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.
