Polishing
Prepolishing
Carefully smooth out the ridges on the occlusal surface and proximal surfaces with rubber polishers and silicone polishing
wheels. Pay particular attention to the margins in order to avoid rendering them too short.
High-gloss polishing
The restorations are polished to a high gloss using cotton or
leather buffing wheels, as well as the Universal Polishing
Paste. Use low speed and slight pressure for high-gloss
polishing. Adjust the pressure at the handpiece, not with
the polishing motor.
In order to optimally polish the occlusal surfaces, we
recommend modifying the goat hair brushes to become star-
shaped so that only the desired areas can be polished due to
the smaller size of the brush.
Depending on the type of high gloss desired, leather buffing
wheels can be used to achieve a high shine, while cotton
buffers are used to achieve a lesser degree of lustre.
It is essential to cement SR Adoro restorations using an adhesive cementation technique.
In order to achieve a chemical bond with the luting composite, the cavity side of the restoration has to be carefully blasted

at 1 bar (15 psi) pressure in the laboratory. Following the try-in in the dental office and subsequent cleaning,
the contact surfaces are again roughened with a 25 micron finishing diamond. Finally, the surfaces are silanized (e.g. with
Monobond
® Plus) to enable a chemical bond.
