We have tried to develop a new magnetic resin-composite material for magnetic attachments of overdentures. The kind of stainless steel and particle size suitable for filler particles of magnetic resin-composite material were determined. An appropriate method for surface treatment of the filler particles was clarified. Several properties of the proposed materials of a resin composition as well as a filler content that were thought to be most appropriate were measured. As the results, the properties including water sorption and corrosion resistance were good enough, however the long-term durability in water was judged to be needed to be improved for clinical use.

我们尝试研制一种新型磁性树脂复合材料用于覆盖义齿磁性附着体。确定了适合磁性树脂复合材料填料颗粒的不锈钢种类和粒径。澄清了填料颗粒表面处理的适当方法。测量了所提出的树脂组合物的材料的几种性质以及被认为是最合适的填料含量。结果表明，包括吸水性和耐腐蚀性在内的性能足够好，但在水中的长期耐久性被认为需要改进以用于临床使用。
