Vita Lumex AC Dentin 50 g — Leucite-Reinforced Glass Ceramic Powder

Lumex AC Dentin 50 g — leucite-reinforced glass ceramic powder

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

Advantages

• Excellent shade accuracy and light dynamics
• Excellent modelling properties with micro-retention and ideal particle-size distribution
• Dimensional stability — minimal firing shrinkage
• High fracture resistance from the leucite-reinforced glass ceramic matrix
• Reliable bonding to the framework
