ARTIFICIAL TOOTH STABILIZING PERMANENT MAGNET STRUCTURE, ARTIFICIAL TOOTH STABILIZING KEEPER, AND ARTIFICIAL TOOTH STABILIZING MAGNETIC ATTACHMENT

摘要

An artificial tooth stabilizing permanent magnet structure utilizing magnetic attraction and an artificial tooth stabilizing keeper of the present invention are made of a magnetic material having a high saturation magnetic flux density and essentially consisting of 15.5-18.5 wt.% Cr and Fe substantially constituting the remaining, thereby reducing the magnet structure in size while providing an attachment with a great magnetic attraction. An artificial tooth stabilizing attachment is also provided. In addition, the artificial tooth stabilizing permanent magnetic structure and the artificial tooth supporting keeper further comprises a coating of Ti or a Ti compound to improve the corrosion resistance while providing a practically required level of magnetic attraction, in order to enhance the safety of the magnetic attachment.
