Description

本考案は、高齢者や事故等で上下歯の大部分を総入歯とした個人等の上側総入歯装着者の、食事時の上側総入歯の自然落下による同入歯の噛み込みやで口内負傷を発生する機会の防止による、快適な総入歯の使用の可能が約束される技術に関する。  The present invention can prevent oral injuries caused by biting of the upper full denture during the meal due to the natural fall of the upper total denture during meals, etc. The present invention relates to a technology that promises the possibility of using a comfortable full denture by preventing the occurrence of an occurrence.

近年では高齢者の歯の脱落に伴い歯科医師から勧められる咬合可能手段は、上顎の歯が全て抜けた場合には、総入歯にするのが普通に行なわれているが、この総入歯は、口蓋と義歯床との間に吐く息吹く息が喉側から侵入しやすく、その為に総義歯が外れ易くなったり、また、脱歯後の陥没した肉穴と完全に嵌合し合わない義歯部分に局所的な力が過剰に加わると、総入歯が外れて義歯を歯肉部で噛んでしまう痛手を生じてしまう場合が多い事実からの回避には、ゆっくりと気長に、総入歯を定位置に直し直しをしてからの噛み込みをする他は無く、その苦労の実情に甘んじなくてはならなかった過去の歴史が存在する。  In recent years, the occlusal means recommended by the dentist with the dropping of the teeth of the elderly is usually done with full dentures when all of the maxillary teeth are missing, The portion of the denture where breathing between the palate and the denture base can easily invade from the throat side, so that the complete denture can easily come off, and the dentured hole after the denture does not fit perfectly. To avoid the fact that excessive application of excessive force on the teeth often results in a painful situation in which the full dentures come off and bite the dentures in the gingiva, slowly and slowly There is no other way to bite after reworking, and there is a past history that had to be relieved by the actual situation of the struggle.

近年になっは、インプラントの技術が進行してきたが、歯１本で３０万円以上では、一般的には、保険が利かずで、普及には高級すぎる技能である難点があった。  In recent years, implant technology has progressed. However, with a tooth of 300,000 yen or more, there is generally a problem that the insurance is not effective and is too expensive to spread.

上に述べたインプラントの技術は、顎の骨を削ってその中に義歯の根元を埋め込む作業が伴い、高度な技術を要したゆえ、既製品が大量に作成されて、どのような技術士がやっても確実に総義歯使用者の使用感を満足させるには、別に、手軽に構成でき、かつ、使用者が満足できる様にする課題が生じている。  The implant technology described above involves cutting the jaw bone and embedding the root of the denture in it, and because it required advanced technology, a large number of ready-made products were created. In order to reliably satisfy the feeling of use of the complete denture user, there is a problem that it can be easily configured and satisfied by the user.

それには、まず、上顎部からの自然落下を防止する手段の解決だとの課題に焦点が集まると言える。  To that end, first of all, it can be said that the focus is on the solution of a means for preventing natural fall from the upper jaw.

上に述べた上顎部面からの総入歯の落下については、従来は、空気圧１気圧を利用して総義歯の裏面と上顎骨上の肉面との間に粘着性物質やテープを挿入して一時的な真空にかかる１気圧による総義歯の落下を防止させようとしていたが、実用としては、咬合時には舌等の接触によるその真空保持が困難となる為に、すぐに自然落下してしまう結果からの、予想外の使用者の不満となっている点も克服できるようにする点も課題となっていた。  With regard to the fall of the total denture from the maxillary surface described above, conventionally, an adhesive substance or tape is inserted between the back surface of the complete denture and the flesh surface on the maxilla using an air pressure of 1 atm. The attempt was made to prevent the denture from dropping due to 1 atm applied to a temporary vacuum, but as a practical matter, it would be difficult to hold the vacuum due to contact with the tongue or the like during occlusion, so it would fall spontaneously immediately. Another problem was that it was possible to overcome the unexpected dissatisfaction of users.

