Upon using, the connection part (8) is folded and then the protector is mounted. Thus, the individual teeth in the maxillary dentition are coated by the maxillary dentition-coating part (10) while the individual teeth in the mandibular dentition are coated by the mandibular dentition-coating part (11), thereby surely preventing the teeth from damage.

Description

歯牙保護装置Tooth protector
 本発明は、気管内挿管を伴う全身麻酔などの医療行為を行う際や格闘技やその他の激しいスポーツ競技などにおいて、患者や競技者などの使用者の歯牙損傷を防止するために用いる歯牙保護装置に関する。 The present invention relates to a tooth protection device used to prevent tooth damage of a user such as a patient or a competitor when performing a medical act such as general anesthesia with endotracheal intubation or in martial arts or other intense sports competitions. .
 全身麻酔などの医療行為を行う場合に、特殊な鍬の如き形状を有した金属製の喉頭鏡と呼ばれる器具が患者の喉に挿入され、続いて麻酔ガスを患者の肺に送り込むための気管内挿管が行われている。例えば、医療行為者が患者の口を指と喉頭鏡の如き器具で大きく開けてチューブを挿入する場合では、器具や指、チューブなどが患者の歯に接触し、その接触が原因で歯が抜けたり、折れたりする所謂歯牙損傷が発生することがある。折れた歯が万一胃や肺などに入り込んだ場合には、所要の摘出手術などが必要になることもあり、医療の現場では大きな問題となっている。 When performing medical procedures such as general anesthesia, a device called a metal laryngoscope with a special spider-like shape is inserted into the patient's throat, followed by the endotrachea for delivering anesthetic gas into the patient's lungs Intubation is taking place. For example, when a medical practitioner opens a patient's mouth with a finger and a device such as a laryngoscope and inserts a tube, the device, the finger, the tube, etc. contact the patient's teeth, and the contact causes the tooth to fall out. Or so-called tooth damage may occur. If a broken tooth gets into the stomach or lungs, it may be necessary to perform a surgical operation, which is a major problem in medical practice.
 この歯牙損傷が引き起こす種々の問題に対して、現状では、医師による事情説明や事前に折れそうな歯の治療をしておくなどの措置が取られていたりするが、例えば緊急の場合や、全身麻酔などの規模の大きな手術の前に患者側には歯の治療をするなどの時間的、精神的な余裕がない場合も多く、いずれも十分な解決策とはなっていない。その他の対応策としては、歯牙保護のためのマウスピースの如きデバイスを装着する例(例えば、特許文献1参照。)も知られている。 For various problems caused by this tooth damage, currently, doctors explain the circumstances and treat teeth that are likely to break in advance. In many cases, patients do not have time and mental leeway such as treating teeth before large-scale surgery such as anesthesia, and none of them is a sufficient solution. As another countermeasure, an example in which a device such as a mouthpiece for protecting teeth is attached (see, for example, Patent Document 1) is also known.
実用新案登録第2569263号Utility model registration No. 2569263
 しかし、前述した従来技術の如きスポーツ競技用のマウスピースでは、主に上顎と下顎を咬み合わせて使用する態様になっており、医療現場で患者が口を開けて使用する態様にはなっていない。更に、老若男女を問わずに患者に使用できる汎用性はない。 However, the above-described conventional mouthpiece for sports competition has a mode in which the upper jaw and the lower jaw are used together, and is not in a mode in which a patient opens his / her mouth at a medical site. . Furthermore, there is no versatility that can be used for patients regardless of gender.
 そこで、本発明は上述の技術的な課題に鑑み、汎用性があり、医療現場などにおいて歯牙損傷を確実に防止するような歯牙保護装置の提供を目的とする。また、本発明は、オーダーメイドではなく、緊急な場合でも装着可能であり、特に歯科や口腔関係の専門家でなくとも装着が容易な歯牙保護装置の提供を目的とする。 Therefore, in view of the above technical problems, an object of the present invention is to provide a tooth protection device that is versatile and that reliably prevents tooth damage in a medical field or the like. It is another object of the present invention to provide a tooth protection device that is not made-to-order and can be worn even in an emergency, and can be easily worn even by non-dental and oral specialists.

 図1は本発明の第1の実施形態に係る歯牙保護装置の斜視図であり、図2は第1の実施形態に係る歯牙保護装置の平面図である。これら図1,2に示されるように、第1の実施形態に係る歯牙保護装置1は、上顎歯列外側被覆部2、上顎歯列内側被覆部3、上顎歯列咬合面被覆部4、下顎歯列外側被覆部5、下顎歯列内側被覆部6、下顎歯列咬合面被覆部7、接続部8、リブ9を備えている。尚、外側とは頬側、口蓋側に相当し、内側とは舌側に相当する。上顎歯列外側被覆部2、上顎歯列内側被覆部3、上顎歯列咬合面被覆部4により上顎歯列被覆部10を構成し、下顎歯列外側被覆部5、下顎歯列内側被覆部6、下顎歯列咬合面被覆部7により下顎歯列被覆部11を構成する。これら各部2乃至9は、一体成型されており、通常状態では板状構造となる。上顎歯列被覆部10、下顎歯列被覆部11の大きさは、平均的な成人の歯列が余裕を以って収納される汎用性のあるサイズとなっているが、子供用や個人差に応じた各種のサイズや形状のものを設けても良い。 FIG. 1 is a perspective view of a tooth protection device according to the first embodiment of the present invention, and FIG. 2 is a plan view of the tooth protection device according to the first embodiment. As shown in FIGS. 1 and 2, the tooth protecting device 1 according to the first embodiment includes an upper dentition outer covering portion 2, an upper dentition inner covering portion 3, an upper dentition occlusal surface covering portion 4, and a lower jaw. A dentition outer covering portion 5, a mandibular dentition inner covering portion 6, a mandibular dentition occlusal surface covering portion 7, a connecting portion 8, and a rib 9 are provided. The outer side corresponds to the cheek side and the palate side, and the inner side corresponds to the tongue side. The maxillary dentition outer covering portion 2, the maxillary dentition inner covering portion 3, and the maxillary dentition occlusal surface covering portion 4 constitute the maxillary dentition covering portion 10, the mandibular dentition outer covering portion 5, and the mandibular dentition inner covering portion 6. The mandibular dentition covering portion 11 is constituted by the mandibular dentition occlusal surface covering portion 7. Each of these parts 2 to 9 is integrally molded and has a plate-like structure in a normal state. The maxillary dentition covering part 10 and the mandibular dentition covering part 11 have a general-purpose size in which an average adult dentition can be accommodated with a margin. Various sizes and shapes may be provided according to the requirements.
