The present invention relates to a nanosilver particle carrying method for carrying nanosilver particles on a denture including a metal bed by induction heating (hereinafter referred to as IH (induction heating)).
従来、義歯床（歯肉）の部分になる床用レジンの材料の素材はアクリル樹脂であり、粉材と液材を規定の分量に計量して混ぜ合わせたものに熱を加えると硬化する性質を持った材料である。
Conventionally, the material of the resin for floors that becomes the part of denture base (gingiva) is acrylic resin, and it has the property of curing when heat is applied to a mixture of powder and liquid materials measured to a specified amount. Material.
近年、歯科技工用の義歯を作成するための床用レジンに対して、抗菌性、防汚性、防臭性が持続する技術が知られている。すなわち、抗菌コーティングのために、マイクロ波照射によってターゲット物体にナノ銀粒子を担持させる技術が知られている。
In recent years, a technique in which antibacterial properties, antifouling properties, and deodorizing properties have been sustained is known for floor resins used to create dentures for dental technicians. That is, a technique for supporting nano silver particles on a target object by microwave irradiation for antibacterial coating is known.
すなわち、この技術によれば、マイクロ波照射によって、義歯に、ナノ銀粒子を離散して担持することにより、優れた抗菌効果を有し、また、咀嚼行為が連続しても、抗菌効果を持続することができるものである。そこで、本件出願人は、先の出願で既に登録となった特許文献１に開示されているように、義歯、あるいは義歯床(歯肉)の部分になる床用レジンを採用し、これらを、例えば透磁率の比較的大きな耐熱性のデンチャーボックス内に入れ、当該義歯を約１５０ｍｌの銀水溶液で浸漬する。そして、デンチャーボックス下部より電源約１０Ｖで一定時間ＩＨを照射して誘導加熱を行うことにより、ナノ銀粒子を離散して義歯に担持させるナノ銀粒子担持方法を提案した。
In other words, according to this technology, the nano-silver particles are carried discretely on the dentures by microwave irradiation, thereby providing an excellent antibacterial effect and maintaining the antibacterial effect even if chewing is continued. Is something that can be done. Therefore, as disclosed in Patent Document 1 already registered in the previous application, the present applicant employs a denture or a denture base resin (gingival) part resin, The denture is immersed in about 150 ml of an aqueous silver solution in a heat-resistant denture box having a relatively high magnetic permeability. And the nano silver particle carrying | support method which carries out the induction heating by irradiating IH with the power supply about 10V for a fixed time from the lower part of a denture box, and carrying | supporting a nano silver particle on a denture was proposed.
しかしながら、上記した特許文献１において、金属床を含む義歯をＩＨにより加熱し、ナノ銀粒子を離散して義歯に担持させる場合、この金属床の大小によって、ＩＨによる温度の上がり方が一様ではなく（図７参照）、金属床の各部分にバラツキが生じ、担持のための一定の温度を保持できず、均一な加熱ができなくなる虞があり、それを改善する必要があった。
However, in Patent Document 1 described above, when a denture including a metal bed is heated by IH and nano silver particles are discretely carried on the denture, the temperature rise by IH is not uniform depending on the size of the metal bed. No (see FIG. 7), there was a variation in each part of the metal floor, a constant temperature for supporting could not be maintained, and there was a possibility that uniform heating could not be performed, and it was necessary to improve it.
そこで、本発明は叙上のような従来存した諸事情に鑑み創出されたもので、ＩＨによる加熱により、金属床を含む義歯に、ナノ銀粒子を離散して担持する際に、各種義歯の金属床の表面積に依存せずに、担持のための一定の温度を保持可能とし、ＩＨの電磁波到達範囲内での義歯の金属床の体積に依存せずに均一な加熱ができるものとしたナノ銀粒子担持方法を提供することを目的とする。
Therefore, the present invention was created in view of various circumstances that existed in the past, and various kinds of dentures were formed when discretely carrying nano silver particles on dentures including a metal bed by heating with IH. Nano that can maintain a constant temperature for loading without depending on the surface area of the metal bed and can perform uniform heating without depending on the volume of the metal bed of the denture within the electromagnetic wave reach of IH An object is to provide a method for supporting silver particles.