上の課題を解決するためには、第１に、最も単純な形態としては、柔軟で、かつ、強力な弾性力を持つ「ばね」を上下の総義歯あるいは固定できる最奥等の部分義歯に渡し、かつ、その使用感を極力排除するようにして、上顎部からの落下を防止させる。  In order to solve the above problems, first, as the simplest form, a flexible and strong elastic “spring” can be used for upper and lower complete dentures or the innermost partial denture that can be fixed. Handing over and eliminating the feeling of use as much as possible to prevent falling from the upper jaw.

第２に、咬合運動が１億回でも使用できるとするばねの支持部における複数あるいは単数の総義歯の、左右又は片方かの、ばねの上下の両端部での接続部における荷重振動に対しても、支持埋め込み部分との接続には、歯形なり歯面を持つ金属部の歯形間での溶接等の結合を完全にさせておく。  Secondly, with respect to load vibration at the connection part at both the upper and lower ends of the spring of the left and right or one of the complete dentures in the spring support part that can be used even 100 million times of occlusal movement However, for the connection with the support embedded portion, the coupling such as welding between the tooth forms of the metal part having the tooth form or the tooth surface is made complete.

第３に、前項「０００８」のばねには、単一ばねを使用も可能ではあるが、不時の折損の場合での頬内部損傷を防止するためには、円形つる巻ばねや楕円形つる巻ばねを単独使用するよりも、複数個を使用する方が効果的である。  Thirdly, a single spring can be used for the spring of “0008” in the preceding paragraph, but in order to prevent damage to the cheek inside in the event of an accidental breakage, a circular helical spring or an elliptical crane It is more effective to use a plurality than a single spring.

第４に、万が一のつる巻ばねの破損時の負傷や使用時のつる巻ばね間の隙間の開閉時に頬内肉部が挟まれないように、つる巻ばねの全体を柔軟で無害なゴム類を内部空間に充填すると共に、つる巻ばね全体を柔軟で劣化せず丈夫なしわ付の皮膜薄膜で覆うことで、つる巻ばねの使用感を低減させる。  Fourthly, the entire helical spring is flexible and harmless so that the meat part in the cheeks is not pinched when the helical spring is damaged by any chance or when the gap between the helical springs is opened or closed during use. Is covered with an inner space, and the entire helical spring is covered with a thin film of wrinkles that is flexible and does not deteriorate, thereby reducing the feeling of use of the helical spring.

第５に、つる巻ばねの強さは、口を閉じた時にはやや弱い弾力があって上下の義歯の噛み合いには少し下顎に力を入れる程度とし、大きな力を加えなくても、下顎が少しさげられる程度で、下顎の筋肉に負担をかけない程度の弾性が与えられているようにしておく。  Fifth, the strength of the helical spring is slightly weak when the mouth is closed, and the upper jaw is slightly weaker than the lower jaw. It should be given enough elasticity so that it does not place a burden on the muscles of the lower jaw.

第６に、場合によっては、つる巻ばねと上下の義歯相当との接続部分には、特に、上側の総義歯との接続部分には、下顎の運動にも自然脱落しないような接続装置を設置して臨時の取り外し改良修理もできるようにもして置かなくてはならないので、左右の最先端２線部分５や５′の長さはある程度長くしておき、最奥義歯の外環の内部空間内で２本の最先端部を捻らないで、その１個分前側の義歯の外環内で結んで置けば、少なくても、１度の修理は可能となる。  Sixth, in some cases, a connection device is installed at the connection portion between the helical spring and the upper and lower dentures, especially at the connection portion with the upper complete denture, so that it does not fall off naturally even during mandibular movement. Since it must be placed so that it can be temporarily removed, improved, and repaired, the length of the left and right cutting two-line parts 5 and 5 'should be increased to some extent, and the inner space of the outer ring of the innermost denture At least one repair is possible if the two leading-edge portions are not twisted and tied within the outer ring of the front denture.

以下に、本考案の実施の形態とその効果を図１〜図３に基づいて説明をする。  Below, embodiment of this invention and its effect are described based on FIGS. 1-3.