 上顎歯列外側被覆部2は、上顎歯列に沿って延長され、各歯牙の外側歯肉部分から各歯牙を覆う。上顎歯列内側被覆部3は、上顎歯列に沿って延長され、各歯列の内側歯肉部分から各歯牙を覆う。そして、上顎歯列咬合面被覆部4は、上顎歯列に沿って延長され、各歯牙の咬合面を被覆する。これらは、咬合面に垂直な方向から見て上顎歯列に沿って略U字形状に延出されている。従って、上顎歯列外側被覆部2と上顎歯列咬合面被覆部4と上顎歯列内側被覆部3により、上顎歯列の外側歯肉部分から内側歯肉部分にわたり歯牙を被覆し、保護することができる。また、前述したように上顎歯列に沿った略U字形状となっていることから、例えば歯の一部が抜けて、歯並びが揃っていないような患者に対しても簡易且つ安全に装着することができる。上顎歯列外側被覆部2及び上顎歯列内側被覆部3の少なくとも一方の上顎歯列咬合面被覆部4からの立ち上がり角度は内向きの鋭角(テーパー)にして、歯牙の豊隆部が引っ掛かるようになっている。歯牙が挿入される上顎歯列外側被覆部2と上顎歯列内側被覆部3の内面には、歯牙接触側に凸部(ディンプル)12を形成して、歯牙が食い込むような構造としている。 The upper dentition outer covering portion 2 is extended along the upper dentition and covers each tooth from the outer gingival part of each tooth. The upper dentition inner covering portion 3 extends along the upper dentition and covers each tooth from the inner gingival part of each dentition. And the upper dentition occlusal surface coating | coated part 4 is extended along the upper dentition, and covers the occlusal surface of each tooth. These are extended in a substantially U shape along the maxillary dentition as seen from the direction perpendicular to the occlusal surface. Therefore, the upper dentition outer covering portion 2, the upper dentition occlusal surface covering portion 4, and the upper dentition inner covering portion 3 can cover and protect the teeth from the outer gingival portion to the inner gingival portion of the upper dentition. . Moreover, since it is substantially U-shaped along the maxillary dentition as described above, it can be easily and safely mounted even on a patient whose teeth are not aligned and the teeth are not aligned, for example. be able to. The rising angle of at least one of the maxillary dentition outer covering portion 2 and the maxillary dentition inner covering portion 3 from the maxillary dentition occlusal surface covering portion 4 is an inward acute angle (taper) so that the ridges of the teeth are caught. It has become. Convex portions (dimples) 12 are formed on the tooth contact side on the inner surfaces of the upper dentition outer covering portion 2 and the upper dentition inner covering portion 3 into which the teeth are inserted, so that the teeth bite into the teeth.
 一方、下顎歯列外側被覆部5は、下顎歯列に沿って延長され、各歯牙の外側歯肉部分から各歯牙を覆う。下顎歯列内側被覆部6は、下顎歯列に沿って延長され、各歯列の内側歯肉部分から各歯牙を覆う。そして、下顎歯列咬合面被覆部7は、下顎歯列に沿って延長され、各歯牙の咬合面を被覆する。これらは、咬合面に垂直な方向から見て下顎歯列に沿って略U字形状に延出されている。従って、下顎歯列外側被覆部5と下顎歯列咬合面被覆部7と下顎歯列内側被覆部6により、下顎歯列の外側歯肉部分から内側歯肉部分にわたり歯牙を被覆し、保護することができる。また、前述したように下顎歯列に沿った略U字形状となっていることから、例えば歯の一部が抜けて、歯並びが揃っていないような患者に対しても簡易且つ安全に装着することができる。下顎歯列外側被覆部5及び下顎歯列内側被覆部6の少なくとも一方の下顎歯列咬合面被覆部7からの立ち上がり角度は内向きの鋭角(テーパー)にして、歯牙の豊隆部が引っ掛かるようになっている。歯牙が挿入される下顎歯列外側被覆部5と下顎歯列内側被覆部6の内面には、歯牙接触側に凸部(ディンプル)12を形成して、歯牙が食い込むような構造としている。 On the other hand, the lower dentition outer covering portion 5 is extended along the lower dentition and covers each tooth from the outer gingival portion of each tooth. The lower dentition inner covering portion 6 extends along the lower dentition and covers each tooth from the inner gingival portion of each dentition. The mandibular dentition occlusal surface covering portion 7 is extended along the mandibular dentition and covers the occlusal surface of each tooth. These are extended in a substantially U shape along the lower dentition as viewed from the direction perpendicular to the occlusal surface. Therefore, the lower dentition outer covering portion 5, the lower dentition occlusal surface covering portion 7, and the lower dentition inner covering portion 6 can cover and protect the teeth from the outer gingival portion to the inner gingival portion of the lower dentition. . Moreover, since it is substantially U-shaped along the lower jaw dentition as described above, it can be easily and safely mounted even on a patient whose teeth are missing and the teeth are not aligned. be able to. The rising angle of at least one of the lower dentition outer covering part 5 and the lower dentition inner covering part 6 from the lower dentition occlusal surface covering part 7 is an inward acute angle (taper) so that the ridges of the teeth are caught. It has become. On the inner surfaces of the lower dentition outer covering portion 5 and the lower dentition inner covering portion 6 into which the teeth are inserted, convex portions (dimples) 12 are formed on the tooth contact side so that the teeth can bite in.