上述した課題を解決するために、本発明にあっては、金属床を含む義歯を浸漬した状態で誘導加熱（ＩＨ）を行うことにより、ナノ銀粒子を離散して前記義歯に担持させるナノ銀粒子担持方法であって、ステンレスメッシュかご、もしくはステンレスプレートかごとなって形成された誘導加熱拡散用金属容器に義歯を収容して、誘導加熱拡散用金属容器をデンチャーボックス内に入れ、銀水溶液で義歯を浸漬して、デンチャーボックスに対し誘導加熱（ＩＨ）を行うことを特徴とする。
In order to solve the above-described problems, in the present invention, nanosilver particles are dispersed and supported on the denture by performing induction heating (IH) in a state in which a denture including a metal bed is immersed. A particle carrying method, in which a denture is housed in a metal container for induction heating diffusion formed as a stainless mesh cage or a stainless steel plate cage, the metal container for induction heating diffusion is placed in a denture box, and an aqueous silver solution is used. The denture is immersed and induction heating (IH) is performed on the denture box.
本発明によれば、ＩＨによる加熱により、金属床を含む義歯に、ナノ銀粒子を離散して担持する際に、各種義歯の金属床の表面積に依存せずに、担持のための一定の温度を保持可能とし、ＩＨの電磁波到達範囲内での義歯の金属床の体積に依存せずに均一な加熱ができる。
According to the present invention, when nano silver particles are carried discretely on a denture containing a metal bed by heating with IH, the constant temperature for carrying is not dependent on the surface area of the metal bed of various dentures. Can be maintained, and uniform heating can be performed without depending on the volume of the metal bed of the denture within the electromagnetic wave reachable range of IH.
以下、図面を参照して本発明の実施の一形態を詳細に説明する。
Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.
本実施形態においては、ＩＨ装置によるナノ銀粒子を担持させるデータ採得用の試験対象物（ワーク）として、例えば金属床大（図１参照）、もしくは金属床小を含む義歯（図２参照）を採用している。
In the present embodiment, as a test object (work) for collecting data carrying nano silver particles by an IH device, for example, a metal bed large (see FIG. 1) or a denture including a metal floor small (see FIG. 2). Is adopted.
そして、図３に示すステンレスメッシュかご、もしくは図４に示すステンレスプレートかごとなって各形成された耐食性を有する誘導加熱拡散用金属容器に、金属床大、もしくは金属床小を含む義歯を収容する。
Then, the denture including the large metal floor or the small metal floor is accommodated in the induction heating diffusion metal container having corrosion resistance formed as the stainless steel mesh cage shown in FIG. 3 or the stainless steel plate cage shown in FIG. .
さらに、この誘導加熱拡散用金属容器を、例えば透磁率の比較的大きな耐熱性のデンチャーボックス（図示せず）内に入れ、金属床または義歯を後述する約１５０ｍｌの銀水溶液で浸漬する。
Further, this induction heating diffusion metal container is placed in a heat-resistant denture box (not shown) having a relatively large magnetic permeability, for example, and the metal floor or denture is immersed in about 150 ml of an aqueous silver solution described later.
そして、デンチャーボックスの例えば下部より電源約１０Ｖで一定時間ＩＨを照射する方法を採っている。すなわち、ＩＨ照射による加熱は、デンチャーボックスを磁力発生コイルの上に載せて当該磁力発生コイルに高周波電流（電源約１０Ｖ)を供給することにより、デンチャーボックス全体に所定の時間だけＩＨを照射する。
And, for example, a method of irradiating IH with a power source of about 10 V for a certain time from the lower part of the denture box is adopted. That is, in the heating by IH irradiation, the denture box is placed on the magnetic force generating coil and a high frequency current (power supply of about 10 V) is supplied to the magnetic force generating coil, so that the entire denture box is irradiated with IH for a predetermined time.
