【発明の詳細な説明】
義歯床用材料としては、レジン系および金属が使用され
ているが、義歯床は衆知のごとく製作工程が多岐にわた
るばかりでなく、複雑であるため、Σ口腔に精度よく適
合するものを得ることは困難である。[Detailed Description of the Invention] Resin-based materials and metals are used as materials for denture bases, but as is well known, denture bases not only require a wide variety of manufacturing processes but also are complex, so they cannot be made with high precision in the Σ oral cavity. It is difficult to obtain a suitable one.
一方、顎提および顎骨などの異常形態がある場合には、
床は口腔粘膜への適合性が悪くなり、また、床の機械的
刺激によつて粘膜面への潰瘍形成 ３および粘膜の肥厚
などの弊害が生じる。On the other hand, if there is an abnormal shape of the chin and jawbone,
The floor becomes less compatible with the oral mucosa, and mechanical irritation of the floor causes problems such as ulcer formation on the mucosal surface and thickening of the mucous membrane.
上述した組成物を用いて床のライニングを行なうことに
よつて、粘膜稀薄部および肥厚部に対する咬合性の緩衝
、床辺縁部の粘膜面への密着および辺縁封鎖による維持
力の向上などの効果が得ら ３０れるだけでなく、外科
的処置後の義歯床の維持安定および顎鋭縁部の圧迫疼痛
の緩和などの大きな効果が得られる。By lining the floor with the above-mentioned composition, it is possible to achieve occlusal cushioning for thin and thickened areas of the mucosa, adhesion of the edge of the floor to the mucosal surface, and improved maintenance by sealing the edge. Not only is it effective, but it also has great effects such as maintaining and stabilizing the denture base after surgical procedures and alleviating pressure pain at the acute edge of the jaw.
すなわち、顎提に対する義歯床の適合性が増大するだけ

圧の分散緩和の作用効果が生じ、骨組織の再生が容易に
行なわれる。義歯床の裏装材としては、現在、主として
アクリル系およびシリコーン系の材料が用いられている
が、これらの材料は、口腔内の環境では耐久性に乏しい
。すなわち、温度変化が大きく、湿度１００％に近い状
態で荷重が加わるため、耐水性および接着性が低下する
とともに、変色し、さらに、脆弱化するため、長時間の
使用に耐え得ない欠点がある。上記組成物は、これらの
難点を解決するものであるが、エポキシ樹脂としては、
エポキシ当量３００〜５００、粘度４００〜９００ＣＰ
Ｓ（２５℃）、ポリサルファイドポリマーは、平均分子
量２０００〜４０００を使用することができるが、好ま
しくは４０００のものを使用した場合である。That is, not only does the conformity of the denture base to the jaw holder increase, but also the discomfort is reduced, and the effect of alleviating the dispersion of occlusal pressure applied to the base occurs, thereby facilitating the regeneration of bone tissue. Currently, acrylic and silicone materials are mainly used as lining materials for denture bases, but these materials have poor durability in the intraoral environment. In other words, since the load is applied under conditions of large temperature changes and humidity close to 100%, water resistance and adhesion deteriorate, discoloration occurs, and the material becomes brittle, making it unsustainable for long-term use. . The above composition solves these difficulties, but as an epoxy resin,
Epoxy equivalent: 300-500, viscosity: 400-900CP
S (25° C.), polysulfide polymer having an average molecular weight of 2,000 to 4,000 can be used, but preferably one having an average molecular weight of 4,000 is used.
また、ポリアミド樹脂は、アミン価（ＫＯＨのミリグラ

させる。Further, the polyamide resin has an appropriate amine value (milligrams of KOH) of 300±50. On the other hand, 10 to 20 parts of a suitable filler, such as diatomaceous earth or fine silica stone, is added to the above-mentioned suitable mixture to adjust the viscosity and put into practical use.
しかし、前述した組成物以外の場合には、硬化物の吸水

、その性質を具体的に表示する。However, in the case of compositions other than those described above, the water absorption rate of the cured product increases, the hardness, tensile strength, and adhesive strength decrease significantly, and furthermore, the elasticity decreases, so that it is not practical. It is also possible to use some peroxide and guanidine curing agents as substitutes for polyamide resins, but if these are used, there is a concern that they may be harmful to the human body. Next, typical examples will be described and their properties will be specifically shown.
