Summary:PROBLEM TO BE SOLVED: To enable to manufacture a relatively thin artificial dental root with precision, by making a material to be worked to be a screw type dental root autorotate to approach a discharge electrode of an electric discharging machine to a screw forming part of the material and threading the threads moving the discharge electrode and the material to be worked relatively. SOLUTION: This dental root 4 comprises a head 5 to be held on a rotation indexing device 8 by a chuck 9, a neck part 6, and a screw forming part 2. Innumerable discharge marks with the size of about 0.01-0.03 are formed on the screw forming part 2 to which threads 3 are threaded to make the surface satin-finished. When such a dental root as that is manufactured, a material 1 to be worked is mounted on the rotation indexing device 8 to approach a wire electrode 10 to a screw forming part 2 to thread threads 3. Since such discharge working as this cuts a material to be worked without applying pressure, even a thin artificial dental root generates no strain to thread the threads 3 precisely.
