Description

筋肉位３Ｄ調節器具及び人工歯Muscle position 3D adjusting device and artificial teeth
　本発明は、顎位を失った患者の中心位と中心咬合位を一致させる治療で用いられる筋肉位３Ｄ調節器具に関する。特に、総義歯、臼歯部欠損の部分床義歯の作製に際して用いられる筋肉位３Ｄ調節器具に関する。さらに、顎位の調整を必要とする他の疾患の治療に用いる器具に関する。 The present invention relates to a muscular position 3D adjusting device used in treatment for matching the central position and the central occlusal position of a patient who has lost his / her jaw position. In particular, the present invention relates to a muscular position 3D adjusting device used in the production of a partial denture having a complete denture and a missing molar portion. Furthermore, the present invention relates to a device used for the treatment of other diseases requiring adjustment of the jaw position.
　顎位を失った患者の中心位と中心咬合位を一致させる治療で、代表的な治療は総義歯治療である。本発明の筋肉位３Ｄ器具は総義歯治療の作製に限らず、部分床義歯の作製にも用いることができるが、ここでは代表的な治療である総義歯治療を中心に以下説明する。 A treatment that matches the central position and the central occlusal position of a patient who has lost his / her jaw position. A typical treatment is denture treatment. The muscular position 3D device of the present invention can be used not only for the production of a complete denture treatment but also for the production of a partial denture, but here, a typical denture treatment, which is a typical treatment, will be described below.
　ここで、顎位とは、上顎に対しての下顎の三次元的な位置を指し、咀嚼時に必要な上下顎の接触位置関係を定めたものである。上顎骨は頭骸骨の一部であるため位置が固定されるのに対して、下顎骨は左右に顎関節があり垂直に移動するだけではなく水平方向にも移動する。また、中心位の定義には諸説あるため、ここでは「中心位をタッピングポイント・中心咬合位をアペックススタート位置」また、「顆頭安定位＝中心位」と仮定する。 Here, the jaw position refers to the three-dimensional position of the lower jaw with respect to the upper jaw, and defines the contact position relationship between the upper and lower jaws necessary for mastication. Since the maxilla is a part of the skull, the position is fixed, while the mandible has temporomandibular joints on the left and right and moves not only vertically but also horizontally. Since there are various theories on the definition of the central position, it is assumed here that “the central position is the tapping point and the central occlusal position is the apex start position” and “condylar head stable position = central position”.
　総義歯治療では、顎関節と神経筋機構とが調和した状態で下顎歯列と上顎歯列とが安定して噛み合うように、上顎位に対する下顎位を最適化することが求められる。総義歯治療は、術者の技術、経験、感覚等に依存する割合が多いため、下顎の位置合わせが困難であり、総義歯作製に多くの手間と時間を要する。しかし、下顎の位置合わせは、治療結果を大きく左右するポイントになる。また、前歯等が一部残存している患者においても、患者は顎位を失っており、その中心位と中心咬合位を一致させることは総義歯同様に重要である。 In complete denture treatment, it is required to optimize the lower jaw position with respect to the upper jaw position so that the lower jaw dentition and upper jaw dentition are stably meshed with the temporomandibular joint and the neuromuscular mechanism in harmony. Complete denture treatment is highly dependent on the skill, experience, and sensation of the operator, making it difficult to position the lower jaw, and it takes a lot of time and effort to make a complete denture. However, the alignment of the lower jaw is a point that greatly affects the treatment result. Further, even in a patient in which some of the front teeth remain, the patient has lost the jaw position, and it is as important as the complete denture to make the center position coincide with the central occlusal position.
　顎位の調整、中心位と中心咬合位が一致するような安定した咀嚼を得るために、一般的にはパラフィンワックスを用いた咬合床による咬合採得法が行われている。しかし、パラフィンワックスの軟化温度により不均一性が生じることから、ワックスによって下顎頭が誘導される可能性がある。また、ワックスは温度が下がると接触したまま硬化するため、接触面の誘導位置から顆頭が安定位に移動することができない。 In order to adjust the jaw position and obtain a stable mastication in which the central position matches the central occlusal position, generally, an occlusal acquisition method using an occlusal floor using paraffin wax is performed. However, since the non-uniformity is caused by the softening temperature of the paraffin wax, there is a possibility that the mandibular head is induced by the wax. Further, since the wax hardens while being in contact with the temperature as the temperature decreases, the condyle cannot move to the stable position from the guide position of the contact surface.
