hearing loss and other symptoms caused by the mandibular condyle moving toward the ear canal and crushing the ear canal, mandibular ramus, and the surrounding nerves. In addition, by wearing a mouthpiece while sleeping, you will have an advantage in breathing through your nose, which will prevent your mouth from drying out, prevent the growth of bacteria and viruses, and also help prevent snoring. In particular, at the stage of infants when all the baby teeth from the central incisors to the second premolars have erupted, the state of dominant nasal breathing during sleep can promote the growth of the maxillary sinus. By the way, underdevelopment of the maxillary sinus is thought to be a cause of incisal occlusion and reverse occlusion (receptacle), so by continuing to use the mouthpiece of the present invention from childhood, the development of incisal occlusion and reverse occlusion can be suppressed. can. In addition, tooth wear is thought to be a contributing factor to the aging of the mouth, such as narrowing of the mouth and wrinkles around the mouth, including nasolabial folds. Therefore, by interposing a mouthpiece between the teeth of the upper jaw and the lower jaw, it is possible to prevent tooth wear due to friction between the teeth, and thus it is also possible to suppress aging of the mouth area.
　また、舌置部の厚みが基部の端部又は第一大臼歯に対応する位置から中切歯側に向けて次第に厚くなっている構成とすれば、舌尖が硬口蓋にさらに当たり易いマウスピースとすることができる。 In addition, if the thickness of the tongue rest gradually increases from the end of the base or the position corresponding to the first molar toward the central incisors, the tongue tip can more easily contact the hard palate. can do.
　また、舌置部の溝が基部の端部方向に拡開している構成、或いは、第一舌置部切断案内部及び／又は第二舌置部切断案内部が中切歯方向に傾斜している構成とし、第一舌置部切断案内部及び／又は第二舌置部切断案内部に沿って切断し易くすれば、オトガイ舌筋が干渉し難いマウスピースとすることができる。 In addition, the groove of the tongue rest may be expanded toward the end of the base, or the first tongue rest cutting guide and/or the second tongue rest cutting guide may be inclined toward the central incisor. If the mouthpiece is configured such that it is easy to cut along the first tongue rest section cutting guide section and/or the second tongue rest section cutting guide section, it is possible to obtain a mouthpiece in which the genioglossus muscle is less likely to interfere.
　また、舌置部が基部に沿うＵ字状切断案内部をさらに具える構成とし、Ｕ字状切断案内部に沿って切断し易くすれば、骨隆起等に干渉し難いマウスピースとすることができる。 Furthermore, if the tongue rest further includes a U-shaped cutting guide along the base, and the tongue rest is made easier to cut along the U-shaped cutting guide, the mouthpiece can be made less likely to interfere with bone prominences, etc. can.
　また、上外壁、上内壁、及び下外壁が基部の端部又は第一大臼歯に対応する位置まで形成されている構成とすれば、上外壁、上内壁、又は下外壁に使用者の各歯が沿うことになり、乱杭歯を防止することができ、口内でマウスピースの位置がずれることを防止することもでき、使用者が横向きに寝た場合にも、顎の垂下方向の移動を防止することができる。 In addition, if the upper outer wall, upper inner wall, and lower outer wall are formed up to the end of the base or the position corresponding to the first molar, each of the user's teeth may be attached to the upper outer wall, upper inner wall, or lower outer wall. This prevents the teeth from becoming misaligned, prevents the mouthpiece from shifting in the mouth, and prevents the jaw from moving in the drooping direction even when the user sleeps on his or her side. can do.
　また、上外壁が、基部のＵ字に沿う上外壁上部切断案内部をさらに具える構成とすれば、上外壁の上部を上外壁上部切断案内部に沿って切断し易いので、子供や女性など、口内が比較的小さい使用者であっても装着し易いマウスピースとすることができる。 In addition, if the upper outer wall is configured to further include an upper outer wall upper cutting guide part along the U-shape of the base, it is easier to cut the upper part of the upper outer wall along the upper outer wall upper cutting guide part, so that children, women, etc. The mouthpiece can be easily worn even by a user with a relatively small mouth.

