Description

【０００１】
【発明の属する技術分野】
本発明は、入れ歯製造方法、歯科用歯型トレイおよび歯科用歯型トレイと咬合器のセットに関する。
【０００２】
【従来の技術】
入れ歯を製作するには、入れ歯を取付ける患者の歯肉部の形状を転写した顎印象の採取と、上顎の人工歯と下顎の人工歯との間の咬合の調整が必要である。従来技術は、かかる入れ歯の製造方法において、石膏技術を多用していた。従来技術による入れ歯の製造方法を、図１２のフローチャートに従い、図１３から図２０を用いつつ説明する。
【０００３】
Ｓ１は、顎印象採取工程で、入れ歯を取付ける患者の歯肉部の形状を、印象材に転写する工程である。図１３において、歯科用歯型トレイ１Ａに、印象材３Ａとして軟らかい状態のアルジネート（材料名）を適当な厚さに盛る。そのアルジネートを患者の口腔内の歯肉部に押し当てて、歯肉部の形状５Ａを転写する。アルジネートは、歯科用に一般に用いられる材料で、水に溶かして、軟らかいゲル状態にできる。印象材として、アルジネートが主に用いられるが、シリコン、石膏、コンパウンド等が用いられることもある。歯科用歯型トレイは、ほぼ口腔内の顎形状に近い形状に湾曲加工された、薄いアルミ等の金属板または金網状のものに取っ手がついた外形を有している。
【０００４】
Ｓ３は、石膏盛り工程で、印象材の、歯肉部の形状が転写されている部分の上に石膏を盛り、固まらせる工程である。図１４において、歯肉部の形状５Ａが転写されている印象材３Ａの上に、石膏７Ａを盛る。石膏が固まるには、約三十分を要する。
【０００５】
Ｓ５は、顎模型形成工程で、Ｓ３において石膏が十分固まったのちに、印象材より石膏部分を外し、石膏部分に再転写された歯肉部の形状を顎模型とする工程である。この段階で、歯科用歯型トレイ１Ａおよび印象材３Ａ部分は役目を果たし、歯科用歯型トレイ１Ａは、印象材３Ａ部分が除去され再利用される。
【０００６】
Ｓ７は、ロウ堤形成工程で、石膏の顎模型の上に歯肉部の部分に沿い、ロウを堤のように盛る工程である。図１５において、すでに歯科用歯型トレイから分離された石膏７Ａの、顎模型の歯肉部の形状５Ａ上に、ロウ堤９Ａが盛られる。ロウは、歯科用パラフィンワックスを用いることができる。また、歯肉部の形状５Ａとロウ堤９Ａとの間に、薄く歯科用レジンを塗り、これをレジン床として用いることもできる。
【０００７】
Ｓ９は、石膏土台整形工程で、次工程の準備工程である。すなわち次工程において、ロウ堤付き石膏の顎模型が咬合器に取付けやすいよう、そのロウ堤と反対側の外形を、咬合器の取付部分よりやや小さめの外形に削り整形する工程である。
【０００８】
Ｓ１１は、咬合器取付工程で、前工程において整形された、ロウ堤付き石膏の顎模型を、咬合器に固定し取付ける工程である。固定には石膏を用い、咬合器の取付部分にロウ堤付き石膏の顎模型を置き、隙間を石膏で埋めて固定する。固定には約３０分を要する。図１６において、前工程において整形された、ロウ堤付き石膏７Ａの顎模型は、ロウ堤９Ａと反対側で咬合器の取付部分１１Ａに配置し、隙間１３Ａを石膏で埋めて固定する。
【０００９】
Ｓ１からＳ１１までの工程の説明は、上顎部分について行ったが、同様の工程が下顎部分についても行われる。石膏を用いる工程も、Ｓ３の石膏盛り工程、Ｓ９の石膏土台整形工程、Ｓ１１の咬合器取付工程について行われる。
【００１０】
Ｓ１３は、人工歯植設工程で、上顎用のロウ堤付き石膏の顎模型と、下顎用のロウ堤付き石膏の顎模型とを咬合器に取付け、患者の咬み合わせ位置を別途測定して、その咬み合わせ位置にあわせ、上顎用のロウ堤と下顎用のロウ堤の高さを削って調整し、そのロウ堤に人工歯を順次植設する。人工歯の植設は、咬合器を用い、上顎用人工歯と下顎用人工歯とが、適切な咬み合わせとなるよう、順次調整を行う。
【００１１】
