The " 3 " in " Noritake Super Porcelain EX-3 " refers to the 3 characteristics of the Noritake Porcelain series. Noritake manufactures the highest quality dental porcelain available on the market today.

1.Outstanding Resistance to Fractures:
Fractures frequently seen on dental porcelains are mainly caused by the incompatibility of the thermal expansion coefficient between the alloy and the porcelain. And the thermal expansion of the porcelain varies drastically subject to the baking repetition, cooling rate, post soldering and so on.
However, Noritake Super Porcelain EX-3 succeeds in the stabilization of the thermal expansion and therefore minimizes the risk of fractures even with the fabrication of long span bridges using precious, non-precious, or semi-precious alloys.




The risk of fractures as shown above is minimized with the application of Super Porcelain EX-3.

2.Prevention of Greening Induced by Silver.
A. Minimal greenness with fusion to semi-precious silver alloys.
B. Greenness of Super Porcelain EX-3 is minimized even baked in a silver-contaminated furnace.
C. Greenness caused by post soldering is minimized even with Gold-Palladium-Silver alloys or Gold-Platinum alloys.
The silver-free semi-precious alloys usually cause a number of problems associated with post soldering strength, however, with EX-3, the semi-precious silver alloy is applicable wlthout the worry of greenness.

Furthermore, not only the base(build-up) porcelains, but also the margin porcelain, the stain and the glazing powder of EX-3, are featured with the satisfactory dentition simulation with minimal risk of greenness.

3.Ideal Fluorescence
Noritake Super Porcelain EX-3 successfully simulates the bluish white fluorescence of the natural dentition.

The fluorescence even similar to the natural dentition may turn green under the influence of silver. This problem has now been effectively solved by the application of EX-3 porcelain.