　また、従来、総義歯の作製に際して咬合採得に用いられる筋肉位を三次元的に調整する器具（以下、筋肉位３Ｄ調節器具という。）として、上顎に適合する上顎基礎床の左右臼歯部に描記ブレードを設けるとともに、下顎に適合する下顎基礎床の左右臼歯部に、前記描記ブレードの先端面が当接する記録ブロックを設け、これらを口腔内に装着した状態で、記録ブロック又は描記ブレードの全体高さ及び左右高さを調節することにより、上顎位に対する下顎位を記録するものが知られている（例えば特許文献１参照）。 Conventionally, as a device for three-dimensionally adjusting the muscle position used for occlusal acquisition in the preparation of a complete denture (hereinafter referred to as a muscle position 3D adjustment device), the left and right molar portions of the upper base floor that fit the upper jaw are used. In addition to providing a drawing blade, the left and right molars of the lower mandibular basement that fits the lower jaw are provided with a recording block against which the tip surface of the drawing blade comes into contact. One that records the lower jaw position relative to the upper jaw position by adjusting the height and the left and right height is known (see, for example, Patent Document 1).
　特許文献１記載の器具は、歯科技工士によって、咬合器に装着された患者の上下顎作業用模型に上下顎基礎床が装着された状態で、描記ブレードと記録ブロックとが互いに対向するように上顎基礎床及び下顎基礎床の左右臼歯部に取り付けられる。 The instrument described in Patent Document 1 is such that the drawing blade and the recording block face each other in a state where the upper and lower jaw base floor is attached to the patient's upper and lower jaw working model attached to the articulator by the dental technician. It is attached to the left and right molar parts of the upper and lower mandibular floors.
　次に、歯科医師によって、前記器具は上下顎基礎床に取り付けられた状態で患者の口腔内に装着され、咬合採得が行われる。このとき、描記ブレード及び記録ブロックの接触面において全体の高さが高すぎず低すぎず、左右が均等に接触するように、前記器具は、患者の口腔から取り出されて、記録ブロックが削合されたり記録ブロックにレジンが盛り足された後、患者の口腔内に再装着される。そして、記録ブロックの上面に咬合位記録材を塗布して咬合させ、描記ブレードが当接した跡が凹凸として記録される。 Next, the dentist attaches the instrument to the patient's oral cavity in a state of being attached to the upper and lower jaw base floor, and performs occlusal acquisition. At this time, the device is removed from the patient's mouth so that the entire height of the contact surface of the drawing blade and the recording block is not too high and not too low, and the left and right are in contact with each other. Or after the resin has been added to the recording block, it is remounted in the patient's mouth. Then, an occlusal recording material is applied to the upper surface of the recording block to be engaged, and the trace of contact of the drawing blade is recorded as unevenness.
　次に、前記器具は上下顎基礎床に取り付けられた状態で患者の口腔から取り出された後、歯科技工士によって、咬合器に固定された上下顎作業用模型に再装着される。このとき、口腔内で記録した状態に上下顎基礎床を咬合させて、上下顎作業用模型に再装着される。そして、歯科技工士によって、上下顎作業用模型に装着された上下顎基礎床において蝋義歯が作られた後、歯科医師によって、前記蝋義歯が患者の口腔に装着されて、歯並び、咬み合わせ、顎の位置等が確認された後、歯科技工士によって最終義歯が作られる。 Next, the device is removed from the oral cavity of the patient while attached to the upper and lower jaw base floor, and then reattached to the upper and lower jaw working model fixed to the articulator by the dental technician. At this time, the base of the upper and lower jaws is occluded in the state recorded in the oral cavity, and is remounted on the upper and lower jaw working model. And, after a dental technician makes a wax denture on the upper and lower jaw base floor attached to the upper and lower jaw working model, the dentist attaches the wax denture to the patient's oral cavity, teeth alignment, biting, After the position of the chin is confirmed, the final denture is made by a dental technician.
　特許文献１記載の器具によれば、咬合採得の際、咬合状態の感触を患者が容易に感じとることができ、最適と考えられる下顎位を容易に決定することができるとされている。 According to the instrument described in Patent Document 1, it is said that the patient can easily feel the feeling of occlusion when the occlusion is obtained, and the mandibular position considered to be optimal can be easily determined.
特開２００５－１５２１０６号公報JP 2005-152106 A
　しかしながら、特許文献１記載の器具等を用いても、術者の技術等が不足している場合には、下顎の位置合わせを適切に行うことができず、前記蝋義歯が患者の口腔に装着されたときに患者に適合しないことがある。その場合には、咬合採得をやり直す必要があり、総義歯作製の工程全体に要する時間が長くなるという不都合がある。 However, even if the instrument described in Patent Document 1 is used, if the operator's technique is insufficient, the lower jaw cannot be properly positioned, and the wax denture is attached to the patient's oral cavity. May not fit the patient when done. In that case, it is necessary to redo the occlusal acquisition, which disadvantageously increases the time required for the entire process of preparing the complete denture.
