Natural Color Transition,No Need Dyeing
zirconia blocksare 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.
Us zirconia blocks can be used to create crowns, bridges, inlays
and veneers of fixed partial denture with different translucency
levels and colors.

Operation Guide
1). Place zirconia block in your CAD/CAM machine and machine it
following the manufacturer’s instructions.
2). After machining is completed, remove the zirconia block from
the CAD/CAM machine first. Then remove the framework from the
zirconia block with a diamond disc. Subsequently, place the
framework on a sintering tray with zirconia beads and put them in
the oven for sintering.
3). Program the furnace according to its instruction manual and
zirconia block’s sintering chart, and then start sintering.
4). Do not remove the sintered framework until it is fully cooled
down. Examine the sintered framework for wall thickness, margin fit
and seat fit. If necessary, make minor adjustments with a water
cooled diamond tool.
5). Make sure no wall thickness is less than 0.5mm and no connector
is thinner than 9mm2.
6). Rinse the sintered framework with water and dry completely. The
