Description
本発明は、例えば歯科医療において使用する印象材を用いて口腔内又は模型材より印象を取得して歯科用石こう模型を製造する際に用いる無色透明歯科用石こう模型艶出し用水溶液に関する。 The present invention relates to an aqueous solution for polishing a colorless and transparent dental gypsum model used for producing a dental gypsum model by obtaining an impression from an oral cavity or a model material using, for example, an impression material used in dentistry.
歯科の臨床で印象採得の手順は、初めに印象材を流動性のある内に専用のトレーに盛り口腔内に挿入して硬化させる。その後、硬化した印象体を取り出し、口腔組織の形状を再現した凹型を得る。このようにして得られた凹型を印象あるいは陰型という。 The procedure for taking an impression in a dental clinic is to first place an impression material in a fluid tray on a dedicated tray, and then insert it into the oral cavity to cure. Thereafter, the cured impression body is taken out to obtain a concave shape that reproduces the shape of the oral tissue. The concave shape obtained in this way is called an impression or a negative shape.
次に、この印象に石こうを流し込み、精密な石こう模型を作製する。様々な種類の印象と石こうを用いて歯列模型を作製した後、これに適合する様々な技工物を作製する。これらの模型をきれいに艶出しできれば、石こう模型を用いて患者に説明する場合にも、患者も気持ちよく見ることができる。 Next, pour gypsum into this impression to make a precise gypsum model. After creating a dentition model using various types of impressions and gypsum, various technical products that fit this are prepared. If these models can be glazed neatly, patients will be able to see comfortably even when explaining to patients using a plaster model.
また、保管中の石こう模型がホコリで表面が汚れてしまうことを防止するためにも、通常は石こう模型をカリ石鹸水溶液（以下、従来艶出し液）に浸漬した後、ガーゼ、ティッシュ等で乾拭きすることで磨いている（例えば、特許文献１等参照）。ここで、使用される石こうは、色調が規定されるものではないが、通常は白色の石こうを利用した清潔感の高い模型が喜ばれる。 Also, in order to prevent the gypsum model being stored from becoming dirty due to dust, the gypsum model is usually dipped in an aqueous solution of potassium soap (hereinafter referred to as a conventional polishing solution) and then wiped dry with gauze, tissue, etc. (For example, refer patent document 1 etc.). Here, the gypsum used is not regulated in color tone, but a model with a high clean feeling using white gypsum is usually appreciated.
従来艶出し液（ソーピング液ともいう）は、カリ石鹸を２０〜４０重量％程度の濃度で水に溶解して、これに香料などを添加して調製される。しかしながら、原料となるカリ石鹸が不純物を多く含む天然原料を使用するため、保管中に茶色又は黄色に着色することが多く、白色の石こう模型が従来艶出し液によって黄色に着色して、清潔感が低下することがある。また、磨き不足により、保管中に石こう模型の表面に残ったカリ石鹸が経時的に変色することもある。 Conventional polishing liquid (also referred to as soaping liquid) is prepared by dissolving potassium soap in water at a concentration of about 20 to 40% by weight and adding a fragrance or the like thereto. However, since potash soap used as a raw material uses natural raw materials that contain many impurities, it is often colored brown or yellow during storage. May decrease. Moreover, due to insufficient polishing, the potash soap remaining on the surface of the plaster model during storage may discolor over time.
カリ石鹸は、よく知られている様に、ヤシ油、パーム核油、パーム油、牛脂等の天然油脂に水酸化カリウムを反応させて製造される。これにより、ラウリン酸、ミリスチン酸、パルミチン酸、オレイン酸などの脂肪酸のカリ塩を主体とするカリ石鹸が得られる。 As is well known, potash soap is produced by reacting potassium hydroxide with natural fats and oils such as palm oil, palm kernel oil, palm oil, and beef tallow. Thereby, a potash soap mainly composed of a potassium salt of a fatty acid such as lauric acid, myristic acid, palmitic acid or oleic acid can be obtained.