　顆頭安定位の咬合採得に必要なことは、咬合採得の際に上下の歯列が接触してからも水平位は自由に移動できることである。水平的自由移動を与えると下顎頭は下顎窩の中で無理無く安定した一定の位置、顆頭安定位に移動する。下顎頭の移動後に咬合採得を行い、その位置に適切な咬頭嵌合位を人工歯で与えると中心咬合位が定めることができ、中心位と中心咬合位は一致することになる。 What is necessary for obtaining the occlusal position of the condylar stable position is that the horizontal position can move freely even after the upper and lower dentitions come into contact with each other during occlusal acquisition. When the horizontal free movement is given, the mandibular head moves to the stable position of the condyle without any difficulty in the mandibular fossa. If the occlusal is obtained after the mandibular head is moved, and the appropriate intercuspal position is given to the position by the artificial tooth, the central occlusal position can be determined, and the central position and the central occlusal position coincide.
　すなわち、水平的な負荷をゼロにして顎関節が最も噛み易い位置（顆頭安定位＝中心位＝生理的咬合）を咬合採得して、その位置に人工歯を排列や補綴を行い咬頭嵌合位（中心咬合位＝補綴的咬合）を与えれば、中心位と中心咬合位は一致する。しかしながら、このようにして咬合採得を行う方法、器具は今までにはなかった。 In other words, the position where the temporomandibular joint is most chewable with the horizontal load being zero (condylar stable position = center position = physiological occlusion) is obtained by occlusion, and artificial teeth are arranged and prosthetics placed at that position to insert the cusp If an alignment (central occlusion position = prosthetic occlusion) is given, the central position and the central occlusal position coincide. However, there has never been a method or instrument for performing occlusal acquisition in this way.
　本発明は、術者の技術等によらず下顎の位置合わせを精度よく行うことができ、義歯作製の工程全体に要する時間を短縮することができる筋肉位３Ｄ調節器具を提供することを目的とする。さらに、総義歯治療の際に効率よく、理想的な噛み合わせで排列することのできる人工歯を提供することを目的とする。 It is an object of the present invention to provide a muscular position 3D adjusting device that can accurately position the lower jaw regardless of the operator's technique and the like, and can reduce the time required for the entire denture production process. To do. It is another object of the present invention to provide an artificial tooth that can be efficiently arranged during ideal denture treatment with ideal meshing.
　上記目的を達成するために、本発明は、顎位を失った患者の中心位と中心咬合位を一致させる治療で用いられる筋肉位３Ｄ調節器具であって、左右臼歯部に対応する位置に接着される１対の下側部材と、前記下側部材に対向する位置に接着される１対の上側部材とを備え、前記下側部材は、前記上側部材に臨む面に歯列方向に設けられた複数の凹部又は凸部を備え、前記上側部材は、前記下側部材が凹部を備える場合には前記下側部材に臨む面に、先端が各凹部の底面に当接して前記底面上を摺動可能な複数の凸部を備え、前記下側部材が凸部を備える場合には前記下側部材に臨む面に、各凸部の先端が当接して底面上を摺動可能な複数の凹部を備えることを特徴とする（第１発明）。 In order to achieve the above object, the present invention is a 3D muscular position adjustment device used in a treatment for matching the central position and the central occlusal position of a patient who has lost his / her jaw position, and is bonded to a position corresponding to the left and right molar portions. A pair of lower members and a pair of upper members bonded to a position facing the lower member, and the lower member is provided in a dentition direction on a surface facing the upper member. A plurality of recesses or projections, and when the lower member has a recess, the upper member slides on the bottom surface with the tip abutting against the bottom surface of each recess when facing the lower member. A plurality of movable convex portions, and when the lower member has a convex portion, a plurality of concave portions slidable on the bottom surface with the tips of the convex portions coming into contact with the surface facing the lower member (First invention).
　第１発明の筋肉位３Ｄ調節器具は、咬合採得を行うにあたり、下顎側の左右臼歯部に対応する位置に下側部材を接着し、患者の口腔内で咬合動作が行われたときに、上側部材の凸部が下側部材の凹部の底面に当節するように上側部材を接着する。 When the occlusal acquisition is performed, the muscular position 3D adjusting device of the first invention adheres the lower member to a position corresponding to the left and right molar parts on the lower jaw side, and when the occlusal movement is performed in the oral cavity of the patient, The upper member is bonded so that the convex portion of the upper member contacts the bottom surface of the concave portion of the lower member.
　続いて、咬合動作が行われ、咬合動作に伴って、前記凸部の先端が前記凹部の底面に当接して前記凹部の底面上を摺動するように、上側部材の上下位置を調整する。この結果、左右の複数の前記凸部の先端が左右の複数の前記凹部の底面に当接する状態において４つ以上の当接位置によって１つの平面が定まり、この平面を咬合平面とみなして上顎に対する下顎位を決定することができる。そして、決定された上顎に対する下顎位を、前記凸部の先端と前記凹部の底面との当接位置によって記録することができる。 Subsequently, an occlusal operation is performed, and the vertical position of the upper member is adjusted so that the tip of the convex portion comes into contact with the bottom surface of the concave portion and slides on the bottom surface of the concave portion with the occlusal operation. As a result, in the state where the tips of the left and right convex portions are in contact with the bottom surfaces of the left and right concave portions, one plane is determined by four or more abutting positions, and this plane is regarded as an occlusal plane with respect to the upper jaw. The mandibular position can be determined. Then, the determined lower jaw position with respect to the upper jaw can be recorded by the contact position between the tip of the convex portion and the bottom surface of the concave portion.
