10 Instructions for useFramework preparation1Framework preparation and cleaningFigure 1: There is no need to finish the sinteredCercon base framework with rotary instruments.The framework surface is rendered sufficientlyrough by the milling process to facilitate a mechanicalbond.Minor final corrections, e.g. marginal corrections,should be performed using diamond instruments.To avoid microcracks, any grinding or cutting ofthe framework should be performed using ahigh-speed motor and water-cooling. Keep thepressure on the framework material to a minimumin order not to overheat it.To avoid tension in the ceramic veneer, any sharpedges or corners of the frameworks must berounded.Frameworks with cracks or holes are unsuitablefor processing; an error-free, durable veneer ofsuch frameworks is not possible.The prepared zirconia frameworks are sandblastedwith alumina (110–125 µm, 3–3.5 bar).Then the frameworks are cleaned by steam or ina clean ultrasonic bath.Applying the linerFigures 2–6: The Cercon base structure ce ramicmaterial is first prepared by applying the liner.This will give the crown its basic underlying shade.Applying the liner as two thin but covering layers isrecommended for the standard build-up techniqueand for an accurate reproduction of the V shadesboth for non-colored frameworks (Cercon base)and for colored frameworks (Cercon base colored).In the individual build-up technique, the liner canbe applied in a single layer or left out completely.The liner does not influence the bond strength,which is not reduced if the liner is omitted. Whenworking with only one layer of liner or with no

It might be worthwhileto remember that there are more than 40 dif -ferent phosphate cements, some of them withdifferent shades. The same is true when usingadhesive resins.
