Vita Lumex AC Mamelon 12 g Leucite-Reinforced Glass Porcelain Powder

Lumex AC Mamelon 12 g — Leucite-Reinforced Glass Porcelain

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. Also usable for framework-free restorations (e.g. veneers). Class IIa medical device offering superior shade accuracy and durability in dental restorations.

Advantages

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