Katana™ aesthetic zirconia is manufactured by one of the top porcelain companies in the world, Noritake. What is amazing about this aesthetic zirconia by Katana™ is the highly aesthetic results it can produce. The Katana™ zirconia disc is multi-layered which helps achieve a natural tooth appearance.
Katana™ zirconia has incredible strength (1200mpa), and still has a translucency like no other, getting impeccable results and has an advantage as a full contour zirconia crown versus a porcelain fused restoration. Katana™ contains an enamel layer, a first transition layer, a second transition layer, and finally a body layer. This leaves no issues while adjusting the crown, whereas a typical zirconia crown, that are dipped and stained, the shade could easily be removed while adjusting with a bur.
Katana Advantages
Strength: Zirconia crowns will outlast all other types of crown (this is the same material used in hip and knee replacement procedures).
Appearance: Crowns made with Katana Zirconia ML also happen to offer translucency solutions comparable to any other alternative on the market.
Minimal Invasiveness: Less preparation and impact to site means more of the original tooth is preserved.
