Vita Lumex AC Gingiva Set — Leucite-Reinforced Glass Ceramic Powder

Leucite-reinforced glass ceramic — Lumex AC Gingiva Set

Innovative glass ceramic for common all-ceramic frameworks (ZrO₂, lithium disilicate, feldspar ceramic), titanium frameworks, and framework-free restorations including veneers. Class IIa medical device.

• Excellent shade accuracy and natural light dynamics
• Excellent modeling — micro-retention and ideal particle-size distribution
• Dimensional stability — minimal firing shrinkage
• High fracture resistance; reliable bonding to frameworks
