ST zirconia blocks advantages

-- First grade Zirconia powder

-- Made under COLD ISOSTATIC UNAXIAL PRESSING AND MACHINING which gives a more uniform fit.

-- High mechanical strength reaches as high as 600 Mpa called non-fracture zirconia

-- Excellent translucent with light transmittance higher than 30%

-- Shrinkage adjusted for 20%

-- Sinterization temperature 1480 Celcius 2 hours

Natural Color Transition

zirconia blocks are made of nanometer medical grade zirconia powder. The powder are firstly compacted by cold isostaticpressing with high compressive strength and then pre-sintered to a certain degree to offer good machinability.

ST zirconia blocks can be used to create crowns, bridges, inlays and veneers of fixed partial denture with different translucency levels and colors.

Super Translucent Zirconia Block

1. Super translucency with total light transmission rate >50% (comparable to lithium disilicate)

2. Average strength over 1100 Mpa (can be used in a variety of all-ceramic restorations such as onlay/inlay, crown, bridge and so on)

3. Highly accurate Vita standard coloring liquid to meet the requirements of high standard dental restoration

4. Excellent machinability owing to unique shaping technique

5. Top quality medical-grade nanometer zirconia powder

6. Ok for Anterior + Posterior teeth
