At Kuraray Noritake Dental, we understand that the most important factors for successful prostheses are strength and aesthetic appearance. With our KATANA Zirconia multilayered series, we are proud to provide a range of materials with the translucency, colour gradient and durability to make every prosthesis as natural as possible, from veneers to full-contour restorations.

Launched in 2015, KATANA Zirconia UTML (Ultra Translucent Multi Layered) is the most translucent series at 43 per cent, a level equal to that of lithium disilicate or glass. This optimal translucency, combined with its natural colour gradient, allows the material to be used with confidence for veneers and crowns between natural teeth in the anterior region. KATANA Zirconia UTML is available in 20 shades in two shade groups (standard and enamel), with the reduced chroma of the enamel shades allowing for an enhancement of the translucency of the incisal area. As the flexural strength of KATANA Zirconia UTML—557 MPa—is 30 per cent higher than that of lithium disilicate, it can be reliably used to produce durable and aesthetic single restorations.

KATANA Zirconia STML (Super Translucent Multi Layered) likewise has a natural colour and translucency gradient that transmits light in the incisal area while blocking it in the cervical area. This provides clinicians with the basis for beautiful full-contour prostheses, regardless of the abutment colour. With a translucency of 38 per cent and a flexural strength of 748 MPa—even higher than that of UTML, this series is recommended for up to three-unit posterior bridges, as well as crowns in the anterior and posterior regions.

The KATANA Zirconia ML (Multi Layered) and HT (High Translucent) series possess a flexural strength of 1,125 MPa, providing the highest level of mechanical strength in the KATANA line. Ideal for frameworks and long-span bridges, this series has a translucency of 31 per cent and ensures the aesthetic appearance of zirconia required by Kuraray Noritake Dental.

Give your brush a break
Often, the only way to ensure a prosthesis’s natural appearance is by dipping. With the KATANA Zirconia series, prostheses simply need to be milled and sintered to create natural aesthetics. To give them an even more natural look, the buccal surface can be stained with FC Paste Stain (Cerabien ZR).

Introducing the KATANA Zirconia Block
At the 2017 International Dental Show, Kuraray Noritake Dental debuted the latest addition to the KATANA range: the KATANA Zirconia Block. Designed specifically for compatibility with Dentsply Sirona’s CEREC system, the combination of excellent materials and advanced equipment means that full-contour zirconia restorations can be milled in 15 minutes and fabricated within 45.

Cementation with PANAVIA
Built upon the foundation of our original MDP monomer, PANAVIA cements are the best option for cementing prostheses or bonding to zirconia in a dental practice or laboratory. Both PANAVIA V5, developed for all indications, and PANAVIA SA Cement Plus, designed for ease of use, utilise the MDP monomer and have high bond strength to zirconia and durability. With PANAVIA cements, restorations can be cemented adhesively, expanding the options for use with zirconia.