　図１～４は、本発明の参考例のマウスピース１０を示している。本発明の舌置部４０（後述する。）以外の構成は、マウスピース１０と同様であるため、まず、マウスピース１０について説明する。マウスピース１０は、歯列、具体的には、人体の上顎及び下顎の中切歯から第二大臼歯の少なくとも一部までの歯列の湾曲形状に対応したＵ字形の基部１２を具えている。マウスピース１０は、平面視で左右対称の形状を具えている。 1 to 4 show a mouthpiece 10 as a reference example of the present invention. The configuration of the present invention other than the tongue rest 40 (described later) is the same as the mouthpiece 10, so the mouthpiece 10 will be described first. The mouthpiece 10 includes a U-shaped base 12 that corresponds to the curved shape of the tooth row, specifically, the tooth row from the central incisors to at least a portion of the second molars of the upper and lower jaws of the human body. . The mouthpiece 10 has a symmetrical shape when viewed from above.
　基部１２は、上顎側に延設され、装着時に、上顎の中切歯と上唇の間に位置し、上顎の少なくとも中切歯の唇側面が当接し得るように構成された上外壁２２と、装着時に、上顎の中切歯から第二大臼歯と硬口蓋の間に位置するように構成され、基部１２の中切歯から第一大臼歯に対応する位置まで形成された上内壁２４を具えている。上外壁２２及び上内壁２４は、基部１２の端部に対応する位置までの任意の範囲で形成することができる（図３も参照。）。 The base 12 has an upper outer wall 22 that extends toward the maxilla, is positioned between the central incisors of the maxilla and the upper lip when worn, and is configured such that at least the labial side of the central incisors of the maxilla can come into contact with it; The upper inner wall 24 is configured to be located between the central incisors of the upper jaw, the second molars, and the hard palate when worn, and is formed from the central incisors of the base 12 to a position corresponding to the first molars. It is growing. The upper outer wall 22 and the upper inner wall 24 can be formed in any range up to a position corresponding to the end of the base 12 (see also FIG. 3).
　図２に示すように、基部１２は、下顎側に延設され、装着時に、下顎の中切歯と舌の間に位置し、下顎の少なくとも中切歯の舌側面が当接し得るように構成された下内壁３４と、装着時に、下顎の中切歯から第二大臼歯と下唇の間に位置するように構成され、基部１２の中切歯から端部に対応する位置まで形成された下外壁３２を具えている。下内壁３４は、基部１２の端部又は第一大臼歯に対応する位置まで形成され、下外壁３２は、基部１２の端部に対応する位置までの任意の範囲で形成することができる（図４も参照。）。 As shown in FIG. 2, the base 12 is configured to extend toward the mandible and be located between the central incisors of the mandible and the tongue when worn, so that at least the lingual side of the central incisors of the mandible can come into contact. The lower inner wall 34 is configured to be located between the central incisor of the lower jaw, the second molar, and the lower lip when worn, and is formed from the central incisor of the base 12 to a position corresponding to the end. It has a lower outer wall 32. The lower inner wall 34 can be formed to a position corresponding to the end of the base 12 or the first molar, and the lower outer wall 32 can be formed to any range up to a position corresponding to the end of the base 12 (see FIG. (See also 4).
　基部１２、上外壁２２、上内壁２４，下外壁３２，及び下内壁３４は、公知の樹脂材料で構成されている。基部１２、上外壁２２、上内壁２４，下外壁３２，及び下内壁３４の大きさ、厚み、及び形状は、任意に設定することができ、例えば、性別ごとの歯列の標準モデルや口腔内の標準的な大きさを基準にして設定すればよい。 The base 12, the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, and the lower inner wall 34 are made of a known resin material. The size, thickness, and shape of the base 12, upper outer wall 22, upper inner wall 24, lower outer wall 32, and lower inner wall 34 can be set arbitrarily. It can be set based on the standard size of .
