Zusammenfassung:	To develop a magnet type denture attachment having high adsorption power of about 800 g, and a small thickness of 0.5 mm-1 mm, and capable of applying a bridge using a pulped tooth as an abutment tooth.SOLUTION: A shield plate of a magnet structure comprises multiple 18Cr-8 Ni-based stainless magnets having residual magnetization of 6 kG or more. A cap has multiple cup-shaped hole parts, and a permanent magnet is placed therein respectively, to thereby improve magnetic attraction power by complex magnetization.SELECTED DRAWING: Figure 3 【課題】８００ｇ程度の高い吸着力と、０．５ｍｍ～１ｍｍの小さな厚みを有し、有髄歯を支台歯とするブリッジの応用を可能な磁性アタッチメントを開発する。【解決手段】磁石構造体のシールドプレートは、残留磁気６ｋＧ以上の１８Ｃｒ－８Ｎｉ系ステンレス磁石が複数個からなり、キャップはカップ状のホール部を複数個有するとともにそれぞれに永久磁石を装入して、複合磁石化による磁気吸引力の向上を図る。【選択図】図３
