polymerization of the luting composite used for the
permanent cementation of the final restoration.
To prevent Telio CS Link from permanently adhering to
composite-based core build-up material, freshly placed and
prepared composite cores should be coated with a thin lay-
er of separator. Water-soluble glycerine gel (e.g. Liquid
Strip) may be used for this purpose. Following cavity prepa-
ration, no dentin adhesives or protective varnishes should
be used prior to the application of Telio CS Link.
Application
1) Remove the cap of the 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 dou-
ble-push syringe has been used before, replace the used
mixing tip with a new one just before dispensing 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 it
1/4 turn clockwise. The double-push syringe contains
predosed amounts of Telio CS Link base and catalyst
which are automatically mixed and dispensed when
the two components are extruded. Thus the material
may be directly applied to the provisional restoration.
3) Spread a layer of Telio CS Link over the dry inner
surfaces of the provisional restoration and/or the
prepared, cleaned and dried tooth surfaces. The working
time is approx. 2.5 to 3 minutes at a room temperature
of 23 °C/73 °F. Incorporation of Telio CAD temporary
restorations: Abrade the inside surfaces of the restora-
tion by abrasive (with Al

O

, 100 µm grit at 1-2 bar/15-
29 psi) or with a coarse diamond bur.
4) Seating of the provisional restoration and removal of
excess cement
Seat the provisional restoration with firm but light pres-
sure. Excess cement can be removed using different
methods.
4a) Removal of excess with additional light-activation
(quarter technique)
Light-cure excess material with the polymerization light
(approx. 650 mW/cm
2 , e.g. bluephase, LOP mode,) for
2-4 seconds per quarter surface (mesio-oral, disto-oral,
mesio-buccal, disto-buccal) at a distance of approx.
0-10mm. Following this, the excess material can be eas-
ily removed with a scaler as it features a viscoplastic
consistency. Subsequently, light-cure all margins again
for 10 seconds (light intensity > 1,000 mW/cm
2 , e.g.
bluephase, HIP mode).
4b) 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 minutes) or accelerate the
polymerization process by light-curing the cement layer
with a curing light (light intensity > 1000 mW/cm
2 , e.g.
bluephase ® , HIP mode) for 10 seconds per aspect.
4c) 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.
Leave the used mixing tip on the syringe.
It will serve as a seal until the next use!
Special notes
– To ensure an easy clean-up and complete removal of
excess, we recommend holding back the lip or cheek
surfaces during the setting process, to prevent the
excess material from spreading out into a thin layer.
– During the self-curing process, the patient should not
exert any pressure on the provisional restoration.
Working time
Approx. 2.5 to 3 minutes at a room temperature of
23 °C / 73 °F.
Self-curing time
Four minutes at a temperature of 37 °C / 98 °F.
Exposure to light will accelerate the curing process.
