Abstract

PROBLEM TO BE SOLVED: To provide a rubber dam clamp that reduces discomfort when mounted.SOLUTION: A rubber dam clamp 20 includes: a spring 11 formed with a cutout part 11a so as to be C-shaped substantially, the cutout part 11a being capable of being widened by elastic deformation; and flanges 12 formed at both ends of the spring 11, respectively, and having beaks 23 coming into contact with the side of a tooth crown. The rubber dam clamp fixes a rubber dam sheet placed on the teeth to expose the tooth crown T by clamping the exposed tooth crown T with the pair of beaks 23. The beaks 23 are configured so that an irregular shape of an abutment portion with the tooth crown T is formed in conformity to the shape of the tooth crown T of a patient and a wall thickness is formed substantially equally with the height of the tooth crown T of the patient. When the tooth crown T is clamped, the beaks 23 are brought into surface contact with the side faces of the tooth crown T from the upper end to the lower end.

Description

本発明は、歯冠を一対のビークで挟持することでラバーダムシートを固定するラバーダムクランプに関するものである。   The present invention relates to a rubber dam clamp that fixes a rubber dam seat by sandwiching a crown between a pair of beaks.

歯の治療は広義の外科的処置であるので、多数の菌が存在する唾液が治療中の患部に触れることは当然好ましくない。また、患部に唾液が付着すると治療の作業効率も低下してしまう。
さらに、治療中に患者の舌が動いてしまい、治療の妨げになることも多い。
Since the treatment of teeth is a surgical procedure in a broad sense, it is naturally not preferable that saliva containing a large number of bacteria touches the affected area being treated. In addition, if saliva adheres to the affected area, the work efficiency of the treatment also decreases.
In addition, the patient's tongue may move during treatment, often hindering treatment.

そこで、治療対象の歯冠を口腔内の他の部位と隔絶するためにラバーダムシートが用いられている。
ラバーダムシートは、治療対象の歯冠がラバーダムシートの表側に露出し、口腔内の他の部位(舌や歯茎、他の歯冠)はラバーダムシートの裏側となるように、歯冠に被せられる。
そして、このラバーダムシートを固定するために、図7及び図8に示すようなラバーダムクランプが開示されている(例えば、特許文献1参照)。
Therefore, a rubber dam sheet is used to isolate the dental crown to be treated from other parts in the oral cavity.
The rubber dam sheet is placed on the crown so that the dental crown to be treated is exposed on the front side of the rubber dam sheet, and other parts (the tongue, gums, and other crowns) in the oral cavity are on the back side of the rubber dam sheet.
And in order to fix this rubber dam sheet | seat, the rubber dam clamp as shown in FIG.7 and FIG.8 is disclosed (for example, refer patent document 1).

特公昭63−13702号公報Japanese Patent Publication No. 63-13702

図7及び図8に記載の発明は、略C字状のスプリング11と、歯冠側面に当接するビーク13を有するフランジ12とを備える。
ビーク13は一対のフランジ12の内側端部のことであり、ビーク13の肉厚はフランジ12の肉厚に等しい。
また、それぞれのビーク13は円弧状となっており、一対のビーク13が向かい合うことによって略円形が形成される。
そして、歯冠が露出するようにラバーダムシートが被せられ、露出した歯冠の下端(歯茎に近い部分)を一対のビーク13が挟持することでラバーダムシートを固定するものである。
The invention described in FIGS. 7 and 8 includes a substantially C-shaped spring 11 and a flange 12 having a beak 13 in contact with the side surface of the crown.
The beak 13 is an inner end portion of the pair of flanges 12, and the thickness of the beak 13 is equal to the thickness of the flange 12.
Each beak 13 has an arc shape, and a pair of beaks 13 face each other to form a substantially circular shape.
And a rubber dam sheet | seat is covered so that a dental crown may be exposed, and a rubber dam sheet | seat is fixed by pinching the lower end (part close | similar to a gum) of the exposed dental crown between a pair of beaks 13. FIG.

この発明によると、歯茎と歯冠の境界部分である歯冠の下端をビーク13が挟持するので、歯冠が完全に露出した状態でラバーダムシートをしっかり固定することができる。   According to the present invention, the beak 13 holds the lower end of the crown, which is the boundary between the gum and the crown, so that the rubber dam sheet can be firmly fixed with the crown fully exposed.

