The denture is embedded in plaster or the like, dewaxed and filled with ballast, etc., the denture body is extracted from the plaster, and the denture is polished to complete the denture. These operations are only so-called technician operations, and in reality, the preliminary steps include diagnosis, impression (mold-taking), model creation, occlusal recording (taking the upper and lower positional relationships), and confirmation of the alignment position. Ru. Prosthetic dentures created through such a large number of steps include factors that inhibit proper occlusal relationships during each step, and it is extremely difficult to reproduce the patient's unique occlusal state.

要していた。(Problem to be solved by the invention) It is extremely rare for dentures made as described above to completely match the actual occlusal condition. After the denture is placed in the patient's mouth, ceramic lapping abrasive grains are placed on the occlusal surface.
A method is adopted in which the patient's chewing action is used to wear down the occlusal surface, thereby adjusting the occlusal condition to be unique to the patient. However, since the abrasive grains are ceramic powder particles, they do not stay stably on the occlusal surface of the denture, making it impossible to achieve smooth and sufficient occlusal adjustment. Therefore, the actual situation is that the above abrasive grains are kneaded with pharmacopoeial glycerin and used in the form of a paste. However, even in this case, glycerin is dispersed in the oral cavity, and since the retention force of glycerin is small, the abrasive grains are also dispersed, resulting in variations in occlusal adjustment. For the patient, the patient has just put on a newly created denture that he or she is not used to, and such occlusal work feels uncomfortable. In addition, when you are not used to wearing dentures, you cannot smoothly control your tongue and buccal muscles, so loose glycerin and abrasive particles are more likely to disperse, and they may intervene between the dentures and the mucous membranes, damaging the mucous membranes. It also had the disadvantage of causing injury. Furthermore, the paste placed on the occlusal surface is expelled outside the occlusal surface by occlusal movements;
Since the discharged paste has no caking properties, it simply disperses and does not return to the occlusal surface. Therefore, the polishing efficiency of the abrasive grains is poor, and it takes a lot of time and effort to obtain an accurate occlusal surface.

分を添加することも自由である。The viscoelastic resin base material may be a natural or artificial material (for example, vinyl acetate, etc.) used in so-called chewing gum.
Gum base and other viscoelastic synthetic resins that are harmless to the human body are used. Further, as the abrasive grains, diamond powder, boron carbide, green carborundum, white arundum, vitrified, magnesia, zirconia and other ceramic lapping abrasive grains are preferably employed. These abrasive grains are contained in the viscoelastic resin base material.
It is desirable that the apparent crosstalk is 5 to 80% by volume, and 80
If it exceeds 0.5%, it tends to be excessively polished;
If it is less than %, a sufficient polishing effect cannot be obtained. The above abrasive grains are generally No. 800 (particle size 20 to 30 μm), No. 1500
No. (8 to 16 μm), No. 3000 (3 to 8 μm),
No. 5000 (0.5 to 3 μm), and in the present invention, these are respectively kneaded into the viscoelastic resin base material and used depending on the occlusal adjustment stage. Furthermore, in order to give a refreshing feeling and taste to the oral cavity, suitable fragrances and sugars can be added freely.

The prepared denture is placed in the patient's oral cavity, and the adjusting material mixed with No. 800 abrasive powder is placed on the occlusal surface of the denture, and the denture is brought into occlusion under the guidance of a doctor. Once it has been confirmed that the scratches and burrs caused by the bar grinding with the handpiece are removed and the occlusal contact is appropriate, the same occlusion is performed using an adjustment material mixed with No. 1500 and No. 3000 abrasives, and as a finishing touch, the occlusion is made using No. 5000. Occlusal adjustment is completed using the abrasive kneading adjustment material. When a patient chews these adjustment materials, the surface of the denture is ground or polished by the action of the abrasive grains contained therein, and by stacking these materials, an occlusal condition unique to the patient can be accurately obtained. In addition, since the base material is made of viscoelastic resin, its holding power prevents the contained abrasive grains from becoming loose, and it also has elastic restoring power, so it maintains its lumpy shape and can be easily adjusted by the movements of the tongue and buccal muscles. This can be returned to the occlusal surface, so that unworn abrasive grains are always placed on the occlusal surface, ensuring efficient occlusion. Furthermore, due to its viscoelasticity, it is possible to always apply the same pressure and move it under pressure.
It is possible to grind or polish any complex three-dimensional curved surface. A series of occlusal adjustments as described above can be made in just a few minutes, allowing extremely rapid denture prosthesis.

る本発明は実用価値極めて大である。(Effects of the Invention) As described above, the occlusal adjustment material of the present invention is made by kneading abrasive grains into a viscoelastic resin base material, so if it is interposed on the occlusal surface and chewed after the denture is attached, The denture is ground or polished by the action of the abrasive grains accompanying the occlusion, and the patient's unique occlusal condition is accurately reproduced. Moreover, since the base material is made of viscoelastic resin, the abrasive grains do not come loose and are always returned to the occlusal surface, making the most of the abrasive grain functions and ensuring efficient occlusal adjustment. Even original curved surfaces are thoroughly ground or polished. The present invention, which has such remarkable effects, has extremely great practical value.