図１（ａ）には、本考案の「咬合角頂点分散型上下義歯類の連結ばね体」１略して「連結ばね体」１の、装着予定者の口内に装着前の２重つる巻ばね９やゴム１１が伸長した自然状態時の平面図を示してあり、その両端では、取り外し可能の（左）上最奥義歯外環２と（左）下最奥義歯外環２′とにそれぞれ接続された部分の、対腐蝕性の針金又は比較的小さい周辺の角を丸めてある「連結部８付の平板状の突起部６」と同様な突起部６′とにより、連結ばね体１に接続されてあるが、場合によっては、溶接等による直接連結とすることもある。  FIG. 1 (a) shows a double helical spring of the present invention in which the “joining spring body of occlusal angle distributed type upper and lower dentures” 1 is abbreviated as “connecting spring body” 1 in the mouth of the person who is scheduled to wear. 9 and a plan view in a natural state in which the rubber 11 is extended, and at both ends thereof, a removable (left) uppermost denture outer ring 2 and (left) lowermost innermost denture outer ring 2 'are respectively shown. The connecting spring body 1 is connected to the connecting spring body 1 by a corrugated wire or a protrusion 6 ′ similar to the “flat protrusion 6 with the connecting portion 8” with rounded corners around the connected portion. Although they are connected, in some cases, they may be directly connected by welding or the like.

総入歯の重量はせいぜい２０グラム前後であるが、粘着性の食物を噛むときには，上顎から引き離される力は非常に大きくなるので、連結ばね１の弾性力にはそれらに打ち勝って総入歯が上顎内面から離れないような弾性力が必要であるが、これには個人差もあり、平均的に決めて置くこともでき、実験で段階的な弾性を学会で決めて置くこともできる。  The weight of the total denture is at most about 20 grams, but when chewing on sticky food, the force pulled away from the upper jaw becomes very large, so the elastic force of the connecting spring 1 overcomes them and the total denture is on the inner surface of the upper jaw However, there are individual differences, and this can be determined on average, and it is possible to determine the elasticity in stages at an academic meeting by experiment.

人間の歯は上下共に最奥の番号が８まであり、８番歯は親知らずゆえ、一般的には無視できるので、上顎と下顎との結合部の喉脇壁までの空間が２立方センチ前後ある空間内に、本考案の連結ばね体１を設定するには、技術的には義歯製作程度の繊細な技巧を要するとしても、材量的には大量生産が利用できる可能性があるし、あまり高価ではないので、保険でも適用できるようにすれば、総義歯を使用する人には大きな朗報となる。  The human teeth have a depth of up to 8 in both the upper and lower sides, and since the 8th tooth is ignorant, it is generally negligible, so the space to the throat side wall at the joint between the upper jaw and the lower jaw is around 2 cubic centimeters In order to set the connecting spring body 1 of the present invention in the space, even if it is technically a delicate technique of the production of dentures, there is a possibility that mass production can be used in terms of material quantity, It's not expensive, so if you can apply it for insurance, it's great news for people who use complete dentures.

まだ装着してない本考案の連結ばね体１の両端部には、図１（ａ）、（ｂ）のように、連結部８と８′とが設置してあり、これらは、それぞれ対応する左上と左下の最奥義歯外環２と２′とに接続する。  As shown in FIGS. 1 (a) and 1 (b), connecting portions 8 and 8 'are installed at both ends of the connecting spring body 1 of the present invention which is not yet mounted, and these correspond to each other. Connect to the upper left and lower left innermost denture outer rings 2 and 2 '.

左上下の最奥義歯外環２と２′との、連結ばね体１のある側の面上には、それらの義歯の軸と垂直で連結ばね体１側に、それぞれに突起部６と６′とが直接に溶接してある。  On the surface of the left and uppermost deepest denture outer rings 2 and 2 'on the side where the coupling spring body 1 is located, the projections 6 and 6 are respectively perpendicular to the axis of the denture and on the coupling spring body 1 side. ′ Is welded directly.

