KATANA Zirconia YML 14MM

KATANA™ Zirconia YML is a new definition of zirconia in dentistry. Characterized by a unique raw material combination of highly translucent zirconia with high strength, this innovative material will truly empower your dental lab.

BENEFITS

• FROM CONTROL TO CONSISTENCY. FROM CONSISTENCY TO CONFIDENCE.
• Eliminates visible transition lines, emphasizing natural color and translucency KATANA™ Zirconia YML matches three raw materials with different yttria contents combining a well-balanced color/translucency and flexural strength gradation. The seamless multi-layered technology eliminates visible transition lines, emphasizing natural color and translucency, ensuring a simplified, time-saving procedure. The fitting accuracy of restorations after the final sintering process reduces remanufacturing risks. No waste of time and materials. KATANA™ Zirconia YML has well-balanced combination of color/translucency and flexural strength gradation. Thanks to Kuraray Noritake Dental Inc.´s (Kuraray Noritake Dental) proprietary multi-layer technology, this latest development has been realized by matching three raw materials with different yttria contents. These layers are perfectly harmonized to each other due to the fact that all fundamental production steps, including purification, refining of the zirconia raw material and the addition of essential components such as yttria, are all processed in-house by Kuraray Noritake Dental. Combined with a proprietary zirconia pressing technique as well as our refined pre-sintering process, the new KATANA™ Zirconia YML fits harmoniously in the KATANA™ family. As a "All-In-One Solution" KATANA™ Zirconia YML offers exceptional design flexibility from long-span full-arch monolithic bridge restorations to highly aesthetic anterior monolithic crown restorations.

LAYERS

• Enamel Layer: To provide high translucency that harmonizes with the anterior teeth.
• Body Layer 1: To provide seamless color and translucency towards the Enamel Layer.
• Body Layer 2, 3: To provide deep and vivid color while reducing whitening. Kuraray Noritake Dental distinguishes itself by its unique in-house production of zirconia raw materials. Many years of expertise in manufacturing the company's own powder have brought the material quality of KATANA™ to completely new dimensions, not only by controlling the degree of purity and particle sizes, but also by creating an optimal balance of binders, color pigments, stabilizers and other ingredients. In this way Kuraray Noritake Dental guarantees its customers a material they can always rely on. Most zirconia begins with standardized powder bought off the shelf. KATANA begins earlier — at the raw material, inside Kuraray Noritake's own production in Japan. Own powder technology, a unique pressing principle and a unique pre-sintering principle mean we influence the material from the very first step — so we can influence the final result. Backed by the esthetic heritage of Noritake ceramics. Quality can't be added at the end — it has to be built in from the start. Because KATANA owns the powder, the pressing and the pre-sintering, it removes the variability rivals inherit the moment they buy standardized powder. The payoff is downstream: a denser, more homogeneous blank, cleaner milling and more predictable sintering — a result you can repeat, disc after disc.

CONTROLLED FIRING DEFORMATION

With its different composition layers, high precision shrinkage and stable CTE values are achieved by controlling the whole process from refining to molding. Extensive quality control in combination with unique in-house developed raw materials deliver our best zirconia of all time. KATANA™ Zirconia YML and STML are shown here with body layer thickness adjusted to 0.4mm for YML, and 0.8mm for STML. The body layer of YML can be adjusted thinner than that of high translucency zirconia, increasing its translucency even more.

MARGINAL STABILITY

KATANA™ Zirconia YML shows sharp margins and less chipping, thereby leading to better marginal fit. Thinner restorations show that this good result in sharp margin supports the use of KATANA™ Zirconia YML. Even if the restoration margins have been milled to a very thin profile, they still show smooth margins without any chipping.
