The present invention relates to a denture structure that induces easy detachment and seesaw action of an implant and a denture, and more particularly, by forming a concave hemispherical magnet body coupling structure of an implant, a hemispherical keeper and a concave hemispherical magnet. When the force is applied at any position in the denture detachment process through the sieve, natural detachment or attachment is possible, and the force of the implant is transmitted perpendicular to the axis of the implant by inducing the seesaw action when chewing or jaw movement. It is an object of the present invention to provide a denture structure for a hemispherical magnet-coupled implant having a seesaw motion structure for reducing the impact on the alveolar bone by switching in a parallel direction.
