Post-processing
After the final sintering has taken place:
▷ If required, the zirconium oxide frames can be reworked without
pressure, using a water-cooled lab turbine and suitable diamond
grinding points (recommended grain approx. 40 μm).
▷ Polish the contact surfaces to the antagonist and to the neighbour-
ing teeth to a high gloss when in high-density sintered condition.
Frame preparation for staining and glazing
After checking the fitting accuracy, contact points and occlusion:
▷ Clean the interior crown surfaces by means of corundum blasting
(aluminium oxide, 110 μm, pressure ≤ 2 bar) and subsequent ultra-
sonic treatment and/or steaming off.
The exterior crown surfaces are not corundum blasted.
For bridges with more than five units and bridges with massive inter-
mediate units, step-by-step long-term cooling to 500 °C is recom-
mended.
Staining and glazing
▷ Stain and glaze the units afterwards.
