Vita Lumex AC Gingiva 12 g Leucite-Reinforced Glass Ceramic Powder

VITA Lumex AC Gingiva 12 g — Leucite-Reinforced Glass Porcelain Powder

Leucite-reinforced glass ceramic with an innovative material formula suitable for common all-ceramic framework materials such as ZrO₂, lithium disilicate, feldspar ceramic, and titanium. Can also be used for framework-free restorations (e.g. veneers). Class IIa medical device category — superior colour accuracy and durability for dental restorations.

Advantages

• Excellent colour accuracy and light dynamics for a reliable natural appearance
• Excellent modeling properties — good micro-retention of ceramic particles and ideal grain-size distribution for high stability
• Dimensional stability — homogeneous structure and high density with minimal firing shrinkage
• High fracture resistance from the leucite-reinforced glass-ceramic matrix
• Reliable bonding to the framework
