Bonded Cementation of Glass Ceramics

BISCO Recommends

Porcelain Etchant is used to condition the ceramic surface to support micromechanical retention. Porcelain Primer promotes chemical interaction with silica-based ceramics. Select HV Etch w/BAC supports selective enamel conditioning where indicated. All-Bond Universal is used to support adhesion to tooth structure. Duo-Link Universal provides dual-cure resin cement designed for indirect restorations requiring both chemical and light activation.

See below for the Step-by-Step technique.

STEP 7

Air Dry

Gently air dry until there is no visible movement of the adhesive. Then thoroughly air dry with greater air pressure. The surface should appear shiny, otherwise repeat step 7. Light cure for 10 seconds.**

STEP 8

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.