図１７において、咬合器の上顎用取付部分１１Ａにロウ堤９Ａ付き上顎用石膏７Ａの顎模型が取付けられ、上顎用の人工歯１５Ａが植設される。同様に、咬合器の下顎用取付部分１１Ｂにロウ堤９Ｂ付き下顎用石膏７Ｂの顎模型が取付けられ、下顎用の人工歯１５Ｂが植設される。咬合器の構造は、このような咬合状態を観察する位置関係の他に、下顎用取付部分１１Ｂに対し、上顎用取付部分１１Ａをほぼ百八十度回転した位置関係の状態にできる。そこで、上顎用の人工歯１５Ａと下顎用の人工歯１５Ｂとの咬み合わせが適切でないときは、この百八十度回転した位置関係の状態で、人工歯に対し作業しやすい状態にし、その人工歯の部分のロウ堤を熱により軟化させ、再び咬合状態を観察する位置関係に戻し、咬み合わせを確認する。この作業を順次行うことで、適切な咬み合わせに調整できる。なお、図１７以下の図面では、説明の便宜上、人工歯が４本の場合を示すが、これ以外の人工歯の植設の場合も同様にして、以下の工程が行われる。
【００１２】
Ｓ１５は、石膏内埋込工程で、適切な咬み合わせに調整された人工歯付きロウ堤を含む石膏の顎模型が、咬合器から外され、容器内に配置され、周囲を石膏で埋め込まれる工程である。この工程は、上顎用顎模型と下顎用顎模型と、別々に行われる。図１８において、上顎用の人工歯１５Ａ付きロウ堤９Ａを含む石膏７Ａの顎模型が、容器１７Ａ内に配置され、まず下半分の周囲が石膏１９Ａで埋められる。次に上半分も石膏２１Ａで埋められる。石膏１９Ａと石膏２１Ａとの境界面２３Ａおよび、上顎用の人工歯１５Ａ付きロウ堤９Ａを含む石膏７Ａの顎模型の周囲に離型材が予め塗られる。
【００１３】
Ｓ１７は、ロウ除去工程で、容器ごと適切な温度に加熱し、ロウを溶かし、容器の外に流出させて除去する工程である。図１９は、ロウ堤が流出した後を示した図で、流出したロウ堤部分に対応し、歯肉部の形状５Ａで縁取られた空洞部分２５Ａが形成される。人工歯１５Ａは、石膏２１Ａに埋め込まれた状態で保持される。
【００１４】
Ｓ１９は、レジン歯肉部形成工程で、空洞部分２５Ａに、歯科用レジンを充填し、硬化した後に、石膏１９Ａ、石膏２１Ａを容器１７Ａから外し、境界面２３Ａで割って、空洞部に充填された歯科用レジンを取り出す。このとき、人工歯は、歯科用レジンにより固定され、歯科用レジンの人工歯と反対側は歯肉部の形状を備え、全体として入れ歯が形成される。その後必要な整形を施し入れ歯が完成する。図２０は、このようにして得られた、人工歯１５Ａと歯肉部の形状５Ａとを備えた歯科用レジン床２７Ａの、完成した上顎用入れ歯２９Ａを示す。
【００１５】
下顎用入れ歯も、同様にして、Ｓ１５からＳ２０の工程を行うことで得ることができる。
【００１６】
【発明が解決しようとする課題】
従来技術により、入れ歯を製造することができる。しかし、従来技術は石膏技術を多用し、石膏の硬化時間のために入れ歯の製造に長期間を要する。入れ歯を製造するのに要する時間を分析すると、人工歯の咬合調整についで石膏の硬化時間が長い時間を要する。とくに、患者にとり、咬合器にロウ堤付き石膏の顎模型が取付けられる迄は、通院を要するが、この間に石膏の硬化時間のための待ち時間が生ずる。
【００１７】
本発明の目的は、かかる従来技術の課題を解決し、入れ歯の製造において、石膏の硬化時間を少なくし、とくに、患者の通院期間における石膏の硬化時間をなくし、入れ歯の製造が短期間で行える入れ歯製造方法、歯科用歯型トレイおよび歯科用歯型トレイと咬合器のセットを提供することである。
【００１８】
【課題を解決するための手段】
上記目的を達成するため、本発明に係る入れ歯製造方法は、人工歯を植設する歯科用歯型トレイと、植設された前記人工歯の咬合を調整する咬合器とのセットを用いて、入れ歯を製造する入れ歯製造方法であって、前記入れ歯を取付ける患者の歯肉部の形状を転写した顎印象部材を一方側の面に有する前記歯科用歯型トレイの他方側の面にロウ堤を設けるロウ堤形成工程と、前記咬合器に設けられるトレイ装着部と、前記歯科用歯型トレイの側面に設けられる装着対応部材と、を用いて前記歯科用歯型トレイを前記咬合器に装着する歯科用歯型トレイ装着工程と、前記ロウ堤に前記人工歯を植設し、前記咬合を調整する人工歯植設工程と、を備え、前記顎印象部材と咬合調整された前記人工歯とを保持する前記歯科用歯型トレイに基き、前記入れ歯を製造することを特徴とする。