　第１発明の筋肉位３Ｄ調節器具によれば、前記上側部材の前記凸部の先端が前記下側部材の前記凹部の底面に当接するときの接触面積は、描記ブレードの先端面が記録ブロックに当接する場合と比較して小さいので、術者の技術等によらず下顎の位置合わせを精度よく行うことができる。 According to the muscle position 3D adjusting instrument of the first invention, the contact area when the tip of the convex portion of the upper member abuts against the bottom surface of the concave portion of the lower member is such that the tip surface of the drawing blade is the recording block. Since it is smaller than the case of contact, the lower jaw can be accurately positioned regardless of the operator's technique or the like.
　また、第１発明の筋肉位３Ｄ調節器具によれば、咬合採得で下顎の位置合わせを精度よく行うことが可能であり咬合採得のやり直しが不要となるので、総義歯作製の工程全体に要する時間を短縮することができる。 Further, according to the muscular position 3D adjusting device of the first invention, it is possible to accurately position the lower jaw by obtaining occlusion, and it is not necessary to redo the occlusal acquisition. The time required can be shortened.
　また、第１発明の筋肉位３Ｄ調節器具において、前記下側部材は、下顎咬合堤の左右臼歯部に対応する位置に接着される第１板状部材からなり、前記凹部は、断面視円弧状の凹部であり、前記上側部材は、上顎基礎床の前記下側部材に対向する位置に接着される台座と、前記台座の前記下側部材に臨む側の面の中央部から前記下側部材に向かって突出するネジ部材と、中央部に前記ネジ部材に螺着されるネジ孔部を有する第２板状部材とを備え、前記凸部は、前記第２板状部材の前記下側部材に臨む面の前記ネジ孔部の両側に設けられた球面状体の凸部であることを特徴とする（第２発明）。 In the muscular position 3D adjusting device according to the first aspect of the invention, the lower member is a first plate-like member that is bonded to a position corresponding to the left and right molar portions of the mandibular occlusal levee, and the concave portion is arcuate in cross section. The upper member is a pedestal bonded to a position of the upper base floor facing the lower member, and a central portion of a surface of the pedestal facing the lower member to the lower member. A projecting screw member and a second plate member having a screw hole portion screwed to the screw member at a central portion, and the convex portion is formed on the lower member of the second plate member. It is the convex part of the spherical body provided in the both sides of the said screw hole part of the surface to face (2nd invention).
　第２発明の筋肉位３Ｄ調節器具は、咬合採得を行うにあたり、まず、１対の下側部材が下顎咬合堤の左右臼歯部に対応する位置に接着された下顎基礎床と、上顎咬合堤が付与されていない上顎基礎床とが、患者の口腔内に装着される。 In performing the occlusal acquisition, the muscular position 3D adjusting instrument of the second invention first includes a lower jaw base floor in which a pair of lower members are bonded to positions corresponding to the left and right molar portions of the lower jaw occlusal ridge, and the upper jaw occlusal ridge A maxillary base floor to which is not applied is mounted in the oral cavity of the patient.

While being bonded to a position facing the plate-like member, the distance between the concave portion and the convex portion, that is, the height in the vertical direction of the mandibular occlusion bank with respect to the upper jaw base floor is adjusted.
　前記上下方向の高さ調整は、第２板状部材をネジ部材に対して回動させ、前記ネジ部材の１／２ピッチ単位で第２板状部材を第１板状部材に接近又は後退させることにより行われ、全体の高さが高すぎず低すぎず、左右が均等に接触するように調整される。よって、第２発明の筋肉位３Ｄ調整器具によれば、記録ブロックを削合したりレジンを盛り足したりする場合と比較して、容易且つ迅速に高さ調整を行うことができる。 In the vertical height adjustment, the second plate member is rotated with respect to the screw member, and the second plate member approaches or retracts from the first plate member in units of 1/2 pitch of the screw member. The overall height is not too high and not too low, and is adjusted so that the left and right are evenly contacted. Therefore, according to the muscular position 3D adjusting device of the second invention, the height can be adjusted easily and quickly as compared with the case where the recording block is trimmed or the resin is added.