歯科技工における従来艶出し液は、上記の通りヤシ油、パーム核油等を原料とするカリ石鹸を水で溶解したものであり、不純物も多いことから、溶解前から多少の黄色又は茶色の着色が避けられないという問題があるが、その利便性故に長く使用されてきた。 Conventional polishing liquid in dental technicians is a solution of potash soap made from coconut oil, palm kernel oil, etc. as described above with water, and because there are many impurities, it is slightly colored yellow or brown before dissolution. However, it has been used for a long time because of its convenience.
従来艶出し液の代替品としてナトリウム石鹸が使用されることがあるが、固形で溶解しにくいため、沈殿物が出やすい。また、ナトリウム石鹸は一部手作りで使用されることがあるだけで、従来艶出し液として一般的な代替品とはなっていない。 Conventionally, sodium soap may be used as an alternative to the polishing liquid, but it is difficult to dissolve in a solid form, so precipitates are likely to appear. Also, sodium soap is only partially used by hand, and has not been a common substitute for conventional polishing liquids.
よって、長期間保管しても着色がない無色透明な歯科用石こう模型艶出し用水溶液であって、長期間保管後に石こう模型に塗布しても石こう模型の表面に着色が発生せず、また、塗布後の経時的な変色も防止されており艶出しの状態を維持することができる無色透明歯科用石こう模型艶出し用水溶液の開発が求められている。 Therefore, it is a colorless and transparent dental plaster model polishing aqueous solution that is not colored even after long-term storage, and no coloration occurs on the surface of the plaster model even if it is applied to the plaster model after long-term storage, There is a need for the development of an aqueous solution for polishing a colorless and transparent dental plaster model that can prevent discoloration with time after application and can maintain a polished state.
上記のように、歯科技工で利用される石こう模型は、艶出し液と呼ばれるカリ石鹸水溶液に浸漬後、ガーゼ等で磨くことで、艶のある模型にできるが、天然油脂原料を利用したカリ石鹸は不純物を含むため、艶出し液の保管中あるいは石こう模型への塗布後に着色することがある。 As described above, the gypsum model used in dental technicians can be made into a glossy model by dipping in an aqueous solution of potash soap called a polishing liquid and then polishing with gauze. Since it contains impurities, it may be colored during storage of the polishing liquid or after application to the stone model.
本発明の目的は、長期間保管しても着色がない無色透明な歯科用石こう模型艶出し用水溶液であって、長期間保管後に石こう模型に塗布しても石こう模型の表面に着色が発生せず、また、塗布後の経時的な変色も防止されており艶出しの状態を維持することができる無色透明歯科用石こう模型艶出し用水溶液を提供することにある。 An object of the present invention is a colorless and transparent dental plaster model polishing aqueous solution that is not colored even when stored for a long period of time. Even if it is applied to the plaster model after long-term storage, the surface of the plaster model does not color. Further, it is an object of the present invention to provide a colorless and transparent dental plaster model glazing aqueous solution that can prevent discoloration with time after application and can maintain the glazing state.
本発明者は、上記目的を達成すべく鋭意研究を重ねた結果、ラウリン酸カリウム及びミリスチン酸カリウムの少なくとも１種を特定量含有する艶出し用水溶液によれば、上記目的を達成できることを見出し、本発明を完成するに至った。 As a result of intensive studies to achieve the above object, the present inventor has found that the above object can be achieved according to a polishing aqueous solution containing a specific amount of at least one of potassium laurate and potassium myristate, The present invention has been completed.

以下、本発明の無色透明歯科用石こう模型艶出し用水溶液及びスプレー剤について詳細に説明する。 Hereinafter, the colorless transparent dental plaster model polishing aqueous solution and spray agent of the present invention will be described in detail.
無色透明歯科用石こう模型艶出し用水溶液
本発明の無色透明歯科用石こう模型艶出し用水溶液は、ラウリン酸カリウム及びミリスチン酸カリウムの少なくとも１種を有効成分として、有効量含有する。
The colorless and transparent dental plaster model polishing aqueous solution of the present invention contains an effective amount of at least one of potassium laurate and potassium myristate as an active ingredient.
