<p>The anchoring (9) intended to be inserted in teeth roots is galvanically insulated outwardly at least on its portion inserted in the root (1) to prevent voltages occurring by galvanic contact in the electrolytic medium. Thus, currents between the anchoring and surrounding tissues are suppressed so as to prevent any tissue distruction and any formation of toxic agents. Hence, when selecting materials for the artificial tooth, it is less important to take into account the presence of other contact potential differences. It is therefore possible to set an artificial tooth (21) on an anchoring (9), which are both made integral by means of two permanent magnets (19, 23).</p> |
