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 magnetic device includes a cylindrical portion and a flange portion. The cylindrical portion is mounted with a cylindrical shaped flexible sleeve. The sleeve is axially longer than the cylindrical portion and includes an outer peripheral concavo-convex portion. When one end of the sleeve is abutted on a flange portion, the other end of the sleeve is projected above an attractive surface to form a keeper housing recess. The sleeve is relatively moved in an axial direction of the magnetic device to be inserted into and removed from a top end of the cylindrical portion. The magnetic device is used under condition the sleeve is fitted, an outer side surface of the magnetic device including the outer peripheral concavo-convex portion of the sleeve and the flange portion abutted on the one end of the sleeve is embedded in a denture base, and the keeper housing recess is exposed.

摘要： A dental attachment is disclosed which provides an improved connection force and fitting between an implant and a keeper. A keeper has a main body with a attracted face, a screw part that is located at the back face, a conical tapered shaft, and a projecting ring part. The projecting ring part has an inclining inner face and an acute angle pointed end. An implant has a screw hole part, a conical tapered hole part which has about the same inclining angle of the tapered axle part, and an inclining end face. When the keeper and the implant are connected, the tapered shaft and the tapered hole part are fitted closely and at the same time, the inner face of the acute angle pointed end and the inclining end part are in contact and at least the acute angle pointed end of the projecting ring part is elastically transformed toward the diameter.

摘要： The present invention is a bar type dental attachment for implants that makes use of magnetic attractive force to secure a denture in place. This bar type dental attachment can rotate corresponding to the movement of the denture during occlusion. The present invention has excellent wear resistance and makes insertion and removal of the denture easy. The present invention has a bar type keeper with an arced attractive face with a constant radius of curvature, and a magnetic assembly that comprises a magnet, a pair of yoke plates sandwiching the magnet, and a seal material made of anticorrosive non-magnetic material that covers the magnet and is hermetically sealed. The attractive surface of the magnetic assembly is curved to fit the keeper.

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.

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.