前項「００１８」の突起部６と６′に対応した、連結ばね体１の連結部８と８′のそれぞれの、２重のつる巻ばね９のそれぞれの両端が焼きなまされてあって線分状に平行に固定されてある、それぞれの、２ばね先端固定部１５と１５′との間には、突起部６と６′に対応した凹部７と７′とがそれぞれ設置してある。  Corresponding to the protrusions 6 and 6 'of the preceding paragraph "0018", both ends of each of the double helical springs 9 of each of the connecting portions 8 and 8' of the connecting spring body 1 are annealed to form a line. Recesses 7 and 7 'corresponding to the protrusions 6 and 6' are installed between the respective two spring tip fixing parts 15 and 15 ', which are fixed in parallel in a divided manner.

連結ばね体１の構造については、図１（ｂ）の右端の途中分断した箇所に、その内部構成を示したが、その太さについては、断面が円形よりも楕円形の方が、この装置を使用した状況により決められるが、完成させた時点での装着使用状況によって断面の形態は決定されるが、咀嚼の上ではどちらでも良い。  About the structure of the connection spring body 1, the internal structure was shown in the part where the right end of FIG.1 (b) was divided, but about the thickness, the cross section is an ellipse rather than a circle. The shape of the cross section is determined depending on the wearing and usage situation at the time of completion, but it may be either on mastication.

いずれにしても、その連結ばね体１の太さは細いほうが良いが、１億回もの咀嚼に耐えるようにしなければならないので、かなり複雑な構造となっているが、部分的には、省略する事もできる。  In any case, the thickness of the connecting spring body 1 should be thin, but it has to be able to withstand 100 million times of chewing, so it has a fairly complicated structure, but partially omitted You can also do things.

連結ばね体１の構造の主体は、合同な２個のつる巻ばねを重ね合わせた２重つる巻ばね９を骨として、両ばねの内部空間に適当な弾力と柔軟性を有するゴム１１を充填させてから、２重つる巻ばね９の外側面に密着させるように、細い鋼線を網状に編んだ筒袋状にした金網１２を密着させてから、時には代りに布製の袋も使用の可能性もあるが、その上面に、適当な厚さに更に、ゴム１１で覆い、その上から丈夫で適当な感触の良い褶曲性に富んだ薄膜１０で覆う様にしてある。  The main part of the structure of the connecting spring body 1 is a double helical spring 9 formed by superposing two congruent helical springs, and the internal space of both springs is filled with rubber 11 having appropriate elasticity and flexibility. After making the metal mesh 12 in the form of a cylindrical bag made of fine steel wire knitted into a net shape so as to be in close contact with the outer surface of the double helical spring 9, sometimes a cloth bag can be used instead. However, the upper surface of the thin film 10 is further covered with a rubber 11 having an appropriate thickness, and is covered with a thin film 10 that is durable and has an appropriate feel and is highly curved.

連結ばね体１の構造の宿命としては、最奥総義歯の直径に比べて大き過ぎては直接に接続できないので、図１のようにくびれ部１６、１６′を設定して接続の容易を図るが、連結ばね体１自体が細くて済む場合には、そのままで最奥義歯に接続することもできる。  The fate of the structure of the connecting spring body 1 is that it is too large compared to the diameter of the innermost complete denture and cannot be directly connected. Therefore, as shown in FIG. 1, the constricted portions 16 and 16 'are set to facilitate connection. However, when the connecting spring body 1 itself can be thin, it can be connected to the innermost denture as it is.