　このように、マウスピース１０は、基部１２から上顎側に延設され、装着時に、上顎の中切歯と上唇の間に位置し、上顎の少なくとも中切歯の唇側面が当接し得るように構成された上外壁２２と、基部１２から下顎側に延設され、装着時に、下顎の中切歯と舌の間に位置し、下顎の少なくとも中切歯の舌側面が当接し得るように構成された下内壁３４を具えているから、使用者がマウスピース１０を装着した状態で仰向けとなり、使用者の顎に重力による垂下方向の力がかかったとき、下顎の少なくとも中切歯がマウスピース１０を介して上顎の少なくとも中切歯に引っ掛かり、仰向け時の顎の垂下方向の移動を防止することができる。 In this way, the mouthpiece 10 extends from the base 12 toward the upper jaw, and when worn, is positioned between the central incisors of the upper jaw and the upper lip, so that at least the labial side of the central incisors of the upper jaw can come into contact with the mouthpiece 10. The upper outer wall 22 is configured to extend from the base 12 toward the lower jaw side, and is configured to be located between the central incisors of the lower jaw and the tongue when worn, so that at least the lingual side of the central incisors of the lower jaw can come into contact. Since the lower inner wall 34 is provided with a lower inner wall 34, when the user lies on his back wearing the mouthpiece 10 and a downward force due to gravity is applied to the user's jaw, at least the central incisors of the lower jaw are exposed to the mouthpiece. 10 to at least the central incisors of the upper jaw, and can prevent the jaw from moving in the downward direction when lying on the back.
　また、上外壁２２、上内壁２４，下外壁３２、及び下内壁３４が基部１２の端部又は第一大臼歯に対応する位置まで形成されている構成とすれば、上外壁２２、上内壁２４、下外壁３２、又は下内壁３４に使用者の各歯が沿うことになり、乱杭歯を防止することができ、口内におけるマウスピースの位置がずれることを防止することもできる。 Furthermore, if the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, and the lower inner wall 34 are formed up to a position corresponding to the end of the base 12 or the first molar, the upper outer wall 22, the upper inner wall 24 , the lower outer wall 32 or the lower inner wall 34, each of the user's teeth can be prevented from becoming uneven, and the position of the mouthpiece in the mouth can also be prevented from shifting.
　また、基部１２の端部又は第一大臼歯に対応する位置まで形成された上外壁２２又は上内壁２４と、基部１２の端部又は第一大臼歯に対応する位置まで形成された下外壁３２又は下内壁３４を設けることにより、使用者が横向きに寝た場合にも、使用者の顎に重力による垂下方向の力がかかったとき、下顎のいずれかの歯がマウスピース１０を介して上顎のいずれかの歯に引っ掛かり、顎の垂下方向の移動を防止することができる。 Also, an upper outer wall 22 or an upper inner wall 24 formed up to a position corresponding to the end of the base 12 or the first molar, and a lower outer wall 32 formed up to a position corresponding to the end of the base 12 or the first molar. Alternatively, by providing the lower inner wall 34, even when the user sleeps on his/her side, when a downward force due to gravity is applied to the user's jaw, any of the teeth in the lower jaw can be moved through the mouthpiece 10 to the upper jaw. It can catch on any of the teeth and prevent the jaw from moving in the downward direction.
　図１に示すように、基部１２の上顎面には、第一切断案内部２６ａ，２６ｂと第二切断案内部２８ａ，２８ｂが設けられている。第一切断案内部２６ａ，２６ｂは、基部１２の第二小臼歯と第一大臼歯の間に対応する位置の少なくとも一部に、そして、第二切断案内部２８ａ，２８ｂは、第一大臼歯と第二大臼歯の間に対応する位置の少なくとも一部に設けられていればよい。 As shown in FIG. 1, the maxillary surface of the base 12 is provided with first cutting guides 26a, 26b and second cutting guides 28a, 28b. The first cutting guides 26a, 26b are attached to at least a portion of the base 12 at a position corresponding to between the second premolar and the first molar, and the second cutting guides 28a, 28b are attached to the first molar. It suffices if it is provided at least in part at a position corresponding to between the first molar and the second molar.
　図２に示すように、基部１２は、その下顎面にも、第一切断案内部３６ａ，３６ｂと第二切断案内部３８ａ，３８ｂが設けられている。下顎面に設けられている第一切断案内部３６ａ，３６ｂと第二切断案内部３８ａ，３８ｂの構成は、上顎面に設けられている第一切断案内部２６ａ，２６ｂと第二切断案内部２８ａ，２８ｂの構成と同様である。なお、第一切断案内部と第二切断案内部は、基部１２の上顎面又は下顎面のいずれかに設けた構成とすることもできる。 As shown in FIG. 2, the base 12 is also provided with first cutting guide parts 36a, 36b and second cutting guide parts 38a, 38b on its mandibular surface. The configuration of the first cutting guide parts 36a, 36b and the second cutting guide parts 38a, 38b provided on the mandibular surface is the same as the first cutting guide parts 26a, 26b and the second cutting guide part 28a provided on the maxillary surface. , 28b. Note that the first cutting guide part and the second cutting guide part may be provided on either the maxillary surface or the mandibular surface of the base 12.
