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 /

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 rough 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)
Light-cure excess material with the polymerization light (>650 mW/cm 2 , e.g. bluephase in the LOP
mode) for 2-4 seconds per quarter surface (mesio-oral, disto-oral, mesio-buccal, disto-buccal) at a
distance of approx. 0-10 mm. Following this, the excess material can be easily removed with a
scaler, as it features a visco-plastic consistency. Subsequently, light-cure all margins again for
10 seconds (>1000 mW/cm
2 ; e.g. bluephase in the HIP mode).
b. Removal of excess in the unpolymerized state
Remove uncured excess material immediately after seating using a microbrush / brush / foam
pellet / dental floss or scaler. Subsequently, wait until the self-curing process is finished (approx.
3 min) or accelerate the polymerization process by light-curing the cement layer with a curing light
(>1000 mW/cm
2 ; e.g. bluephase in the HIP mode) for 10 s per aspect.
c. Removal of excess in the polymerized state
Approx. 3 minutes after having seated the restoration, remove excess material carefully 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.
