The present invention pertains to a device for retaining a matrix band about at least a portion of a periphery of a tooth to be treated, the device comprising: a first lug to fit on one side of a proximal contact between two teeth; a second lug to fit on the other side of said proximal contact, and a resilient body member connecting between the first lug and said second lug. The body member applies a restorative or clamping force biasing the lugs together against opposed sides of the proximal contact and holds the lugs such that they must be separated to fit over the proximal contact. The first and second lugs are pivotally coupled to the resilient body member to allow the resilient body member to rotate relative to the lugs while providing the clamping force biasing the lugs together.

A dental matrix band includes a band having a first end and a second end. The band is folded over with the first end and second end generally aligned. A portion of the band adjacent the first and second ends form opposed facing band portions in contact with one another, and another portion of the band forming a looped band forming a circumference. A first or stationary toggle is secured to the band at the first and second ends with the first toggle stationary with respect to the band. A second or movable toggle is formed over the band and is capable of sliding over the opposed facing band portions in contact with one another, whereby sliding of the movable toggle away from the first and second ends causes the circumference of the looped band to reduce in size.
