High-Translucency Lithium Disilicate for Precision CAD/CAM Restorations
XTCERA HT Glass Ceramic Blocks deliver the strength and esthetics of lithium disilicate in an efficient CAD/CAM format. Designed for lifelike translucency, dependable strength, and consistent precision, they provide reliable performance across both chairside and laboratory workflows.
Each block features a refined nanocrystal glass-ceramic structure that enhances light transmission while maintaining superior edge stability and resistance to wear. After full crystallization, XTCERA achieves flexural strength of ≥ 400 MPa and can reach up to ~637 MPa, ensuring long-term durability for restorations such as veneers, inlays, onlays, overlays, anterior and posterior crowns, and partial crowns.
Optimized for digital workflows, these blocks mill smoothly, crystallize rapidly, and produce a consistent, high-gloss surface with minimal post-processing. Their enamel-like translucency allows for natural shade depth and seamless integration with surrounding dentition, ideal for both esthetic and functional cases.


Advantages


High-Strength Restorations – With flexural strength above 400 MPa, XTCERA withstands precise milling and chairside adjustments while maintaining stability in function.




Ultra-Thin, Minimally Invasive – Can be milled as thin as 0.2 mm for ultra-thin veneers requiring minimal tooth preparation—ideal for chairside, minimally invasive cases.




Immediate Restoration Capability – Near 1:1 shrinkage ratio and rapid crystallization enable quick glazing, finishing, and placement with excellent marginal fit.




Aesthetic Translucency – High-Translucency (HT) material mimics natural enamel light behavior for bright, lifelike results.




Consistent Precision – Fine-grained crystal microstructure ensures smooth margins, reliable color matching, and easy polishing.




Broad Compatibility – Works seamlessly with open-architecture CAD/CAM systems (CEREC®, vhf®, Roland®, X-Mill®, and more).
