Composition
The monomer matrix is composed of Bis-GMA, urethane
dimethacrylate, and triethylene glycol dimethacrylate. The
inorganic fillers are barium glass, ytterbium trifluoride,
Ba-Al-fluorosilicate glass, and spheroid mixed oxide.
Additional contents: catalysts, stabilizers, and pigments.
The particle size is 0.04–3.0 µm. The mean particle size is
0.7 µm.

Indication
Adhesive luting of ceramic, and composite restorations
(inlays, onlays, crowns, metal-free adhesive bridges, veneers
(Targis
® /Vectris ® , IPS Empress ® 2), core build-ups), made in
the laboratory or chairside.
Contraindication
The application of Variolink II is contraindicated:
– if a dry working field cannot be established, or if the
stipulated technique cannot be applied
– if the patient is known to be allergic to any of the
ingredients of the luting composite
Side effects
Systemic side effects not known to date. In individual cases,
allergic reactions have been reported. Irritation of the pulp
may occur in very deep or medium cavities, without
appropriate pulp/dentin protection or base/liner.
Interactions
Phenolic substances (e.g. eugenol) inhibit polymerization.
Consequently, application of materials containing these
substances is to be avoided.
