Truly universal

The universal luting composite system Multilink N is suitable for the adhesive cementation of metal, metall-ceramic, all-ceramic and composite resing restorations.

The luting composite and self-etch adhesive (Multilink N Primer) of the Multilink N-System are specially co-ordinated. The self-etch adhesive seals the dentin and ensures marginal integrity and high bond strength on enamel and dentin, which is attained in only ten minutes. It provides the basis for a strong and lasting bond.

Advantages

• Strong and long-lasting bond
• Universal application
• Easy clean-up of excess cement

Indications
The universal luting composite is suitable for the placement of indirect restorations made of leucite-reinforced glass-ceramics (IPS Empress), lithium disilicate glass-ceramics (IPS e.max CAD/Press), composite resins (FRC Postec Plus, SR Nexco), oxide ceramics (IPS e.max ZirCAD), metal and metal-ceramics (IPS 99, IPS InLine System). Multilink N is used for the following indications, depending on the material used:

• Inlays/Onlays
• Crowns
• Bridges
• Root posts

Direction to Use

Removal of Temporary Restoration and Cleaning of the Cavity:

• Remove any residue of the temporary luting cement from the cavity or preparation using a polishing brush and an oil and fluoride-free cleaning paste.
• Rinse with a water spray and dry with air that is free of water and oil. Avoid over-drying.

Try-In of the Restoration and Drying:

• Check the shade, fit, and occlusion of the restoration.
• Make necessary adjustments with fine diamonds if required. Be cautious with fragile ceramic objects.
• If using an adhesive luting protocol with composites, ensure safe isolation of the operating field (e.g., rubber dam or cotton rolls with a saliva ejector).

Pre-Treatment of the Restoration:

• Rinse the restoration with a water spray and dry it with oil-free air.
• Thoroughly coat the bonding surface of the restoration with Ivoclean using a micro brushor brush.
• Allow Ivoclean to react for 20 seconds, rinse with water spray, and dry with oil-free air.
• For certain restorations (e.g., lithium disilicate glass ceramics or zirconium oxide ceramics), apply Monobond N to cleaned surfaces using a brush or micro brush. Allow it to react for 60 seconds and disperse with a strong stream of air.

Mixing of Multilink N Primer A and Multilink N Primer B:

• Mix the two primer liquids (Multilink N Primer A and B) in a 1:1 ratio (e.g., 1 drop Primer A and 1 drop Primer B). The mixed primer is solely self-curing and must be applied within 10 minutes.

Application of the Mixed Multilink N Primer A/B:

• Apply the mixed Multilink N Primer A/B onto the entire bonding surface using a micro brush, starting with the enamel surface, and scrub it in for 30 seconds.
• Disperse excess with blown air. No light-curing is necessary.

Application of Multilink N to the Restoration:

• Place a new automix tip on the syringe for each application.
• Dispense Multilink N from the automix syringe and apply the desired amount to the restoration.
• Replace the mixing tip with a new one before the next use.

Placement of the Restoration and Removal of Excess Cement:

• Seat the restoration in place and secure it.
• Remove excess material immediately with a micro brush, brush, foam pellet, dental floss, or scaler.
• For self-curing with additional light-curing (quarter technique), light-cure excess cement in quarter segments.
• Remove excess rapidly in challenging areas (proximal areas, gingival margins, pontics).
• Light-cure all the margins again for 20 seconds.

Finishing of the Restoration:

• Finish the cement joints with preparation diamonds if necessary.
• Polish restoration margins/cement joints with suitable polishers and finishing and polishing strips.
• Check occlusion and function and make adjustments if necessary.
