Finishing
Important!
– Do not finish the shoulder of the ceramic structure to prevent negatively affecting the Ti base.
– Finish the emergence profile if required taking the fit to the gingiva and the minimum thickness (0.5mm) into
account.
Finishing the outer surface of the ceramic structure (hybrid abutment)
– Smooth out the attachment point to the block with fine diamond grinding instruments taking the shape of the
emergence profile and the crown margin into account.
– Do not perform any individual shape adjustments, as this will negatively affect the fit of the crown on the hybrid
abutment. Note regarding the crown: If there are any inaccuracies of fit to the hybrid abutment, adjust the crown
by grinding.
Finishing the outer surface of the ceramic structure (hybrid abutment crown)
– Smooth out the attachment point to the block with fine diamond grinding instruments taking the shape of the
emergence profile and the proximal contacts into account.
– Surface-grind the entire occlusal surface with a fine diamond to smooth out the surface structure created by the
CAD/CAM procedure.
– Check the proximal and occlusal contacts.
– Design surface textures.
– Clean the ceramic structures with ultrasound in a water bath or blast with the steam jet before further processing.
– Make sure to thoroughly remove any residue of the milling additive of the CAD/CAM milling unit. Residue of the milling
additive remaining on the surface may result in bonding problems and discolouration.
– Do not blast ceramic structures with Al

The shoulder of the ceramic structure must not be finished to prevent negatively
affecting the Ti base.
Care should be taken when finishing the emergence profile to prevent affecting
the fit to the gingiva.
