<p>PURPOSE:To remarkably stabilize and enhance the hold of an artificial tooth by placing a denture-base which is embedded therein with a magnet pairing with a magnet to be implanted or a ferromagnetic material, in position, in order to stabilize and hold the artificial tooth set on the denture-base. CONSTITUTION:There are provided an alveolar bone 1, a gum 6 including a mucous membrane periosteum 6, an embedding groove 7 for defining a recess in which a ceramic coated magnet 11 is embedded, a ceramic 12, a magnet or a ferromagnetic material 13 embedded in an artificial tooth 14 so as to pair with the ceramic coated magnet 11, and a ceramic group born make-up material 13 for securing the ceramic coated magnet 11 in the embedding groove 7. The ceramic 13 is excellent in in-vivo stability, organic affinity, mechanical strength and adhesion, and it is in particular excellent in mechanical strength so that it may be used for a bone make-up material, in addition to coating for the magnet 13. A samarium-cobalt (Sm-Co) group magnet, a neodium-iron- boron (Nd-Fe-B) group magnet or the like, which may be a forged article, a hot-rolled article, a sintered compact, a plastic composite or the like, may be used as the magnet 13.</p> |