【００１９】
また、本発明に係る歯科用歯型トレイは、人工歯の咬合を調整する咬合器に装着し、入れ歯を製造するのに用いる歯科用歯型トレイであって、前記入れ歯を取付ける患者の歯肉部の形状を転写した顎印象部材を保持する一方側の面と、少なくとも一つのロウ堤固定くさびが設けられ、前記人工歯を植設するロウ堤を保持する他方側の面と、側面に設けられる装着対応部材であって、前記咬合器に設けられるトレイ装着部に装着される装着対応部材と、を備え、前記顎印象部材と咬合調整された前記人工歯とともに前記入れ歯を製造するために用いられることを特徴とする。
【００２０】
また、本発明に係る歯科用歯型トレイと咬合器のセットは、人工歯を植設する歯科用歯型トレイと、歯科用歯型トレイを装着し、植設された前記人工歯の咬合を調整する咬合器とのセットであって、前記咬合器は、前記歯科用歯型トレイを装着するトレイ装着部を備え、前記歯科用歯型トレイは、前記入れ歯を取付ける患者の歯肉部の形状を転写した顎印象部材を保持する一方側の面と、少なくとも一つのロウ堤固定くさびが設けられ、前記人工歯を植設するロウ堤を保持する他方側の面と、側面に設けられ、前記咬合器の前記トレイ装着部に装着される装着対応部材と、を備え、前記トレイ装着部と前記装着対応部材とを用いて前記歯科用歯型トレイを前記咬合器に装着し、前記顎印象部材と前記人工歯とを保持する前記歯科用歯型トレイに基き、前記咬合を調整し、前記入れ歯を製造するために用いられることを特徴とする。
【００２１】
本発明に係る入れ歯製造方法は、歯科用歯型トレイの一方側の面に入れ歯を取付ける患者の歯肉部の形状を転写した顎印象部材を有し、他方側の面に人工歯を植設するロウ堤を設け、その顎印象とロウ堤とを保持する歯科用歯型トレイをそのまま咬合器に装着する。したがって、咬合器に装着する以前の工程に石膏工程が全くなく、石膏の硬化時間を少なくし、とくに、患者の通院期間における石膏の硬化時間をなくし、入れ歯の製造が短期間で行える。
【００２２】
また、本発明に係る歯科用歯型トレイは、顎印象部材を保持する一方側の面と、少なくとも一つのロウ堤固定用突起を設け人工歯を植設するロウ堤を保持する他方側の面と、側面に設けられる装着対応部材であって、咬合器に設けられるトレイ装着部に装着される装着対応部材を備える。したがって、トレイ装着部と装着対応部材とを用いて、顎印象部材とロウ堤とを保持したまま咬合器に装着することができ、かかる歯科用歯型トレイを用いて入れ歯を製造するとき、咬合器に装着する以前の工程に石膏工程が全くなく、石膏の硬化時間を少なくし、とくに、患者の通院期間における石膏の硬化時間をなくし、入れ歯の製造が短期間で行える。
【００２３】
【発明の実施の形態】
以下、図１のフローチャートに従い、図２から図１１を用いつつ、本発明の実施の形態の関連について詳細に説明する。従来技術と共通の要素については、同一の符号を付し、説明を省略する。
【００２４】
図１のＳ５１は、顎印象採取工程で、従来技術と同様に、入れ歯を取付ける患者の歯肉部の形状を印象材に転写し、顎印象部材を得る工程であるが、歯科用歯型トレイと、印象材の材料が異なる。
【００２５】
図２に、上顎用の歯科用歯型トレイ５１Ａ、下顎用の歯科用歯型トレイ５１Ｂを示す。これらの歯科用歯型トレイ５１Ａ，５１Ｂは、ほぼ口腔内の顎形状に近い形状に湾曲加工した薄いアルミ等の金属板、金網状のものまたはレジン等を用いることができる。例えば、上下の顎のスキマが少ない患者に対して、レジン材質の歯科用歯型トレイを用い、これを切削加工等で患者の顎形状に合わせて調整することもできる。また、取っ手がついた外形にすることもできる。
