- Strong and long-lasting
- Universal application
- Easy cleanup of excess cement
The universal luting composite system Multilink N is suitable for the adhesive cementation of metal, metal-ceramic, all-ceramic, and composite resin 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.
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:
- Root posts
DIRECTION TO USE
Removal of the temporary restoration and cleaning of the cavity: Remove any residue of the temporary luting cement from the cavity or preparation with a polishing brush and an oil and fluoride-free cleaning paste (e.g. fluoride-free Proxyt). Rinse with water spray. Subsequently, dry with air that is free of water and oil. Avoid overdrying.
Note: Cleaning with alcohol could lead to dehydration of dentin.
Try-in of the restoration and drying: Next, check the shade, fit and occlusion of the restoration. 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 adjustments with fine diamonds at medium speed and with slight pressure using copious amounts of water. Polish ground surfaces.When an adhesive luting protocol with composites is used, safe isolation of the operating field – preferably with a rubber dam, e.g. OptraDam, or alternatively with cotton rolls and a saliva ejector – is required. If the dental hard tissue is contaminated with blood or saliva during the tryin procedure, it must be cleaned again.
- Pre-treatment of the restoration
- After try-in, thoroughly rinse the restoration with water spray and dry it with oil-free air.
- Completely coat the bonding surface of the restoration with Ivoclean using a microbrush or brush.
- Allow Ivoclean to react for 20 seconds. Thoroughly rinse the restoration with water spray and dry it with oil-free air.
- Use Monobond N on restorations made of lithium disilicate glassceramics or zirconium oxide ceramics (e.g. IPS e.max Press/CAD IPS e.max ZirCAD). Apply Monobond N to the cleaned surfaces using a brush or microbrush. Allow Monobond N to react for 60 seconds and subsequently disperse it with a strong stream of air
Mixing of Multilink N Primer A and Multilink N Primer B: The two primer liquids Multilink N Primer A and B are mixed in a 1:1 ratio (e.g. 1 drop Primer A and 1 drop Primer B). The mixed Primer A/B is solely self-curing and does not need to be protected against light. However, it must be applied within 10 minutes.
Application of the mixed Multilink N Primer A/B to the enamel and the dentin: Apply the mixed Multilink N Primer A/B onto the entire bonding surface using a microbrush, starting with the enamel surface, and scrub it in for 30 s. Disperse excess with blown air until the mobile liquid film is no longer visible. As the Primer is solely self-curing, no light-curing is necessary.
Note: Previous conditioning of enamel with phosphoric acid is required for Maryland bridges.
Application of Multilink N to the restoration: For each application, place a new automix tip on the syringe. Dispense Multilink N from the automix syringe and apply the desired amount onto the restoration. As the luting material will cure in the used mixing tip, it serves as a seal for the remaining contents of the syringe until needed again (replace with a new tip before the next use).
