Dentsply Prime & Bond NT Refill Bonding Agent

Prime & Bond NT is a universal self-priming dental adhesive designed to bond light-cured composite materials and Dyract compomer materials to enamel and dentine as well as to metals and ceramic.

It combines primer and adhesive in a single bottle. It also maintains excellent bond strengths and protection against microleakage. By mixing Prime&Bond NT with Self-Cure Activator, a universal, dual-cure self-priming dental adhesive system is obtained. This system is designed to bond dual- or self-cured composites to enamel, dentine, and restorative materials even in areas inaccessible to light.

Usage:

For all types of restorations

• To obtain an optimum of marginal quality and bond strength and to avoid post-operative sensitivity, do not overetch dentine (etch dentine 15 seconds or less).

• Apply Prime&Bond NT to a moist cavity surface as overdrying of the tooth preparation has been associated with a decrease of bond strength to dentine and with post-operative sensitivity. Dry by very short (1 to 3 seconds) blasts from an air syringe or solely blot-dry with a cotton pellet.

• For an optimum of solvent concentration, efficiency of the procedure, and economy, apply adhesive directly from the bottle onto an applicator tip.

• To achieve a complete sealing of the cavity surface, apply ample amounts of Prime&Bond NT. All cavity surfaces should be saturated, which may necessitate consecutive applications of a drop of Prime&Bond NT to thoroughly wet all cavity surfaces.

• To obtain an optimum layering thickness, wait for 20 seconds after application of Prime&Bond NT and remove remaining solvent by gentle blow of air from a dental air syringe. Ease of solvent removal is one of the great advantages of acetone-based adhesives.

For indirect restorations

• Light-curing of Prime&Bond NT or of the mix of Prime&Bond NT and Self-Cure Activator applied to the prepared tooth will increase bond strength.

• If gross pooling of the adhesive is avoided, light-curing of the adhesive will not result in a high restoration thanks to the low film thickness of Prime&Bond NT.

• For most indirect procedures, where light-cured or dual-cured luting cements are used, Prime&Bond NT can be used on its own (without the need to mix with Self-Cure Activator).

• In the case of metallic restorations, light-cure the adhesive applied to the restoration prior to luting.

For use with self-cure restorative materials

• When using Prime&Bond NT in combination with a self-cured material, always mix Prime&Bond NT with Self-Cure Activator and light-cure adhesive prior to application of the restorative.

Package Contents: 1 x 3.5 ml Prime & Bond NT Bottle

For all types of restorations:
Etch dentine for 15 seconds or less.
Apply Prime&Bond NT to a moist cavity surface to maintain bond strength and minimize post-operative sensitivity. You can dry the surface with short air blasts or blot-dry with a cotton pellet.
Apply the adhesive directly from the bottle onto an applicator tip.
Ensure complete sealing of the cavity surface by applying ample amounts of Prime&Bond NT. If needed, apply consecutive drops to wet all cavity surfaces.
For an optimum layering thickness:
Wait for 20 seconds after applying Prime&Bond NT.
Remove the remaining solvent by gently blowing air from a dental air syringe. Acetone-based adhesives like Prime&Bond NT are advantageous for easy solvent removal.
For indirect restorations:
Light-cure Prime&Bond NT or the mix of Prime&Bond NT and Self-Cure Activator applied to the prepared tooth to enhance bond strength.
Avoid gross pooling of the adhesive during light-curing to maintain a low film thickness.
In most cases where light-cured or dual-cured luting cement is used, Prime&Bond NT can be used on its own without mixing with Self-Cure Activator.
For metallic restorations, light-cure the adhesive applied to the restoration prior to luting.