しかしながら、このラバーダムクランプ10は歯冠の下端をビーク13が挟持できるようにビーク13の歯冠側面に当接する部分が線状となっているので、装着時には挟持する圧力が歯冠の下端に集中して掛かってしまう。
したがって、ラバーダムクランプ10の装着時に歯冠下端や歯茎に痛みを感じる患者も存在して、必ずしも快適な付け心地であるとはいえなかった。
However, since the rubber dam clamp 10 has a linear portion in contact with the side surface of the crown of the beak 13 so that the lower end of the crown can be pinched by the beak 13, the pressure to be pinched at the time of mounting is concentrated on the lower end of the crown. Then it will hang.
Therefore, there is a patient who feels pain in the lower end of the crown and the gums when the rubber dam clamp 10 is mounted, and it cannot be said that it is always a comfortable wearing feeling.

そこで、本発明の目的とするところは、装着時の不快感が低減されたラバーダムクランプを提供することにある。   Accordingly, an object of the present invention is to provide a rubber dam clamp with reduced discomfort during mounting.

上記の目的を達成するために、本発明の請求項1に記載のラバーダムクランプ(20)は、略C字状となるように切欠部(11a)が形成され弾性変形によって前記切欠部(11a)の幅を拡開可能なスプリング(11)と、前記スプリング(11)の両端部にそれぞれ形成されるとともに歯冠(T)側面に当接するビーク(23)を有するフランジ(12)と、を備え、前記歯冠(T)が露出するように被せられるラバーダムシートを、前記露出した歯冠(T)を一対の前記ビーク(23)で挟持することで固定するラバーダムクランプ(20)において、前記ビーク(23)が前記歯冠(T)側面の少なくとも上部及び下部に当接した状態で前記歯冠(T)を挟持することを特徴とする。   In order to achieve the above object, the rubber dam clamp (20) according to claim 1 of the present invention has a notch (11a) formed so as to be substantially C-shaped, and the notch (11a) is formed by elastic deformation. And a flange (12) having beaks (23) formed at both ends of the spring (11) and in contact with the side surface of the crown (T). In the rubber dam clamp (20) for fixing the rubber dam sheet, which is covered so that the crown (T) is exposed, by sandwiching the exposed crown (T) by a pair of the beaks (23), the beak (23) is characterized in that the crown (T) is sandwiched in a state of being in contact with at least an upper part and a lower part of the side surface of the crown (T).

また、請求項2に記載のラバーダムクランプ(20)は、前記ビーク(23)は、前記歯冠(T)との当接部分が前記歯冠(T)を包み込むように互いに離間する方向に湾曲して形成されるとともに肉厚が前記患者の歯冠(T)の高さと略等しく形成され、前記歯冠(T)を挟持したときに前記ビーク(23)が前記歯冠(T)側面の上部から下部まで面で当接するようにしたことを特徴とする。   The rubber dam clamp (20) according to claim 2, wherein the beak (23) is bent in a direction in which the abutting portion with the crown (T) is separated from each other so as to wrap the crown (T). And the wall thickness is substantially equal to the height of the patient's crown (T). When the crown (T) is sandwiched, the beak (23) is formed on the side surface of the crown (T). It is characterized by being in contact with the surface from the upper part to the lower part.

また、請求項3に記載のラバーダムクランプ(20)は、前記ビーク(23)は、前記歯冠(T)との当接部分の凹凸形状が患者の歯冠(T)の形状に合わせて形成されるとともに肉厚が前記患者の歯冠(T)の高さと略等しく形成され、前記歯冠(T)を挟持したときに前記ビーク(23)が前記歯冠(T)側面の上部から下部まで面で当接することを特徴とする。   Further, in the rubber dam clamp (20) according to claim 3, the beak (23) is formed so that the concavo-convex shape of the contact portion with the crown (T) matches the shape of the patient's crown (T). And the wall thickness is formed to be substantially equal to the height of the patient's crown (T), and when the crown (T) is sandwiched, the beak (23) is lowered from the upper side to the lower side of the side surface of the crown (T). It is characterized by abutting on the surface.

