The technician can also make the facing directly, but the use of the Cerec production makes the repair cheaper.

The plastic facing is attached using cold-cured acrylic whilst the ceramic facing is attached using the same technique as when making a ceramic filling, i.e., etching, bonding and dual cement. The ceramic facing is naturally silanised and treated in the usual way by the technician.

I have replaced more than 100 facings with ceramics with excellent results.
