NX3 Nexus™ Third Generation

NX3 Nexus Third Generation is the new esthetic permanent resin cement: Delivers unmatched esthetics Long-term color stability Universally indicated for all indirect applications, including veneers Enhanced adhesion to all substrates Great compatibility with both total-etch and self-etch (including 7th generation) adhesives Excellent handling properties (non-slumpy consistency and easy cleanup)

Yes, NX3 can be used for cementation of ceramic-based (including CAD/CAM blocks and zirconia-/alumina-strengthened ceramics), resin-based, and metal-based restorations including: 1. Veneers 2. Inlays and onlays 3. Crowns and bridges 4. Posts NX3 can also be used for adhesive bonding of amalgam restorations and as a core-buildup material.

Tack curing the cement hastens the gelling of the cement. Once the cement has gelled, it can no longer be manipulated.

*After completion of post cementation, etch (if using a total-etch adhesive such as OptiBond Solo Plus) and apply the adhesive to the prep, dry and light-cure the adhesive according to each adhesive's directions for use. *Dispense the mixed NX3 Dual-Cure around the post and onto the prepared tooth. Notes: The mixed NX3 can optionally be loaded with a Unidose tip and dispensed onto the prepared tooth. The mixed NX3 can also optionally be loaded into the appropriate CoreForm and seated onto the prepared tooth. *Clean any excess material. *The mixed NX3 will cure to a hard set approximately 6 minutes after being placed on the prepared tooth. The set may be accelerated by curing with a curing light for 30 seconds per surface. It is recommended that the light-curing be delayed for a minimum of 3 minutes to minimize the negative effect of shrinkage stress as the material is bulk-cured in this case. *Check hardness of NX3 with an explorer before final finishing. Using a diamond or carbide bur, remove any flash or excess NX3, shape and finish preparation. *The finished NX3 is ready for an impression.

Radiopacity is measured by taking an X-ray of a dental product alongside aluminum and then comparing the X-ray absorbing power (optical density) of both X-rays. If the X-ray absorbing power for the dental product is the same as that for aluminum, then the radiopacity of the dental product is 100% of aluminum. If the X-ray absorbing power for the dental product is 2 times as strong as that for aluminum, then the radiopacity of the dental product is 200% of aluminum. Dentin has a radiopacity of 100% of aluminum and enamel has a radiopacity slightly less than 200% of aluminum. To be called radiopaque, the radiopacity of the cement must be equal to or greater than that of dentin (≥ 100%). Generally, a cement with a radiopacity of less than 100% of aluminum is called radiolucent (or not radiopaque).