　続いて、咬合動作が行われ、咬合動作に伴って、球面体状の凸部の先端が断面視円弧形状の凹部の底面に当接して前記凹部の底面上を摺動する。この結果、左右の複数の前記凸部の先端が左右の複数の前記凹部の底面に当接する状態において上顎に対する下顎位を決定することができる。 Subsequently, an occlusal operation is performed, and along with the occlusal operation, the tip of the spherical convex portion comes into contact with the bottom surface of the concave portion having a circular arc shape in section and slides on the bottom surface of the concave portion. As a result, the lower jaw position relative to the upper jaw can be determined in a state where the tips of the left and right convex portions are in contact with the bottom surfaces of the left and right concave portions.
　第２発明の筋肉位３Ｄ調節器具によれば、前記球面体状の凸部の先端が前記断面視円弧形状の凹部の底面上を摺動するときの動きの軌道が、下顎の振り子運動の軌道に略対応しているので、下顎の位置合わせをさらに精度よく行うことができる。 According to the muscular position 3D adjusting instrument of the second invention, the trajectory of the movement when the tip of the convex portion having the spherical body shape slides on the bottom surface of the concave portion having the circular arc shape in cross section is the trajectory of the pendulum motion of the lower jaw. Therefore, the lower jaw can be positioned more accurately.
　また、第２発明の筋肉位３Ｄ調節器具において、前記台座は、側面から外方に向かって突出する係合突起部を備え、前記筋肉位３Ｄ調節器具は、可撓性シートからなる前歯仮排列３Ｄシートを着脱自在に備え、前記前歯仮排列３Ｄシートは、上前歯の排列を表示する上歯排列表示部と、前記上歯排列表示部の両端から延びる延設部の端部に歯列方向に沿って形成され、前記係合突起部に係合可能な係合部とを備えることを特徴とする（第３発明）。 In the muscular position 3D adjusting device according to the second aspect of the invention, the pedestal includes an engaging protrusion that protrudes outward from a side surface, and the muscular position 3D adjusting device is a front tooth temporary arrangement made of a flexible sheet.

　次に、図３～図５を参照して、筋肉位３Ｄ調節器具１の使用方法について説明する。 Next, a method of using the muscle position 3D adjusting device 1 will be described with reference to FIGS.
　咬合採得を行うにあたり、まず、歯科技工士によって、下顎基礎床に下顎咬合堤ＲＬが付与され、下顎咬合堤ＲＬの第１小臼歯から第１大臼歯に相当する部位に１対の第１板状部材１２が第１凹部１４を上に向けて接着される。前記接着には、パラフィンワックス等の蝋材が用いられる。 When performing occlusal acquisition, first, a dental technician applies a lower jaw occlusal ridge RL to the lower mandibular basement floor, and a pair of parts from the first premolar to the first molar of the lower jaw occlusal ridge RL The first plate member 12 is bonded with the first recess 14 facing upward. A wax material such as paraffin wax is used for the bonding.
　次に、歯科医師によって、第１下側部材１１が下顎咬合堤ＲＬに接着された下顎基礎床と、上顎咬合堤ＲＵが付与されていない上顎基礎床ＢＰＵとが、患者の口腔内に装着される。 Then, the dentist, and the mandibular foundation floor first lower member 11 is bonded to the mandibular occlusal ridge R L, and the upper jaw base floor BP U of maxillary occlusal Tsutsumi R U, not granted, the mouth of a patient It is attached to.
　次に、咬合動作が行われたときに第２板状部材２４の凸部２８の先端が凹部１４の底面に当接するように、台座２２が上顎基礎床ＢＰＵの左右の第１板状部材１２に対向する位置（すなわち、第１小臼歯から第１大臼歯に相当する部位）に接着され、凹部１４と凸部２８の間の距離、すなわち、上顎基礎床ＢＰＵに対する下顎咬合堤ＲＬの上下方向の高さが調整される。 Next, the left and right first plate-like members of the upper base floor BP U are arranged so that the tip of the convex portion 28 of the second plate-like member 24 comes into contact with the bottom surface of the concave portion 14 when the occlusion operation is performed. position opposed to the 12 (i.e., from the first bicuspid site corresponding to the first molar) is adhered to, the distance between the recesses 14 and the projections 28, i.e., the lower jaw occlusion ridge for maxillary baseplate BP U R L The vertical height of the is adjusted.
　前記上下方向の高さ調整は、第２板状部材２４をネジ部材２３に対して回動させ、ネジ部材２３の１／２ピッチ単位で第２板状部材２４を第１板状部材１２に接近又は後退させることにより行われ、全体の高さが高すぎず低すぎず、左右が均等に接触するように調整される。よって、記録ブロックを削合したりレジンを盛り足したりする場合と比較して、容易且つ迅速に高さ調整を行うことができる。 The height adjustment in the vertical direction is performed by rotating the second plate-like member 24 with respect to the screw member 23, and changing the second plate-like member 24 to the first plate-like member 12 in units of 1/2 pitch of the screw member 23. It is performed by approaching or retreating, and the overall height is not too high or too low, and is adjusted so that the left and right are in uniform contact. Therefore, the height can be adjusted easily and quickly as compared with the case where the recording blocks are ground or the resin is added.

