Preparing the restoration for Combination Firing
Larger restorations (partial crowns and crowns) made of IPS e.max CAD must be secured on a Crystallization Pin with
IPS Object Fix Putty of Flow. This supports the restoration during the crystallization process and thus prevents warping.
Please observe the following procedure:
– Thoroughly clean and dry the restoration after clinical try-in.
– Select the largest possible IPS e.max CAD Crystallization Pin (S, M, L) that best “fills” the inside of the restoration, but
does not come into contact with the circular crown walls.
– Fill the inside of the restoration with IPS Object Fix Putty or Flow up to the restoration margin.
– Press the selected IPS e.max CAD Crystallization Pin deeply into the IPS Object Fix Putty or Flow material so that it is
adequately secured.
– Smooth out displaced auxiliary firing paste using a plastic spatula (e.g. OptraSculpt) so that the pin is securely in place
and the restoration margins are optimally supported.
– Prevent contamination of the outer restoration surface. Clean off contamination with a brush dampened with water and
dry.
Immediately reseal the IPS Object Fix Putty/Flow syringe after extruding the material. Once removed from
the aluminium bag, the syringe is ideally stored in a re-sealable plastic bag or a container with a humid
atmosphere.
This IPS e.max CAD Crystallization Pin is too small and thus unsuitable Select the largest possible IPS e.max CAD Crystallization Pin
