Built for Longer Bridge Spans
The 18mm disc gives labs the extra vertical room needed for longer bridge cases and slightly more complex framework designs, while keeping the same factory-shaded consistency that defines st pre shaded zirconia. It’s a solid choice when a case calls for more depth than standard crown work.
This size remains part of the core st pre shaded dental zirconia blocks offering, built to the same tight milling tolerances as the rest of the line.
Key Advantages at 18mm
- Extra depth for st pre shaded zirconia for crowns and bridge cases spanning multiple units
- Works well with glaze/stain enhancement
- Predictable post-sinter fit and marginal accuracy
- Compatible with rapid and conventional sintering cycles
Every 18mm disc is produced as part of our st pre shaded zirconia discs collection, giving technicians the same reliable shade accuracy found across every thickness in the range.
