Prime&Bond active®
Universal Adhesive

A strong bond across moisture levels


97 Percent

97% of dentists confirm that too wet or too dry dentin sometimes affects the adhesive bond of their composite restorations.


Most adhesives are comparatively hydrophobic, tending to separate from water. With too much water on the prepared surface, the adhesive can’t achieve uniform coverage, leaving gaps that are likely to weaken the bond and to cause post-operative sensitivity. Additionally, if etched dentin is overly dry, collagen fibers can collapse and prevent proper sealing.

Benefits

Shear bond strength

Prime&Bond active® adhesive helps to ensure complete coverage and penetration even on overly wet or dry dentin. The result is a strong, reliable bond that protects against the leading causes of adhesive failure

Shear bond strength

Complete coverage

Inherent surface tension prevents other adhesives from spreading easily across the surface of the cavity. Prime&Bond active® adhesive spreads actively, minimizing the risk of dry spots that can cause postoperative sensitivity. It's yellow color during application improves visibility and the low film thickness and thin adhesive layer means it becomes virtually invisible after light curing

Complete coverage

Active mixing

Prime&Bond active® adhesive breaks the surface tension of the water in the prep, actively blending with it. Excess water then evaporates with the alcohol-based co-solvent to form a gap-free layer.

Active mixing

Low film thickness

Prime&Bond active® adhesive actively spreads to create a thin, uniform adhesive layer with low viscosity that helps to prevent misdiagnosis caused by pooling of thick adhesive in the corners of the proximal box.

Low film thickness

Virtually no sensitivity

On average, 10%-15% of posterior composite restorations result in post-operative sensitivity.5 In a user survey with more than 2,000 restorations, the incidence of post-operative sensitivity was less than 0.2%.6
