What are matrix bands?
Matrix bands are one component of the matrix system, which is comprised of the following: sectional matrix retainers, wedges, adjacent tooth guards, instruments and matrix bands. Early sectional matrix retainers began with a simple all-metal half-ring that is placed via rubber dam clamp on minimally contoured stainless-steel sectional matrix bands. The thin metal tines or tips created decent contacts – an improvement over the Tofflemire system. Second-generation matrix rings added plastic tips, creating more surface area for contact creation. Then came the more robust nickel titanium retainer rings. Today’s clip design is reportedly more durable and allows the retainer clip to double as a rubber dam clamp.
How much does a sectional matrix band cost?
Remind customers that sometimes spending a bit more upfront will yield a greater value down the road. Sectional matrix bands can range from $0.03 to $1 per band. Cheaper bands generally are not coated. They have minimal contouring and no placement tabs. In contrast, more expensive bands offer non-stick coating, an assortment of placement tabs and pronounced contouring. Dentists who use cheaper bands must spend more time burnishing, or using an instrument to create contour in the band. And because these bands usually are non-coated, bonding agents stick to them, making them more difficult to remove. These features reportedly translate into a more refined, plug-and-play device said to save time and money in the long run.