　マウスピース１０の場合、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂ及び第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂは、凹溝である。第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂ及び第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂは、凹溝の他、突条、突起又は孔や穴（連続して設けられているものを含む。）、或いは、印刷した線や破線であってもよい。また、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂ及び第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂは、直線状であっても曲線状であってもよい。 In the case of the mouthpiece 10, the first cutting guides 26a, 26b, 36a, 36b and the second cutting guides 28a, 28b, 38a, 38b are grooves. The first cutting guide portions 26a, 26b, 36a, 36b and the second cutting guide portions 28a, 28b, 38a, 38b include grooves, protrusions, protrusions, holes, and holes (continuously provided ones). ), or may be a printed line or broken line. Further, the first cutting guide portions 26a, 26b, 36a, 36b and the second cutting guide portions 28a, 28b, 38a, 38b may be linear or curved.
　このように、マウスピース１０には、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂが設けられているから、マウスピース１０を第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂに沿って、第二小臼歯と第一大臼歯の間に対応する位置で切断し易い。マウスピース１０を第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂに沿って切断して使用するのに好適な時期は、使用者の第一大臼歯が生え始めた５才頃からである。これにより、中切歯から第二小臼歯までの乳歯が生え揃っているときから、中切歯から第二大臼歯の永久歯が生え揃うときまで、同型のマウスピースを生涯継続して使用することができる。 As described above, since the mouthpiece 10 is provided with the first cutting guide parts 26a, 26b, 36a, and 36b, the mouthpiece 10 can be moved along the first cutting guide parts 26a, 26b, 36a, and 36b. It is easy to cut at the corresponding position between the second premolar and first molar. A suitable time to use the mouthpiece 10 by cutting it along the first cutting guide portions 26a, 26b, 36a, and 36b is from around the age of five, when the user's first molars begin to grow. This allows you to continue using the same type of mouthpiece throughout your life, from when all the baby teeth from the central incisors to the second premolars have erupted, until all the permanent teeth from the central incisors to the second molars have erupted. I can do it.
　また、マウスピース１０に第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂが設けられている構成とすれば、マウスピース１０を第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂに沿って、第一大臼歯と第二大臼歯の間に対応する位置で切断し易い。これにより、第二大臼歯が生える前の状態であっても使用し易いマウスピース１０とすることができる。マウスピース１０を第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂに沿って切断して使用するのに好適な時期は、使用者が７才～１０才くらいのときである。 Furthermore, if the mouthpiece 10 is provided with the second cutting guide parts 28a, 28b, 38a, 38b, the mouthpiece 10 can be moved along the second cutting guide parts 28a, 28b, 38a, 38b. It is easy to cut at the corresponding position between the molar and second molar. Thereby, the mouthpiece 10 can be made easy to use even before the second molars have erupted. A suitable time to use the mouthpiece 10 by cutting it along the second cutting guides 28a, 28b, 38a, and 38b is when the user is about 7 to 10 years old.
　ここで、上外壁２２、上内壁２４，下外壁３２，又は下内壁３４が基部１２の中切歯から第一大臼歯に対応する位置まで形成されている場合、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂは、上外壁２２、上内壁２４，下外壁３２，又は下内壁３４の内側面又は外側面に設けられていてもよい。 Here, if the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34 is formed from the central incisor of the base 12 to the position corresponding to the first molar, the first cutting guide portions 26a, 26b , 36a, 36b may be provided on the inner or outer surface of the upper outer wall 22, the upper inner wall 24, the lower outer wall 32, or the lower inner wall 34.

　図５は、本発明の第一実施形態のマウスピース１０ａを示している。マウスピース１０と同様の構成を具える部分は、マウスピース１０と同じ符号を付している。マウスピース１０ａは、舌置部４０を具える。舌置部４０は、図６，７，９にも示されているように、基部１２の端部又は第一大臼歯に対応する位置まで形成されている下内壁３４から基部１２のＵ字の内側、且つ、下顎方向に延出するように設けられている。ここで、舌置部４０は、中央に溝４２（図５，１０も参照。）を有するように形成されており、基部１２と同方向のＵ字形をなしている。 FIG. 5 shows a mouthpiece 10a according to the first embodiment of the present invention. Portions having the same configuration as the mouthpiece 10 are given the same reference numerals as the mouthpiece 10. The mouthpiece 10a includes a tongue rest 40. As shown in FIGS. 6, 7, and 9, the tongue rest 40 extends from the lower inner wall 34 of the base 12 to a position corresponding to the end of the base 12 or the first molar. It is provided so as to extend inward and toward the lower jaw. Here, the tongue rest part 40 is formed to have a groove 42 (see also FIGS. 5 and 10) in the center, and is U-shaped in the same direction as the base part 12.
