Edited by Dentaltown staff

NEW YORK—Kuraray America has made all 14 shades of KATANA Zirconia ONE SPEED available, including A2 and A3, completing the shade range for the chairside zirconia material.

The material is designed for chairside zirconia restorations and features 1,023 MPa flexural strength, according to the company. When used with Dentsply Sirona’s CEREC SpeedFire, it enables a nine-minute sintering workflow that supports same-visit posterior crown restorations.

The multilayered block consists of four gradated zirconia layers: enamel, two transition layers, and body/dentin, which the company said help clinicians fabricate tooth-colored restorations chairside. Kuraray said the nine-minute sintering time is enabled by Kuraray Noritake Dental’s proprietary zirconia powder technology.

The 14 shades include NW from the Noritake shade guide and 13 shades from the VITA classical A1-D4 system: A1, A2, A3, A3.5, A4, B1, B2, B3, C1, C2, C3, D2, and D3.

To use the full shade range, the company said users should update their CEREC or inLab software; compatible versions include CEREC software 5.2.14 or newer, 5.3.5 or newer, and inLab CAM 22.8.