【００２６】
さらに、これらの歯科用歯型トレイ５１Ａ，５１Ｂは、顎印象部材を保持する一方側の面５３Ａ，５３Ｂと、ロウ堤を保持する他方側の面５５Ａ，５５Ｂを有し、他方側の面５５Ａ，５５Ｂには、ロウ堤を固定するためのくさび５７Ａ，５７Ｂが少なくとも一つ設けられ、また側面に、咬合器の歯科用歯型トレイを装着するトレイ装着部部分に対応し、このトレイ装着部に装着される装着対応部材５９Ａ，５９Ｂが複数設けられる。装着対応部材５９Ａ，５９Ｂは、鋼製の矩形板を歯科用歯型トレイ５１Ａ，５１Ｂに半分埋め込んで用いる。咬合器の歯科用歯型トレイを装着するトレイ装着部に止めネジを用いるときは、止めネジの位置が定まるくぼみを設ける。
【００２７】
歯科用歯型トレイの一方側の面が顎印象部材を有するものとするには、図３において、上顎用の歯科用歯型トレイ５１Ａに、軟らかい状態の印象材を適当な厚さに盛り、患者の口腔内の歯肉部に押し当てて、歯肉部の形状５Ａを転写し、顎印象部材６３Ａを得る。印象材として、温度等に対し変形能の少ない材料、好ましくは、シリコン樹脂を用いる。このことで、転写された歯肉部の形状５Ａを、変形を起こすことなく必要な期間、保持することができる。
【００２８】
Ｓ５３は、ロウ堤形成工程で、歯科用歯型トレイの、顎印象部材を保持する一方側の面に対し他方側の面の歯肉部の部分に沿い、ロウを堤のように盛る工程である。図４において、歯科用歯型トレイ５１Ａの、顎印象部材６３Ａを保持する一方側の面に対し他方側の面にロウ堤６５Ａが盛られる。ロウは、歯科用パラフィンワックスを用いることができる。また、歯科用歯型トレイ５１Ａとロウ堤６５Ａとの間に、薄く歯科用レジンを塗り、これをレジン床として用いることもできる。
【００２９】
Ｓ５５は、咬合器装着工程で、顎印象部材とロウ堤とを保持した歯科用歯型トレイを、咬合器に装着する工程である。
【００３０】
図５は、咬合器７１で、ベース７３と回転アーム７５を有し、回転アームは、ベースの回転支持部７７を中心に、図示した矢印のように、ほぼ百八十度回転することができる。ベース７３は、支持部７９により、下顎取付部８１Ｂを支持し、下顎取付部８１Ｂは、下顎用の歯科用歯型トレイを装着するトレイ装着部としての装着ネジ８３Ｂを備える。また、回転アーム７５は、上顎取付部８１Ａを有し、上顎用の歯科用歯型トレイを装着するトレイ装着部としての装着ネジ８３Ａを備える。
【００３１】
装着ネジ８３Ａ，８３Ｂは、歯科用歯型トレイを安定して保持し固定するのに適した位置に、上顎用、下顎用にそれぞれ複数個、好ましくはそれぞれ三個以上設けられる。トレイ装着部は、装着ネジの他、例えばバネ付きピン等を用いることもできる。さらに、咬合器７１のトレイ装着部と、歯科用歯型トレイの装着対応部材との対応する部分の形状をはめ合わせにして、位置決めをより確実にすることもできる。
【００３２】
図６は、歯科用歯型トレイ５１Ａ，５１Ｂを、咬合器７１に装着し、ロウ堤６５Ａ，６５Ｂの高さを、別途計測した患者の咬み合わせ位置の高さに調整した状態を示す。このように、歯科用歯型トレイ５１Ａ，５１Ｂの装着対応部材５９Ａ，５９Ｂと、咬合器７１の装着ネジ８３Ａ，８３Ｂとを用いることで、顎印象部材６３Ａ，６３Ｂとロウ堤６５Ａ，６５Ｂとを保持したままの状態で、歯科用歯型トレイ５１Ａ，５１Ｂを咬合器７１に装着することができる。
【００３３】
Ｓ５５の咬合器装着工程までは、患者の顎印象の採取、咬み合わせ位置の計測等があり、患者の通院を要する。ここで本発明の特徴は、これまでの工程に一切石膏技術を用いることがないことにあり、このため石膏の硬化のための待ち時間がなく、工程に要する時間が大幅に短縮される。
【００３４】
これ以後の工程は、顎印象部材と人工歯付きロウ堤とを保持する歯科用歯型トレイを一体として入れ歯の製造を行う点に特徴があるが、製造技術は従来技術と共通の部分が多いので、図面を参照しつつ特徴点を中心に述べる。
