The present invention relates to a denture attachment using a magnetic material capable of fixing dentures to gums to be detachably attached by a magnetic force, preventing a separation phenomenon of dentures caused by decrease in the magnetic force as a magnet is easily replaced, and not applying an excessive force to an implant when dentures are vertically moved by having elastic members individually exerting elasticity on upper and lower sides of the magnet. According to an embodiment of the present invention, the denture attachment using a magnetic material comprises: an upper case inserted inside dentures, and in which an inside is hollow, a lower part is opened, and a first screw thread is formed in an inner circumferential surface; a lower case which is screw-combined inside the upper case, so a lower end is exposed to an outside of the dentures and an inside is hollow, and in which upper and lower parts are opened and a second screw thread combined with the first screw thread is formed in an outer circumferential surface; elastic members individually located on upper and lower sides of the lower case; a magnetic material located between the upper and lower elastic members, and elastically lifted and lowered by the elastic members; an implant placed in an alveolar bone; and a keeper member screw-combined on the implant, made of a material generating an attractive force with the magnetic material, and fixing the dentures on which the magnetic material is prepared to be detachably attached to the alveolar bone by a magnetic force. |
