Dental Polishing Mandrel Kit - 1 Mandrel + 40 Thin Finishing & Polishing Discs (14 mm)

This dental finishing and polishing kit includes one reusable metal mandrel and 40 ultra-thin discs designed for the sequential processing of composite, ceramic, and glass-ionomer restorations. The discs have a diameter of 14 mm and are color-coded according to their purpose: blue for coarse finishing, green for contouring, yellow for fine finishing, and white for final polishing. Each color corresponds to a specific operating speed to ensure controlled material removal and gradual surface refinement. The ultra-thin profile of the discs is engineered to facilitate access to interproximal areas and curved surfaces while maintaining stability during rotation. Their cutting performance supports a progressive workflow without abrupt transitions between stages. The color-coded system helps ensure correct disc selection throughout the procedure. The included metal mandrel is compatible with standard sterilization protocols and can be disinfected either by steam autoclave at 132°C for 20 minutes or through immersion in 6% hydrogen peroxide solution. This allows consistent reuse without compromising structural integrity. All discs are single-use only, maintaining hygiene standards and ensuring unchanged performance during each procedure. The recommended rotation speeds are 10,000 rpm for the blue and green discs and 30,000 rpm for the yellow and white discs. Working time per disc ranges between 15 and 20 seconds, allowing controlled and predictable progression. For the initial coarse finishing step, the duration can vary as needed. Using the discs in the correct sequence is essential to achieve a uniform and well-structured workflow. The set is suitable for a wide range of dental applications, including finishing and polishing composite restorations, adjusting surfaces on ceramic materials, and refining restorations based on glass-ionomer formulations. The discs can be used on vestibular or occlusal surfaces as well as in areas where access is limited due to their thin design. Safety instructions specify not to exceed 30,000 rpm to avoid disc failure or mandrel damage. The mandrel should not be operated without a disc attached, and adherence to the correct usage order ensures balanced surface preparation. The package includes one sterilizable metal mandrel and 40 assorted ultra-thin discs distributed across four colors: blue, green, yellow, and white, ten pieces of each. This kit provides a complete and structured solution for sequential dental finishing, contouring, and polishing procedures, offering precise control and consistent operational performance.
