    Abstract: 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.

  • Patent number: 8425228
    Abstract: A dental wedge for use in the inter-proximal space between adjacent teeth is described. The wedge comprises a taper section ending at a tip, and a body section extending to the tapering section at one end. The body section has an inverted V-shaped cross-section, flexing of the sides of the V-shape allows the wedge to adapt to various contours of the inter-proximal space. The mid-portion of the body section is narrower than at least a portion of the wedge either end of the mid-portion.
