NX3 and OptiBond XTR

Oustanding versatility, even in total dark-cure mode

  • Higher compatibility with different dental substrates
  • Higher bond strength in total dark-cure scenario on dentine
  • Amine-free formula for longer-lasting aesthetics results

Bond Strength on Different Dental Substrates in Total Dark-cure Scenario

The compatibility of NX3 and OptiBond XTR delivers superior indirect bond strenghth versus two other cementation system in total dark-cure mode.



Study conducted by Dr. Carlos Munoz, State University of New York, Buffalo.


Bond Strength on Dentine in Total Dark-cure Scenario

The compatibility of NX3 and OptiBond XTR eliminates the need to light cure the adhesive, resulting in virtually no film thickness, fewer seating issues and imperceptible margins*

*Light curing of NX3 is recommended. OptiBond XTR in combination with NX3 does not require to be light-cured.

Superior Aesthetics

NX3 non-BPO catalyst paste minimizes colour shift that typically occurs during cement storage.

NX3 amine-free initiator system significantly improves colour stability for longer-lasting aesthetic restorations.



Why is it ideal for aesthetic restorations?

NX3 universal resin cement assures high translucency and great long term colour stability, rendering it ideal for your aesthetic indirect restorations.


These features, combined with unlimited working time, give you great results especially when cementing veneers. For this procedure, choose NX3 Light Cure for the highest aesthetic impact.


How does it do this?

In traditional dual-cure cements, the BPO contained in the catalyst paste can be unstable and instigate colour shift inside the syringe. The tertiary amine base reacts with the catalyst to cause further colour instability after curing.


The NX3 dual-cure, self-cure initiator system does not contain tertiary amines or BPO, resulting in higher colour stability both in the syringe and after curing.


The perfect bond

When used together, OptiBond™ XTR and NX3 combine the clarity of one, standardised process for all your indirect procedures, with outstanding aesthetic results even in total dark cure.
