Dental Matrix Bands
Definition : Stainless steel bands designed to externally contour and confine dental restorative materials (e.g., resins) during their insertion in teeth. These bands typically consist of 0.015- to 0.05-inch - (0.0381 to 1.27 mm) thick stainless steel ribbons. The bands may be held in place by a mechanical retainer capable of drawing the band snugly around the tooth; the bands may be preformed (e.g., welded) in a loop that seals tightly around the tooth when used with a moisture absorbing wedge without using a retainer (i.e., retainerless matrix). Dedicated matrix bands are available for specific teeth (e.g., primary tooth, premolar, molar); matrix bands are also available in rolls intended for contouring segments to the appropriate length and shape for the characteristics of the tooth being restored as well as the position of the adjacent teeth.