 上顎歯列被覆部10と下顎歯列被覆部11とは、接続部8により屈曲自在に接続されている。より詳細には、上顎歯列咬合面被覆部4と下顎歯列咬合面被覆部7は、接続部8により接続されている。そして、この接続部8には、装着時に折りたたむ際の反発力を強くするために、該接続部辺縁にリブ9が設けられている。このリブ9により、垂直的に歯牙にかかる力を強くすることができるようになっている。 The maxillary dentition covering portion 10 and the mandibular dentition covering portion 11 are connected to each other by a connecting portion 8 so as to be freely bent. More specifically, the maxillary dentition occlusal surface covering portion 4 and the mandibular dentition occlusal surface covering portion 7 are connected by a connection portion 8. The connecting portion 8 is provided with ribs 9 on the edge of the connecting portion in order to increase the repulsive force when folded at the time of mounting. The rib 9 can strengthen the force applied to the teeth vertically.
 装着時に歯牙保護装置1が折り畳まれた様子は、例えば図3に示される通りである。この実施の形態に係る歯牙保護装置1は、上下一体型であるが、それを装着時に折り曲げようとすると、それに反発する力が働くので、口腔内の上下歯牙に装着すると、歯牙に対して垂直な力がかかることにより、歯牙から本装置1が外れにくくなる。このとき、接続部8の反発力がリブ9の存在により強められ、その反発力により上顎歯列、下顎歯列のそれぞれの歯牙を上顎歯列被覆部10、下顎歯列被覆部11が支えるようになっている。上顎歯列、下顎歯列のそれぞれの被覆部10,11は各歯列用として指定される。 The state in which the tooth protection device 1 is folded at the time of mounting is as shown in FIG. 3, for example. The tooth protection device 1 according to this embodiment is a vertically integrated type, but if it is bent at the time of wearing, a repulsive force works, so when it is attached to the upper and lower teeth in the oral cavity, it is perpendicular to the tooth. When a strong force is applied, the device 1 is unlikely to come off the tooth. At this time, the repulsive force of the connecting portion 8 is strengthened by the presence of the ribs 9, and the maxillary dentition covering portion 10 and the mandibular dentition covering portion 11 support the teeth of the maxillary dentition and the mandibular dentition by the repulsive force. It has become. The respective covering portions 10 and 11 of the upper dentition and the lower dentition are designated for each dentition.
 ここで、図4には図2のIV-IV線に沿った断面を示し、図5には図2のV-V線に沿った断面を示し説明する。図4に示されるように、前歯を被覆する部分においては、上顎咬合面被覆部4aに対して、上顎歯列外側被覆部2a及び上顎歯列内側被覆部3aの少なくとも一方(この例では、上顎歯列内側被覆部3a)の立ち上がり角度を内向きの鋭角にして歯牙の豊隆部が引っ掛かるようにしている。これは、平均的な人間の歯列の傾斜範囲に合致した角度となっており、これにより前歯を正確に被覆・保持することが可能となる。更に、歯牙接触側の凸部12により、歯牙が食い込むようになっている。これらは解剖学的寸法(歯牙単体や歯牙の長さ、幅だけではなく、交合面を横から見たスピーの湾曲等も加味)に合わせた構造となっている。また、図5に示されるように、奥歯を被覆する部分においては、上顎咬合面被覆部4bに対して、上顎歯列外側被覆部2b及び上顎歯列内側被覆部3bの少なくとも一方(この例では、下顎歯列内側被覆部3b)立ち上がり角度を内向きの鋭角にして、歯牙の豊隆部が引っ掛かるようにしている。更に、歯牙接触側の凸部12により、歯牙が食い込むようになっている。 Here, FIG. 4 shows a cross section taken along line IV-IV in FIG. 2, and FIG. 5 shows a cross section taken along line VV in FIG. As shown in FIG. 4, in the portion covering the front teeth, at least one of the upper dentition outer covering portion 2a and the upper dentition inner covering portion 3a with respect to the upper occlusal surface covering portion 4a (in this example, the upper jaw) The rising angle of the dentition inner covering portion 3a) is set to be an acute inward angle so that the ridges of the teeth are caught. This is an angle that matches the inclination range of the average human dentition, which makes it possible to accurately cover and hold the front teeth. Furthermore, the tooth bites in by the convex portion 12 on the tooth contact side. These are structured in accordance with anatomical dimensions (not only the tooth itself and the length and width of the tooth but also the curvature of the speed when the mating surface is viewed from the side). Further, as shown in FIG. 5, in the portion covering the back teeth, at least one of the maxillary dentition outer covering portion 2b and the maxillary dentition inner covering portion 3b with respect to the maxillary occlusal surface covering portion 4b (in this example, The mandibular dentition inner covering portion 3b) The rising angle is set to an inward acute angle so that the ridges of the teeth are caught. Furthermore, the tooth bites in by the convex portion 12 on the tooth contact side.
 上顎歯列咬合面被覆部4、下顎歯列咬合面被覆部7の長さは、歯牙の部位(中切歯、側切歯、犬歯、第一小臼歯、第二大臼歯、第二大臼歯、第三大臼歯)や、上顎、下顎によって変えており、その長さは、医学的に根拠のあるデータに基づいて、例えば各歯牙の長さより若干(例えば1mm)小さ目にすることで、軟性樹脂が歯牙の豊隆部に引っ掛るようにしている。これにより、歯牙をしっかりと被覆、保持することができる。 The lengths of the maxillary dentition occlusal surface covering portion 4 and the mandibular dentition occlusal surface covering portion 7 are the tooth parts (middle incisors, side incisors, canines, first premolars, second premolars, second premolars). , Third molar), maxilla and mandible, and the length is soft, for example, slightly smaller (for example, 1 mm) than the length of each tooth based on medically-founded data The resin is caught on the ridges of the teeth. Thereby, a tooth can be coat | covered and hold | maintained firmly.
 図6には、図4の構成により実際に前歯を被覆した様子を示している。この図6に示されるように、上顎歯列外側被覆部2aが歯牙60の外側及び外側歯肉を被覆し、上顎歯列内側被覆部3aが歯牙60の内側及び内側歯肉を被覆し、上顎歯列咬合面被覆部4aが歯牙60の咬合面を被覆するようになっている。また、凸部12により、歯牙が食い込むようになっている。 FIG. 6 shows a state where the front teeth are actually covered by the configuration of FIG. As shown in FIG. 6, the upper dentition outer covering portion 2 a covers the outer and outer gingiva of the tooth 60, the upper dentition inner covering portion 3 a covers the inner and inner gingiva of the tooth 60, and the upper dentition The occlusal surface covering portion 4 a covers the occlusal surface of the tooth 60. Further, the convex portion 12 bites the teeth.
