    • PROBLEM TO BE SOLVED: To provide a denture attachment, wherein a recess in a cup-shaped yoke is sealed by weld with excellent quality, magnetic adsorption ability is high, and corrosion resistance is good.
      SOLUTION: The attachment includes a permanent magnet, the cup-shaped yoke made of a corrosion-resistant soft magnetic material with the recess housing the permanent magnet, and a seal plate inserted into an opening of the recess in the yoke. The seal plate comprises a platy yoke made of the corrosion-resistant soft magnetic material and a seal ring made of the corrosion-resistant soft magnetic material installed on a periphery of the platy yoke. The seal plate is connected to the yoke by a plurality of spot welding areas which fix at least a butting part of the yoke and the seal ring, and by at least one all around welding area formed so as to cover a butting part of the yoke and the seal ring and a butting part of the seal ring and the platy yoke, thereby the permanent magnet is sealed.

    • PROBLEM TO BE SOLVED: To provide a keeper tray corresponding to the removable keeper for easily casting a root cap by a lost wax method, wherein the root cap is capable of attaching a conventional shaped keeper without losing magnetic attractive force, does not damage an edge of a space in which the keeper is inserted and adherently fixed when the keeper is removed at a time of MRI diagnosis, and is capable of detaching the keeper and attaching the keeper after the diagnosis.SOLUTION: The keeper tray corresponding to the removable keeper is used at a time of casting a root cap for a dental magnetic attachment having a space S, in which the keeper is inserted and adherently fixed, by a lost wax method. The keeper tray corresponding to the removable keeper is made of a synthetic resin or a metal and has the formed space S thereon. The keeper tray corresponding to the removable keeper has a shape in which an opening 2 is formed on the bottom surface 1 by cutting out from an outer peripheral portion 1a of the bottom surface 1 to a center portion and opens to a space S.
    • 要解决的问题:提供一种与可拆卸式保持器相对应的保持器托盘,用于通过失蜡方法容易地铸造根盖,其中根盖能够连接常规成形的保持器而不丧失磁吸力,不 在MRI诊断时,当门禁器被拆除时,会损坏保持器插入的空间的边缘并粘贴固定,并且能够在诊断之后分离保持器并附接保持器。 解决方案:在通过失蜡方法将具有空间S(其中保持器插入和粘附固定)的牙科磁性附件铸造根帽时,使用与可移除的保持器相对应的保持器托盘。 对应于可移除的保持器的保持器托盘由合成树脂或金属制成,并且在其上形成有形成的空间S. 对应于可移除的保持器的保持器托盘具有通过从底面1的外周部分1a切除到中心部分而在底面1上形成开口2并打开到空间S的形状。
