In this case, since the impression material comes into direct contact with the patient's oral cavity, it is contaminated with bacteria and viruses carried by the patient, but because it needs to maintain its shape, it cannot be cleaned under extreme conditions. , handled in contaminated conditions. Therefore, dental technicians who handle impression materials are constantly exposed to the risk of infection. Especially in recent years, hepatitis B and AIDS (
The possibility of infection with AlDS) has become a problem.

ハイドロコロイド印象材の安全性を損なう恐れがある。[0003] Therefore, a method has been considered to prevent infection by incorporating an antibacterial agent into microcapsules and incorporating it into alginate impression material (Japanese Patent Application Laid-open No. 100110/1999), but this method requires the step of creating microcapsules. Not only does this make the manufacturing method complicated, but since it contains a water-soluble antibacterial agent, there is a possibility that it may elute into the oral cavity, which may impair the safety of dental hydrocolloid impression materials.

成物といい得る。[Operation] The present invention aims to fully exhibit its effects by coexisting a slightly water-soluble antibacterial agent with a hydroxy compound and a surfactant. Furthermore, since it is sparingly soluble in water, moisture absorption does not occur and deterioration of the impression material and deterioration of physical properties due to moisture absorption can be prevented. Furthermore, since there is no risk of elution into the oral cavity when an impression is taken, it can be said to be a safe impression material composition.

ましい。The hydroxy compound is not particularly limited, and examples include polyethylene glycol, glycerin,
Hydroxypropyl cellulose and the like can be used as appropriate. By adding a hydroxy compound, it is possible to improve the dispersibility of the slightly water-soluble antibacterial agent into the hydrocolloid impression material, and it is possible to uniformly coat the hydrocolloid impression material. Furthermore, since it is possible to prevent the powder of the alginate impression material or agar impression material from scattering when the impression material is used, very little dust is generated. In order to achieve the above objective, it is preferable to add 0.5% by weight or more.

By adding a surfactant, it is possible to further improve the wettability for improving the dispersibility of the slightly water-soluble antibacterial agent and hydroxy compound into the hydrocolloid impression material. The amount added is 0.005 to achieve the above purpose.
It is preferable to add more than 5.0% by weight, but if too much is added, the effect will be saturated and even hindered, so it is preferably 5.0% by weight or less.

An antibacterial hydrocolloid impression material was prepared by uniformly coating the antibacterial agent.

On the other hand, Comparative Example 6 does not show antibacterial properties because no antibacterial agent or the like is added, Comparative Example 7 does not contain a hydroxy compound or surfactant, and Comparative Examples 9 and 10 do not contain a surfactant or hydroxy compound. was not added, the surface of each impression material could not be coated, and sufficient antibacterial properties could not be obtained. It also had a large surface roughness. In Comparative Example 8, water-soluble benzalkonium chloride was added as an antibacterial agent, and the antibacterial properties were excellent, but the surface was rough due to its hygroscopicity.

Therefore, it has become possible to provide a dental hydrocolloid impression material composition that does not absorb moisture, has a smooth surface texture, and has sufficient antibacterial properties. Furthermore, since the antibacterial agent does not elute into the oral cavity, it is also excellent in safety. Furthermore, the hydrocolloid impression material composition of the present invention generates very little dust and is very easy to handle.
