ことが多い。2. Description of the Related Art Conventionally, a keeper 10, which is an element of a denture attachment utilizing magnetic attraction, is composed of a thin plate-shaped keeper body 101 and a rod-shaped maintenance rod 102, and is usually attached to a root plate 103 by casting. It is fixed.
FIG. 8 is a diagram showing the structure of the root plate 103. When the keeper is fixed to the root plate 103, the maintenance rod 102 for fixing in the mold is provided so that it can be securely fixed at a predetermined position in the mold. It is installed. Further, when performing the fitting work for accurately positioning the keeper 10 on the root plate 103, the sustain rod 102 is generally bent and used in many cases.

For this reason, as shown in FIG.
The joint portion 105 between 01 and the sustain rod 102 is not entirely joined, and the joint area is small. Further, the retaining rod 102 has a recessed portion at which it joins the keeper body 101, and becomes thinner.

る。The present invention is an element constituting a denture attachment, which is attracted to a magnetic body held in a denture base and fixed to a root plate embedded in a tooth root portion, In the method for manufacturing a keeper for a denture attachment, which comprises a plate-shaped keeper main body whose main surface is an attracting surface to be attracted to a magnetic body, and a maintenance rod whose one end is integrally fixed to the side surface of the keeper main body, The rod is a method for manufacturing a keeper for a denture attachment, characterized in that the entire joint surface with the keeper body is melted and joined.

とが好ましい。What is most noticeable in the present invention is that, when the retaining rod is joined to the side surface of the keeper body, welding is simultaneously performed from two directions to join the side surface of the keeper body. That is, in the present invention, the conventional method of irradiating each side with one point and joining the maintenance rod to the side surface of the keeper is changed to simultaneous irradiation from two directions to melt the entire joining surface of the maintenance rod to keep the keeper. It is joined to the side of the body. Further, when the sustaining rod is pressed against the side surface of the keeper body at the time of joining, the melted portion of the sustaining rod becomes large and the joining strength with the keeper body is further improved. For example, 0.3 for a sustain rod with a diameter of 0.5 mm
A pressing force of ~ 1.5 kgf is preferred. On the other hand, if the pressing force against the sustaining rod is too low, the joint surface of the sustaining rod will not be sufficiently melted, and it will be difficult to join to the side surface of the keeper body. Conversely, if the force is too large, the sustaining rod may bend. Therefore, it is preferable that the pressing force is 0.7 to 1.1 kgf.

In the method for manufacturing the denture attachment of the present invention, the entire joining surface of the retaining rod is melted by welding and joined to the side surface of the keeper body. Therefore, the joining area of the sustaining bar is increased, the joining strength between the keeper body and the sustaining bar is improved, and the keeper does not easily break even when bent.

In laser welding or electron beam welding, it is preferable to irradiate and join the sustaining bar simultaneously while pressing it against the side surface of the keeper body from two opposite directions. Further, also in the electric resistance welding, it is preferable that the maintenance rod is joined while being pressed against the side surface of the keeper body.

ても、同じような結果が得られた。As shown in the measurement results of Table 1, the comparative sample 1 and the comparative sample 2 were irradiated with a laser beam or an electron beam, one point on each side, when the sustain bar was joined to the side surface of the keeper body. Since the maintenance rod was joined at the welding spot, it bent when bent up and down a few times. Further, the comparative sample 3 and the comparative sample 4 are simultaneously irradiated by laser welding from two directions and joined, but the pressing force when joining the maintenance rod to the side surface of the keeper body is 0. Since it was as low as 1 kgf, the joint surface of the sustain rod was not sufficiently melted and the joint strength was low. Further, in Comparative Sample 4, the pressing force was 1.7 kgf, which was too large, so that the sustaining rod was bent. On the other hand, in the case of the keeper manufactured by the method of the present invention, Sample 1 and Sample 2, by simultaneously irradiating from two directions with a laser or an electron beam, the sustain bar is pressed toward the side surface of the keeper body. Since the entire joining surface of No. 1 was melted and joined to the side surface of the keeper body, the sustaining bar did not break even after bending 4 times or more. Similar results were also obtained for Sample 3 using electric resistance welding.
