Designed to provide clinicians with a chairside CAD/CAM material option that combines efficient processing with the strength and esthetics needed for use in any area of the mouth, KATANA™ Zirconia ONE blocks from Kuraray Noritake Dental allows practices to reduce material inventory.

Compatible with the CEREC Primemill and Speed Fire furnace from Dentsply Sirona, the new KATANA Zirconia ONE blocks can be milled in less than 5 minutes and sintered in a new 18-minute firing cycle regardless of block shade. This makes it possible to deliver a zirconia crown in as little as 35 minutes, according to materials provided by Kuraray Noritake.

While it mills quickly, it also causes less wear on the milling tools when compared with conventional zirconia blocks, which can potentially double the lifespan of a milling tool. The KATANA Zirconia ONE material also mills with smooth margins for accurate fit, and long lasting restorations.

While it exhibits a flexural strength of 933 MPa, the new KATANA Zirconia ONE material can be milled as this as 0.8 mm for crowns in both the anterior and posterior, and as thin as 0.4 mm for veneers.

To achieve lifelike esthetics, KATANA Zirconia ONE blocks are made of 4 layers of zirconia in gradiated shades. The blocks move from an enamel layer through a pair of transition layers to reach the dentin layer. The CEREC Move Tool can be used to position a restoration within these transitioning shades too achieve the desired esthetic outcome.

Restorations fabrication from KATANA Zirconia ONE can be finished in multiple ways with options including polishing prior to sintering, polishing after sintering, and applying stains and glazes for greater characterization and detail.

KATANA Zirconia ONE blocks are available in Crown and Bridge sizes in 14 shades based on the VITA Classic Shades.
