Halo matrix bands are made of ultra-thin 0.038 mm stainless steel that is anatomically shaped to match the natural form of the tooth. The curve at the marginal ridge creates an ideal occlusal space to help ensure anatomically accurate restorations and reduce the time required for modeling and finishing composite restorations. Available in Original and Firm, the Original bands allow for greater adaptability, while the Firm bands are ideal for reduced interproximal spaces. The Firm matrix bands are available with or without a special non-stick coating that is color-coded according to size to assist you in selecting the correct band.
