What Are Zirconia Blocks? Why Dentists Trust Them
Zirconia blocks are pre-sintered ceramic blocks made from zirconium dioxide (ZrO₂), widely used in dental labs and clinics for fabricating crowns, bridges, implants, and more. Thanks to their high strength, natural translucency, and biocompatibility, zirconia blocks have become a trusted material for durable and aesthetic restorations.
Our Types: Multilayer / White / Pre-Shaded Zirconia
We offer three main types of zirconia blocks:
Multilayer Zirconia Blocks
Seamless color gradients from cervical to incisal for natural aesthetics.
White Zirconia Blocks
High-purity zirconia with customizable coloring liquids.
Pre-Shaded Zirconia Blocks
Pre-stained in VITA 16 shades and bleach colors to simplify workflow.
All blocks are available in 98mm, 95mm, and 92*75mm sizes, compatible with open CAD/CAM systems.
