Description

[Detailed description of the invention] If the remaining prosthetic tooth is used as an inner crown, it will easily separate from the denture that matches the outer crown unless carefully processed. In this case, the two are bonded together with cement, but the alveolar ridge temporarily shrinks and the dental socket is damaged, which not only shortens the service life of the dental socket but also increases the cost of the denture. be.

In view of the above points, it is an object of the present invention to provide dentures hygienically and at low cost.

The details of the present invention will be explained below with reference to FIG. 1. A magnet 2 to be embedded in a tooth base 1 of a residual tooth portion as an internal crown;
It is characterized in that it consists of a denture 3 as an outer crown that includes a magnetic alloy that is adapted to be attracted to the magnet 2 and is detachably fitted to the tooth base 1.

In the illustrated embodiment, a plurality of chevron-shaped tooth stands 1 are formed by prosthetizing the remaining teeth to an appropriate size with non-magnetic metal, and magnets 2 are embedded inside the teeth.

On the other hand, a recess 3' is formed on the lower surface of the denture 3 containing a magnetic alloy. Next, to explain the bridge-type double gold-crowned denture with reference to Fig. 2, a magnet 2 is embedded in the tooth base 1, and a recess 3' is formed in the bridge gold-crown-type denture 3 containing a magnetic alloy to align with the tooth base 1. has been done.

Incidentally, an interproximal denture 4 is fixed to the denture 3, which closes the gap between the tooth bases 1 and improves the appearance. When using the present invention as described above, the denture is attracted to the magnet embedded in the tooth base, and the denture is removably iron-bonded to the tooth base, so it is different from the conventional double gold crown denture. In comparison, the precision of the machining of the tooth base 1 and the denture 3 can be reduced.

Therefore, according to the present invention, the denture work by the doctor can be done simply and quickly, and the cost of dentures can be reduced. In particular, bridge gold crown devices require accurate spacing between the teeth, but this invention alleviates this, and when the denture is fixed with cement like a secondary denture, the intermediate denture part (interdental denture) is used. Because a hygienic space is created between the teeth and the alveolar region, the head ridge becomes thinner and the lifespan of the dentures is shortened. In the present invention, since the bridge gold crown denture can be removed and cleaned at any time, the above-mentioned gap is unnecessary, and stripes on the alveolar ridge corresponding to the intermediate denture area (interproximal denture) are prevented, which is hygienic and the denture can be used for a long time. It is a useful invention. Furthermore, the present invention does not involve embedding a magnetic material in the gingiva as in the conventionally known technique of Japanese Patent Publication No. 50-15514, but instead embeds a magnet in the remaining tooth area, so it is not necessary to embed a magnet in the remaining tooth. There is no need for surgery; simply bonding a magnet to the tooth with dental cement is sufficient. In addition, with the above technology, the magnetic material in the gums will eventually be exposed outside the living body due to the removal of foreign substances. In addition, magnetic materials and dentures constantly press pressure on the gums, causing blood circulation disorders, but the present invention has the excellent effect of not impairing the health of the gums at all.
