Sintering Zirconia Dental Materials CAD CAM Milling Dental Zirconia Blocks For D98 System
Dental Zirconia Block Feature
high flexural strength, fracture resistance, exceptional durability, and easy milling properties with precision. Pre-shaded zirconia disc consisting of three pre-colored layers Easy Handling: Polish or Glaze after Sintering Ideal for full contour crowns and bridges.
Dental Zirconia Block Benefits
Reduce preparation dramatically No need for porcelain Restoration seated firmly Eliminates the possibility of porcelain chipping No need to take out restoration under imaging medical examinations fast and efficient sintering technology Unique coloring changing effect No need for coloring liquids For open systems with different sizes such as Wieland, Sirona, Zirconzahn, Kavo, Lava, Amann Girrbach, Cercon, Dentmill etc.
Dental Zirconia Block Introduction
Yurucheng zirconia block has high strength, excellent permeability and color aesthetic repair effect that suitable for CAD/CAM system and manual system.
Dental Zirconia Block Advantages
High density and strength.
(1) The strength is 1.5 times higher than the second generation of EMPRESS.
(2) The strength is more than 60% higher than INCERAM alumina.
(3) Unique crack resistance and tough curing performance after cracking.
(4) Porcelain bridges with more than 6 units can be made, which solves the problem that all-ceramic systems cannot be used as long bridges.
Dental Zirconia blocks
1. Natural color. Compared with the color of traditional porcelain teeth, the color of zirconia porcelain teeth is naturally smooth, realistic in appearance and strong in transparency.
2. Good biocompatibility. It has no irritation, no allergic reaction to the gums, and no black line of the gums is formed. It is very suitable for oral cavity and avoids the allergies, irritation, corrosion and other unpleasant stimuli caused by traditional metal porcelain teeth in the oral cavity.
3. The tooth body has high strength and hardness. The unique resistance to rupture and strong curing properties after rupture make the tooth stronger.
4. High precision and good edge adhesion. The zirconia porcelain teeth ensure the accuracy of the inner crown of the mold and excellent edge tightness, so that the porcelain teeth made are very close to the patient's oral abutment.