また、請求項4に記載のラバーダムクランプ(20)は、前記ビーク(23)は、樹脂で形成されるとともに肉厚が患者の歯冠(T)の高さと略等しく形成され、前記歯冠(T)を挟持したときに前記ビーク(23)が変形して前記歯冠(T)側面の上部から下部まで面で当接することを特徴とする。
なお、ここでいう下とは歯に対して歯茎側をいい、上とは歯の噛み合わせ部分側をいう。したがって、下顎の歯においては通常の上下方向と一致するが、一方、上顎の歯においては通常の上下方向とは逆となる。
The rubber dam clamp (20) according to claim 4, wherein the beak (23) is formed of a resin and has a thickness substantially equal to a height of a patient's crown (T). When the T) is clamped, the beak (23) is deformed and comes into contact with the surface from the upper part to the lower part of the side surface of the crown (T).
Here, “lower” refers to the gum side with respect to the teeth, and “upper” refers to the meshing portion side of the teeth. Therefore, it corresponds to the normal vertical direction in the lower teeth, whereas it is opposite to the normal vertical direction in the upper teeth.

ここで、上記括弧内の記号は、図面および後述する発明を実施するための形態に掲載された対応要素または対応事項を示す。   Here, the symbols in the parentheses indicate corresponding elements or corresponding matters described in the drawings and embodiments for carrying out the invention described later.

本発明の請求項1に記載のラバーダムクランプによれば、ビークが歯冠側面の少なくとも上部及び下部に当接した状態で歯冠を挟持するので、ビークが歯冠側面の下端のみを挟持する場合に比べて圧力が分散される。よって、歯冠側面を挟持する圧力が低いので、装着時に患者の不快感が低減される。   According to the rubber dam clamp according to claim 1 of the present invention, the beak clamps the crown in a state in which the beak is in contact with at least the upper part and the lower part of the crown side surface, and therefore the beak clamps only the lower end of the crown side surface. The pressure is distributed compared to. Therefore, since the pressure which clamps a dental crown side surface is low, a patient's discomfort at the time of mounting | wearing is reduced.

また、請求項2に記載のラバーダムクランプによれば、請求項1に記載の発明の作用効果に加え、ビークは、歯冠との当接部分が歯冠を包み込むように互いに離間する方向に湾曲して形成されるとともに肉厚が患者の歯冠の高さと略等しく形成したので、歯冠を挟持したときにビークが歯冠側面の上部から下部まで面で当接する。よって、歯冠側面を挟持する圧力がさらに低いので、装着時に患者の不快感が低減される。   According to the rubber dam clamp of the second aspect, in addition to the function and effect of the invention of the first aspect, the beak is curved in a direction away from each other so that a contact portion with the crown wraps around the crown. Since the thickness of the crown is substantially equal to the height of the patient's crown, the beak abuts on the surface from the top to the bottom of the side surface of the crown when the crown is sandwiched. Therefore, since the pressure which clamps a dental crown side surface is still lower, a patient's discomfort at the time of mounting | wearing is reduced.

また、請求項3に記載のラバーダムクランプによれば、請求項1又は2に記載の発明の作用効果に加え、ビークは、歯冠との当接部分の凹凸形状が患者の歯冠の形状に合わせて形成されるとともに肉厚が患者の歯冠の高さと略等しく形成されるので、歯冠を挟持したときにビークが歯冠側面の上部から下部まで確実に面で当接する。よって、さらに装着時の不快感が低減される。   According to the rubber dam clamp of the third aspect, in addition to the function and effect of the invention of the first or second aspect, the beak has an uneven shape of a contact portion with the crown so that the shape of the patient's crown is obtained. Since they are formed together and the thickness is substantially equal to the height of the patient's crown, when the crown is sandwiched, the beak reliably abuts on the surface from the top to the bottom of the side surface of the crown. Therefore, discomfort at the time of wearing is further reduced.

また、請求項4に記載のラバーダムクランプによれば、請求項1又は2に記載の発明の作用効果に加え、ビークは、樹脂で形成されるとともに肉厚が患者の歯冠の高さと略等しく形成され、歯冠を挟持したときにビークが変形して歯冠側面の上部から下部まで面で当接するので、ビークを患者の歯冠の形状に合わせて形成しなくても、装着時の不快感は少ない。   According to the rubber dam clamp of the fourth aspect, in addition to the function and effect of the invention of the first or second aspect, the beak is formed of resin and has a thickness substantially equal to the height of the patient's crown. The beak is deformed when the crown is pinched and abuts on the surface from the top to the bottom of the side surface of the crown, so even if the beak is not formed to match the shape of the patient's crown, There is little pleasure.

