4. The preparation or cavity should be just dry enough that the
surface has a slightly glossy appearance. Over drying can lead
to post-operative sensitivity.
5. Try in restoration to ensure proper fit. Adjust if needed.
Thoroughly clean the bonding surfaces of the restoration.
6. Remove the syringe from the foil pouch.
7. Note the date the syringe was removed on the syringe label.
8. Remove the sealing cap from the syringe.
9. Check the syringe openings for blockage; remove any paste
plugs.
10. Before the first use or after a long interval between uses,
squeeze out a small quantity of paste onto a pad to equalize
the base and catalyst paste in the syringe. Discard the paste
which has been squeezed out.
11. Attach a new mixing tip and secure it by turning it to the right.
12. Squeeze out and discard a peppercorn-size quantity until an
evenly mixed paste in a homogenous color flows out of the tip.
13. The paste requires a certain amount of time to flow through
the mixing tip. The flow through speed cannot be accelerated
by increasing the pressure on the plunger.
14. As soon as the pressure on the plunger decreases, the material
flow stops and the paste begins to set up. Do not use force to
press out paste that has set as this could cause damage to the
mixing tip and the syringe.
Dispensing of the material can be done as follows:
Inlay/Onlay – Dispense the cement directly into the cavity
preparation covering all surfaces. Seat the restoration gently onto
the tooth prep, allowing the cement to flow from all sides.
Crown – Dispense the cement directly into the restoration,
covering all surfaces. Seat the restoration gently onto the tooth
prep, allowing the cement to flow from all margins.
Post – Prepare the post space. Size and fit the post. Dispense the
cement onto the post or directly into the canal space. Seat the post
and vibrate slightly to avoid trapped air. Allow the cement to
slowly flow from the canal space.