【００３５】
Ｓ５７は、人工歯植設工程で、ロウ堤に人工歯を順次植設し、咬合器を用い、上顎用人工歯と下顎用人工歯とが、適切な咬み合わせとなるよう、順次調整を行う。図７に、歯科用歯型トレイ５１Ａ，５１Ｂに保持されたロウ堤６５Ａ，６５Ｂに人工歯１５Ａ，１５Ｂが植設される様子を示す。
【００３６】
Ｓ５９は、石膏内埋込工程で、適切な咬み合わせに調整された人工歯付きロウ堤と、顎印象部材を保持した歯科用歯型トレイが、咬合器から外され、容器内に配置され、下半分、上半分の二回に分けて、周囲を石膏で埋め込まれる工程である。この工程は、上顎用の歯科用歯型トレイと下顎用の歯科用歯型トレイと、別々に行われる。図８にその様子を示す。容器１７Ａに配置される対象が、人工歯付きロウ堤と、顎印象部材を保持した歯科用歯型トレイである点を除けば、製造技術は、従来技術で述べた内容と共通であり、説明を省略する。
【００３７】
Ｓ６１は、ロウ除去工程で、容器ごと適切な温度に加熱し、ロウを溶かし、容器の外に流出させて除去する工程である。図９は、ロウ堤が流出した後を示した図で、流出したロウ堤部分に対応し、空洞部分８７Ａが形成される。人工歯１５Ａは、石膏に埋め込まれた状態で保持される。
【００３８】
Ｓ６３は、トレイ除去工程で、容器内の石膏から、歯科用歯型トレイと、顎印象部材を除去する工程である。図９の状態から、容器１７Ａ内の上半分の石膏、下半分の石膏を一旦分離し、下半分の石膏から、空洞部分８７Ａにより露出した歯科用歯型トレイ５１Ａと、顎印象部材６３Ａとを除去する。除去後、再び上半分の石膏と下半分の石膏を合わせて容器１７Ａに収納する。図１０は、除去後の容器内の状態を示してある。このときの空洞部分８９Ａは、先ほどの空洞部分８７Ａより広がり、歯肉部の形状５Ａで縁取られた空洞部分となる。取り除かれた歯科用歯型トレイ５１Ａは、再利用される。
【００３９】
Ｓ６５は、レジン歯肉部形成工程で、空洞部分に、歯科用レジンを充填し、硬化した後に、上半分の石膏、下半分の石膏を容器から外し、境界面で割って、空洞部分に充填された歯科用レジンを取り出す。このとき、人工歯は、歯科用レジンにより固定され、歯科用レジンの人工歯と反対側は歯肉部の形状を備え、全体として入れ歯が形成される。その後必要な整形が施され、入れ歯が完成する。図１１は、このようにして得られた、人工歯１５Ａと歯肉部の形状５Ａとを備えた歯科用レジン床９１Ａの、完成した上顎用入れ歯９３Ａを示す。
【００４０】
下顎用入れ歯も、同様にして、Ｓ５９からＳ６５の工程を行うことで得ることができる。
【００４１】
なお、図７から図１１の表示は便宜上臼歯が４本の入れ歯について行ったが、これ以外の本数についても本発明が実施でき、また臼歯の入れ歯のほか、前歯の入れ歯、あるいは前歯と臼歯の組合せ、全部の歯についての総入れ歯についても、本発明が実施できる。
【００４２】
Ｓ５５までの工程と異なり、Ｓ５９以降の工程では、本発明においても従来技術と同様に、石膏技術が用いられる。しかし、Ｓ５７の人工歯植設工程以後は、患者の通院を必要としない工程であるので、患者にとり、待ち時間の負担が生じない。
【００４３】
【発明の効果】
本発明に係る入れ歯製造方法、歯科用歯型トレイおよび歯科用歯型トレイと咬合器のセットは、入れ歯の製造において、石膏の硬化時間を少なくし、とくに、患者の通院期間における石膏の硬化時間をなくし、入れ歯の製造が短期間で行える。

BACKGROUND OF THE INVENTION
The present invention relates to a method dentures manufactured, a dental dental cast tray and a set of dental tooth mold tray and the articulator.
