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
