A dental magnetic attachment is a denture retainer that, among its many advantages, includes removable connection. The sandwich-type attachment developed by the authors has an attractive force of 6 N at a height of 1.8 mm. Recently, however, dentists have expressed a strong desire for this height to be reduced. It is difficult to meet this requirement, because the attractive force of the sandwich-type structure is proportional to its height. As a solution, we devised a double-sdndwich structure. FEM analysis of the magnetic circuit of the structure shows that a sufficient attractive force will be obtained at a height of only 1.0 mm.The attractive force/size performance of the magnetic circuit is roughly 35% better than that of the current sandwich-structure type.