なお、本発明のラバーダムクランプのように、ビークが歯冠側面の少なくとも上部及び下部に当接した状態で歯冠を挟持する点は、上述した特許文献1には全く記載されていない。   In addition, the point which pinches a crown in the state which the beak contact | abutted to at least the upper part and lower part of the crown side surface like the rubber dam clamp of this invention is not described at all in the patent document 1 mentioned above.

図1乃至図5を参照して、本発明の実施形態に係るラバーダムクランプ20を説明する。
このラバーダムクランプ20は、スプリング11と、ビーク23を有するフランジ12を備え、特にビーク23の形状に特徴がある。
本実施形態に係るラバーダムクランプ20は、最も奥の歯冠T一つに対して挟持するように装着され、その歯冠Tが露出するように被せられたラバーダムシート(図示しない)を固定するものである。
従来例で示したものと同一部分には同一符号を付した。
なお、図4及び図5では簡単のためにラバーダムシートを省略しているが、通常歯茎Gはラバーダムシートに覆われており視認できない。
With reference to FIG. 1 thru | or FIG. 5, the rubber dam clamp 20 which concerns on embodiment of this invention is demonstrated.
The rubber dam clamp 20 includes a spring 11 and a flange 12 having a beak 23, and is particularly characterized by the shape of the beak 23.
The rubber dam clamp 20 according to the present embodiment is mounted so as to be clamped with respect to one innermost crown T, and fixes a rubber dam sheet (not shown) that is covered so that the crown T is exposed. It is.
The same parts as those shown in the conventional example are denoted by the same reference numerals.
4 and 5, the rubber dam sheet is omitted for simplicity, but the gum G is usually covered with the rubber dam sheet and cannot be visually recognized.

スプリング11は、幅の狭い金属帯が湾曲してなり、それが略C字状となるように切欠部11aが形成されている。つまり、「C」という文字における切れた部分が切欠部11aである。
その切欠部11aの幅は治療対象の歯冠Tの幅と略等しく、弾性変形によって切欠部11aの幅を拡開可能である。よって、切欠部11aの幅を拡開させてもその力を取り去ると、切欠部11aの幅は元通り狭くなる。
The spring 11 is formed with a notch 11a so that a narrow metal band is curved and is substantially C-shaped. That is, the cut portion of the character “C” is the cutout portion 11a.
The width of the notch 11a is substantially equal to the width of the crown T to be treated, and the width of the notch 11a can be expanded by elastic deformation. Therefore, even if the width of the notch portion 11a is expanded, if the force is removed, the width of the notch portion 11a is reduced to the original.

フランジ12は、図2に示すように山折りされた板状で、スプリング11の両端部であってスプリング11の幅方向に関してそれぞれ同じ側(例えば図1においては下側)に突出するように一対形成される。
よって、図1に示すように平面視においてフランジ12はスプリング11とは重なっていない。
As shown in FIG. 2, the flange 12 has a plate shape that is folded in a mountain shape, and is a pair of both ends of the spring 11 so as to protrude to the same side (for example, the lower side in FIG. 1) in the width direction of the spring 11. It is formed.
Therefore, as shown in FIG. 1, the flange 12 does not overlap the spring 11 in plan view.

また、それぞれのフランジ12の内側端部には、互いに向かい合い歯冠Tへの装着時には歯冠T側面に当接するビーク23を有する。
また、それぞれのフランジ12のスプリング11近傍には孔12aが形成されている。この孔12aには拡開治具(図示しない)を挿入可能であって、ラバーダムクランプ20を歯冠Tへ装着するときには、拡開治具によってスプリング11の切欠部11aの幅が一時的に広げられる。
In addition, the inner ends of the flanges 12 have beaks 23 that face each other and come into contact with the side surface of the crown T when mounted on the crown T.
A hole 12 a is formed in the vicinity of the spring 11 of each flange 12. An expansion jig (not shown) can be inserted into the hole 12a, and when the rubber dam clamp 20 is attached to the crown T, the width of the notch 11a of the spring 11 is temporarily expanded by the expansion jig. It is done.