　続いて、第１下側部材１１が下顎咬合堤ＲＬから取り外され、次に、第１歯冠模型５２の第２凹部５３が第２歯冠模型６２の第２凸部６３に対応する位置となるように、第１歯冠模型５２が下顎咬合堤ＲＬに接着される。この結果、図９に示す状態となる。このような順で第１歯冠模型５２及び第２歯冠模型６２が接着されることにより、前記咬合採得で得られた下顎位を失うことなく、第１歯冠模型５２及び第２歯冠模型６２を上下顎咬合堤ＲＬ，ＲＵに装着することができる。 Subsequently, the first lower member 11 is removed from the lower jaw occlusal ridge RL , and then the second concave portion 53 of the first crown model 52 corresponds to the second convex portion 63 of the second crown model 62. The first crown model 52 is bonded to the lower jaw occlusal ridge RL so that As a result, the state shown in FIG. 9 is obtained. By bonding the first crown model 52 and the second crown model 62 in this order, the first crown model 52 and the second tooth are lost without losing the lower jaw position obtained by the occlusal acquisition. the crown model 62 the upper and lower jaws occlusion ridge R L, may be attached to R U.
　次に、歯科医師によって、第１歯冠模型５２が下顎咬合堤ＲＬに接着された下顎基礎床と、第２歯冠模型６２が上顎咬合堤ＲＵに接着された上顎基礎床ＢＰＵとが患者の口腔内に装着され、患者が最終義歯を装着したときの外観が確認される。 Then, the dentist, and the mandibular foundation floor first crown model 52 is bonded to the mandibular occlusal ridge R L, and maxillary base floor BP U of the second crown model 62 is bonded to the maxillary occlusal Tsutsumi R U Is installed in the patient's mouth, and the appearance when the patient wears the final denture is confirmed.
　続いて、咬合動作が行われ、咬合動作に伴って、第２歯冠模型６２の第２凸部６３の先端が第１歯冠模型５２の盃状の第２凹部５３の底面に当接して底面上を摺動する。これによって、４つの第２凸部６３の先端が４つの第２凹部５３の底面に当接する状態において、患者が最終義歯を装着したときの上顎に対する下顎位を確認することができる。 Subsequently, the occlusal operation is performed, and the tip of the second convex portion 63 of the second crown model 62 comes into contact with the bottom surface of the bowl-shaped second concave portion 53 of the first crown model 52 along with the occlusal operation. Slide on the bottom. Thereby, in a state where the tips of the four second convex portions 63 are in contact with the bottom surfaces of the four second concave portions 53, it is possible to confirm the lower jaw position relative to the upper jaw when the patient wears the final denture.
　このとき、第１歯冠模型５２の盃状の第２凹部５３の開口部は、第１板状部材１２の断面視円弧形状の第１凹部１４の開口部よりも最終歯冠形態に近く、また、第２歯冠模型６２の第２凸部６３の錘状の先端は、第２板状部材２４の球面状体の第１凸部２８の先端よりも最終歯冠形態に近いので、筋肉位試適用人工歯４１によれば、筋肉位３Ｄ調節器具１と比較して、上顎に対する下顎位をさらに精度よく確認することができる。 At this time, the opening portion of the second concave portion 53 of the bowl shape of the first crown model 52 is closer to the final crown shape than the opening portion of the first concave portion 14 in the arc shape of the first plate-like member 12, Further, the weight-shaped tip of the second convex portion 63 of the second crown model 62 is closer to the final crown shape than the tip of the first convex portion 28 of the spherical body of the second plate-like member 24, so that muscles According to the position trial application artificial tooth 41, the lower jaw position with respect to the upper jaw can be confirmed with higher accuracy than the muscle position 3D adjusting device 1.
　次に、筋肉位試適用人工歯のバリエーションである第２の態様について説明する（図８Ａ）。筋肉位試適用人工歯は、以下のように薄い凸状の部材を患者口腔内で接着して調整してもよい。筋肉位試適用人工歯７１は、下顎咬合堤ＲＬの左右の臼歯部に接着される１対の第２下側部材７２と、上顎基礎床ＢＰＵに付与された上顎咬合堤ＲＵの第２下側部材７２に対向する部位に接着される１対の第２上側部材７３とを備える。 Next, the 2nd aspect which is a variation of the muscular position trial application artificial tooth is demonstrated (FIG. 8A). The muscular position trial application artificial tooth may be adjusted by bonding a thin convex member in the patient's oral cavity as follows. Muscle position try-for artificial teeth 71, a second lower member 72 of the pair is bonded to the posterior part of the left and right mandibular occlusal ridge R L, the maxillary occlusal Tsutsumi R U granted maxillary baseplate BP U 2 A pair of second upper members 73 that are bonded to a portion facing the lower member 72.
