Vita Lumex AC Classic Standard Set Leucite-Reinforced Glass Ceramic Powder

Lumex AC Classic Standard Set — Leucite-Reinforced Glass Porcelain

Leucite-reinforced glass ceramic with an innovative material formula for all common all-ceramic framework materials (ZrO₂, lithium disilicate, and feldspar ceramic), titanium frameworks, and framework-free restorations including veneers. Class IIa medical device.

Advantages

• Excellent shade accuracy and reproduction of natural tooth colours and light dynamics
• Excellent modelling properties — good micro-retention of ceramic particles and ideal grain-size distribution for high stability
• Dimensional stability — homogeneous structure and high density minimize dimensional change and shrinkage during firing
• High fracture resistance from the leucite-reinforced glass-ceramic matrix
• Reliable bonding to the framework
