To quickly differentiate undifferentiated mesenchymal cell containing phosphoric acid-calcium ions, nutrition, oxygen, and the like, and assimilated with physicochemical stimuli into a specific alveolar bone and a trabecular bone by passing an electric current inside the biotissue between an implant part of a dental implant and the cortical bone of the jaw bone and exciting a hemopoietic operation.
The artificial specific alveolar bone 31 has a cylindrical shape having an opening part for wrapping the implant part of an inner dental root 32, has a plurality of through-holes for forming the specific alveolar bone and the trabecular bone on its surface, and is functioned as an electrode for inducing the differentiation of cells forming the specific alveolar bone and the trabecular bone by the electric current.