　第２下側部材７２は、下顎の第１小臼歯、第２小臼歯、第１大臼歯及び第２大臼歯を模した４本の歯冠模型ＣＭＡＬ，ＣＭＢＬ，ＣＭＣＬ，ＣＭＤＬを連結した第１歯冠模型７４からなる。第１歯冠模型７４は、咬合面７５が、深さ０．０～１．５ｍｍの浅いくぼみ７６が形成されている以外は、第１の態様の筋肉位試適用人工歯４１と同じに構成されている。咬合面７５をほぼ平坦、又は浅い窪みに形成することによって、下顎位の微妙な調整を行なうことが可能となる。 The second lower member 72 includes four crown models CM AL , CM BL , CM CL , CM DL imitating the first premolar, the second premolar, the first premolar and the second premolar of the lower jaw. It consists of a connected first crown model 74. The first crown model 74 is configured in the same manner as the artificial tooth 41 applied with the muscle position trial of the first aspect, except that the occlusal surface 75 is formed with a shallow recess 76 having a depth of 0.0 to 1.5 mm. Has been. By forming the occlusal surface 75 in a substantially flat or shallow depression, it is possible to finely adjust the lower jaw position.
　第２上側部材７３は、上顎の第１小臼歯、第２小臼歯、第１大臼歯及び第２大臼歯を模した４本の歯冠模型ＣＭＡＵ，ＣＭＢＵ，ＣＭＣＵ，ＣＭＤＵを連結した第２歯冠模型７７からなる。第２歯冠模型７７は、咬合面７８から突出する第２凸部７９が、ドーム状である以外は第１の態様の筋肉位試適用人工歯と同じに構成されている。第２凸部７９は、直径１．０～６．０ｍｍ、厚さ０．３～６．０ｍｍのドーム形状の凸状部材を必要な枚数だけ作製した歯冠模型に重ね合わせて接着して作製する。例えば厚さ０．３ｍｍの部材を用いる場合には、０．３ｍｍずつ高さを増して作製することができる。厚さを増して高さを調整することにより、微細な高さ調整が可能となり、より精度良く顎位の調整を行うことができる。 The second upper member 73 connects four crown models CM AU , CM BU , CM CU , CM DU imitating the first premolar, the second premolar, the first premolar and the second premolar of the upper jaw. The second crown model 77. The second crown model 77 is configured in the same manner as the artificial tooth for applying a muscle position test of the first aspect, except that the second convex portion 79 protruding from the occlusal surface 78 has a dome shape. The second convex portion 79 is produced by overlaying and bonding a necessary number of dome-shaped convex members having a diameter of 1.0 to 6.0 mm and a thickness of 0.3 to 6.0 mm on a crown model. To do. For example, when a member having a thickness of 0.3 mm is used, the height can be increased by 0.3 mm. By adjusting the height by increasing the thickness, fine height adjustment is possible, and the jaw position can be adjusted more accurately.
　図８Ａに示す第１歯冠模型７４及び第２歯冠模型７７は左用であるが、右用は、図８に示すものとは左右対称に形成されている。第１歯冠模型７４及び第２歯冠模型７７は、臼歯の排列が患者に適合するように、歯の大きさを変えて複数用意されている。第２凸部は第１の態様の筋肉位試適用人工歯と同様に３つでもよく４つでもよい。 The first crown model 74 and the second crown model 77 shown in FIG. 8A are for the left side, but the right side is formed symmetrically with the one shown in FIG. A plurality of first crown models 74 and second crown models 77 are prepared by changing the size of the teeth so that the arrangement of the molars fits the patient. The number of the second convex portions may be three or four, similar to the muscle position trial application artificial tooth of the first aspect.
　さらに、図８Ｂに示すように、凹部を平面状の咬合部に形成するのではなく、複数の凸状部材８１に囲まれた凹状部８２として構成してもよい。第２下側部材７２ａの咬合面に凸状部材８１を複数接着することにより、凸状部材８１に囲まれた相対的な窪みが形成される。凹状部８２は、上記第２凹部７６と同様、第２歯冠模型７７の第２凸部と摺動させて位置を調整する。凸状部材８１は、直径０．２～６．０ｍｍ、厚さ０．２～６．０ｍｍとし、２～８個程度接着することによって窪みを形成すればよい。図８Ｂでは、３つの凸状部材８１を接着することにより凹状部８２を形成する態様を示しているが、凸状部材８１は、歯の位置に合せてどのように接着してもよい。例えば、小さい凸状部材を同心円上に二重、三重に貼ることによって、同心円上に接着された凸状部材の中央に凹状部が形成されるような態様としてもよい。また、ハニカム形状を想定し、その中心部分に凸状部材を接着すれば、隣接する凸状部材間に複数の凹上部を形成することができる。また、凸状部材を不規則な配置で接着することにより、凸状部材間に複数の凹状部を形成する態様としてもよい。 Further, as shown in FIG. 8B, the concave portion may be formed as a concave portion 82 surrounded by a plurality of convex members 81 instead of forming the concave portion in a planar occlusal portion. By bonding a plurality of convex members 81 to the occlusal surface of the second lower member 72a, a relative recess surrounded by the convex members 81 is formed. The concave portion 82 adjusts the position by sliding with the second convex portion of the second crown model 77, similarly to the second concave portion 76. The convex member 81 has a diameter of 0.2 to 6.0 mm and a thickness of 0.2 to 6.0 mm, and a depression may be formed by bonding about 2 to 8 pieces. Although FIG. 8B shows a mode in which the concave portion 82 is formed by bonding three convex members 81, the convex member 81 may be bonded in any manner according to the position of the teeth. For example, it is good also as an aspect in which a concave part is formed in the center of the convex member adhere | attached on the concentric circle by sticking a small convex member on a concentric circle double and triple. Further, assuming a honeycomb shape and bonding a convex member to the central portion thereof, a plurality of concave upper portions can be formed between adjacent convex members. Moreover, it is good also as an aspect which forms a some recessed part between convex members by adhere | attaching a convex member by irregular arrangement | positioning.