本発明の無色透明歯科用石こう模型艶出し用水溶液は、ラウリン酸カリウム及びミリスチン酸カリウムの少なくとも１種を含有することにより、長期間保管しても着色がない無色透明な状態を維持することができる。また、本発明の無色透明歯科用石こう模型艶出し用水溶液を長期間保管後に石こう模型に塗布しても石こう模型の表面に着色が発生せず、また、塗布後の経時的な変色も防止されており艶出しの状態を維持することができる。 The colorless and transparent dental gypsum model polishing aqueous solution of the present invention contains at least one kind of potassium laurate and potassium myristate, and can maintain a colorless and transparent state without coloring even when stored for a long period of time. it can. Further, even when the colorless and transparent dental plaster model polishing aqueous solution of the present invention is applied to the plaster model after long-term storage, the surface of the plaster model is not colored, and discoloration with time after the application is prevented. The glossy state can be maintained.
本発明の無色透明歯科用石こう模型艶出し用水溶液が含有するラウリン酸カリウム及びミリスチン酸カリウムの製造方法は限定されず、例えば、ヤシ油及び／又はパーム核油を加水分解してできた脂肪酸を分留精製し、水酸化カリウムで中和することにより製造される。よって、本発明の無色透明歯科用石こう模型艶出し用水溶液は、従来艶出し液で利用されてきたカリ石鹸水溶液とは全く異なる原料を利用する。 The method for producing potassium laurate and potassium myristate contained in the colorless and transparent dental plaster model polishing aqueous solution of the present invention is not limited. For example, a fatty acid produced by hydrolyzing palm oil and / or palm kernel oil is used. It is produced by fractional purification and neutralization with potassium hydroxide. Therefore, the colorless and transparent dental plaster model polishing aqueous solution of the present invention uses a completely different raw material from the potassium soap aqueous solution conventionally used in the polishing liquid.
本発明の無色透明歯科用石こう模型艶出し用水溶液において、ラウリン酸カリウム及びミリスチン酸カリウムの少なくとも１種の含有量は５〜４０重量％であり、１０〜２０重量％であることが好ましい。ラウリン酸カリウム及びミリスチン酸カリウムの少なくとも１種の含有量が５重量％未満では艶出し効果が少なく、４０重量％を超えると水溶液というよりペーストに近くなり、艶出し処理が煩雑になる。 In the colorless and transparent dental plaster model polishing aqueous solution of the present invention, the content of at least one of potassium laurate and potassium myristate is 5 to 40% by weight, and preferably 10 to 20% by weight. When the content of at least one of potassium laurate and potassium myristate is less than 5% by weight, the polishing effect is small, and when it exceeds 40% by weight, it becomes closer to a paste rather than an aqueous solution, and the polishing process becomes complicated.
本発明の無色透明歯科用石こう模型艶出し用水溶液は、上記の有効成分のほか、本発明の効果に影響を与えない範囲で、歯科用石こう模型艶出し用水溶液に含めることができる公知の成分を適宜含んでもよい。そのような成分の例は、例えば、防腐剤、界面活性剤、酸化防止剤及びＥＤＴＡである。 The colorless and transparent dental gypsum model polishing aqueous solution of the present invention is a known component that can be included in the dental gypsum model polishing aqueous solution in addition to the above-mentioned effective components, as long as the effect of the present invention is not affected. May be included as appropriate. Examples of such components are, for example, preservatives, surfactants, antioxidants and EDTA.
本発明の無色透明歯科用石こう模型艶出し用水溶液の溶媒としては水であり、通常は精製水を使用する。 The solvent for the colorless and transparent dental plaster model polishing aqueous solution of the present invention is water, and purified water is usually used.
本発明の無色透明歯科用石こう模型艶出し用水溶液は、従来艶出し用水溶液の使用方法と同様に、石こう模型を艶出し用水溶液に浸漬してからガーゼ等で磨くことで、艶のある石こう模型にできる。石こう模型を本発明の無色透明歯科用石こう模型艶出し用水溶液に浸漬する時間は限定的ではないが、通常３０秒間程度で充分である。 The colorless and transparent dental gypsum model polishing aqueous solution of the present invention is a glossy gypsum by dipping the gypsum model in the polishing aqueous solution and polishing it with gauze or the like in the same manner as in the conventional use of the polishing aqueous solution. Can be a model. The time for immersing the gypsum model in the colorless and transparent dental gypsum model polishing aqueous solution of the present invention is not limited, but usually about 30 seconds is sufficient.
