For use with large and extensive anterior cases Tokuyama offers OMNICHROMA BLOCKER a supplementary material to be used in conjunction with OMNICHROMA for the direct restoration of extensive Class III and IV cavities.

OMNICHROMA BLOCKER can be used as a lingual layer to prevent shade-matching interference in these cases. OMNICHROMA BLOCKER can also be used to mask slight staining or to reconstruct a highly opaque tooth.