　ここでは、凹部を備える第１歯冠模型、凸部を備える第２歯冠模型を例に説明したが、凸部を第１歯冠模型に設け、凹部を第２歯冠模型に設ける構成としてもよい。さらに、咬頭位置についても、図７Ａ及びＢに示すように舌側に設けてもよいし、頬側に設ける構成にしてもよい。 Here, the first crown model having the concave portion and the second crown model having the convex portion have been described as examples. However, the convex portion is provided in the first crown model and the concave portion is provided in the second crown model. Also good. Further, the cusp position may be provided on the lingual side as shown in FIGS. 7A and 7B or may be provided on the cheek side.
　筋肉位試適用人工歯による顎位を精度良く調整した後、第１歯冠模型５２又は７４及び第２歯冠模型６２又は７７が下顎基礎床及び上顎基礎床ＢＰＵごと患者の口腔から取り出され、歯科技工士によって最終義歯が形成される。一般に最終義歯に用いられる人工歯は、臼歯、前歯など、いくつかの部分に分けて販売されている。しかし、噛み合わせ良く人工歯を排列するためには、熟練を要し、また、時間をかける必要がある。そこで、必要な人工歯のみを切り離して簡単に使用することができる人工歯９１、９２（マジックカットシステム）を用いればよい。図１０Ａ及び１０Ｂに示すように、隣接する歯との間に図中矢印で示すような深い切れ目をいれておくことにより、簡単に切断可能な人工歯９１、９２を提供することができる。図示しているのは、４歯用のものであるが、１６歯までの連結歯を適宜作成することができる。特に、第一小臼歯から第２大臼歯までの４歯用、犬歯から第２大臼歯までの５歯用は治療のうえでも汎用性が高い。 After accurately adjusting the chin position by the artificial position trial artificial tooth, the first crown model 52 or 74 and the second crown model 62 or 77 are taken out from the patient's oral cavity together with the mandibular base floor and the maxillary base floor BP U. The final denture is formed by the dental technician. In general, artificial teeth used for final dentures are sold in several parts such as molars and anterior teeth. However, in order to arrange artificial teeth with good meshing, skill is required and time is required. Therefore, artificial teeth 91 and 92 (magic cut system) that can be easily used by separating only necessary artificial teeth may be used. As shown in FIGS. 10A and 10B, artificial teeth 91 and 92 that can be easily cut can be provided by making deep cuts as shown by arrows in the figure between adjacent teeth. Although illustrated is for four teeth, connecting teeth up to 16 teeth can be appropriately created. In particular, the use for 4 teeth from the first premolar to the second molar and the use for 5 teeth from the canine to the second premolar are highly versatile in terms of treatment.
　理想的な噛み合わせを予め排列した状態で供給することにより、作業時間を大幅に削減することができる。さらに、必要な人工歯のみ切断して使用することにより、無駄を省くことができる。さらに、図１０Ｂに示すように、頬舌的な幅径を天然歯の平均値を参考とし、近遠心的な奥行きは第一小臼歯・第二小臼歯・第一大臼歯までを天然歯の平均値を参考にし、第二大臼歯９３は近遠心的に約半分の幅にすることで、モンゴロイドに多い顎堤に奥行きが無い患者でも配置が容易になる。 供給 す る By supplying ideal meshing in a pre-arranged state, working time can be greatly reduced. Furthermore, waste can be eliminated by cutting and using only the necessary artificial teeth. Furthermore, as shown in FIG. 10B, the buccal tongue width diameter is referred to the average value of the natural teeth, and the near-distant depth is from the first premolar, the second premolar, and the first premolar to the natural tooth. With reference to the average value, the second molar 93 is approximately half the width in a near-centrifugal manner, so that even a patient who does not have a depth in the ridge of the mongoloid is easy to place.
