DEVELOPMENT OF MERCURY-FREE AMALGAM DENTAL FILLINGS

描述：(改编自申请者的摘要)有必要开发 牙科银汞合金材料可以继续利用 汞基汞合金，低成本，低技术敏感性，以及 经久耐用。这项研究将开发新的牙科银汞合金充填材料 基于公认的银、锡和锌汞齐元素的材料，不含 汞的使用。这项研究将制定过程原则，以形成 允许冷焊、固态时效硬化的非平衡相， 尺寸稳定性和对牙齿结构的粘附性使新材料 与现在的汞合金牙科几乎有同样的好处 填充物。 建议的商业应用：不可用

DESCRIPTION: (adapted from applicant's abstract) There is a need to develop dental amalgam materials that could continue to utilize the benefits of mercury-based amalgam, in terms of low cost, low technique sensitivity, and long term durability. This research will develop new dental amalgam filling materials based on well-accepted silver, tin and zinc amalgam elements without the use of mercury. This research will develop process principles to form non-equilibrium phases allowing cold welding, solid state age hardening, dimensional stability and adhesion to tooth structure so that the new materials would have nearly the same benefits as the present mercury amalgam dental fillings.
