KATANA™ Zirconia YML: the reinvention of multi-layered zirconia

The fact that different zirconia materials are used depending on the indication is both a blessing and a curse: Blessing because it allows dental technicians to achieve the best possible outcomes in every situation, and curse because the approach requires a extensive inventory and a lot of decisions. For those who prefer to take a more efficient route without compromising the outcomes, KATANA™ Zirconia YML is the new go-to solution. With its strong core and translucent outer layer, this new generation of multi-layered zirconia offers the properties needed for a broad indication range and easily obtained aesthetics.

KATANA™ Zirconia YML is the reinvention of the original multi-layer technology developed by Kuraray Noritake Dental Inc. (Kuraray Noritake Dental) more than a decade ago. It features new raw materials of different yttria concentrations integrated into the well-liked four-layer colour structure. The result is a disc with a well-balanced combination of chroma, translucency and flexural strength gradation.

As all body layers have a flexural strength of at least 1,000 MPa, the new zirconia fulfills the requirements for a broad range of indications even including monolithic long-span restorations. With its proven colour gradient and super-high translucency enamel layer, the aesthetic potiential is so high that it is often sufficient to opt for a monolithic design of the desired restorations and a time-saving finishing procedure such as polishing or ultra-micro layering with liquid ceramics (e.g. CERABIEN™ ZR FC Paste Stain).

The different layers in the blank are perfectly adjusted to each other through an in-house production procedure which ensures easy positioning of the restorations within the blank, a seamless multi-layer structure required for flawless aesthetics, a precise fit and predictable long-term behaviour.

The advanced fabrication and material composition comes with another advantage: A 54-minute high-speed sintering procedure is available for single-tooth restorations and bridges with up to three units. The optical and mechanical properties of the restorations are comparable to those after the alternative 90-minute or seven-hour sintering cycle.

KATANA™ Zirconia YML will be available July 1^st 2021. To celebrate the launch of the new member to our KATANA™ Zirconia family, we invite you to join us for a virtual kick-off symposium on July 3^rd, 2021 at 10:00 CET. We will show you how aesthetic outcomes are achieved with minimal effort, how design flexibility puts you in control and how the pace of procedures is accelerated without compromising quality.
