Moisture Levels Vary. Our Bond Won't.
Prime&Bond active introduces the new, patented Active-Guard Technology. Our formulation provides well balanced hydrophobic and hydrophilic properties to ensure complete coverage and penetration at varying moisture levels. So even if dentin is overly wet or dry, you get a reliable bond that actively guards against the leading causes of adhesive failure.

Active moisture control
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 may weaken the bond and may cause post-operative sensitivity. If dentin is overly dried, collagen fibers can collapse and prevent effective sealing. Prime&Bond active overcomes the surface tension of water and spreads across dentin and into dentinal tubules to form an even, homogeneous layer. Upon air-drying, the solvent and water evaporate together, leaving a consistent coating of adhesive across the entire surface to ensure a strong bond.
Active cavity spreading for Prime&Bond active vs Scotchbond Universal¹ & iBOND Universal¹
Inherent surface tension prevents other adhesives from spreading easily across the surface of the cavity. Dry spots that remain unbonded can weaken the restoration and may lead to post-operative sensitivity and microleakage. Prime&Bond active is formulated to spread actively, minimizing the risk of inadvertently leaving dry spots.
Low film thickness
Thick adhesives can have a tendency to pool in the corners of the proximal box of a Class II restoration. These adhesive pools can show up as translucent areas on a radiograph, which can easily be misdiagnosed as a void, gap, or secondary decay, leading to unnecessary replacement. Thicker adhesives may also change crown prep geometry, impacting crown fit. Prime&Bond active self-levels to actively create a thin, uniform adhesive layer.

What exactly makes Prime&Bond® active so unique regarding its technology and handling? Why is Prime&Bond® active NOT just another universal adhesive?
FAQs
No, Prime&Bond active is not radiopaque. The low film thickness and the self-levelling properties help to reduce the risk of adhesive pools that might become visible on radiographs as grey areas which can be misdiagnosed as recurrent decay.
The competitive adhesives are not radiopaque neither- with one exception: Optibond FL¹.
Optibond FL contains glass fillers, resulting in an extremely high film thickness and the need to make it radiopaque. However, its radiopacity is very low, making it difficult to clearly identify it on the radiograph.
No.
Isopropanol (=alcohol) and water.
As long as the dentin is not exposed to the etchant for more than 15 seconds, there is no negative impact.
No. When used with Calibra Ceram, Prime&Bond active does not require any activators. However, when using Prime&Bond active with any other dual- or self-cure resin material (e.g. Core.X-flow, Calibra Automix or competitive materials), it has to be mixed with Dentsply Self-Cure Activator.
The pH value of Prime&Bond active is 2.7.
Prime&Bond active contains MDP and thus can be used instead of a primer for restorations made of zirconia or metal.
However, glass ceramic restorations (e.g CEREC Tessera), should be pre-treated according to the manufacturer´s instructions, e.g. with silane.