また、本発明の無色透明歯科用石こう模型艶出し用水溶液は、ノズル付きのスプレー用容器に封入されたスプレー剤として使用することができる。 Moreover, the colorless and transparent dental gypsum model polishing aqueous solution of the present invention can be used as a spray agent sealed in a spray container with a nozzle.
本発明の無色透明歯科用石こう模型艶出し用水溶液をノズル式のスプレーにより石こう模型の表面に吹き付けてから、ガーゼ等で磨くことで、短時間で容易に艶のある石こう模型を形成することができる。スプレー方式については、従来艶出し用水溶液では沈殿物が生じやすいためにノズルが詰まりやすく利用出来ないと考えられてきたが、本発明の無色透明歯科用石こう模型艶出し用水溶液は保管時の沈殿の発生が抑制されているためノズルの詰まりを回避してスプレー方式で利用することができる。 It is possible to easily form a glossy gypsum model in a short time by spraying the colorless and transparent aqueous solution for polishing a plaster model of the present invention onto the surface of the gypsum model by spraying a nozzle and then polishing it with gauze or the like. it can. As for the spray method, it has been thought that the conventional polishing aqueous solution for glazing is not likely to be used because the precipitate is likely to be clogged, but the colorless transparent dental plaster model glazing aqueous solution of the present invention is a precipitate during storage. Since generation | occurrence | production of this is suppressed, clogging of a nozzle can be avoided and it can utilize by a spray system.
本発明で利用できるスプレー方式には次のような利点がある。つまり、従来法では艶出し用水溶液に石こう模型を５分間以上浸漬する必要があるが、浸漬時に石こう模型に艶出し用水溶液が吸収されるため消費量が多くなる（１０％水溶液で約４ｇ）。これに対して、本発明で利用できるスプレー方式では、泡によって模型表面に処理液を保持できるために、消費量を少なく（１０％水溶液噴霧で約２ｇ）することができる。更に、従来法の浸漬では艶出し不要あるいは艶出ししたくない部分も処理してしまう他、浸漬中に石こう模型の表面が溶解してカルシウムイオンを放出するため、不溶性のカルシウム石鹸が沈殿として析出して、使用回数の増加に伴い粘調な白濁液となって使用感が悪化するという問題があったが、スプレー方式ではこのような問題も防止できる。 The spray system that can be used in the present invention has the following advantages. That is, in the conventional method, it is necessary to immerse the gypsum model in the polishing aqueous solution for 5 minutes or more, but the consumption increases because the polishing aqueous solution is absorbed into the gypsum model at the time of immersion (about 4 g in a 10% aqueous solution). . On the other hand, in the spray system that can be used in the present invention, since the treatment liquid can be held on the model surface by the foam, the consumption can be reduced (about 2 g by 10% aqueous solution spray). In addition, the dipping of the conventional method treats parts that do not need to be polished or does not want to be polished, and the surface of the gypsum model dissolves and releases calcium ions during dipping, so that insoluble calcium soap precipitates. As the number of times of use increases, there is a problem that it becomes a viscous cloudy liquid and the feeling of use deteriorates. However, such a problem can be prevented by the spray method.
また、本発明の無色透明歯科用石こう模型艶出し用水溶液を利用することで、短時間で容易に艶のある歯科用石こう模型を製作できるため、本発明の無色透明歯科用石こう模型艶出し用水溶液で処理した石こう模型の耐水性を向上させたり、従来の様に浸漬する必要が無いため、アクリルレジン義歯製作時の石こう対レジンの分離剤としての効果を得るための用途にも利用できる。 Further, since the glossy dental plaster model can be easily produced in a short time by using the colorless and transparent dental plaster model polishing aqueous solution of the present invention, the colorless and transparent dental plaster model for polishing the present invention Since it is not necessary to improve the water resistance of the gypsum model treated with an aqueous solution or to immerse it as in the conventional case, it can be used for the purpose of obtaining an effect as a separating agent for gypsum and resin when producing an acrylic resin denture.
