〔産業上の利用分野〕
本発明は、動揺歯の固定や前歯部欠損歯補綴に使用する
補綴修復用の歯科用複合金属材料に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a dental composite metal material for prosthetic restoration, which is used for fixing loose teeth and prosthetics of missing anterior teeth.
［従来の技術］
従来、欠損歯や歯周病による動揺歯の治療は、例えば前
者の場合、歯欠部分に人工歯を媒体として隣接歯に接着
して架橋する所謂アトヒユージョンブリッジ、クラウン
ブリッジやクラスプのような形態を採るとか、あるいは
後者の場合には、接着性レジンで両側の健全歯に連結固
定する等の方法がある。[Prior Art] Traditionally, treatments for missing teeth or loose teeth due to periodontal disease have been, for example, in the former case, using so-called atfusion bridges or crown bridges in which artificial teeth are used as a medium to bond and bridge the missing teeth to adjacent teeth. Alternatively, in the latter case, it may be connected and fixed to healthy teeth on both sides using adhesive resin.
このような従来技術によると、前者の隣接歯にセメント
で接着する架橋法は、両側の支持歯を切削し、全部を被
覆歯とすることが多いために健全歯の寿命が短縮される
問題がある。According to such conventional techniques, the former method of bridging, which involves adhering adjacent teeth with cement, involves cutting the supporting teeth on both sides and often covering the entire tooth, which has the problem of shortening the lifespan of healthy teeth. be.
また、良好な適合が得られないとその周辺部は不潔域と
なって歯周病患の病因を招来し、補綴物を浮き上がらせ
、適切な咬合状態が得られないという問題がある。In addition, if a good fit is not obtained, the surrounding area becomes unclean, causing periodontal disease, causing the prosthesis to stand out, and causing problems in that an appropriate occlusal condition cannot be obtained.
つぎに、後者の接着性レジンで両側の支持歯に連結固定
する方法は、普通咬合時は５０Ｋｇ以上の強力な力が加
わるが、歯牙および歯肉の緩衝作用によって適切な咬合
は行われるが、この方法は接着性レジンで両側の支持歯
に強固に固定されるために力が分散されず、同一個所に
集中的な応力が掛かる問題がある。その結果、接合個所
の一部に経時的疲労が起こって、支台歯の揺動や接合個
所の破損が生じたり、歯肉の炎症を助長する問題がある
。Next, with the latter method of connecting and fixing to supporting teeth on both sides using adhesive resin, a strong force of 50 kg or more is applied during normal occlusion, but proper occlusion is achieved due to the cushioning effect of the teeth and gums. This method has the problem that the force is not dispersed because it is firmly fixed to the supporting teeth on both sides using adhesive resin, and stress is concentrated in the same area. As a result, fatigue occurs over time in a part of the bonded area, causing problems such as rocking of the abutment tooth, damage to the bonded area, and promoting inflammation of the gums.
そこで、近時、Ｎｉ−Ｃｒの金属網と金属板の複合材に
よるプレートを、欠損歯や動揺歯等の治療歯とその隣接
歯の古血倒の所定の形状に圧印法によって形成し、その
形成したプレートを接着性レジンで連結固着する方法が
あり、咬合時の応力の分布が良いという特徴がある。Therefore, recently, a plate made of a composite material of Ni-Cr metal net and metal plate is formed into a predetermined shape of the old blood of the tooth to be treated, such as a missing tooth or a loose tooth, and the adjacent tooth by the coining method. There is a method of connecting and fixing the formed plates with adhesive resin, which has the advantage of good stress distribution during occlusion.
ところが、このプレートは、金属網と金属板が強固に密
着している必要があり、しかも歯の古血倒の所定の形状
に形成できなければならならず、さらに、歯との密着性
、加工性および保持強度も良くなければならないが、そ
れらの点に問題がある。However, this plate requires a strong adhesion between the metal mesh and the metal plate, and it also needs to be able to be formed into a predetermined shape that matches the teeth. The properties and retention strength must also be good, but there are problems with these points.
その大きな原因は、金属網と金属板の素材の特性と、金
属網の構成にありその構成は網の交差部では一方の線材
は浮いてしまい、凹凸も大きいために密着性が悪いもの
である。The main reason for this is the characteristics of the materials used for the metal mesh and metal plate, and the structure of the metal mesh.The structure is such that at the intersection of the meshes, one of the wires floats, and the unevenness is large, resulting in poor adhesion. .
〔課題を解決する為の手段］

重ね合わせ、６００°Ｃ以上の温度で熱間接合して冶金
的に一体化したことを特徴とする。[Means for Solving the Problems] The present invention provides a dental composite metal material in which a metal mesh is bonded to one side of a metal plate, Au10 to 25 wt%, P d 1
5-35wt%, Ag45-70wt% and further Sn
An alloy with a composition range of 0.1 to 5 wt% of one or two of In and In is added to form an alloy plate with a thickness of 0.05 to 0.5 mm, and an expanded mesh of an alloy with the above composition range is layered on one side of the plate. They are characterized by being metallurgically integrated by hot joining at a temperature of 600°C or higher.
以上の構成によると、上記複合金属材料を欠損歯や動揺
歯等の治療歯とその隣接歯の古血倒の所定の形状に形成
し、エクスパンド網を歯の雪面側に接着性レジン等で密
着させることにより治療歯を補綴修復することができる
ことになる。According to the above configuration, the composite metal material is formed into a predetermined shape of the tooth to be treated, such as a missing tooth or a loose tooth, and its adjacent teeth, and the expanded mesh is attached to the snow surface side of the tooth using an adhesive resin or the like. By bringing them into close contact, it is possible to perform prosthetic restoration of the treated tooth.
ここで、合金成分をＡｕ−Ｐｄ−ＡｇにＳｎとＩｎの一

ぞれの量を限定した理由は、Ａｕ−Ｐｄ−Ａｇ合金は従

により接着性レジンによる歯との接合を良くすることが
でき、その添加量が０．１ ｗ ｔ％未満ではその接合
を強化させる効果が少なく、５ｗｔ％を超えると口腔内
における耐蝕性が問題となるためである。Here, the reason for limiting the amount of each alloy component as a quaternary or quinary alloy consisting of Au-Pd-Ag and one or two of Sn and In is that Au-Pd-Ag alloy has traditionally been used as a dental material. It is a dental material that is used as a dental material with excellent formability, workability, support strength, and durability.It also has good bonding workability between the alloy plate and the expander network, but it also contains Sn and/or In. By adding , it is possible to improve the bonding between the adhesive resin and the teeth. If the amount added is less than 0.1 wt%, the effect of strengthening the bond is small, and if it exceeds 5 wt%, the corrosion resistance in the oral cavity is reduced. This is because it becomes a problem.
また、基材の厚さを０．０５〜０．５１１Ｉｆｆｌとし
た理由は、０．０５ａａａ未満では欠損歯または動揺歯
を支える強度が不足するためであり、０．５１１ＩＩｎ
を超えると補綴修復加工が難しくなるためである。The reason why the thickness of the base material is set to 0.05 to 0.511Iffl is that if it is less than 0.05aaa, it lacks the strength to support missing teeth or moving teeth, and 0.511Iffl
This is because the prosthetic restoration process becomes difficult if it exceeds this value.