　また、図５に示されているように、舌置部４０には、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂに対応する第一舌置部切断案内部４６ａ，４６ｂと、第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂに対応する第二舌置部切断案内部４８ａ，４８ｂが形成されている。第一舌置部切断案内部４６ａ，４６ｂと第二舌置部切断案内部４８ａ，４８ｂは、第一切断案内部２６ａ，２６ｂ，３６ａ，３６ｂ及び第二切断案内部２８ａ，２８ｂ，３８ａ，３８ｂとそれぞれ連続するように設けることができる（図６，８参照。）。また、第一舌置部切断案内部４６ａ，４６ｂと第二舌置部切断案内部４８ａ，４８ｂは、図１０に示すように、底面側に設けることもできる。 Further, as shown in FIG. 5, the tongue rest part 40 includes first tongue rest cutting guide parts 46a, 46b corresponding to the first cutting guide parts 26a, 26b, 36a, 36b, and a second cutting guide part 46a, 46b. Second tongue rest cutting guide portions 48a, 48b are formed corresponding to the guide portions 28a, 28b, 38a, 38b. The first tongue rest cutting guide parts 46a, 46b and the second tongue rest cutting guide parts 48a, 48b are the first cutting guide parts 26a, 26b, 36a, 36b and the second cutting guide parts 28a, 28b, 38a, 38b. (See FIGS. 6 and 8.) Further, the first tongue rest cutting guide parts 46a, 46b and the second tongue rest cutting guide parts 48a, 48b can also be provided on the bottom side, as shown in FIG.
　上述したように、マウスピース１０ａは、舌置部４０を具えるので、舌置部４０に使用者の舌が載ることにより、その舌尖が硬口蓋に当たり易くなり、低位舌や鼾の予防及び改善に繋げることができる。このとき、舌置部４０は溝４２を具えるので、オトガイ舌筋が干渉し難い。また、舌置部４０は第一舌置部切断案内部４６ａ，４６ｂと第二舌置部切断案内部４８ａ，４８ｂを具えているので、マウスピース１０ａを第一・第二切断案内部２６ａ，２６ｂ，３６ａ，３６ｂ，２８ａ，２８ｂ，３８ａ，３８ｂと第一・第二舌置部切断案内部４６ａ，４６ｂ，４８ａ，４８ｂに沿って、第二小臼歯と第一大臼歯の間と第一大臼歯と第二大臼歯の間のそれぞれに対応する位置で切断し易い。これにより、中切歯から第二小臼歯までの乳歯が生え揃っているときから、第二大臼歯が生える前の状態と、中切歯から第二大臼歯の永久歯が生え揃うときまで、同型のマウスピース１０ａを生涯継続して使用することができる。 As described above, since the mouthpiece 10a includes the tongue rest 40, when the user's tongue rests on the tongue rest 40, the tip of the tongue easily hits the hard palate, thereby preventing and improving a low tongue and snoring. can be connected to. At this time, since the tongue rest part 40 is provided with the groove 42, the genioglossus muscle is unlikely to interfere with it. Moreover, since the tongue rest part 40 includes the first tongue rest cutting guide parts 46a, 46b and the second tongue rest cutting guide parts 48a, 48b, the mouthpiece 10a can be connected to the first and second cutting guide parts 26a, 48b. 26b, 36a, 36b, 28a, 28b, 38a, 38b and the first and second tongue rest cutting guide parts 46a, 46b, 48a, 48b, between the second premolar and the first molar and the first Easy to cut at positions corresponding to the areas between the molars and second molars. This ensures that the condition is the same from when all the baby teeth from the central incisors to the second premolars have erupted, to before the second molars have erupted, to when the permanent teeth from the central incisors to the second molars have erupted. The mouthpiece 10a can be used continuously for a lifetime.