 上述した構成の歯牙保護装置1の各被覆部2乃至7及び接続部8、リブ9は一体成型されるものであるが、その材質としては、粘性が高く、伸縮性に富んだ材料として、例えばエチレン-酢酸ビニル共重合樹脂(EVA;Ethylene-Vinyl Acetate)やシリコン系材料などを採用することができる。また、広くは軟質の熱可塑性合成樹脂材などを用いることができ、例えばポリオレフィン樹脂、ポリアミド樹脂、ポリエステル樹脂、(メタ)アクリル樹脂、塩化ビニル樹脂、塩化ビニリデン樹脂、ポリエーテルサルホン、エチレン-ビニルアルコール共重合体なども採用できる。この中でも特にポリオレフィン樹脂としては、例えば、高密度ポリエチレン、中密度ポリエチレン、高圧法低密度ポリエチレン、直鎖状低密度ポリエチレン、前述したエチレン-酢酸ビニル共重合体等のポリエチレン系樹脂、エチレン-αオレフィンランダム共重合体等のオレフィン系エラストマー、ポリプロピレン、エチレン-プロピレンランダム共重合体、α-オレフィン-プロピレンランダム共重合体等のポリプロピレン系樹脂や、環状ポリオレフィン樹脂、これらの混合物の単層、および多層フィルムなどが挙げられる。これらの樹脂は、耐熱性向上等を目的として一部架橋されていても良い。 Each of the covering portions 2 to 7 and the connecting portions 8 and the ribs 9 of the tooth protection device 1 having the above-described configuration are integrally molded. As a material thereof, for example, as a material having high viscosity and high stretchability, Ethylene-vinyl acetate copolymer resin (EVA; Ethylene-Vinyl® Acetate) or silicon-based material can be used. In addition, a wide range of soft thermoplastic synthetic resin materials can be used. For example, polyolefin resin, polyamide resin, polyester resin, (meth) acrylic resin, vinyl chloride resin, vinylidene chloride resin, polyethersulfone, ethylene-vinyl Alcohol copolymers can also be employed. Among these, particularly polyolefin resins include, for example, high-density polyethylene, medium-density polyethylene, high-pressure method low-density polyethylene, linear low-density polyethylene, polyethylene-based resins such as the ethylene-vinyl acetate copolymer described above, and ethylene-α olefins. Olefin-based elastomers such as random copolymers, polypropylene-based resins such as polypropylene, ethylene-propylene random copolymers, α-olefin-propylene random copolymers, cyclic polyolefin resins, single layers of these mixtures, and multilayer films Etc. These resins may be partially crosslinked for the purpose of improving heat resistance.
 歯牙保護装置1を軟質の熱可塑性合成樹脂材で一体成型することで、医療行為中に各被覆部2乃至7に指や器具などが当たった場合でも、その衝撃を吸収し和らげることができる。また、各被覆部2乃至7を軟質の熱可塑性合成樹脂材で構成することで、患者等の使用者の歯肉に対しても当たりが柔軟になることから装着時の違和感も防止できる。特に歯並びの揃っていない、歯の一部が抜けているような患者に対しても汎用性のある構造にて簡易且つ迅速に、しかも安全に装着することができる。 By integrally molding the tooth protection device 1 with a soft thermoplastic synthetic resin material, even if a finger or an instrument hits each of the covering portions 2 to 7 during a medical practice, the impact can be absorbed and reduced. Moreover, since each coating | coated part 2 thru | or 7 is comprised with a soft thermoplastic synthetic resin material, since a hit also becomes flexible with respect to gingiva of users, such as a patient, the discomfort at the time of mounting | wearing can also be prevented. In particular, it can be easily, quickly and safely mounted with a versatile structure even for a patient whose teeth are not aligned and where a part of the teeth is missing.
 本発明の第1の実施形態に係る歯牙保護装置によれば、使用者の歯に対して被覆部を被せるように装着し、接続部の弾性力により口を開いた状態でも歯牙の被覆状態を維持することができることから、歯牙損傷を確実に防止することができる。 According to the tooth protecting apparatus according to the first embodiment of the present invention, the covering state of the tooth can be maintained even when the mouth is opened by the elastic force of the connecting portion, so that the user's teeth are covered with the covering portion. Since it can be maintained, tooth damage can be reliably prevented.
 また、この本発明の第1の実施形態に係る歯牙保護装置は、オーダーメイドではなく樹脂成型などにより汎用品として使用者に提供されるが、この歯牙保護装置は柔軟であることから特に歯科や口腔関係の専門家でなくとも装着が容易であり、緊急な場合でも装着可能である。更に、上顎歯列被覆部と下顎歯列被覆部を一体成型としたことから、製造コストも削減される。 In addition, the tooth protection device according to the first embodiment of the present invention is provided to the user as a general-purpose product by resin molding or the like instead of being made to order.

