脂がおかされて悪臭を生じるという問題もあった。2. Description of the Related Art Model teeth for dentistry training are widely used in the course of training of dentists in order to practice caries treatment, but conventional model teeth for dentistry training are model teeth for teaching materials made of synthetic resin. Because it uses a tooth, the cutting feeling is completely different from natural teeth due to hardness, slippage, stickiness, etc., and a new dentist who has been practicing dental treatment with such a conventional model tooth for dental training actually When it comes to the treatment of, many of them have the experience of being frustrated by encountering this difference in cutting feeling. In addition, the conventional model tooth for dental education made of synthetic resin has a problem that the synthetic resin is put on by the cutting heat generated at the time of cutting to generate a bad odor.

Alternatively, it is preferably semitransparent or amber. Further, the material of the ceramic is not particularly limited, but the hardness is set to a Brinell hardness of 50 to 200 ,
Further, materials for tooth model 4 of the ceramic shall had us to increase the toughness of the unsaturated polyester resin and other synthetic resin countless pores of the model tooth body made of porous ceramic is impregnated cured in a vacuum That is the present invention

ましい。The reason why the ceramic model tooth 4 for teaching materials is limited to one having a Brinell hardness of 50 to 200 is that if the Brinell hardness is less than 50, the ceramic is too soft to obtain a cutting feeling like a natural tooth. , Brinell hardness 2
If it exceeds 00, it is too hard to obtain a cutting feeling like natural teeth, and it is easily cracked and chipping occurs.
In addition , the model tooth 4 for teaching materials is assumed to be one in which the countless pores of the model tooth body made of porous ceramic are impregnated and cured with unsaturated polyester resin or other synthetic resin in a vacuum state.
It is especially preferable that the surface of the tooth is closer to that of natural teeth, and the toughness is imparted to the surface to prevent cracking, and there is no damage during storage or transportation.

In the range of 180 to 180, the overall evaluation was satisfactory in all cases, so the optimum range of hardness is 80 Brinell hardness.
~ 180. However, depending on the chip, a Brinell hardness in the range of 50 to 200 is sufficient.

た。(Experimental Example) Next, one of preferable experimental examples will be described. A foot for fitting to the base by a cast molding method or a press molding method by mixing a base soil composed of 20% feldspar, 20% clay, 30% clay, 5% dolomite, 5% calcium carbonate, and 20% calcium phosphate in weight percent. A large number of molar bases, premolar bases, canine bases, incisor bases, etc. in which parts are hung down are formed, dried and then fired in an oxidizing atmosphere of 1250 to 1400 degrees Celsius,
This was cooled to obtain a model tooth body made of porous ceramics. The model tooth body made of this porous ceramic was impregnated with an unsaturated polyester resin in a vacuum to cure the model tooth body to obtain a model tooth 4 for teaching material, and its hardness was measured to find that the Brinell hardness was 162. A large number of the model tooth 4 for teaching materials thus obtained is fitted into the model tooth insertion holes 3 arranged in a large number in the base 1 made of hard synthetic resin mounted on the metal frame 2. The model tooth 4 for each teaching material was fixed by a set screw 5 screwed from the back surface of the base 1. Cutting the dental training model tooth obtained in this way with a cutting tool equipped with the most representative diamond tip on the market, it is possible to perform comfortable cutting with a cutting feeling almost the same as natural teeth, During this time there was no chipping. Further, when cutting the model tooth for dental training in which the conventional model tooth for teaching materials is made of synthetic resin, there is no generation of a bad odor caused by the synthetic resin being exposed to cutting heat.

業界の発展に寄与するところ極めて大きいものがある。As is apparent from the above description, the present invention is based on a porous ceramic having a Brinell hardness of 50 to 200.
The model tooth made of ceramics is impregnated and hardened with synthetic resin. <br /> By inserting the model tooth for teaching materials made of ceramics,
The hardness, slippage, and stickiness of the model tooth for teaching materials are similar to those of natural teeth, and it is possible to practice dental caries treatment with the same cutting feeling as natural teeth, and the appearance is also close to that of natural teeth, so excellent teaching effects can be expected. Moreover, when it is desired to mark a cutting point on the model tooth for teaching material as necessary, since it is made of ceramics, it is possible to make a precise mark with a commercially available marker. Furthermore, the model tooth for teaching materials is made by impregnating and hardening synthetic resin in the model tooth body made of porous ceramics in a vacuum, so that the gloss and the like become closer to those of natural teeth, and toughness is imparted, making it difficult to crack. , Will be extremely commercial value. Therefore, the present invention solves the problems of the conventional model tooth for dental training, and has an advantage that it can be provided at low cost because it is easy to mass-produce, and contributes greatly to the development of the industry.
