Self-Adhesive Cementation of Zirconia or Metal - TheraCem
The self-adhesive cementation of zirconia or metal restorative procedure utilizes self-adhesive resin cement to lute restorations with minimal steps.
BISCO Recommends
TheraCem is selected as a dual-cure resin cement that supports simplified cementation workflows by reducing the need for separate bonding agents while maintaining compatibility with zirconia and metal substrates.
See below for the Step-by-Step technique.
STEP 1
Sandblast
Metal/Zirconia/Indirect Composite: Sandblast internal surface of restoration, unless restoration has been previously sandblasted.
STEP 2
Temporary Restoration
Remove temporary restoration and clean prep with pumice and water slurry. Rinse thoroughly and dry.
STEP 3
Occlusion
Try-in to check occlusion and fit. After try-in, thoroughly rinse the restoration with water spray and dry.
STEP 4
Cementation
Using a dual-cured resin cement (Duo-Link Universal), fill the internal surface of the restoration and/or the prep with the cement. Seat with gentle, passive pressure and remove excess cement while holding restoration in place. Allow the cement to self cure, or light cure each surface of the tooth for 40 seconds.