ビーク23は、歯冠Tとの当接部分が歯冠Tを包み込むように互いに離間する方向に湾曲して形成され、ラバーダムクランプ20装着時にはビーク23は歯冠T側面に両側から当接する。
しかも、ビーク23の歯冠Tとの当接部分の凹凸形状はそれぞれの患者の歯冠Tの形状に合わせて形成されている。よって、一方のビーク23と他方のビーク23は互いに異なる形状となっている。
また、一人の患者用のラバーダムクランプ20であっても装着する歯冠Tが異なれば、ビーク23の形状もそれぞれ異なるように形成される。
このように、患者の歯冠Tの形状に合わせてカスタマイズしてビーク23を一つ一つ形成する方法としては、本実施形態においては患者の歯型を取ってロストワックス法を用いた。
The beak 23 is formed so as to be curved away from each other so that the contact portion with the crown T wraps around the crown T. When the rubber dam clamp 20 is mounted, the beak 23 contacts the side surface of the crown T from both sides.
Moreover, the uneven shape of the contact portion of the beak 23 with the crown T is formed in accordance with the shape of the crown T of each patient. Therefore, one beak 23 and the other beak 23 have different shapes.
Moreover, even if it is the rubber dam clamp 20 for one patient, if the crown T to mount | wear differs, the shape of the beak 23 will also differ, respectively.
As described above, as a method for forming the beaks 23 one by one according to the shape of the crown T of the patient, the lost wax method is used by taking the patient's tooth shape in this embodiment.

またビーク23の肉厚は、フランジ12の肉厚よりも厚く、患者の歯冠Tの高さと略等しく形成されている。
したがって、歯冠Tを挟持したときにはビーク23が歯冠T側面の上端から下端まで面で当接する。
ここで、ラバーダムクランプ20装着時にフランジ12が歯冠Tの高さ略中央となるように、ビーク23の肉厚の略中央にフランジ12が接続されている。
このフランジ12及びビーク23はスプリングと同様に金属製である。
Further, the thickness of the beak 23 is thicker than the thickness of the flange 12 and is substantially equal to the height of the patient's crown T.
Therefore, when the crown T is sandwiched, the beak 23 abuts on the surface from the upper end to the lower end of the side surface of the crown T.
Here, the flange 12 is connected to the approximate center of the wall thickness of the beak 23 so that the flange 12 is approximately the center of the height of the crown T when the rubber dam clamp 20 is mounted.
The flange 12 and the beak 23 are made of metal like the spring.

以上のように構成されたバーダムクランプ20の一対のビーク23でラバーダムシートから露出した歯冠Tを挟持して、ラバーダムシートを固定する。   The rubber dam sheet is fixed by holding the crown T exposed from the rubber dam sheet between the pair of beaks 23 of the bar dam clamp 20 configured as described above.

本実施形態に係るラバーダムクランプ20によれば、ビーク23は、歯冠Tとの当接部分の凹凸形状が患者の歯冠Tの形状に合わせて形成されるとともに肉厚が患者の歯冠Tの高さと略等しく形成されるので、歯冠Tを挟持したときにビーク23が歯冠T側面の上端から下端まで確実に面で当接する。よって、歯冠T側面を挟持する圧力が分散されて低いので、装着時の患者の不快感が低減される。   According to the rubber dam clamp 20 according to the present embodiment, the beak 23 is formed so that the concave-convex shape of the contact portion with the crown T matches the shape of the patient's crown T, and the thickness of the beak 23 is the patient's crown T. Therefore, when the crown T is sandwiched, the beak 23 reliably comes into contact with the surface from the upper end to the lower end of the side surface of the crown T. Therefore, since the pressure which pinches | interposes the crown T side surface is disperse | distributed and low, the discomfort of the patient at the time of mounting | wearing is reduced.

なお、本実施形態において、ビーク23の歯冠Tとの当接部分の凹凸形状が患者の歯冠Tの形状に合わせて形成されたが、これに限られるものではなく、単に歯冠Tを包み込むように互いに離間する方向に湾曲して形成されていてもよい。すなわち、歯冠Tを挟持したときにビーク23が歯冠T側面の上部から下部までおおよそ面で当接すれば、患者一人一人に合わせた形状でなくてもよい。   In the present embodiment, the uneven shape of the contact portion of the beak 23 with the crown T is formed to match the shape of the patient's crown T. However, the present invention is not limited to this. It may be formed so as to be bent in a direction away from each other so as to be wrapped. In other words, if the beak 23 abuts on the surface from the upper part to the lower part of the side surface of the crown T when the crown T is sandwiched, the shape may not be suitable for each patient.

