T (Translucent)- Original Shade was released in April, 2014.
- Suitable for making frameworks on anabutment tooth.
- High strength enables long bridges.

SHT has excellent light transmission, T has high flexural strength, and HT is
designed to have a good balance of flexural strength and light transmission. For
these reasons, KZR-CAD Zr is suitable for use with a broad range of cases.

High Machining Precision by CIP andOptimal Sintering Technology
KZR-CAD Zr has excellent compatibility thanks to non-directional
CIP (Cold Isostatic Pressing) compression molding.
Carefully controlled CIP pressure and optimal sintering prevent
fractures, cracks and detachment; also, they are designed so as
to make machining precision higher.

Raw Material Composition of Zirconia Disc (Weight Percentage)

Y2O3 enables high levels of strength and fracture toughness inzirconia, as it stabilizes zirconia crystallization. The raw materials for
KZR-CAD Zr are produced by TOSOH Corporation, a Japanesecompany with a proven record worldwide. This means that
KZR-CAD Zr is a purely made-in-Japan product.

Short Sintering Time<Sintering Program>

KZR-CAD Zr sintering is completed in less than 8 hours, including
cooling time. Mass production of restorations is possible, asKZR-CAD Zr enables operation 3 times a day.