 歯牙被覆樹脂部20は、比較的に柔らかな樹脂材を成型して形成されるものであり、歯の咬み合い面に垂直な方向から見て当該歯牙被覆樹脂部20は上顎歯列若しくは下顎歯列に沿って延長された略U字形状に構成される。また歯牙被覆樹脂部20の被覆部分の断面については、具体的には、図8のIX-IX線に沿った断面を示す図9や図8のX-X線に沿った断面を示す図10にそれぞれ示すように、歯列の外側(唇側)の歯肉に当接する外側歯肉当接部21から折れ曲がるように立ち上がり、歯の形状に沿って各歯を被覆するように延長され、歯列の内側に至っては再度大きく折れ曲がって歯列の内側(舌側)の歯肉に当接する内側歯肉当接部22まで延長されている。歯の形状に沿った部分については、前歯では図9に示すように、前歯の外側(唇側)を被覆する前歯外側被覆部23と前歯の内側(舌側)を被覆する前歯内側被覆部25が前歯の切縁に沿って折れ曲がるように連続している。一方、奥歯では図10に示すように、奥歯の外側を被覆する奥歯外側被覆部26が歯列の外側(唇側)の歯肉に当接する外側歯肉当接部21から折れ曲がるように立ち上がり、奥歯の内側を被覆する奥歯内側被覆部28が歯列の内側(舌側)の歯肉に当接する内側歯肉当接部22から折れ曲がるように立ち上がり、これら奥歯外側被覆部26と奥歯内側被覆部28との間に奥歯の咬合面に沿って奥歯咬合面被覆部27が設けられている。 The tooth covering resin portion 20 is formed by molding a relatively soft resin material, and the tooth covering resin portion 20 is viewed from a direction perpendicular to the tooth biting surface. It is comprised in the substantially U shape extended along the row | line | column. Further, as for the cross section of the covering portion of the tooth covering resin portion 20, specifically, FIG. 9 showing the cross section along the line IX-IX in FIG. 8 and FIG. 10 showing the cross section along the line XX in FIG. As shown in Fig. 1, each of the teeth rises so as to bend from the outer gingival contact portion 21 that contacts the gingiva on the outer side (lip side) of the dentition, and is extended so as to cover each tooth along the shape of the teeth. The inner gingiva contact portion 22 that is bent back to the inner side and is bent again to contact the gingiva on the inner side (lingual side) of the dentition is extended. As for the portion along the shape of the teeth, as shown in FIG. 9, in the front teeth, the front tooth outer covering portion 23 covering the outer side (lip side) of the front teeth and the front tooth inner covering portion 25 covering the inner side (lingual side) of the front teeth. Is continuous along the cutting edge of the front tooth. On the other hand, as shown in FIG. 10, at the back teeth, the back tooth outer covering portion 26 that covers the outside of the back teeth rises so as to bend from the outer gingival contact portion 21 that contacts the gingiva on the outer side (lip side) of the dentition. The back tooth inner covering portion 28 that covers the inner side rises so as to bend from the inner gingival contact portion 22 that contacts the gingiva on the inner side (lingual side) of the dentition, and between these outer teeth outer covering portion 26 and the back tooth inner covering portion 28. The back occlusal surface covering portion 27 is provided along the occlusal surface of the back teeth.
 歯牙被覆樹脂部20は、所要の厚みを有して上顎歯列若しくは下顎歯列をほぼ全体的に覆う構造を有しており、その内側面となる歯牙対向面29は各歯の部分で凹部となり、この歯牙対向面29が上顎歯列若しくは下顎歯列の収納部24を構成する。歯牙被覆樹脂部20の大きさは、平均的な成人の歯列が余裕を以って歯牙被覆樹脂部20の収納部24に収納されるサイズであり、子供用や個人差に応じた各種のサイズや形状のものを設けても良い。 The tooth coating resin part 20 has a structure having a required thickness and substantially covering the upper dentition or the lower dentition, and the tooth-facing surface 29 serving as the inner side surface is a concave portion at each tooth portion. Thus, the tooth facing surface 29 constitutes a storage section 24 for the upper or lower jaw dentition. The size of the tooth covering resin portion 20 is a size that allows an average adult dentition to be stored in the storage portion 24 of the tooth covering resin portion 20 with a margin. A size or shape may be provided.
 歯牙被覆樹脂部20には、例えば軟質の熱可塑性合成樹脂材などを用いることができ、例えばポリオレフィン樹脂、ポリアミド樹脂、ポリエステル樹脂、(メタ)アクリル樹脂、塩化ビニル樹脂、塩化ビニリデン樹脂、ポリエーテルサルホン、エチレン-ビニルアルコール共重合体などが挙げられる。この中でも特にポリオレフィン樹脂としては、例えば、高密度ポリエチレン、中密度ポリエチレン、高圧法低密度ポリエチレン、直鎖状低密度ポリエチレン、エチレン-酢酸ビニル共重合体等のポリエチレン系樹脂、エチレン-αオレフィンランダム共重合体等のオレフィン系エラストマー、ポリプロピレン、エチレン-プロピレンランダム共重合体、α-オレフィン-プロピレンランダム共重合体等のポリプロピレン系樹脂や、環状ポリオレフィン樹脂、これらの混合物の単層、および多層フィルムなどが挙げられる。これらの樹脂は、耐熱性向上等を目的として一部架橋されていても良い。 For example, a soft thermoplastic synthetic resin material or the like can be used for the tooth covering resin portion 20. For example, polyolefin resin, polyamide resin, polyester resin, (meth) acrylic resin, vinyl chloride resin, vinylidene chloride resin, polyether sal Hong, ethylene-vinyl alcohol copolymer and the like. Among these, particularly polyolefin resins include, for example, high-density polyethylene, medium-density polyethylene, high-pressure method low-density polyethylene, linear low-density polyethylene, polyethylene-based resins such as ethylene-vinyl acetate copolymer, and ethylene-α-olefin random copolymer. Olefin elastomers such as polymers, polypropylene resins such as polypropylene, ethylene-propylene random copolymers, α-olefin-propylene random copolymers, cyclic polyolefin resins, single layers of these mixtures, and multilayer films. Can be mentioned. These resins may be partially crosslinked for the purpose of improving heat resistance.
 歯牙被覆樹脂部20を軟質の熱可塑性合成樹脂材で構成することで、医療行為中に歯牙被覆樹脂部20に指や器具などが当たった場合でも、その衝撃を吸収し和らげることができる。また、外側歯肉当接部21と内側歯肉当接部22は、当該歯牙保護装置100の装着時においては、それぞれ歯肉の表面に広がるように密着し、その歯肉の部分を保護させることができると共に、吸盤のように歯肉表面に歯牙被覆樹脂部20を吸着させるように機能させることができ、歯牙保護装置100の装着を安定した装着にすることができる。また、歯牙被覆樹脂部20を軟質の熱可塑性合成樹脂材で構成することで、患者等の使用者の歯肉に対しても当たりが柔軟になることから装着時の違和感も防止できる。 By configuring the tooth covering resin portion 20 with a soft thermoplastic synthetic resin material, even when a finger or an instrument hits the tooth covering resin portion 20 during a medical practice, the impact can be absorbed and reduced. In addition, the outer gingival contact portion 21 and the inner gingival contact portion 22 are in close contact with each other so as to spread on the surface of the gingiva when the tooth protection device 100 is mounted, and can protect the gingival portion. It can be made to function so that the tooth covering resin part 20 is adsorbed to the gingival surface like a sucker, and the attachment of the tooth protection device 100 can be made stable. Moreover, since the tooth coating resin portion 20 is made of a soft thermoplastic synthetic resin material, the contact with the user's gingiva can be made flexible, so that a sense of incongruity at the time of wearing can be prevented.