[0002]
[Prior art]
In order to manufacture dentures, it is necessary to collect jaw impressions that transfer the shape of the gingiva of the patient to whom the dentures are to be attached, and to adjust the occlusion between the upper and lower artificial teeth. In the prior art, gypsum technology has been frequently used in the manufacturing method of such dentures. A method for manufacturing dentures according to the prior art will be described with reference to FIGS. 13 to 20 according to the flowchart of FIG.
[0003]
S1 is a process of transferring the shape of the patient's gingival part to which the denture is attached to the impression material in the jaw impression collecting process. In FIG. 13, a soft alginate (material name) as an impression material 3A is put on the dental tooth tray 1A to an appropriate thickness. The alginate is pressed against the gingival part in the oral cavity of the patient to transfer the shape 5A of the gingival part. Alginate is a material commonly used for dentistry, and can be dissolved in water to form a soft gel. Alginate is mainly used as the impression material, but silicon, gypsum, compound and the like may be used. The dental tooth tray has an outer shape with a handle attached to a metal plate such as a thin aluminum plate or a wire net, which is curved into a shape almost similar to a jaw shape in the oral cavity.
[0004]
S3 is a step of depositing and solidifying gypsum on the portion of the impression material where the shape of the gingival portion is transferred in the gypsum depositing step. In FIG. 14, plaster 7 A is placed on the impression material 3 A onto which the gingival shape 5 A has been transferred. It takes about 30 minutes for the plaster to harden.
[0005]
S5 is a jaw model forming step in which the gypsum portion is removed from the impression material after the gypsum is sufficiently hardened in S3, and the shape of the gingiva portion re-transferred to the gypsum portion is used as the jaw model. At this stage, the dental tooth tray 1A and the impression material 3A portion play a role, and the dental tooth tray 1A is removed and reused.
[0006]
S7 is a process of forming a wax like a bank along a gingival part on a plaster jaw model in a wax bank formation process. In FIG. 15, a wax dyke 9A is placed on the gingival shape 5A of the jaw model of gypsum 7A that has already been separated from the dental tooth tray. As the wax, dental paraffin wax can be used. Also, a dental resin can be applied thinly between the gingival shape 5A and the brace 9A, and this can be used as a resin floor.
[0007]
S9 is a gypsum foundation shaping process, which is a preparation process for the next process. That is, in the next process, the outer shape on the opposite side of the wax levee is shaved and shaped to be slightly smaller than the attachment portion of the articulator so that the jaw model of the gypsum with the wax levee can be easily attached to the articulator.
[0008]
S11 is a step of fixing and attaching the gypsum jaw model with a wax embankment shaped in the previous step to the articulator in the articulator attachment step. Gypsum is used for fixing, and a plaster jaw model with a wax dyke is placed on the attachment part of the articulator, and the gap is filled with gypsum and fixed. Fixing takes about 30 minutes. In FIG. 16, the jaw model of the plaster 7A with the wax levee shaped in the previous step is placed on the attachment portion 11A of the articulator on the side opposite to the wax ridge 9A, and the gap 13A is filled with plaster and fixed.
[0009]
The description of the processes from S1 to S11 has been made for the upper jaw part, but the same process is also performed for the lower jaw part. The process using gypsum is also performed for the gypsum embedding process of S3, the gypsum base shaping process of S9, and the articulator mounting process of S11.
[0010]
S13 is an artificial tooth planting process in which a jaw model of a plaster with a wax ridge for the upper jaw and a jaw model of a plaster with a wax ridge for the lower jaw are attached to an articulator, and the biting position of the patient is separately measured, According to the bite position, the height of the upper and lower jaws is cut and adjusted, and artificial teeth are sequentially implanted on the wax. Artificial teeth are implanted by using an articulator and sequentially adjusting so that the artificial teeth for the upper jaw and the artificial teeth for the lower jaw are properly bitten.
