Question Asked on 4/30/2014
 

Why does BISCO not recommend Z-Prime Plus be used for Porcelain and Lithium Disilicate restorations?

Answer Response by Dr. Suh on 4/30/2014
 

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.
