(OMNICHROMA BLOCKER) is indicated for preventing shade-matching interference in Class IV restorations, Masking dark dentition and dentin. 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 obstruction and mask staining.

Treatment:

Diagnostic Test: single-shade universal resin composite (omnichroma) with blocker( omnichroma blocker)

single shade universal resin composite(GC solare sculpt) with chameleon effect

Active Comparator group

Description:

One-shade universal resin composite (GC solare sculpt) gives very natural appearance, High gloss retention over time, time saving regarding to layering technique, wide shade matching range (chameleon effect) and delivering lifelike aesthetic restorations. These features can be offered by supra-nano spherical filler which have controlled refractive index, records excellent esthetic properties in small and medium class IV restorations.
