本発明は、空気中の酸素によって重合阻害を受は易い歯
科用レジンの被菫剤に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coating agent for dental resins that is susceptible to polymerization inhibition by oxygen in the air.
［従来の技術］

用した重合硬化型の樹脂が汎用されている。[Prior Art] Composite resins, resin cements, etc. are known as dental resin restorative materials (hereinafter simply referred to as restorative materials), and polymerization-curing resins using acrylic monomers are known as the materials for these. It is commonly used.
アクリル系モノマーは、空気中の酸素によって重合硬化
が阻害されるという特性を有することが知られている。Acrylic monomers are known to have the property that polymerization and curing are inhibited by oxygen in the air.

含まれる石英等の高硬度のフィラーの為に切削が困難で
あり、思い通りの形態を付与することは不可能である。Therefore, when using a restorative material made of acrylic monomer, unless some treatment is applied, the polymerization reaction will be inhibited by oxygen in the air and a polymerization inhibition layer will be formed on the surface of the restorative material. 30 to 70 for composite resins and sealants for anterior teeth or children.
JLm thickness, 80 for composite resin for molars
The polymerization inhibiting layer having a thickness of about 150 gm is observed. Therefore, in daily clinical practice, it is necessary to fill the composite resin to give it a shape, and then remove the polymerization-inhibiting layer on the surface after the polymerization reaction is completed. Therefore, even though the shape has already been imparted, the surface morphology after removing one polymerization inhibiting layer becomes uncertain, and the problem arises that the required height cannot be secured. To solve this problem, it may be possible to fill the composite resin in excess of the amount required to impart shape, remove the polymerization inhibition layer after curing the composite resin, and then polish the cured surface to impart shape. However, the high hardness filler such as quartz contained in the composite resin makes it difficult to cut and it is impossible to give it the desired shape.

は適していない。Alternatively, in order to prevent the formation of the polymerization inhibition layer,
In some cases, a method is adopted in which the surface of the filled composite resin is pressure-contacted with strips to shield the surface from air, thereby preventing the formation of a polymerization-inhibiting layer on the surface of the composite resin. It has the disadvantage of causing great pain to patients until it is completed, and is not suitable for widespread use.
［発明が解決しようとする問題点］

に防ぐことはできてい広い。[Problems to be Solved by the Invention] Furthermore, with the technique using strips, it is not possible to reliably press the strips against a composite resin with a complex surface shape, and it is difficult to completely form a single polymerization inhibition layer. It is possible to prevent it from being wide.

結果１本発明を完成するに至った。The inventors of the present invention have conducted extensive research to solve the above-mentioned problems.
We obtained a guideline that the formation of the polymerization-inhibiting layer could be prevented by applying a paste-like coating to the surface of a repair material such as a composite resin to shield the surface from oxygen in the air. Further, as a result of studying the specific means, the present invention has been completed.
即ち本発明の目的は、修復材料の表面に重合阻害層が形
成されるのを防止する為に用いられる歯科用レジンの表
面被覆剤を提供することである。That is, an object of the present invention is to provide a surface coating agent for dental resin that is used to prevent the formation of a polymerization-inhibiting layer on the surface of a restorative material.
［問題点を解決する為の手段］
本発明は、高分散性の二酸化珪素１０〜５０重量部を分
散媒５０〜９０重量部中に分散させてペースト状とした
点に要旨を有するものである。[Means for Solving the Problems] The gist of the present invention is that 10 to 50 parts by weight of highly dispersible silicon dioxide is dispersed in 50 to 90 parts by weight of a dispersion medium to form a paste. .

表面から容易に除去できることが必要であり′、これら
の点に鑑み、既述の組成を必須要件と定めた。[Function] In order to prevent the formation of a polymerization inhibiting layer on the surface layer of the repair material, it is necessary to prevent the surface of the repair material from being exposed to the air. Therefore, in the present invention, a configuration is adopted in which a paste-like coating agent is applied to the surface of the repair material to shield the surface of the repair material from oxygen in the air. Furthermore, it is necessary that the coating agent be easily removed from the surface of the restorative material after the curing of the restorative material is completed, and in view of these points, the above-mentioned composition was determined as an essential requirement.
本発明の被覆剤に含まれる高分散性二酸化珪素は、臨床

