Description
DD Bio ZX2 is Dental Direkt's high-translucent (HT) 3Y-TZP monolithic zirconia milling disc — the balanced all-rounder of the DD Bio family. It pairs the strength of a 3Y tetragonal chemistry with markedly improved translucency, so a single uncolored white blank covers anterior and posterior full-contour crowns and bridges with natural light behaviour after staining.
- 3Y-TZP chemistry with high-translucent (HT) optics — strength plus esthetics
- uncolored white blank — shade freely with colouring liquids
- Full-contour crowns and bridges, anterior through posterior
- Ø 98 mm open-system carrier for all common open mills
- High flexural strength supports multi-unit restorations
Why You’ll Love It
- You want one versatile blank for both front and back full-contour work
- You shade by dipping/liquid staining in the lab
- You need 3Y strength with better translucency than a classic LT blank