　ここで、舌置部４０は、その厚みが基部１２の端部又は第一大臼歯に対応する位置から中切歯側に向けて次第に厚くなっている構成とすることができる（図６，７，９参照。）。本構成とすることにより、舌尖が硬口蓋にさらに当たり易いマウスピース１０ａとすることができる。 Here, the tongue rest part 40 can be configured such that its thickness gradually increases from the end of the base part 12 or the position corresponding to the first molar toward the central incisor (Figs. 6 and 7). , 9). With this configuration, the mouthpiece 10a can be made such that the tip of the tongue contacts the hard palate more easily.
　また、図５，１０に示すように、溝４２が基部１２の端部方向に拡開している構成、或いは、第一舌置部切断案内部４６ａ，４６ｂ及び／又は第二舌置部切断案内部４８ａ，４８ｂが中切歯方向に傾斜している構成とし、第一舌置部切断案内部４６ａ，４６ｂ及び／又は第二舌置部切断案内部４８ａ，４８ｂに沿って切断し易くすれば、オトガイ舌筋がさらに干渉し難いマウスピースとすることができる。 In addition, as shown in FIGS. 5 and 10, the groove 42 may be expanded toward the end of the base 12, or the first tongue rest cutting guide 46a, 46b and/or the second tongue rest cutting guide may be The guide parts 48a, 48b are configured to be inclined toward the central incisors, making it easier to cut along the first tongue rest cutting guide parts 46a, 46b and/or the second tongue rest cutting guide parts 48a, 48b. For example, it is possible to create a mouthpiece with which the genioglossus muscle is less likely to interfere.
　マウスピース１０ａは、図７，８に示すように、上外壁２２に基部１２のＵ字に沿う上外壁上部切断案内部２２ａが形成されている。上外壁上部切断案内部２２ａは、上外壁上部切断案内部２２ａより上部の範囲が中切歯方向に向かうにつれて大きくなるように形成することができる。上外壁上部切断案内部２２ａを具える構成とすれば、上外壁２２の上部を上外壁上部切断案内部２２ａに沿って切断し易いので、子供や女性など、口内が比較的小さい使用者であっても装着し易いマウスピース１０ａとすることができる。 As shown in FIGS. 7 and 8, the mouthpiece 10a has an upper outer wall upper cutting guide portion 22a formed on the upper outer wall 22 along the U-shape of the base 12. The upper outer wall upper cutting guide part 22a can be formed such that the range above the upper outer wall upper cutting guide part 22a becomes larger toward the central incisor. If the configuration includes the upper outer wall upper cutting guide part 22a, it is easy to cut the upper part of the upper outer wall 22 along the upper outer wall upper cutting guide part 22a, so it is easy to cut the upper part of the upper outer wall 22, so it is easy to cut the upper part of the upper outer wall 22. The mouthpiece 10a can be easily worn even when the user is wearing the mouthpiece.
　図１１は、本発明の第二実施形態のマウスピース１０ｂを示している。マウスピース１０ｂの基本的な構成は、マウスピース１０ａと同じであるため、異なる点について以下に説明する。マスピース１０ｂは、舌置部４０に基部１２（図５，１０参照。）に沿うＵ字状切断案内部４４を具えている。図示しての説明は省略するが、Ｕ字状切断案内部４４は、底面側に設けることもできる。Ｕ字状切断案内部４４を具える構成とすれば、舌置部４０をＵ字状切断案内部４４に沿って切断し易いので、骨隆起等に干渉し難いマウスピース１０ｂとすることができる。 FIG. 11 shows a mouthpiece 10b according to a second embodiment of the present invention. The basic configuration of mouthpiece 10b is the same as mouthpiece 10a, so the differences will be explained below. The mass piece 10b includes a U-shaped cutting guide 44 on the tongue rest 40 along the base 12 (see FIGS. 5 and 10). Although illustration and explanation are omitted, the U-shaped cutting guide portion 44 can also be provided on the bottom side. If the configuration includes the U-shaped cutting guide part 44, the tongue rest part 40 can be easily cut along the U-shaped cutting guide part 44, so that the mouthpiece 10b can be made that is unlikely to interfere with bone prominences or the like. .
