Divesting
Once the investment ring has cooled to room temperature
(approx. 60 minutes), divest as follows:
– Mark the length of the plunger on the cooled investment
ring.
– Separate the investment ring using a separating disk. This
predetermined breaking point enables reliable separation
of the investment material and the ceramic.
– Break the investment ring at the predetermined breaking
point using a plaster knife.
– Always use polishing beads to divest the pressed objects.
Do not use Al

for rough and fine divestment.
– Rough divestment is carried out at 4 bar (60 psi) pressure,
while fine divestment is done at 2 bar (30 psi) pressure.
– Observe the blasting direction and distance to prevent
damage to the object margins during divestment.
Note
For long-span restorations,…
–
it is recommended to cut the sprues while the restoration
is still in the investment
ring in order to relieve
tensions before final
divestment.
– make sure not to damage
the restoration when
cutting the various sprues.