 歯牙被覆樹脂部20を単一の樹脂で構成するのではなく、複数の種類層を重ねた多層構造とすることもでき、例えばガスバリア性を重視する場合では、エチレンビニルアルコール共重合体(EVOH)、ポリビニルアルコール(PVA)、ポリ塩化ビニリデン(PVDC)、メタキシレンダイアミンとアジピン酸の共重合体(MXナイロン,MXDNy)、ポロアクリロニトリル(PAN)等のフィルムや樹脂からなる層や、これらを含む積層フィルム(例えば、ポリアミド/EVOH/ポリアミドの積層フィルム)、また、ポリエステルフィルムやポリアミドフィルムにシリカやアルミナを蒸着した透明蒸着フィルム、更に、上記バリアー性樹脂を含有したコーティング剤を塗布したフィルム等が使用できる。なお、歯牙被覆樹脂部20の形成には、金型を用いた射出成型の他、所定の樹脂シートを真空成型するようにしても良い。 The tooth covering resin portion 20 may not be composed of a single resin, but may have a multilayer structure in which a plurality of types of layers are stacked. For example, when importance is attached to gas barrier properties, an ethylene vinyl alcohol copolymer (EVOH) , Polyvinyl alcohol (PVA), polyvinylidene chloride (PVDC), metaxylene diamine and adipic acid copolymer (MX nylon, MXDNy), layers made of films and resins such as poloacrylonitrile (PAN), and the like Laminated films (for example, polyamide / EVOH / polyamide laminated films), transparent deposited films obtained by depositing silica or alumina on polyester films or polyamide films, and films coated with a coating agent containing the above barrier resin Can be used. Note that the tooth covering resin portion 20 may be formed by vacuum molding a predetermined resin sheet in addition to injection molding using a mold.
 歯牙被覆樹脂部20に対して一体的となるように、ステンレスなどの金属製の針金材を屈曲して形成されたクリップ30が取り付けられている。クリップ30は、具体的には、左右に一対の前側クリップ33、左右に一対の中央クリップ32、左右に一対の奥側クリップ31の合計6個のクリップからなる。クリップ31~33は、それぞれ略8の字状の両端部をそれぞれ歯の側面に合わせるように下向きに折り曲げた形状を有しており、下端部側はやや閉じるように両端間の距離が狭められている。歯に対して当該歯牙保護装置100を装着する場合には、各クリップ31~33の下端側を広げるようにして、各歯を歯牙被覆樹脂部20の収納部24の内部に収納する。このとき歯牙被覆樹脂部20を各クリップ31~33がその下端部に加わる弾性力で患者等の使用者の歯肉部などに確実に圧接し、当該歯牙保護装置100を外そうとするような力を加えない状態では、歯牙被覆樹脂部20はそのまま歯の周囲に固定されたままとなる。 A clip 30 formed by bending a metal wire material such as stainless steel is attached so as to be integrated with the tooth coating resin portion 20. Specifically, the clip 30 includes a total of six clips including a pair of front clips 33 on the left and right, a pair of central clips 32 on the left and right, and a pair of back clips 31 on the left and right. Each of the clips 31 to 33 has a shape that is bent downward so that both ends of each of the approximately 8 shapes are aligned with the side surfaces of the teeth, and the distance between both ends is narrowed so that the lower end side is slightly closed. ing. When the tooth protection device 100 is attached to a tooth, each tooth is housed in the housing portion 24 of the tooth covering resin portion 20 with the lower ends of the clips 31 to 33 widened. At this time, the tooth covering resin portion 20 is surely pressed against the gingival portion of the user such as a patient by the elastic force applied to the lower end of each clip 31 to 33, and the force to try to remove the tooth protection device 100 In the state where no is added, the tooth covering resin portion 20 remains fixed around the teeth as it is.
 第2の実施形態においては、クリップ30を金属製の針金材を加工したものとして説明したが、歯牙被覆樹脂部20を歯牙若しくは歯肉に対して固定する機能を有していれば、材料はプラスチックやその他の複合材料であっても良く、さらに金属製クリップとプラスチック製クリップとが混在するような組み合わせも可能である。クリップ30を矩形状の略8の字形状として説明したが、他の形状であっても良く、例えば略コ字状や略U字状などであっても良い。さらに、クリップ30の形状も弾性を有した金属板のような他の形状であっても良い。また、本実施形態では、左右3個ずつの合計6個をクリップとして使用する例を説明しているが、例えば、左右2個ずつや左右4個ずつのようにクリップの数を変えることは任意であり、各クリップの歯牙被覆樹脂部20を固定する力も均等であっても良く、場所に応じて異なるようにしても良い。 In the second embodiment, the clip 30 has been described as a metal wire material processed. However, the material is plastic if it has a function of fixing the tooth covering resin portion 20 to the tooth or gum. Or other composite materials, and a combination in which a metal clip and a plastic clip are mixed is also possible. Although the clip 30 has been described as having a rectangular shape of approximately 8 characters, other shapes may be used, for example, a substantially U shape or a substantially U shape. Furthermore, the shape of the clip 30 may be another shape such as a metal plate having elasticity. In the present embodiment, an example in which a total of six left and right three is used as a clip has been described. However, for example, it is arbitrary to change the number of clips such as two left and right or four left and right. And the force which fixes the tooth | gear covering resin part 20 of each clip may be equal, and you may make it differ according to a place.
 歯牙被覆樹脂部20の外側に各クリップ31~33を外嵌するようにしても良いが、歯牙被覆樹脂部20の外側に各クリップ31~33を外嵌した後、さらに歯牙被覆樹脂部20に接着する保護フィルムを被せ、各クリップ31~33と歯牙被覆樹脂部20を一体化させても良い。本実施形態の歯牙保護装置100では、各クリップ31~33に対して薄い保護フィルムが被覆されており、この保護フィルムによって各クリップ31~33の位置が固定される。 The clips 31 to 33 may be externally fitted to the outside of the tooth coating resin portion 20, but after the clips 31 to 33 are externally fitted to the outside of the tooth coating resin portion 20, the clips are further attached to the tooth coating resin portion 20. The clips 31 to 33 and the tooth covering resin portion 20 may be integrated with a protective film to be adhered. In the tooth protection device 100 of this embodiment, a thin protective film is coated on each of the clips 31 to 33, and the position of each of the clips 31 to 33 is fixed by this protective film.
