What is the best bonding agent to use with Core-flo?
With any of our core build-up materials, we recommend either Bisco’s dual-cure Universal Prime
Is it possible to reduce the number of steps while maintaining the same high bond strength?
Some new universal adhesives are single-step systems, but still have bond strengths as high as multi
“Hydrophilic vs. Hydrophobic Adhesives”? What does this mean and why is it important in the development of adhesives?
Hydrophilic means having a strong affinity to water, while hydrophobic means having little or no aff
Does the water content matter in an adhesive? and why?
Unlike solvents like acetone or ethanol, water is difficult to remove during application. Residual w
How do you differentiate 7th generation adhesives from Universal adhesives?
7th generation adhesives can only be used in self-etch mode and are more hydrophilic, while Universa
Are 1-layer adhesives good enough?
Traditional one-layer adhesives were permeable, which may have caused sensitivity, faster degradatio
Why do some universal adhesives require a separate self- or dual-cure activator?
Most Universal Adhesives contain an excessive amount of water and remain acidic, even after solvent
Can self-etch adhesives etch enamel?
Mildly acidic self-etch adhesives (pH > 2.0) do not effectively etch uncut enamel, and should be

Yes, Z-Prime Plus is compatible with all light-, dual- and self-cured cements.
Why does BISCO not recommend Z-Prime Plus be used for Porcelain and Lithium Disilicate restorations?
Application of a pure silane coupling agent to glass ceramic surfaces provides a strong chemical bon
What is the possibility that I might see marginal discoloration?
In addition to proper marginal fit, the following should be taken into consideration: We recommend
Do I need to pre-treat the surfaces of my indirect restorations?
Yes. Silane should be used to prime the surface of glass ceramics. Z-Prime Plus should be used to pr
What cement should I use for cementing Lithium Disilicate restorations?
For crowns, bridges, inlays and onlays, dual-cured cement, such as DLU is recommended. For veneers,
