What is Z-PRIME Plus?
Z-Prime Plus is a single-component priming agent designed to enhance adhesion between indirect restorative materials and resin cements. It is used as a surface treatment for zirconia, alumina, metal/alloy, composite, endodontic posts and intraoral repairs.
Is Z-PRIME Plus compatible with all resin cements?
Yes, Z-Prime Plus is compatible with all light-, dual- and self-cured cements from all manufacturers.
What is the shelf life of Z-PRIME Plus?
Do I need to refrigerate Z-PRIME Plus?
No. Z-Prime Plus may be stored at room temperature.
Do I need to shake Z-PRIME Plus prior to use?
There is no need to shake the bottle, as Z-Prime Plus is always homogeneous.
Does Z-PRIME Plus affect the final seating of the restoration?
No, Z-Prime Plus has a film thickness of only 2 µm. Z-Prime Plus does not need to be light-cured.
After dispensing, how much time do I have to use the Z-PRIME Plus?
Z-PRIME Plus is a light sensitive material. Use Z-PRIME Plus immediately once it is dispensed in the mixing well or protect from ambient light.
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 bond that allows you to predictably bond resins to that surface. Application of Z-Prime Plus provides a strong chemical bond to all metals, zirconia, alumina and composite surfaces. One product cannot achieve high chemical bonds to all of these substrates. Materials that combine both these primers do not provide a chemical bond to glass ceramics, the only benefit of application of those materials is from substrate “wetting” effect.
Do I need to decontaminate my zirconia crown after try-in?
Yes, if you hope to achieve optimal and reliable cementation results. Removing contaminants from the restoration will help to achieve better bond strengths. If the crown has been sandblasted, then after try-in, clean the internal surface of the zirconia with ZirClean®, and then proceed with applying Z-PRIME Plus. If the surface wasn't sandblasted, then sandblast the intaglio surface of the zirconia, clean the internal surface of the zirconia with ZirClean, and then proceed with applying Z-PRIME Plus.