 次に、歯牙被覆樹脂部20の収納部24には、歯牙との密着性を高めるための充填材40が配される。この充填材40は、ペースト状の樹脂材からなり、例えばワセリンやパラフィン等の鉱油成分中にカルボキシメチルセルロースやポリエチレンオキシド等の水溶性高分子を分散させたもの、酢酸ビニル系樹脂やセルロース誘導体及びこれらの塩、粘着性の充填材として、カラヤガム、アラビアガム、トラガカントガム等の天然性物質や、シリコーン樹脂、或はアルギン酸ナトリウム、カルボキシメチルセルロースナトリウム、ポリアクリル酸の金属塩、ポリエチレンオキシド、ポリビニルピロリドン等の合成又は半合成高分子が単独または複数の組み合わせなどであっても良い。充填材40は慣用の剥離剤や軟化剤を含有していても良い。また、セルロースや澱粉などの天然材料を用いることもでき、樹脂製の粘土や小麦粉を基材とした粘土などを充填材としても良い。 Next, a filler 40 for increasing the adhesion to the teeth is disposed in the storage portion 24 of the tooth covering resin portion 20. The filler 40 is made of a paste-like resin material. For example, a water-soluble polymer such as carboxymethyl cellulose or polyethylene oxide dispersed in a mineral oil component such as petrolatum or paraffin, a vinyl acetate resin, a cellulose derivative, or the like. Natural materials such as karaya gum, gum arabic, and tragacanth gum, silicone resin, sodium alginate, sodium carboxymethylcellulose, polyacrylic acid metal salt, polyethylene oxide, polyvinylpyrrolidone, etc. Alternatively, the semi-synthetic polymer may be used alone or in combination. The filler 40 may contain a conventional release agent or softener. Natural materials such as cellulose and starch can also be used, and resin-made clay, wheat-based clay, or the like may be used as the filler.
 充填材40は、歯牙被覆樹脂部20の収納部24の全空間を満たすように充填されるのではなく、底面側に歯を挿入した場合の嵩に相当する体積だけ空間として空けているような量だけ配設されている。このような充填材40の量とすることで、歯牙保護装置100の装着時には円滑に歯を歯牙被覆樹脂部20の収納部24に入れることができ、充填材40が外側にあふれるような問題も生じないことになる。 The filling material 40 is not filled so as to fill the entire space of the storage portion 24 of the tooth covering resin portion 20, but is vacated as a space corresponding to the volume when teeth are inserted on the bottom surface side. The amount is arranged. By setting the amount of the filler 40 as described above, when the tooth protection device 100 is mounted, the teeth can be smoothly put into the storage portion 24 of the tooth covering resin portion 20, and there is a problem that the filler 40 overflows outside. It will not occur.
 充填材40は、個人差が大きいものと予想される患者等の使用者の歯列に対して、当該歯牙保護装置100の装着時には歯牙被覆樹脂部20の収納部24に充填されている充填材40自体を圧力で変形させて、義歯用安定剤のように歯の表面への密着面積を広げるように機能するものである。このため歯牙保護装置100は確実に患者等の使用者の歯に対して固定されることになり、更に、医療行為中に歯牙被覆樹脂部20に指や器具などが当たった場合でも、充填材40は歯牙被覆樹脂部20と歯牙の間の緩衝層として機能することから、歯牙の損傷を更に防止することが可能である。 The filling material 40 is filled in the storage portion 24 of the tooth covering resin portion 20 when the tooth protection device 100 is attached to a dentition of a user such as a patient who is expected to have a large individual difference. 40 itself is deformed by pressure, and functions to expand the contact area to the tooth surface like a denture stabilizer. For this reason, the tooth protection device 100 is surely fixed to the teeth of a user such as a patient, and further, even when a finger or an instrument hits the tooth coating resin portion 20 during a medical practice, the filling material Since 40 functions as a buffer layer between the tooth coating resin portion 20 and the tooth, it is possible to further prevent damage to the tooth.
 この充填材40は、歯牙被覆樹脂部20の収納部24に予め充填されていることから、例えば緊急の患者に対しても即座に歯にあてがうようにして当該歯牙保護装置100を素早く装着でき、患者を歯牙損傷から守ることができる。装着前の段階で、歯牙被覆樹脂部20の収納部24はその底面側を閉塞するようにシール部50によって密閉状態となっており、前述の充填材40の乾燥などを防止して充填材40自体の流動性を維持させることができる。 Since the filling material 40 is pre-filled in the storage portion 24 of the tooth covering resin portion 20, for example, the tooth protection device 100 can be quickly mounted so as to be immediately applied to teeth even for an emergency patient. The patient can be protected from tooth damage. In the stage before mounting, the storage portion 24 of the tooth covering resin portion 20 is hermetically sealed by the seal portion 50 so as to close the bottom surface side thereof, and prevents the filler 40 from drying and the like. The fluidity of itself can be maintained.
 本実施形態においては、シール部50は、例えば伸縮性に富む薄いフィルムなどで構成することができ、例えばパラフィルム(登録商標)などの樹脂フィルムを用いることができる。このような伸縮性に富む薄いフィルムを用いることで、当該歯牙保護装置100を装着する場合に、そのままシール部50に対して歯をあてがっていくことで、歯を歯牙被覆樹脂部20の収納部24の内側にシール部50を歯の形状に沿って延伸させながら押し込んでいくことが出来る。このようにシール部50を歯牙被覆樹脂部20の底面に残したまま歯牙保護装置100を装着することで、歯牙保護装置100を外す場合に、充填材40の一部が脱落してしまうことがなく、シール部50により密閉された空間内に充填材40が止まることになり、例えば充填材40の一部が脱落して患者の気管支などに入り込むような危険は未然に防止されることになる。 In the present embodiment, the seal portion 50 can be made of, for example, a thin film rich in stretchability, for example, a resin film such as Parafilm (registered trademark). By using such a thin film rich in stretchability, when the tooth protection device 100 is mounted, the teeth are directly applied to the seal portion 50, so that the teeth are stored in the housing portion of the tooth coating resin portion 20. The seal part 50 can be pushed into the inner side of 24 while extending along the shape of the teeth. In this way, when the tooth protection device 100 is removed by attaching the tooth protection device 100 with the seal portion 50 left on the bottom surface of the tooth coating resin portion 20, a part of the filler 40 may fall off. However, the filler 40 stops in the space sealed by the seal portion 50. For example, a risk that a part of the filler 40 falls off and enters the patient's bronchus or the like is prevented. .
