II. Tooth Preparation
Either OptiBond Solo Plus (total-etch) or OptiBond All-In-One (self-etch) adhesives can be used
in combination with NX3.
Total-Etch Technique
OptiBond Solo Plus Directions:
1.
After thoroughly cleaning the preparations (pumice and prophy cup), etch enamel and dentin
for 15 seconds with Kerr Gel Etchant (37.5% phosphoric acid). Rinse thoroughly and air dry (or
blot dry). Do not desiccate.
2.
Apply OptiBond Solo Plus to the enamel/dentin surfaces with an applicator tip for 15 seconds
using a light brushing motion.
3.
Air thin the adhesive for 3 seconds. Avoid pooling of adhesive before light curing (for inlay,
onlay, crown, and post cementation). Remove excess adhesive with a dry applicator
brush or absorbent paper point (for post cementation).
4.
Light cure for 10 seconds.*
Self-Etch Technique
OptiBond All-In-One Directions:
1.
Thoroughly clean the preparations (pumice and prophy cup). Wash thoroughly with water
spray and air dry. Do not desiccate.
2.
Using the disposable applicator brush, apply a generous amount of OptiBond All-In-One
adhesive to the enamel/dentin surface. Scrub the surface with a brushing motion for 20
seconds.
3.
Apply a second application of OptiBond all-In-One adhesive with a brushing motion for 20
seconds.
4.
Dry the adhesive with gentle air first and then medium air for at least 5 seconds with oil-free
air.
5.
Light-cure for 10 seconds.*
III. Cement Application and Seating of Restoration
Work Time – Self-cure mode, a minimum of 2 minutes.
Clean up – Approximately 2-3 minutes after placement, or tack cure for 2 seconds for immediate
cleanup.
Note:
1.
Work time is based on material at 23°C. Clean-up time is based on material at 37°C. This
time may vary based on storage conditions, temperature, humidity, and age of product.
2.
For the dual-cure cement, bleed cartridge before initial use.
A. Veneers
Note: Both single-syringe light-cure resin cement and dual-syringe, dual-cure resin cement
(ideal for 1-2 units) can be used for cementing the veneers. For thicker veneers, a dual-cure
resin cement is recommended.
Dispense cement directly onto the internal surface of the veneer. Place the veneer gently on
the tooth, allowing the cement to slowly flow from all margins. Spot cure the veneer into
place on the facial surface away from the margins using a small diameter light guide for
10 seconds. After removing the excess cement, light cure all surfaces for a minimum of 20
seconds* per surface.
B. Crowns, bridges, inlays, onlays, and metal-based restorations
Note: On the prep, avoid pooling of adhesive before light curing of adhesive. Excess adhesive
can be removed with a dry applicator brush before light-curing of the adhesive.
Apply the dual-cure cement to the restoration or the prep. Seat the restoration gently onto the
preparation allowing the cement to flow from all sides. Remove excess cement.† Light cure
all surfaces for a minimum of 20 seconds* per surface.
† Excess cement cleanup – Excess cement is best removed in its gel state with a scaler or
explorer. Gel state can be achieved by tack curing excess with a light for 1-2 seconds or
allowing the cement to self-cure for 2-3 minutes after application.
