In the heavy-duty restorative landscape of the Egyptian dental market, Amalgam polishing remains a vital step within the broader process of Finishing & Polishing to ensure the clinical longevity of posterior restorations. While high-copper alloys have improved the durability of silver fillings, the final surface texture ultimately dictates the material’s resistance to corrosion and plaque accumulation. Professional amalgam polishing transforms a dull, carved surface into a mirror-like finish, minimizing Gamma-2 phase vulnerabilities and reducing the risk of marginal breakdown.
At MedSTA, we provide specialized amalgam polishing kits—including silicone-carbide points and cups—designed to help local practitioners achieve a smooth, biocompatible surface that prevents localized gingival irritation and the metallic taste often associated with unpolished restorations.
How to Choose the Right Amalgam polishing Tools for Your Practice
Sequential Grit System: Always choose Amalgam polishing tools that follow the traditional "Brownie, Greenie, and Super-greenie" sequence. This systematic progression from coarse (brown) to high-luster (yellow-banded green) ensures you remove surface irregularities before achieving a final high-shine finish.
24-Hour Set Requirement: Ensure you select Amalgam polishing kits intended for use after the material has fully crystallized. Clinical standards in the local market dictate that polishing should occur at least 24 hours after placement to avoid disturbing the "green" amalgam and compromising the marginal seal.
Heat Management Design: Prioritize Amalgam polishing rubbers that are engineered for low heat generation. Because amalgam is a high-conductivity metal, choosing tools that dissipate heat is essential to prevent pulpal damage and the release of mercury vapor during the polishing process.
Shank Specification (RA/Latch Type): Most Amalgam polishing points are used with a slow-speed contra-angle. Verify that the tools have a high-quality Right Angle (RA) shank that fits securely into your handpiece, ensuring vibration-free operation and maximum tactile control.
Shape Variety (Points vs. Cups): Opt for a kit that includes both points and cups. Points are necessary for the Amalgam polishing of deep occlusal pits and fissures, while cups are superior for smoothing the large, convex surfaces of molar cusps and marginal ridges.
