<p>PURPOSE:To obtain a keeper of a dental magnetic attachment capable of obtaining a normal image without receiving the effect of a magnetic field by making a keeper main body composed of a magnetic material and a keeper support composed of a non-magnetic material freely detachable and fixing the keeper support to the upper end surface of the root surface member embedded in a dental root. CONSTITUTION:The keeper 10 of a dental magnetic attachment consists of a keeper main body 10a formed into a circular shape from corrosion-resistant magnetic stainless steel such as SUS447J1 and a keeper support 10b formed into a circular shape from non-magnetic stainless steel. Since a female screw 12 is formed to the keeper support 10b, the keeper main body 10a and the keeper support 10b are made freely detachable. The keeper is integrally embedded by internal chill in such a state that the keeper main body 10a and the keeper support 10b are connected to the end part of the root surface member 3 embedded in a dental root with a corrosion-resistant non-magnetic material such as gold alloy through male and female screws 11, 12.</p> |