その他、ビーク23は、例えばポリ塩化ビニル,シリコーンゴム,熱可塑性エラストマー等の軟質樹脂で形成されていてもよい。この場合、ビーク23が患者一人一人の歯冠Tの形状に合わせて形成されていなくても、歯冠Tを挟持したときにビーク23が変形して歯冠T側面の上部から下部まで面で当接するので、装着時の不快感は少ない。   In addition, the beak 23 may be made of a soft resin such as polyvinyl chloride, silicone rubber, or thermoplastic elastomer. In this case, even if the beak 23 is not formed in conformity with the shape of the crown T of each patient, the beak 23 is deformed when the crown T is sandwiched, and the surface extends from the top to the bottom of the side surface of the crown T. Since it abuts, there is little discomfort at the time of wearing.

また、ビーク23が歯冠T側面の上端から下端まで面で当接するとしたが、これに限られるものではなく、上部から下部まで面で当接すればよい。   Moreover, although the beak 23 contact | abutted by the surface from the upper end of the crown T side surface to a lower end, it is not restricted to this, What is necessary is just to contact | abut by the surface from the upper part to the lower part.

さらには、図6に示すように、ビーク23の形状がそれぞれ上下に二又に分かれて、装着時には歯冠T側面の上部及び下部に当接した状態で歯冠Tを挟持してもよい。
このようにビーク23が面で歯冠T側面に当接していなくても、従来例のように歯冠T側面の下端のみに当接するビーク13を有するものよりは挟持圧力が低減しているので、従来のラバーダムクランプ10よりは装着時に不快ではない。
Furthermore, as shown in FIG. 6, the shape of the beak 23 may be divided into two in the upper and lower directions, and the crown T may be sandwiched in contact with the upper and lower portions of the side surface of the crown T at the time of mounting.
Thus, even if the beak 23 is not in contact with the crown T side surface by the surface, the clamping pressure is reduced as compared with the conventional example having the beak 13 contacting only the lower end of the crown T side surface. The conventional rubber dam clamp 10 is not uncomfortable when worn.

また、このラバーダムクランプ20は最も奥の歯に装着するとしたが、これに限られるものではなく、必要に応じて他の歯に装着可能な形状のビーク23を有するラバーダムクランプ20としてもよい。   In addition, the rubber dam clamp 20 is attached to the innermost tooth, but is not limited thereto, and may be a rubber dam clamp 20 having a beak 23 having a shape that can be attached to other teeth as necessary.

なお、ここでいう下とは歯に対して歯茎側をいい、上とは歯の噛み合わせ部分側をいう。したがって、下顎の歯においては通常の上下方向と一致するが、一方、上顎の歯においては通常の上下方向とは逆となる。 Incidentally, refer to gingival against teeth and lower as used herein means a partial side engagement of teeth as above. Therefore, it corresponds to the normal vertical direction in the lower teeth, whereas it is opposite to the normal vertical direction in the upper teeth.

本発明によれば、ビークが歯冠側面の少なくとも上部及び下部に当接した状態で歯冠を挟持するので、ビークが歯冠側面の下端のみを挟持する場合に比べて圧力が分散される。よって、歯冠側面を挟持する圧力が低いので、装着時に患者の不快感が低減される。 According to the present invention, the crown is sandwiched in a state where the beak is in contact with at least the upper part and the lower part of the side surface of the crown, so that the pressure is distributed compared to the case where the beak sandwiches only the lower end of the side surface of the crown. Therefore, since the pressure which clamps a dental crown side surface is low, a patient's discomfort at the time of mounting | wearing is reduced.

また、本発明によれば、ビークは、歯冠との当接部分の凹凸形状が患者の歯冠の形状に合わせて形成されるとともに肉厚が患者の歯冠の高さと略等しく形成されるので、歯冠を挟持したときにビークが歯冠側面の上部から下部まで確実に面で当接する。よって、さらに装着時の不快感が低減される。 According to the present invention, the beak is formed such that the concave-convex shape of the contact portion with the crown is matched to the shape of the patient's crown and the wall thickness is substantially equal to the height of the patient's crown. Therefore, when the crown is sandwiched, the beak comes into contact with the surface reliably from the top to the bottom of the side surface of the crown. Therefore, discomfort at the time of wearing is further reduced.
