Investing
– During investing, make absolutely sure that the screw cavity is
entirely filled with investment material so that no ceramic material is
pressed into it!
– For further notes on investing, see page 24.
Divesting and removal of the reaction layer
For divesting, please observe the notes on page 29. To divest the pressed over abutment, the following additional notes
have to be observed:
– Fine divestment is carried out with polishing beads at 2 bar (30 psi)
pressure. Blast the exposed areas of the abutment with particular
care.
– As soon as the screw cavity is accessible and the abutment/implant
interface is free of investment material, the polishing aid is screwed
on for protection.
– The removal of the reaction layer in the IPS e.max Press Invex Liquid
is also carried out with the polishing aid screwed into place.
