OMNICHROMA BLOCKER

OMNICHROMA BLOCKER is indicated for:

  • Preventing shade-matching interference in large Class III and Class IV restorations
  • Masking amalgam staining
  • Masking dark dentition and dentin
  • Reconstructing a highly opaque tooth
OMNICHROMA BLOCKER is a supplementary product to OMNICHROMA. In large Class III and IV cases, OMNICHROMA may experience shade-matching interference due to a lack of surrounding tooth structure and/or dentition. OMNICHROMA BLOCKER is a supplementary material that can be used in conjunction with OMNICHROMA as a lingual layer to prevent shade-matching interference in these cases. OMNICHROMA BLOCKER can also be used to mask staining, or to reconstruct a highly opaque tooth.
How OMNICHROMA works is by manipulating light, and reflecting the shade the composite has been bonded to, through it’s uniform spherical fillers. In cases where there is a lack of tooth structure to bond to, BLOCKER works as a supplementary product to provide a lingual wall to the restoration, prevent shade-match interference, and mask staining or access holes.
No Blocker Used
Note the OMNICHROMA attempting to shade match with the shadows of the mouth. This is due to OMNICHROMA not being bonded to a surface. The fillers cannot reflect the shade-match back to our eyes.
Blocker Used
The light penetrates OMNICHROMA but stops at the lingual wall of BLOCKER, which provides a surface for OMNICHROMA to shade-match to.
Blocker thickness depends on the case. The standard for Class IIIs and Class IVs is 0.5 mm. When the tooth is more opaque, layer Blocker slightly thicker. When the tooth is more translucent, thin the Blocker out.
Once BLOCKER is in place, OMNICHROMA will continue to shade-match as if it was bonded to natural enamel.
Procedure Tip: Use a thicker layer of BLOCKER for high brightness/opaque cases and a thinner layer for low brightness/transparent cases.

PROCEDURE VIDEO

POSTERIOR BLOCKER PROCEDURE GUIDE

Use BLOCKER before filling with OMNICHROMA for masking discolored teeth or metals. OMNICHROMA will assimilate to the color of BLOCKER, or the color of the masking material used.

Procedure Tip: BLOCKER is great for access holes

Preparation and Bonding

Prepare the cavity and add a bevel to help eliminate margin visibility and aid in shade matching. Apply bonding agent.

Applying BLOCKER

Apply Blocker as a base layer to mask discoloration or access holes. Thickness of the layer can vary, but 1 mm is illustrated as a guide. Light cure.

Applying OMNICHROMA

Apply OMNICHROMA in 2mm increments.

Light curing

Light cure according to curing light IFU.

Finishing and Polishing

Finish and polish the restoration.

ANTERIOR BLOCKER PROCEDURE GUIDE

Use BLOCKER before filling with OMNICHROMA for direct restoration of extensive Class III and IV cavities with limited or no tooth structure. This prevents the restoration from appearing dark due to visible light transmission from the labial to the lingual.

Procedure Tip: To enhance both esthetics and retention, add bevels to the enamel margins of anterior preparations.

Preparation and Bonding

Prepare the cavity and add a bevel to help eliminate margin visibility and aid in shade matching. Apply bonding agent.

Applying BLOCKER

Apply BLOCKER as a lingual layer. Thickness of the lingual layer can vary, but 0.5 mm is illustrated as a guide. Light cure.

Applying BLOCKER

Apply BLOCKER as a lingual layer. Thickness of the lingual layer can vary, but 0.5 mm is illustrated as a guide. Light cure.

Applying OMNICHROMA

Apply OMNICHROMA as a secondary layer. Light cure.

Finishing and Polishing

Finish and polish the restoration.