　上記に説明したマウスピース１０ａ，１０ｂの場合、第一舌置部切断案内部４６ａ，４６ｂ、第二舌置部切断案内部４８ａ，４８ｂ、及びＵ字状切断案内部４４は、凹溝である。これらは凹溝の他、突条、突起又は孔や穴（連続して設けられているものを含む。）、或いは、印刷した線や破線であってもよい。また、第一舌置部切断案内部４６ａ，４６ｂ及び第二舌置部切断案内部４８ａ，４８ｂは、直線状であっても曲線状であってもよい。 In the case of the mouthpieces 10a and 10b described above, the first tongue rest cutting guide parts 46a and 46b, the second tongue rest cutting guide parts 48a and 48b, and the U-shaped cutting guide part 44 are concave grooves. . These may be grooves, protrusions, protrusions, holes (including those provided continuously), or printed lines or broken lines. Moreover, the first tongue rest cutting guide parts 46a, 46b and the second tongue rest cutting guide parts 48a, 48b may be linear or curved.
　本発明のマウスピース１０ａ，１０ｂの使用者は、以下のような利益を得ることができる。まず、比較的低コストで製造可能な同型のマウスピース１０ａ，１０ｂを生涯継続して使用することができるので、使用者の歯列に応じたマウスピースをオーダーメイドせずに済み、経済的である。次に、仰向け時の顎の垂下方向の移動を防止することができることにより、頭蓋骨、特に下顎窩に対する下顎頭の位置がずれることを防止することができる。これにより、顎関節症の発症や、下顎頭が耳孔方向に移動して耳孔や下顎枝部、これらの周辺の神経を押し潰すことによって発症する難聴その他の症状の発症を防止することができる。また、マウスピース１０ａ，１０ｂを装着して就寝することにより、鼻呼吸優位となり、口内の乾燥を防ぎ、菌やウィルスの増殖を防ぐことができるとともに、いびき防止にも繋がる。特に、中切歯から第二小臼歯までの乳歯が生え揃っている幼児の段階においては、就寝時の鼻呼吸優位の状態が、上顎洞の成長を促進させ得る。上顎洞の未発達は、切端咬合や反対咬合（受け口）の一因と考えられるので、マウスピース１０ａ，１０ｂを幼児の頃から使用し続けることにより、切端咬合や反対咬合の発症を抑制できる。また、歯の摩耗は、口が窄むことやほうれい線を含む口周りのしわ等の口元の老化の一因と考えられる。そこで、上顎と下顎の歯の間にマウスピースが介在することにより、歯同士の摩擦による歯の摩耗を防ぐことができるので、口元の老化を抑制することもできる。 Users of the mouthpieces 10a, 10b of the present invention can obtain the following benefits. First, since the mouthpieces 10a and 10b of the same type can be manufactured at a relatively low cost and can be used continuously for a lifetime, there is no need to custom-make a mouthpiece according to the user's dentition, which is economical. be. Next, by preventing the jaw from moving in the downward direction when lying on the back, it is possible to prevent the position of the mandibular condyle from shifting relative to the skull, particularly the mandibular fossa. This can prevent the onset of temporomandibular joint disorder and the onset of hearing loss and other symptoms caused by the mandibular condyle moving toward the ear canal and crushing the ear canal, mandibular ramus, and the surrounding nerves. In addition, by wearing the mouthpieces 10a and 10b while sleeping, breathing through the nose becomes advantageous, preventing dryness in the mouth, preventing the growth of bacteria and viruses, and also preventing snoring. In particular, at the stage of infants when all the baby teeth from the central incisors to the second premolars have erupted, the state of dominant nasal breathing during sleep can promote the growth of the maxillary sinus. Underdevelopment of the maxillary sinus is considered to be a cause of incisal occlusion and reverse occlusion (socket), so by continuing to use the mouthpieces 10a and 10b from childhood, the development of incisal occlusion and reverse occlusion can be suppressed. In addition, tooth wear is thought to be a contributing factor to the aging of the mouth, such as narrowing of the mouth and wrinkles around the mouth, including nasolabial folds. Therefore, by interposing a mouthpiece between the teeth of the upper jaw and the lower jaw, it is possible to prevent tooth wear due to friction between the teeth, and thus it is also possible to suppress aging of the mouth area.
　以上に説明したとおり、本発明によれば、歯型を取って作成しなくても、生涯継続して使用することができるマウスピースを提供することができる。 As explained above, according to the present invention, it is possible to provide a mouthpiece that can be used continuously for a lifetime without the need to take impressions of teeth.
