According to the present invention, in the process of forming a model tooth frame by molding a plate-shaped base member made of plaster or the like on the bottom of a model tooth modeled after a patient's tooth, the shape of the base member is not molded. At the same time, a metal member, which is a magnetic body, can be easily inserted in the state where the upper part is exposed so that the model tooth frame can be easily transported or stored. It is about.

Healthy teeth are so important in human life that there is a saying that one of human error is one.

Because teeth are convenient for swallowing foods and swallowing, the foods can be digested and absorbed smoothly in the stomach or intestines, and they can communicate with accurate pronunciation. Because it plays a very important role.

Tooth, which plays such an important role, is partly damaged by frequent contact with food, even though it is the most rigid part of the body part of the human body, and may be partially damaged by the impact of hard food, etc. In severe cases, all or part of the tooth may be lost due to an accident.

Tooth loss or damage as described above is directly affected by food intake and conversation, as well as affect other healthy, non-damaged teeth, it is desirable to be treated immediately if there is something wrong with the teeth, teeth Looking at how to treat as follows.

Prior to description, in order to avoid confusion in terminology, the following definitions are made.

That is, the abnormal teeth are completely replaced with artificial teeth, or covered or covered with metal, for example, gold, amalgam, platinum, etc. on the damaged part of the teeth, bar as described above Artificial teeth, metals, etc. to treat all will be referred to as 'dentures'.

In order to treat a lost or damaged tooth, first, the dentist completely removes the residue of the lost tooth or grinds the rotted or broken part.

Then, the patient's teeth are precisely seen using an agar mixture or the like, and powdered stone or pumice plaster is poured into the negative bone and then hardened to produce a model tooth that is identical to the patient's tooth shape. do.

When the model tooth is manufactured as described above, as shown in FIG. 1, as many pins 12 as necessary are coupled to the bottom surface of the model tooth 11.

And, as shown in Figure 2, made of a soft material such as silicon and having a upwardly open-type inner space, the pin 12 is coupled to the model tooth before the plaster is cured after pouring the plaster dough By placing the model tooth 11 on the upper surface of the gypsum dough to be embedded, as shown in Figure 3, the model tooth frame 32 is coupled to the upper surface of the base member 31 made of gypsum teeth (32) The production of is complete.

When the model tooth frame 32 is completed as described above, by cutting only the part of the model tooth 11 into a plurality of parts, as shown in FIG. 4, the partial model tooth 11A that needs treatment is model tooth frame ( 32 can be separated and combined.
