Ivoclar Vivadent Multilink Speed - Manual (Page 2)

Contraindication
Multilink Speed is contraindicated
–
in situations where the preparation does not provide adequate
retention (e.g. veneers).
– if a patient is known to be allergic to any of the ingredients of Multilink
Speed.
– In general, Multilink Speed should not be applied to exposed pulp or to
dentin which is close to the pulp.
Side effects
Systemic side effects are not known to date. In rare cases, allergic reactions
to single components have been reported.
Interactions
Phenolic substances (e.g. eugenol) inhibit polymerization. Consequently, the
application of materials containing these substances is to be avoided. Only
use eugenol-free temporary cements (e.g. Systemp
® .link), as eugenol may
inhibit the polymerization of Multilink Speed.
Disinfectants with an oxidative effect (e.g. hydrogen peroxide) may interact
with the initiator system, which in turn may impair the curing process. Thus
the tooth substance must not be disinfected using oxidative agents. Alkaline
jet media (e.g. Airflow) impair the effect of Multilink Speed.
Application
For details please refer to the individual Instructions for Use of the products
mentioned.
1. Removal of the temporary restoration and thorough cleaning of
the cavity
Remove possible residue of the temporary luting composite from the cavity
or preparation with a polishing brush and an oil- and fluoride-free cleaning
paste. Rinse with water spray.
Then lightly dry with water- and oil-free air. Avoid overdrying.
Note:
Cleaning with alcohol can lead to overdrying of the dentin.
2. Try-in of the restoration
Next, the shade, the accuracy of fit and the occlusion of the restoration can
be checked. Care should be taken when checking the occlusion of fragile
and brittle ceramic objects before they are permanently cemented, as there
is a risk of fracture. If necessary, make corrections with fine diamonds at
medium speed and with slight pressure and adequate water cooling. Polish
ground surfaces. It is essential to ensure reliable isolation of the operative
area with e.g. OptraGate, cotton rolls or saliva ejector. Dental hard tissue
contaminated by saliva needs to be cleaned again as indicated in section 1.
3. Cleaning and pre-treatment of the restoration
3.1 High-strength glass-ceramics (e.g. IPS e.max
® Press, IPS e.max CAD)
– Etch with 5% hydrofluoric acid (e.g. IPS ® Ceramic Etching Gel) for
20 seconds (IPS e.max Press, IPS e.max CAD). For all other products,
observe the instructions of the manufacturer!
– Thoroughly rinse the restoration with water spray and dry with oil-free
air.
– Apply Monobond-S or any other silanizing agent to the pre-treated
surfaces with a brush or microbrush and allow it to react for
60 seconds. Subsequently, disperse Monobond Plus with a strong
stream of air.
3.2 Clean and pre-treat the restorations made of other materials according
to the instructions of the manufacturer.
Note:
–
IMPORTANT! In order to achieve a reliable bond, do not clean
zirconium oxide and base metal surfaces with phosphoric acid.
– Contamination with saliva, blood or water must absolutely be avoided
during the entire procedure.
– In case of contamination, the entire pre-treatment of the restoration is
to be repeated (see section 3).
4. Application of Multilink Speed into the restoration
For each application, place a new automix tip on the double syringe.
Extrude Multilink Speed from the automix syringe and apply the desired
quantity directly into the restoration. As the luting material will cure in the
used mixing tip, it may serve as a seal for the contents of the syringe until
needed once again (replace with a new tip just before the next use).
5. Placement of the restoration and removal of excess cement
a) solely self-curing
Seat the restoration and retain it in place exerting uniform pressure.
Remove excess material immediately with a microbrush/brush/foam
pellet/dental floss or scaler. Make sure to remove excess material in
time, especially in areas that are difficult to reach (proximal or gingival
margins).
b) self-curing with additional light-activation to tack-cure excess
material or accelerate the curing process (quarter technique,
indicated for cases with up to 2 bridge abutments = 3- to 4-unit
bridges)
Seat the restoration and fix/hold it in place exerting uniform pressure.
Excess material is light-cured with the polymerization light (approx.
650 mW/cm
2 , e.g. bluephase ® , LOP mode,) for 1 second per quarter
surface (mesio-oral, disto-oral, mesio-buccal, disto-buccal) at a
distance of approx. 0-10mm. Subsequently, it can be easily removed
with a scaler. Make sure to remove excess material in time, especially in
areas that are difficult to reach (proximal or gingival margins). After
complete curing, the removal of excess can be difficult in these areas.
Subsequently, light-cure all cement joints again for 20 seconds (approx.
800 mW/cm
2 , e.g. bluephase C8, HIP mode) for final polymerization.
