3M Filtek One Bulk Fill Restorative Syringe 4g Shade A2 4870A2

Clinical Overview

3M™ Filtek™ One Bulk Fill Restorative Syringe (4 g) is a light-cured bulk-fill nanocomposite restorative designed to simplify restorative procedures while maintaining strength and aesthetics. The material incorporates advanced nanofiller technology and stress-relieving monomers that allow clinicians to place restorations in a single increment with curing depths of up to approximately 5 mm. The syringe delivery format allows precise placement, adaptation, and sculpting, supporting efficient restorative workflows in both posterior and selected anterior applications.

Key Benefits

• Bulk-fill efficiency: Allows single-increment placement with curing depths up to about 5 mm, reducing layering steps.
• Low polymerization stress: Advanced monomer technology helps reduce shrinkage stress and improve restoration integrity.
• TRUE nanotechnology: Nanofiller system provides excellent wear resistance and long-lasting polish retention.
• Improved esthetics: Optical properties help restorations blend naturally with surrounding tooth structure.
• Excellent handling: Smooth consistency allows precise sculpting and adaptation to cavity walls.
• Radiopaque formulation: Clearly visible on radiographs for reliable post-treatment evaluation.
