Zirconia is used as a radiographic agent for various　biological cases, such as in dental materials and　joint prosthesis.
Zirconia is a chemically stable substance so　change of color is unlikely to happen.

At the moment the cement comes into contact with water,　it is absorbed and becomes cement mud.　The bearing effect of the spherical silica particles improves　the product’s fluidity. This enables you to make an even　paste easily with a small amount of water in a short time.　Although we have increased the number of zirconia　particles to improve the X-ray contrast, since the particles　are the round shape, easy operation remains.

Since it sets quickly, the product achieves high compressive strength (about 90 MPa) from one day after application. The compressive strength reaches about 140 MPa after a week, matching the compressive strength of glass ionomer cement.

Since it can be mixed with a small amount of water, the product sets quickly so that initial setting is completed in 15 to 30 minutes. Also, it sets sufficiently without any need to replenish the moisture with a moistened cotton pellet after application. If the paste gets dry and difficult to handle, the viscosity of the paste can be adjusted by adding moisture.