 なお、本実施形態では、シール部50は使用に際して剥がさず、そのまま伸縮性を利用して歯を押し込んで使用するものとして説明したが、使用に際してシール部50を剥がして使用する様な構成とすることも可能である。また、シール部50を伸縮性に富むフィルムとした場合には、歯牙被覆樹脂部20の収納部24には気密性が高まることになるが、装着時には、シール部50と充填材40の間の空間の気体を抜くような小穴を設けることで、当該歯牙保護装置100の確実な装着が実現可能となる。また、延伸性に富むシール部を予め歯牙被覆樹脂部20の内壁と充填材40の表面に密着するように配設しても良い。このようにシール部50と充填材40を予め密着させることで、シール部50と充填材40の間の気体の問題は解決される。 In the present embodiment, the seal portion 50 is not peeled off during use, but is used by pushing in the teeth as it is using stretchability. However, the seal portion 50 is peeled off before use. It is also possible. Further, when the seal part 50 is made of a highly stretchable film, the airtightness of the storage part 24 of the tooth covering resin part 20 is increased. Providing the tooth protection device 100 with certainty is possible by providing a small hole through which the gas in the space is extracted. Moreover, you may arrange | position the seal | sticker part rich in a drawability so that it may contact | adhere to the inner wall of the tooth coating resin part 20, and the surface of the filler 40 previously. Thus, the gas problem between the seal part 50 and the filler 40 is solved by bringing the seal part 50 and the filler 40 into close contact in advance.
 次に、図11乃至図13を参照しながら、第2の実施形態の歯牙保護装置100の装着動作について説明する。図11に示すように、第2の実施形態の歯牙保護装置100の装着時には、先ず、各歯60の先端である前歯の切縁61や奥歯の咬合部を歯牙被覆樹脂部20のシール部50に合わせる。 Next, the mounting operation of the tooth protection device 100 according to the second embodiment will be described with reference to FIGS. As shown in FIG. 11, when the tooth protection device 100 according to the second embodiment is mounted, first, the front edge incision 61 and the occlusal portion of the back teeth, which are the tips of the teeth 60, are sealed with the seal portion 50 of the tooth coating resin portion 20. To match.
 次に図12に示すように、歯60を歯牙被覆樹脂部20の収納部24に押し込む。この時、クリップ33は歯の通過に伴ってその開口側が開くように動かされ、歯60をクリップ33からの弾性力に抗しながら奥まで挿入して行く。歯が歯牙被覆樹脂部20の収納部24の内部に進行するに従って充填材40が歯牙被覆樹脂部20内壁に沿って外側に流動する。歯の歯牙被覆樹脂部20の収納部24内部の進行に従って、シール部50は延伸され十分に延びながら、歯の表面を被覆する。 Next, as shown in FIG. 12, the tooth 60 is pushed into the storage portion 24 of the tooth covering resin portion 20. At this time, the clip 33 is moved so that the opening side is opened as the teeth pass, and the teeth 60 are inserted to the back while resisting the elastic force from the clip 33. The filler 40 flows outward along the inner wall of the tooth coating resin portion 20 as the teeth progress into the storage portion 24 of the tooth coating resin portion 20. The seal part 50 covers the tooth surface while being stretched and sufficiently extended as the inside of the storage part 24 of the tooth covering resin part 20 of the tooth extends.
 図13は歯60を歯牙被覆樹脂部20の収納部24の内部に十分に押し込んだところを示している。この段階で、クリップ33はその弾性力によって歯牙被覆樹脂部20を歯牙又は歯肉部に押圧し、当該歯牙保護装置100を確実に患者等の使用者の歯牙に対して固定する。装着された段階で、患者等の使用者の歯牙は充填材40に包まれると共に軟質の熱可塑性合成樹脂からなる歯牙被覆樹脂部20に包まれることになり、医者の指や器具などが歯に当たるようなことがあっても、歯牙損傷が生ずるような状況を未然に防止することができる。 FIG. 13 shows a state where the tooth 60 is sufficiently pushed into the storage portion 24 of the tooth covering resin portion 20. At this stage, the clip 33 presses the tooth covering resin part 20 against the tooth or gingival part by its elastic force, and securely fixes the tooth protection device 100 to the tooth of the user such as a patient. At the stage of wearing, the teeth of a user such as a patient are wrapped in the filling material 40 and in the tooth covering resin portion 20 made of a soft thermoplastic synthetic resin, and a doctor's finger or instrument hits the teeth. Even in such a case, it is possible to prevent a situation in which tooth damage occurs.
 本発明の第2の実施形態に係る歯牙保護装置によれば、使用者の歯に対して歯牙被覆樹脂部を被せるように装着し、その際には弾性固定部によって口を開いた状態でも歯牙の被覆状態を維持することができることから、歯牙損傷を確実に防止することができる。また、本発明の第2の実施形態に係る歯牙保護装置は、オーダーメイドではなく樹脂成型などにより汎用品として使用者に提供されるが、歯牙被覆樹脂部は柔軟であることから特に歯科や口腔関係の専門家でなくとも装着が容易であり、緊急な場合でも装着可能である。 According to the tooth protecting apparatus according to the second embodiment of the present invention, the tooth is mounted so that the user's teeth are covered with the tooth covering resin portion, and the mouth is opened by the elastic fixing portion. Since the covering state can be maintained, tooth damage can be reliably prevented. In addition, the tooth protection device according to the second embodiment of the present invention is provided to the user as a general-purpose product by resin molding or the like instead of being made to order. It is easy to install even if it is not a related expert, and can be installed even in an emergency.
