Glass ceramic lithium disilicate Press
ERADENT press ingots feature excellent transparency, natural color, highly biomimetic, strong compatibility and good adhesion. All-porcelain restorations made after being pressed can show more outstanding natural beauty.
Product Advantage
- Natural and vivid color, excellent aesthetic effect, excellent translucency through appropriate light scattering, vivid milky white with natural fluorescence.
- Moderate strength, strength ≥400MPa after complete crystallization, and low abrasion to jaw teeth.
- Suitable for ultra-thin veneer, more resistant to acid corrosion.
- Short processing time, suitable for chair-side dental restoration, and short waiting time for patients.
- A small amount of pigment reaction layer, more convenient operation.
- Excellent bonding performance, low probability of patients falling off their teeth.
- Easy to polish, reduce the wear of grinding head. The chip incidence is lower and the edge stability is high. Proper hardness and bending strength (not crystallized) ensure the long life of milling needles.
