Cementation

Basically, adhesive cementation (Variolink II) should be the objective. If there are clinical reasons that speak against adhesive cementation, crowns which were fabricated with the IPS Eris layering material may also be cemented with Pro Tec CEM (VIVADENT).

• Hybrid ionomer cements with higher degrees of expansion than Pro Tec CEM must not be used.
• Restorations fabricated with the IPS staining materials or the old IPS Empress layering materials must be seated using the adhesive technique.

If the adhesive method is impossible to use:

Conventional cementation should be carried out only...

• in areas where adhesive cementation can not be achieved
• if adequate retention is achieved, and
• if the restoration was fabricated with the IPS Eris layering material.
