Development of Resin for Crown and Bridge with a Higher Toughness

研究成就的大纲：我们已经尝试开发由二甲基丙烯酸酯或环氧单体和硅组成的新材料，在维护美学和作为皇冠和桥梁的生长的同时，抵抗了大量力量。本研究的特性是为了用更高的硬度开发一种材料。用梯度性质的材料构造：粒子强化复合物（PRP）由光固化的二甲基丙烯酸酯和二氧化硅粒子组成的树脂，被用于顶层表面，因为它是一种美学和操作性。纤维强化树脂（FRP）包括硅纤维和环氧树脂，已应用于核心材料。结果：1。树脂基质的改进......一种新颖的二甲基丙烯酸酯和环氧单体是设计和合成的。这些单体不能有二苯酚A，作为二丙烯酸酯和环氧树脂分子的主要链条。这些聚合物有更高的烦恼.....。弹性模块中梯度材料的设计......要在PRP和FRP之间制造出良好的粘合剂，二甲基丙烯酸酯单体的光聚合化和环氧树脂单体的热聚合化在两个单体的存在中进行了测试。两个个体的聚合化过程是通过热分析进行分析的。环氧树脂在110-130时被热固化了[C]后的dimethacrylate单体被光固化了。我们可以用更高的理智来开发皇冠和桥梁树脂。

Outline of the study achievements : We tried to develop of the new material comprised of dimethacrylate or epoxy monomer and silica, resists the occulisional force while maintaining aesthetics and an operability as the resin for Crown and Bridge. The characteristic of this study is to develop a material with a higher toughness.Construction of the material with a gradient property : The particle reinforced composite (PRP) resin comprised of the photo-curing dimethacrylate and silica particle, was used for the top surface because the it has an aesthetics and an operability. The fiber reinforced resin (FRP) comprised of the silica fiber and the epoxy resin with toughness was applied for core material.Results :1. The improvement of resin matrix・・・・・・The novel dimethacrylate and epoxy monomers were designed and synthesized. These monomers do not have a bis-phenol A as a main chain in the dimethacrylate and epoxy resin molecule. These polymers had a higher toughness.2. The design of the gradient material in the elastic modulus・・・・・・To make a good adhesion between the PRP and FRP, the photo-polymerization of dimethacrylate monomer and the heat-polymerization of epoxy resin monomer were examined in the presence of both monomers. The process of the polymerization of both two monomers were analyzed by the heat analysis. The epoxy resin was heat-cured at 110-130ﾟC after the dimethacrylate monomer was photo-cured.3. We could develop the crown and bridge resin with a higher toughness.