本考案の連結ばね体１を、使用者に装着する前に、上側の義歯や下側の義歯だけではなく、前項「００１４〜００１９」に記載した様な連結ばね体１の両端に設置の２重つる巻ばね９の左右のばね最先端２線分部５と５′の２本ずつの線分状の先端の２本を、図１（ａ）では左上最奥義歯外環２に明けたばね通し穴４に通し、同様に左下最奥義歯外環２′のばね通し穴にも残りの対の２本を通して、それぞれの対のばね最先端２線分部５あるいは５′を、それぞれの左上最奥義歯材埋部３や同左下最奥義歯材埋部３′の空所内で対のばね最先端２線分部５又は５′をそれぞれ捻り合わせるか、後日の再調整用として修理する場合を考えての、これも未装着の、最奥義歯の１個前側の義歯の空間内でそのような操作をするとかして、できれば左下最奥義歯にも同様な操作をするかした後に、本考案の連結ばね体１を取り付けた左上最奥義歯の総入歯の定位置に設置固定し、装着補正してから、残りの左下最奥義歯外環２′を仮取り付け後に本取り付けをする等の、状況により自由に設置と装着を歯科医師の判断で実施し、完成させる。  Before attaching the connecting spring body 1 of the present invention to the user, not only the upper denture and the lower denture, but also two connecting spring bodies 1 installed at both ends of the connecting spring body 1 as described in the previous section “0014-0019”. A spring in which two of the two distal ends of the right and left spring leading two line segments 5 and 5 'of the heavy helical spring 9 are opened in the upper left innermost denture outer ring 2 in FIG. The remaining two pairs are also passed through the through holes 4 and similarly through the remaining two through the spring through holes of the lower left innermost denture outer ring 2 '. When twisting the pair of two most advanced spring line segments 5 or 5 'in the space of the innermost denture material buried portion 3 or the lower left innermost denture material buried portion 3', or repairing for later readjustment If you do such an operation in the space of the denture on the front side of the deepest denture, which is also not attached, if possible, left After performing the same operation on the innermost denture, install and fix it at the fixed position of the upper left innermost denture with the connecting spring body 1 of the present invention attached, correct the attachment, and then adjust the remaining lowermost innermost Depending on the situation, installation and installation can be carried out at the discretion of the dentist, such as mounting the denture outer ring 2 'temporarily after permanent attachment.

咬合状況の左側面閉口図を図２に示し、左側面開口図を図３に示したが、この時の下顎代表線２１の「下顎回転軸○」２３は、その位置が下顎が動くと変化するので、咬合角頂点が分散するとして、本考案の名称も「咬合角頂点分散型」と名称付けしたが、その他の意味はない。  FIG. 2 shows a left side closed view of the occlusal situation, and FIG. 3 shows a left side open view. At this time, the “mandibular rotation axis ○” 23 of the lower jaw representative line 21 changes when the lower jaw moves. Therefore, although the occlusal angle vertices are dispersed, the name of the present invention is also named “occluded angle vertex distributed type”, but there is no other meaning.

図２で、上義歯２と下義歯２′とが閉じている場合には、連結ばね１の弾力は最大であり、図２の噛み合い時上顎押上げ力の作用を表わした矢印２７が大きい矢印で示してあるが、餅等の粘性が強い食物が上義歯に付着した時に、下顎を図３の様にその下方へ下ろすと、その時の連結ばね１の作用が小さくなるが、それが図示された開口時上顎押上げ力の作用を表わした矢印２５よりも小さければ上総義歯は外れないが、大きければ本装置の効果は消失して総入歯が外れてしまう。  In FIG. 2, when the upper denture 2 and the lower denture 2 ′ are closed, the elasticity of the connecting spring 1 is maximum, and the arrow 27 representing the action of the upper jaw pushing force at the time of meshing in FIG. As shown in Fig. 3, when food with strong viscosity such as sputum adheres to the upper denture, if the lower jaw is lowered downward as shown in Fig. 3, the action of the connecting spring 1 at that time becomes smaller, but this is illustrated. If the upper denture is smaller than the arrow 25 representing the action of the upper jaw pushing force at the time of opening, the upper complete denture cannot be removed, but if it is larger, the effect of the apparatus is lost and the total denture is removed.

