Abstract
A denture attachment including a magnet body, to be embedded in a denture base, comprises a pair of soft magnetic alloy end plates, a non-magnetic alloy spacer disposed between the end plates, and a cap covering the magnet body, the end plates and the spacer except on the side of a coping. The attachment causes a magnetic attractive force of the magnet body to act on the coping of a soft magnetic alloy embedded in a pulp cavity of a tooth deprived of the crown, whereby the denture base is stabilized on gingiva. The magnet body is disposed with its N and S poles facing the end plates, respectively.
