Multilayer TT Zirconia Blanks
Advantage of zirconia dental:
1. High aesthetic effect, good transparency, natural tooth color.
2. High strength, hardness and durable, do not need the support of metal.
3. Excellent biological compatibility, no metal odor, no black color and no corrosion, anti allergy, protect the gums and avoid bleeding.
The zirconia disk and blocks are the finest and most pure zirconia materials , most of zirconia powder are from Japan and well compatible with all open cad cam milling machine,like Origin milling machine,Shera Milling machine.VHF milling machine.
1.All of zirconia disks with super high translucence (light transmittance 40%) are for full contour.
2.All of zirconia block with High translucence (light translucence 30%) are for dental coping and bridge.
