Manufacturer’s instructions

Bottle delivery: shake Optibond Versa ADHESIVE bottle briefly prior to dispensing. Dispense 1-2 drops of Optibond Versa PRIMER and Optibond Versa ADHESIVE into two separate clean wells. Replace cap immediately after dispensing. Wet applicator tip completely.

Indications for use
Direct bonding applications
 (1) Prepare cavity. Pumice clean unprepared tooth structure with a fluoride-free cleaning paste; rinse thoroughly with water spray and air dry.
 (2) Apply Optibond Versa PRIMER to the dentin surface using the disposable applicator brush. Scrub the surface with a brushing motion for 20 seconds.
 (3) Air-thin for 5 seconds with medium air pressure.
 (4) Shake Optibond Versa ADHESIVE bottle briefly. Apply Optibond Versa ADHESIVE to the dentin surface with light brushing motion for 15 seconds.
 (5) Air-thin for 5 seconds.
 (6) Light-cure for 10 seconds.
 (7) Apply composite according to manufacturer’s instructions for use.
