b) immeDiatelY apply to the prepared enamel and dentine surfaces
using the disposable applicator (Fig. 4).
c) leave undisturbed for 10 seconds after applying (Fig.5).
d) then, dry thoroughly for 5 seconds with oil-free air under maXimum
air pressure. use vacuum suction to prevent splatter of the adhesive
(Fig. 6). the final result should be a thin adhesive film with the
appearance of frosted glass and that does not visibly move under
further air pressure.
note:
1) When removing from the refrigerator after long-term storage, leave
G-ænial Bond to stand at room temperature for several minutes prior
to use.
2) apply G-ænial Bond immediately as the material contains a volatile
solvent.
3) Remove excess material remaining on the tooth (other than the
surfaces to be bonded) using a sponge or cotton pellet, as residue
material is hard to remove after light-curing.
4) Should the applied material be contaminated with water, blood or
saliva prior to light-curing, rinse and dry the tooth and repeat the
procedure by re-applying material.

light-cure using a visible light curing unit (Fig. 7).
exposure time
halogen / leD (700 mW/cm²) : 10 seconds
Plasma arc (2000 mW/cm²) : 3 seconds
G-light (1200 mW/cm²) : 5 seconds
in cases where the light guide tip is more than 10mm away from the surface to be treated, light-
cure for the following times:
halogen / leD (700 mW/cm²): 20 seconds
Plasma arc (2000 mW/cm²): 6 seconds
G-light (1200 mW/cm²): 10 seconds
note:
1) light-cure completely for an effective bonding strength. lower light intensity may cause
insufficient adhesion.
2) use a protective light shield or similar protective eye wear during light-curing.
5a. Placement OF liGht-cuReD cOmPOSiteS anD cOmPOmeRS
after light-curing the adhesive, follow manufacturer's instructions for use in order to place,
contour and light-cure the selected composite resin material.
5B. Placement OF Dual-cuReD cOmPOSiteS
after light-curing the adhesive, be sure to light-cure the dual-cured composite material
separately. Self-curing only will result in insufficient bonding strength.
