When it comes to the aesthetic performance of restorations in the anterior region, a key aspect to consider is translucency—the ability of the material to let light pass through it without becoming transparent. As teeth are naturally quite translucent, it is often noticeable if a restoration is of a low-translucency material, as it will not blend in. In addition, if the material is of a different colour to the surrounding teeth, it will likely appear unnatural. As the originators of multilayered zirconia technology, Kuraray Noritake Dental is proud to present our KATANA Zirconia range, a ceramic solution for restorative procedures that, owing to its superior translucency and variety of shade options, blends with the surrounding dentition perfectly.

Though it has been used in restorative dentistry since around 2000, zirconia’s popularity as a metal-free alternative has risen dramatically with the recent development of high-translucency options. Whereas older generations of this material possessed an unnatural, chalk-like whiteness that diminished its appearance, newer versions combine mechanical performance with visual superiority to effectively mimic the shading differences between the enamel and dentine layers. Our KATANA Zirconia line is at the forefront of this new standard, as its enamel-like translucency and durability make it suitable for full-contour zirconia crowns, veneers and inlays/onlays in the anterior region. KATANA Zirconia’s multilayered technology builds upon our emphasis on research and development to provide a highly aesthetic and biocompatible restorative material.

A pioneering spirit
Much of the advancement in zirconia’s translucency has been the result of innovations in the powder that forms the basis of the blocks and discs. Whereas a vast majority of zirconia manufacturers rely on a single, shared provider of this powder, Kuraray Noritake Dental’s powder is proprietary and processed in-house. This pioneering spirit allows KATANA Zirconia to have as natural a translucency and colour as possible—the KATANA Zirconia UTML (Ultra Translucent Multi Layered) series possesses a translucency of 43 per cent and is available in 16 standard shades and four enamel shades, making it an ideal and harmonious fit for almost all anterior restorations between natural teeth.

Our KATANA Zirconia disc range consists of several options designed for full-contour zirconia prostheses, from single crown to full arch: KATANA Zirconia UTML, STML (Super Translucent Multi Layered), ML (Multi Layered) and HT (High Translucent). The KATANA Zirconia Block, specifically designed for compatibility with Dentsply Sirona’s CEREC system, is similarly multilayered and allows for milling of zirconia restorations in just 15 minutes and fabrication within 45. The multilayer build-up of KATANA Zirconia means that, like in natural dentition, the translucency of restorations made with this material is higher in the incisal than in the cervical areas. Each of the KATANA Zirconia series possesses different translucency and mechanical properties, allowing clinicians to cover a wide range of restorative cases in the anterior and posterior regions.

“The KATANA Zirconia range demonstrates our commitment to providing aesthetic and reliable products for clinicians worldwide,” said Eileen Tan, European Product Manager at Kuraray Dental Benelux. “With KATANA Zirconia, you can bring true naturalness to your prostheses.”
