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.
