The keeper 2 made of the soft magnetic material is mounted in a mounting hole formed on the upper end of a root surface plate 3, and the magnetic structural body and the keeper are arranged to face each other, thus the denture base is fixed on the root surface plate 3 with a magnetic attracting force between the magnetic structural body and the keeper. At least one groove in the peripheral direction is formed on the magnetic structural body and/or the outer periphery of the keeper, and at least one groove in the peripheral direction is formed on the mounting hole for magnetic structural body and/or the inner periphery of the mounting hole for the root surface plate.
