PURPOSE:Soft magnetic alloy for dental surgery, obtained by alloying Co, Ag, Pt at a specific ratio, using combined with rare earth Co base permanent magnet having a high magnetic energy. COMPOSITION:Alloy, composed of Co;30-65%, Ag;5-40%, Pt;30-65% and contained one or more than two kends of Mn, Zn, Sn, Al, Si, Mg as deoxidizer for obtaining casting alloy having no blow hole at not more than 5%. USE:The soft magnetic alloy 3 having the above mentioned composition, is filled in the root part of the tooth 2 remained in the flesh part 1. The rare earth Co base magnet 5 having a high magnetic energy, is put in the crown part of the tooth 4 so as to face the one hand magnetic pole against the alloy 3 and both are fixed by the magnetic sucking force. Thus, the above method is able to use for filling and reform of dental surgery effectively. |
