Lithium Disilicate blocks

Lithium Disilicate blocks are advanced machinable ceramics ideal for high-strength and aesthetic dental restorations. Designed for CAD/CAM systems, these amber ceramics offer outstanding performance for a variety of dental prosthetics, from veneers to crowns. With excellent translucency, durability, and biocompatibility, these blocks ensure long-lasting and natural-looking restorations.
