Copper Band highly malleable, thin metal rings used in restorative dentistry as a customized matrix system. They are designed to fit snugly around teeth to provide a rigid barrier for isolating subgingival areas, allowing for precise placement of core build-up materials or deep margin elevation.
Superior Adaptation: Due to high malleability, copper bands can be shaped to the exact contour of a tooth, ensuring a tight seal against saliva, blood, and gingival fluids.
Deep Margin Elevation: They are used to elevate subgingival margins, avoiding the need for surgical crown lengthening.
Stability for Core Build-up: Acts as a rigid, custom-fit, temporary matrix for holding composite resin during buildup on severely damaged teeth.
Versatility: Can be used to take impressions, especially in cases where gingival hemorrhage is difficult to control.
Material Properties: They are sterilizable, cost-effective, and can be cut to fit.
