摘要： A dental magnetic attachment which has a superior magnetic attractive force with a small nonmagnetic welded part and a flat welded surface to be polished. The dental magnetic attachment including a magnet, a yoke with a pit to hold the magnet, a sealing disk placed on the opening of the pit to cover the magnet and a nonmagnetic welded part between the yoke and the disk. The yoke and the disk are made from soft magnetic material. The nonmagnetic welded part, which joins the yoke and the disk, is formed by welding the yoke, the sealing disk, the sealing ring made from nonmagnetic austenitic stainless steel and a Ni coat between the sealing disk and the sealing ring together. Here, it is preferably that there remains a part of the nonmagnetic sealing ring. The welded surface of the dental magnetic attachment is polished to be flat.

摘要： A dental magnetic attachment having good cushioning properties against a compressing pressure which makes a denture sink appropriately on biting. The dental magnetic attachment embedded in the denture base for holding the denture in the oral cavity by a magnetic attractive force working with the magnetic assembly and a soft magnetic keeper embedded in the top of the root surface includes a magnetic assembly and a cap covering the top of the magnetic assembly. The magnetic assembly has a hollow in the center of its top. The cap with a button is placed on the magnetic assembly, inserting the button into the hollow to contact to its bottom. On biting, the button is compressed, to be deformed with a shorter thickness and at this time a sleeve formed as a body around the core slides down along the side of the magnetic assembly to reduce the thickness of the dental magnetic attachment. This sliding makes the denture sink uniformly and appropriately. The dental magnetic attachment has good cushioning properties and offers a good feeling to a patient when biting with the denture.
摘要翻译：牙科磁性附件具有抵抗压缩压力的良好缓冲性能，这使得义齿在咬合时适当地下沉。嵌入在义齿基座中的牙科磁性附件通过与磁性组件一起工作的磁性吸引力和嵌入根表面顶部的软磁保持器将义齿保持在口腔中，包括磁性组件和覆盖顶部的帽的磁性组件。磁性组件在其顶部的中心具有中空部分。带有按钮的盖子放置在磁性组件上，将按钮插入空腔中以接触其底部。在咬住时，按钮被压缩，以更短的厚度变形，此时，作为主体围绕芯部形成的套筒沿着磁性组件的侧面向下滑动以减小牙齿磁性附件的厚度。这种滑动使得义齿沉没均匀和适当。牙齿磁性附件具有良好的缓冲性能，并且在与义齿咬合时对患者提供良好的感觉。

摘要： The aim of the present invention is to offer a keeper for a dental magnetic attachment that is strong, has low manufacturing costs, and is not easily detached from the tooth root. The keeper proposed herein has a keeper body, which is shaped like a plate, and a root, which is attached to the bottom of the keeper body. The keeper body and the root are machined from a single piece of soft magnetic material in one piece. The root has a smaller diameter part that is linked to a larger diameter part whose external diameter is larger than an external diameter of the smaller diameter part. The smaller diameter part is linked to the bottom of the keeper. There are multiple circumferential grooves around the outer side of the larger diameter part.

摘要： A denture attachment including a magnet body, to be embedded in a denture base, comprises a pair of soft magnetic alloy end plates, a non-magnetic alloy spacer disposed between the end plates, and a cap covering the magnet body, the end plates and the spacer except on the side of a coping. The attachment causes a magnetic attractive force of the magnet body to act on the coping of a soft magnetic alloy embedded in a pulp cavity of a tooth deprived of the crown, whereby the denture base is stabilized on gingiva. The magnet body is disposed with its N and S poles facing the end plates, respectively.

摘要： A dental attachment is embedded in a denture base so as to attach to a keeper made of a soft magnetic material built in a tooth root by magnetic attractive force. The dental attachment comprises an attachment main body which has a magnetic body delivering magnetic attractive force and a cap which covers a head portion located on the opposite side of an attractive surface to attach the keeper of the attachment main body. The cap, made of a non-magnetic material, is installed in the attachment main body so as to be able to move between a contacting position (A) which contacts with the head portion and an extended position (B) which is far from the head portion for a certain distance.