従って、前項「００２６」の矢印２５が、餅等の引力に打ち勝つ程度に、２重つる巻ばね９の弾性を強力にするが、その場合には、閉口時の閉じた口が自然に開かれてしまう可能性が生じるが、連結ばね体１の実用的な弾力の物が各種製作してあれば、実施時までに希望通りに自由に決めさせるようにできることから、希望に応じた連結ばね体１についての装着者の不満からの、トラブルは回避可能である。  Accordingly, the arrow 25 in the preceding item “0026” strengthens the elasticity of the double helical spring 9 to such an extent that it can overcome the attractive force of the hook or the like, but in that case, the closed mouth when closed is naturally opened. However, if a variety of practically elastic springs of the connecting spring body 1 can be manufactured, the connecting spring body can be freely determined as desired by the time of implementation. Troubles caused by wearer dissatisfaction about 1 can be avoided.

上述したように本考案の、咬合角頂点分散型上下義歯類の連結ばね体略して、連結ばね体の製作には、つる巻ばね工業、特殊鋼工業、不錆鋼工業、ゴム工業、特殊金網工業、金属結合工業、特殊ビニール工業、等の多岐に関連している。  As described above, the connecting spring body of the occlusal angle distributed type upper and lower dentures of the present invention is abbreviated, and the connecting spring body is manufactured by the helical spring industry, special steel industry, non-rust steel industry, rubber industry, special wire mesh. It is related to various fields such as industry, metal bonding industry, and special vinyl industry.

しかも、高年齢層向きの咬合性の改善が果たせる結果を得られるので、新規の義歯結合業の要望と歯科医師業者の繁栄にも通じる。  In addition, since the results of improvement in occlusion for the elderly can be obtained, it leads to the demand for a new denture coupling business and the prosperity of dentists.

For dentures in situations where the upper and lower dentures are not yet installed, including both dentures at the innermost and lowermost dentures of the complete denture Assuming that a denture is formed only on the side of the outer ring of the metal innermost tooth, it is parallel to the average plane of the pair of upper and lower innermost dentures, and an appropriate distance between the upper and lower sides. At a position equidistant from the assumed center line in the dentition direction on the upper and lower two surfaces away from the gums, a dentition direction line is placed on each outer ring side surface on the upper and lower two surfaces along the dentition direction line. Two small cylindrical holes (4) are made between the two holes of the outer ring pair on the back side such as upper and lower dentures. The fixed protrusions (6) and (6 ') are fixed to the upper and lower outer ring side surfaces by welding or the like perpendicularly to the denture axis, and both the upper and lower parts before attaching to the denture wearer are If it is the left side, on the plane of the workbench, after aligning the dentinal part equivalent side of the innermost denture on the same left side with the top side, and placing the innermost projection part facing each other, Separately, two double helical springs, which are created in advance by mass production, etc., mesh with two anti-corrosive joint helical springs having a certain diameter, length and elasticity. (9) No, the inside space is filled with harmless rubber (11), and the outer periphery of the helical spring is wrapped with a thin and strong metal mesh wire mesh (12) or durable cloth. Wrap and apply rubber to the outside to a suitable thickness, and apply a strong and flexible water-resistant tubular thin film (10) on the top surface. If the length is changed in the length direction of the helical spring, it is placed so that it will not break anywhere, and the ends of the double helical spring may be partially Although the diameter is smaller than the size of both dentures, the upper left most distal part (5) and the lower left most advanced part (5 ') located on the left and right sides thereof are appropriately blunted by heating or the like to form a line segment. Two spring tips fixed with recesses (7) and (7 ') set so that the projections (6) and (6') can be fitted exactly between the two protruding each. The whole completed by the part (15) is a connecting spring body (1), and the two nearest holes at the nearest innermost side of the two oppositely opened innermost dentures are paired. In the two holes on both sides of each protrusion on the inner side, the left and right pairs of spring tips 2 line segments (5) (5 ') is inserted into each straight section, and two pairs of segments are connected in the inner space of the innermost outer ring (2, 2'), etc., and fixed by fixing material or welding, etc. When the device is actually mounted such that the upper left and right innermost dentures are connected by the connecting spring body (1), such as fixing from within the outer ring on the adjacent front side after taking out from the opposite side of Occlusal angle vertex-distributed type upper and lower dentures mainly composed of double helical springs that prevent the upper denture from falling naturally during meals with the same adhesion as when both upper and lower jaws are closed naturally Connecting spring body.
