3M Sof-Lex Extra-Thin Contouring and Polishing Discs Kit 2380

Clinical Overview

3M™ Sof-Lex™ Extra-Thin Contouring and Polishing Discs Kit (2380) is a finishing and polishing system designed to deliver smooth, high-gloss restorations with precise control. The extra-thin aluminum-oxide coated discs allow clinicians to access interproximal and hard-to-reach areas while maintaining excellent contouring ability. A color-coded grit sequence simplifies disc selection and ensures a consistent finishing and polishing workflow for composite, ceramic, and glass-ionomer restorations.

Key Benefits

• Extra-thin disc design: Allows precise finishing and polishing in tight interproximal areas and difficult-to-access surfaces.
• Color-coded grit sequence: Simplifies the progression from contouring to final polishing for consistent clinical results.
• Pop-On™ disc technology: Enables fast disc changes to streamline chairside workflow.
• High-luster finishing: Helps produce lifelike, polished restorations with smooth surface texture.
• Flexible contouring action: Discs conform to tooth anatomy, improving control when finishing facial, lingual, and interproximal surfaces.
• Durable RA mandrel: Fracture-resistant metal mandrel provides stable disc attachment and reliable operation.
