Summary  TZP-A (=ZirCAD) is the strongest, toughest and most stable actual available dental ceramic  Transformation toughening (tetragonal  monoclinic)  Compatibility to IPS e.max Ceram and IPS e.max ZirPress  Sintered IPS e.max ZirCAD surface is rough  Soft blasting (< 1bar) with Al2O3 particles on the cementation surface of the framework can enhance the bonding strength due to mechanical cleaning of the surface.  No blasting on the veneering surface due to possible CTE missmatch on the veneering surface (Al2O3 & monoclinic phase) and decrease to cyclic fatigue resistance.
