Designed for the unique demands of dental porcelains
Sigma Polishers are engineered specifically for finishing and polishing feldspathic porcelain, giving technicians the right balance of control and efficiency. Their specialized design makes it possible to achieve smooth adjustments and a natural, high-gloss finish with only a light touch. Consistent performance across shapes ensures dependable results on every porcelain restoration.
What makes Sigma Polishers different?
Unlike general-purpose polishers, Sigma is tailored specifically for porcelain’s unique properties. Their carefully balanced construction delivers controlled material removal with minimal pressure, reducing the risk of chipping or altering fine anatomy. The result is a smoother workflow where technicians can contour, blend, and finish porcelain restorations with confidence.
