Repairing of temporaries
If Telio CS C&B temporaries are relined, repaired or adjusted, the following procedure is
recommended:
Telio CS C&B temporaries can be repaired with freshly mixed Telio CS C&B after having
conditioned them with AdheSE Bond or Heliobond.
1. Grind the areas of the Telio CS C&B temporary which need to be relined, repaired or
adjusted with a coarse diamond.
2. Apply AdheSE Bond / Heliobond.
3. Disperse AdheSE Bond / Heliobond with a very weak stream of air. Avoid pooling!
Care should be taken not to blow away the bonding agent. All the prepared
surfaces must be adequately coated with AdheSE Bond / Heliobond.
Note: AdheSE Bond / Heliobond does not contain a solvent that has to be
evaporated!
4. Polymerize AdheSE Bond / Heliobond for 10 s using an LED or halogen curing light
with a light intensity of more than 500 mW/cm 2 (e.g. bluephase in the LOP mode). If
other curing lights are used, the recommendations of the respective manufacturer
must be followed to obtain fully polymerized results. The curing time depends on
the light intensity and the wavelength range of the light emitted by the different
curing units. Curing times of less than 5 s are not recommended.
5. Apply Telio CS C&B.
6. If necessary, finish the relined, repaired or adjusted areas of the Telio CS C&B
temporary with e.g. cross-cut tungsten carbide burs and subsequently polish them
with silicon carbide rubber polishers (e.g. OptraPol®).
Alternatively, Telio CS C&B temporaries can be repaired or adjusted directly with a light-
curing Ivoclar Vivadent composite (e.g. Telio Add-On Flow, Tetric EvoFlow). In this case,
the respective Instructions for Use must be observed.
Telio Add-On Flow is cured with a high-power curing light (>1000 mW/cm
2 ; e.g.
bluephase) in 15 s per segment or with a standard curing light (>500 mW/cm 2 ) in 30 s
per segment. Tetric EvoFlow ® is cured with a high-power curing light (1000 mW/cm 2 ;
e.g. bluephase) in 10 s per segment or with a standard curing light (500 mW/cm 2 ) in
20 s per segment.
If the retention is insufficient or in the case of older temporary restorations, the bond
to composites can be increased by carrying out the following pre-treatment:
Grind the area to be repaired or adjusted and subsequently apply Telio Activator
extraorally. Agitate the Telio Activator for at least 30 s over the entire surface using
an application brush in order to achieve even distribution and quick penetration.
Subsequently, allow the Activator to react for another 30-60 seconds (total reaction
time 1-2 minutes). Now apply the Heliobond bonding agent, thinly disperse it with
blown air, and polymerize for 10 seconds (650 mW/cm
2 , e.g. bluephase using the
LOP mode).
Apply Telio Add-On Flow or another light-curing Ivoclar Vivadent composite (e.g.
Tetric EvoCeram or Tetric EvoFlow) and cure according to the Instructions for Use.
