The super-translucent multi-layered zirconia – inspired by teeth

Restorations made of KATANA Zirconia STML allow the light to shine through in a tooth-like manner in the incisal area. In the cervical area the translucency is gradually reduced. The light transmission of KATANA Zirconia STML in the „Enamel Layer“ is comparable to IPS e.max* CAD LT. So that aesthetic full-contour restorations are possible regardless of the shade of the die.

The integrated translucency and color gradient makes KATANA Zirconia STML a pioneer among zirconium oxide materials. Let yourself be inspired by the aesthetics of the next full-contour restoration.