覆剤の流動性が過大となり、被覆剤を修復材料の表面に
塗布したときの表面被包性が低下し表面が部分的に露出
した状態となり、上記目的を達成することができない。The highly dispersible silicon dioxide contained in the coating material of the present invention is added for the purpose of imparting appropriate viscosity to the coating material in order to improve clinical operability. That is, if the mixing ratio of silicon dioxide is less than 10 parts by weight, the fluidity of the coating agent becomes excessive, and when the coating agent is applied to the surface of the restoration material, the surface encapsulation property decreases and the surface becomes partially covered. This results in an exposed state and the above purpose cannot be achieved.
また二酸化珪素の混合割合が５０重量部を超える場合に
は粘稠性が必要以上に増大し、臨床における作業性に劣
り、或は気泡の巻き込みを生じ易くなり不適である。二
酸化珪素の最も好ましい混合割合は、被覆剤１００重量
部に対し１５〜３０重量部程度である。Furthermore, if the mixing ratio of silicon dioxide exceeds 50 parts by weight, the viscosity increases more than necessary, resulting in poor clinical workability or easy entrainment of air bubbles, which is unsuitable. The most preferable mixing ratio of silicon dioxide is about 15 to 30 parts by weight per 100 parts by weight of the coating material.
分散媒としては、水等による洗浄で容易に除去できると

いてもちとも重要な役割を果す、尚分散媒が５０重量部
未満では粘稠性が過大となり、９０重量部超では流動性
が過大となる。As the dispersion medium, water-soluble solvents such as glycerin and ethylene glycol are selected because they can be easily removed by washing with water. If the medium is less than 50 parts by weight, the viscosity will be too high, and if it exceeds 90 parts by weight, the fluidity will be too high.

即ち被覆剤を修復材料の表面に塗布する際に、被覆剤と
修復材料の表面との間に少量の空気が介在することは。The basic structure of the present invention is as described above, and a paste-like coating material is provided by dispersing highly dispersible silicon dioxide in a dispersion medium. Sodium, sodium thiosulfate, sodium bezenesulfinate, etc. may be added.
That is, when the coating is applied to the surface of the restorative material, a small amount of air may be present between the coating and the surface of the restorative material.
テクニック面から見ても不可避と言い得るものであり、
この様な介在空気を上記還元性物質によって消失せしめ
ることは重合阻害層の形成を防止する上で合目的なこと
である。尚還元性物質の配合量は０．５〜１０重量部程
度が推奨される。From a technical point of view, it can be said that this is unavoidable.
Eliminating such intervening air with the reducing substance is useful in preventing the formation of a polymerization-inhibiting layer. It is recommended that the reducing substance be added in an amount of about 0.5 to 10 parts by weight.
その他、修復材料と被覆剤とを色によって識別する為に
、被覆剤中に適量の着色剤が添加されてもよいのは勿論
である。Of course, an appropriate amount of coloring agent may be added to the coating material in order to distinguish the restorative material from the coating material by color.
尚ペースト状とする際に、被覆剤中に空気を含まない様
にするには、低圧力雰囲気中で脱泡処理を施せばよい。In order to prevent air from being contained in the coating material when it is made into a paste form, defoaming treatment may be performed in a low pressure atmosphere.

面を硬化させるような用途に用いることもできる。The above description has been directed exclusively to composite resins. On the other hand, to add a supplementary explanation regarding resin cement, in recent years, acrylic thread has been used as a luting material for dental cast restorations, and it is possible to make the film thickness sufficiently thin by adding ultrafine particle filler, and also has excellent tooth bonding properties. Resin cement using Tsumar has been developed. One of the characteristics of this resin cement is that it can absorb approximately 3307 mw by oxygen in the air.
It is mentioned that a certain degree of polymerization inhibition layer is formed. In the case of this resin cement, unlike in the case of composites and resins, there is no need to give it a shape, so after removing the excess gushing resin cement, the coating material of the present invention is applied to the exposed surface of the resin cement. It can also be used for purposes such as hardening the surface.

けるレジンの硬化が良好に進行したことが理解される。The area around the area where the coating agent was applied on the thus cured resin was observed using an optical microscope. As a result, a polymerization inhibiting layer was observed on the surface of the resin that was in contact with air, with a width of approximately 80 lumens. On the other hand, the polymerization inhibiting layer was not observed at all on the surface of the resin coated with the coating agent, and the resin was completely polymerized and cured. From these results, it is understood that by applying the coating agent to the surface of the resin, the curing of the resin progressed favorably at that location.
