Seating/cementation of temporaries
Telio CS Link is a dual-curing (light- and self-curing) temporary composite cement to be used for the
esthetic temporary cementation of provisional restorations.
1. Remove the cap of Telio CS Link (double-push syringe) by turning it 1 /
4
turn counter clockwise (discard
the cap, do not re-use it!) and replace it with a mixing tip. If the double-push syringe has been used
before, mount a new mixing tip directly before the application of Telio CS Link.
2. When attaching the mixing tip to the syringe, make sure that the guidance of the double-push syringe
is aligned with that of the mixing tip. Push the tip completely down until the notch on the mixing tip
is aligned with that of the double-push syringe. Secure the mixing tip in place by gripping the
coloured base and turning
1 /
4
turn clockwise. The double-push syringe contains pre-dosed amounts of
Telio CS Link base and catalyst, which are automatically mixed and dispensed when the two
components are extruded. Thus, Telio CS Link can be applied directly into the temporary restoration.
3. Apply Telio CS Link on the dry inner surfaces of the temporary restoration and/or the prepared,
cleaned and dried tooth surface. The processing time is approx. 2 1 /
2
to 3 minutes at room
temperature (23 °C / 73 °F). Incorporation of Telio CAD temporary restorations: Abrade the inside
surfaces of the restoration with Al

, 100 µm grit at 1-2 bar / 15-29 psi pressure or roughen with a
coarse diamond bur.
4. Seating of the temporary restoration and removal of excess cement
Seat the temporary restoration on the prepared teeth with light pressure. Excess cement can be
removed using different methods:
a. Removal of excess with additional light-activation (quarter technique)
Activate the cement excess with a polymerization light (>650 mW/cm 2 , e.g. bluephase in the LOP-
mode) at a distance of approximately 0–10 mm for 2-4 s per quarter surface (mesio-oral, disto-
oral, mesio-buccal, disto-buccal). Excess may be easily removed with the help of a scaler once
the material is in its highly viscous state. After that, polymerize all the margins again for 10 s.
(>1000 mW/cm
2 ; e.g. bluephase in the HIP mode).
b. Removal of uncured excess
Remove uncured excess cement immediately after incorporation with a micro-brush/brush/foam
pellet/dental floss or scaler. After that, wait until the material has set due to the self-curing action
(approximately 3 minutes) or, as an option, accelerate the setting process by means of light
polymerization for 10 s per surface (>1000 mW/cm
2 ; e.g. bluephase in the HIP mode).
c. Removal of cured excess
Carefully remove cement excess after approximately 3 minutes with a scaler or other instruments.
5. Long-term temporaries (wear periods of >4 weeks) have to be checked and re-examined at regular
intervals so that the restoration can be recemented, if necessary.
Leave the used mixing tip on the syringe as a cap until the next application.
Prevention of premature loss of retention:
Apart from a retentive preparation design, the reliable cementation of Telio CAD restorations using a
temporary luting material (e.g. Telio CS Link) depends on the accuracy of fit, which is determined by
the CAD/CAM system used.
