OPAQUER
Resin-Based Metal Opaquer

GENERAL INFORMATION

OPAQUER is a specially formulated, resin-based opaquing agent used to mask dark shades of the metallic (non-precious, semi-precious and precious) framework of dental prostheses. While masking of the metal framework is necessary for pleasing aesthetics, it is not an easy task to successfully block the dark metal hue yet not overly influence the subsequent shade of restorative materials (composite or porcelain). This requires a delicate balance of opacities, hues and chromas of coloring agents. OPAQUER successfully accomplishes this balance.

OPAQUER is a two component, dual-curable opaquing agent. An accurate shade of OPAQUER is accomplished by mixing an equal portion of the Catalyst and Base. To enhance placement and prevent slumping, the mixed opaquer can also be light-cured initially without affecting its complete chemical setting. The opaquer system is Bis-GMA resin based and compatible with most composite restorative materials.

OPAQUER is intended for use with 4th or 5th generation adhesives such as ALL-BOND 2®* or ONE-STEP®*/ONE STEP PLUS. When OPAQUER is used with a metal primer (Primer B of ALL-BOND 2) an extremely high bond strength is obtained between the metal and composite.

TECHNICAL INFORMATION

At room temperature (22°C/72°F)

Working time:    Minimum 30 sec.
Setting time:      Maximum 2 min. 45 sec.


Working and setting time will both be accelerated in the warm intraoral environment.  Also, the cement will set quickly once it comes in contact with ALL-BOND 2 primers on the tooth.

INSTRUCTIONS FOR USE

1. Clean the metal surface.

2. Sandblast for 1-2 seconds using a sandblaster or abrade with a coarse diamond bur. Rinse with water and air-dry. (Tin-plating is not required if you are using ALL-BOND 2 or ONE-STEP/ONE-STEP PLUS, however if you do choose to tin-plate, then thorough rinsing (approx. 30 sec. rinse) is recommended).

3. Dispense one drop each of Primer A & B into a mixing well and apply two coats over the prepared surface of metal. Air dry.
OR
Apply 1 coat of ONE-STEP/ONE-STEP PLUS to metal. Air dry thoroughly. Light cure for 10 seconds.

4. Shake Base and Catalyst bottles very well before dispensing. Dispense one drop each of Catalyst and Base onto a mixing pad, and mix with a brush tip.

5. Apply a thin coat of OPAQUER to the metal surface and allow to self cure. Light cure for 5-10 seconds if slumping occurs. An oxygen-inhibited layer will be present on the surface of the OPAQUER once the curing process has completed. This is normal for this material. Composite may be bonded directly to this surface.

6. Proceed with composite layering and finishing.

NOTE
1. If a longer working time is desired, the following is suggested:

a. Mix OPAQUER on the flat mixing pad (instead of in the mixing well) and continue stirring to prolong gelation. Stirring introduces more air inhibition effect.
b. Chill one or both of the OPAQUERS in the refrigerator prior to use. The low temperature will retard the setting reaction.
