A study about optics characteristic of Maxillofacial Epenthesis materials

用于颌面修复材料的硅树脂，直到最近才采用国外产品。但是，由于这种国外产品在日本已经没有了，所以新的硅树脂产品的开发正在日本进行。因此，有必要对国外已使用的硅辞去与新开发的硅辞去的特性进行比较。结果表明，即使使用相同数量的硅树脂和颜料，旧硅树脂和新硅树脂的颜色也会有差异。

For silicon resin used for maxillofacial prosthesis materials, a foreign products had been used until recently. However, since this foreign products have become unavailable in Japan, the development of new silicon resin product is ongoing in Japan. Thus, it was necessary to compare the characteristics between previously used foreign silicon resign and newly developed one.The results suggested that color difference was observed between previously used silicon resin and newly developed one even the same amounts of silicon resin and pigment were used.