すると、当該コイル上に載せられているデンチャーボックス内の銀水溶液及び誘導加熱拡散用金属容器、さらにはワークにうず電流が流れ、当該銀水溶液及び誘導加熱拡散用金属容器、ワーク自体の電気抵抗でジュール熱が発生して自己発熱する。
Then, an eddy current flows through the silver aqueous solution and the induction heating diffusion metal container in the denture box placed on the coil, and further to the work, and the electrical resistance of the silver aqueous solution and the induction heating diffusion metal container and the work itself. Joule heat is generated and self-heating occurs.
ＩＨ照射後、デンチャーボックス内の誘導加熱拡散用金属容器からワークを取り出し、表裏を逆にしてから銀水溶液に再び浸漬し、再度、同じ条件にてＩＨを照射する。こうして、ＩＨの照射によって、銀水溶液中のナノ銀粒子をワークの表裏に離散的に担持させることができる。ここで、ＩＨの照射は、銀水溶液が常温状態（２０℃前後）であることを確認した上で、水溶液の上昇温度を最高でも７５℃程度に保っている為、照射の際にワークが変形することを防ぐことができる。このように、ＩＨの照射が常温で行われるので、ワークの表面に、銀が薄膜を形成するのではなく、ナノ銀粒子となって離散的にワークの表面に担持する。
After the IH irradiation, the work is taken out from the induction heating diffusion metal container in the denture box, the front and the back are reversed, dipped again in the silver aqueous solution, and again irradiated with IH under the same conditions. Thus, the nano silver particles in the silver aqueous solution can be discretely supported on the front and back of the workpiece by IH irradiation. Here, IH irradiation is performed after confirming that the aqueous silver solution is at room temperature (around 20 ° C.), and the rising temperature of the aqueous solution is kept at about 75 ° C. at the maximum. Can be prevented. As described above, since the irradiation with IH is performed at room temperature, silver does not form a thin film on the surface of the workpiece, but is nano-silver particles that are discretely carried on the surface of the workpiece.
銀水溶液は、銀イオンの水溶液であって、例えば、フィチン酸、ポリアクリル酸ナトリウム、炭酸水素ナトリウム、及び、酢酸銀等を含有する安全性の高い銀水溶液５００ｍｌに、アルコール製剤５０ｍｌ～１５０ｍｌ、望ましくは１００ｍｌを混合したものを用いてもよい。また、デンチャーボックスとして、例えば透磁率１．２５６７×１０のマイナス６乗のフッ素樹脂(テフロン:登録商標)製の容器を用いることで、ナノ銀粒子の付着を低減するようにしてもよい。
The aqueous silver solution is an aqueous solution of silver ions. For example, an alcohol preparation of 50 ml to 150 ml is desirably added to 500 ml of a highly safe silver aqueous solution containing phytic acid, sodium polyacrylate, sodium hydrogen carbonate, silver acetate and the like. May be a mixture of 100 ml. In addition, as a denture box, for example, a container made of a fluororesin (Teflon: registered trademark) having a permeability of minus 567 × 10 may be used to reduce the adhesion of nano silver particles.

（４）考察
以上の実験結果から、ステンレスメッシュかごやステンレスプレートかご等の誘導加熱拡散用金属容器をデンチャーボックス内に入れることによってＩＨの出力を安定させることができる。これは、ステンレスメッシュかごよりもステンレスプレートかごの方が、磁束を受ける面積が広いため、わずかに早く温度上昇したものと考えられる。 (4) Discussion From the above experimental results, it is possible to stabilize the output of IH by placing an induction heating diffusion metal container such as a stainless mesh cage or a stainless steel plate cage in the denture box. This is probably because the stainless steel plate cage has a larger area to receive the magnetic flux than the stainless steel mesh cage, so the temperature rises slightly faster.

以上から、金属床を含む義歯を収容した誘導加熱拡散用金属容器をデンチャーボックス内に入れ、銀水溶液で義歯を浸漬して、デンチャーボックスに対し誘導加熱（ＩＨ）を行うというプロセスを経ることで、義歯に離散して担持されたナノ銀粒子は、カンジダの義歯材料への付着を抑制することが確認できた。これにより、金属床を含む義歯へのＩＨ照射によるナノ銀粒子の担持方法において、誘導加熱拡散用金属容器の適用が有効であることが示された。
