A magnetic field generator 3 is attachable to an implant body 2 formed from a non-magnetic material to be inserted in jawbone 61. The magnetic field generator 3 includes a magnet body 30 that generates magnetism. The magnetic field generator 3 is mountable to and removable from the implant body 2. The magnetic field generator 3 in a state of being mounted to the implant body 2 forms a magnetic field around the implant body 2.磁場產生裝置(3),係被配置在人工植體本體(2),該人工植體本體(2)是由以埋設在顎骨(61)內之方式構成的非磁性體所成。磁場產生裝置(3),具備可產生磁性的磁石體(30)。且,磁場產生裝置(3),構成為:能夠與人工植體本體(2)進行裝卸,並且在安裝狀態下,可在人工植體本體(2)的周圍形成磁場。1‧‧‧人工植體裝置2‧‧‧人工植體本體3‧‧‧磁場產生裝置6‧‧‧顎堤26‧‧‧凹部261‧‧‧母螺紋部30‧‧‧磁石體31‧‧‧插入部333‧‧‧公螺紋部35‧‧‧頭部50‧‧‧人工植體保護用義齒51‧‧‧義齒齒床511‧‧‧頂部512‧‧‧側壁部513‧‧‧保護凹部53‧‧‧人工齒61‧‧‧顎骨62‧‧‧齒肉
