Multilink N resin cement is a dual cure luting composite.
- Universal luting cement.
- Dual cure.
- Dispensed from automix syringe.
- 2 shades
- Transparent
- Yellow
Pros:
- Universal resin cement. Can be used to lute precious and non precious alloys, all ceramics made of zirconium and aluminium oxides and silicate ceramics.
- It’s dual cure nature is useful in situations where access to light is hampered or restricted, as in, oxide ceramics, opaque glass ceramics and metal alloys.
- It is dispensed from an automix syringe and hence it’s mixing ratio is consistent.
- Flexural Strength of 136 MPa
- Shear bond strength to dentin – 26 MPa ; enamel – 15 MPa
- Low water absorption
- Low water solubility
- High radiopacity
Cons:
- If a dry working field cannot be maintained, Multilink N should not be used.
- Interacts with phenolic substances (like eugenol) and inhibits polymerisation. Hence, mouthwash and eugenol containing temporary cements should not be used.
- Hydrogen peroxide and other oxidative disinfectants interacts with initiator system of Multilink N Primer and impairs the curing process. Hence, they should not be used to disinfect Multilink N.
How to use Multilink N Resin Cement
- Clean the tooth with polishing brush and fluoride free paste.
- Isolate the tooth.
- Try-in the restoration. if required make adjustments using fine diamonds at medium speed . Polish the surface of the restoration.
- After try-in, rinse the restoration with water and dry with air.
- Condition the restoration
- For glass ceramic and lithium disilicate glass ceramic, etch with 5% hydrofluoric acid for 60 sec and 20 sec respectively. Thoroughly rinse and dry.
- For zirconium oxide, metal supported and composite, sandblast the inner surface according to manufacturers specification. Thoroughly rinse and dry.
- Apply Monobond N on the fitting surface of the restoration with a microbrush and allow to react for 60 secs. Then disperse it with air.
- Apply Multilink N Primer A & B (in ratio of 1:1 drop) on the entire bonding surface of the tooth using a microbrush and scrub it for 30 secs. Then disperse it with blown air. The solution once mixed is to be used withing 10 minutes, or fresh solution prepared.
- Use a new automix tip, Multilink N to directly dispense on the fitting surface of the restoration.
- Seat the restoration immediately. Remove excess cement with a microbrush. Flash cure the excess cement for 1 to 3 sec and remove the excess cement with a scaler in the jelly state. Finally light cure the margins of the restoration for 20 secs.
- Finish and polish the margins.

Review of Multilink N Resin Cement
I have not looked beyond Multilink N Resin Cement for cementing my all-ceramics except for veneers (for which I use Variolink N)
I am still old school in case of metal ceramics and always go with Glass Ionomer Cement there.
Also I lute most of my zirconia crowns with Glass Ionomer cement.
There are 2 reasons for that.
One, use of GIC is much less technique sensitive when compared to resin cements.
Secondly, adhesive bonding systems (such as resin luting cements) have shown improved bond strength with zirconia in cases of compromised retention, the studies have not been conclusive in cases when primary retention is adequate.
Uno degli svantaggi più importanti quando si tratta di pillole di potenza è il loro prezzo. Sì, se qualcuno si chiede quanto costa generico Cialis e vuole acquistare un farmaco con un effetto così forte , deve essere pronto a pagare un po ‘più che per gli integratori
Regardless, studies have shown and I have found it holding true in my clinical experience too, that sandblasting the fitting surface of metal ceramic or zirconium oxide crowns, leads to better bonding and reduced deluting. This is true again for both GIC or Multilink N resin cement.
Multilink N resin cement, though has an elaborate ritual and not as simple as say RelyX Unicem 2 self adhesive resin cement, where no primer or bond is required. This definitely adds to the chairside time.
As your experience grows, you will find certain materials will work better in a certain situations. We don’t have one material which responds to every situation. Hence, you will have to keep experimenting. Studies and other’s experience will give you a hint, remaining is your use of the material. Never stop to experiment with something which is new and exciting but never try to invent the wheel either.
Mulitlink N is easy to use and with proven long term success. It ticks most of the boxes a practitioner will look for in a luting resin cement.
