Detailed Specs & Benefits of KATANA™ Zirconia YML
KATANA™ Zirconia YML
High translucency and high strength are combined within a single disc, allowing the entire indication spectrum to be covered—from veneers to full-arch restorations. This minimizes the need for multiple zirconia disc inventories and streamlines workflows.
Features & Benefits
Fast Processing with 90-Minute Sintering
Innovative pressing and pre-sintering technology allows high-speed sintering of up to 3-unit bridges in just 90 minutes—perfect for remakes, rush cases, and same-day restorations, boosting productivity without sacrificing quality.
Seamless Esthetics
Proprietary multi-layered technology eliminates visible transition lines, delivering a natural gradient in color and translucency that closely mimics natural dentition.
Controlled Firing Deformation
Precision engineering and in-house material production ensure accurate shrinkage control, maintaining consistent fit and reducing the risk of remakes.
Marginal Stability & Enhanced Fit
Sharp margins and reduced chipping, even at minimal thickness, improve restoration fit and esthetics while supporting conservative tooth preparation.
Versatility of Application
Suitable for monolithic, cut-back, or framework designs, covering an extensive range of indications: laminate veneers, inlays/onlays, anterior/posterior crowns, long-span bridges, and frameworks.

FAQ
How do the mechanical properties of KATANA™ zirconia differ from each other?
The existing KATANA™ Zirconia multi-layer materials (KATANA™ Zirconia UTML/ STML/HTML) have a color gradation, while the base material of the respective type is the same for all layers and, besides, the strength and translucency are the same for all layers of the respective type. KATANA™ Zirconia YML is different in this regard. It is the latest KATANA™ multi-layer disc with a balanced combination of color/translucency and flexural strength gradation. Each series has the following mechanical properties and translucency levels: Please refer to the inserted charts.
What exactly does "All-In-One" mean?
"All-In-One" means all application range with one disc. KATANA™ Zirconia YML is characterized by a unique raw material combination of highly translucent zirconia with high strength, which are integrated together by an advanced manufacturing technology. As a “All-IN-ONE Solution" KATANA™ Zirconia YML offers exceptional design flexibility from long-span full-arch monolithic bridge restorations up to highly aesthetic anterior monolithic crown restorations.
What are the recommended and indicated application areas for KATANA™ Zirconia YML?
From complicated full-arch restorations to highly aesthetic demanding anterior single-unit restorations, an exceptional design flexibility is available. In each of these cases, you can choose a monolithic, cut-back or framework design with the appropriate fabrication process, depending on your specific needs.
Why is it possible to sinter KATANA™ Zirconia at such a high speed without compromising optical and mechanical properties?
KATANA™ Zirconia is characterized by the unique in-house production of zirconia raw materials: By using materials that Kuraray Noritake Dental has developed by themselves specifically for KATANA™ Zirconia, completely different from those of other competitors, it is possible to realize high-speed sintering without compromising the aesthetic and mechanical properties.
What shade selection is available for KATANA™ Zirconia YML and in which disc thicknesses and shapes are these available?
KATANA™ Zirconia YML is available in a shade selection of 14 shades, which are adapted to the VITA-classical A1-D4™ Shade Guide. Please refer to the following table overview for more information about shape and disc-thickness.
