Packable Bulk Fill Composite, 4mm
VOCO x-tra fil is a posterior bulk fill restorative — a nano-hybrid packable bulk-fill composite resin for direct Class I/II restorations. As a 4mm bulk fill composite, it places in one increment up to 4 mm — no layering needed. This packable bulk fill composite cures fast: 10 seconds for 4 mm with a high-power LED. Nano-hybrid filler delivers high wear resistance for posterior stress-bearing areas.
Low shrinkage stress and a universal shade make this posterior bulk fill restorative safe, fast, and simple for everyday posterior work.
