Abstract
A V-shaped plastic dental matrix band having an elongate body with first and second ends, a central portion between the first and second ends, and a collar portion on top of the central portion. The plastic dental matrix band tapers in thickness from thick first and second ends to a thin central portion, thereby providing a snug fit and tight contact with the tooth. The thick first and second ends are adapted to provide a bearing surface for the clamping screws of a matrix band retainer. The thickness of the collar portion is the same as that of the first and second ends and tapers from a top of the collar portion to a shared border with the central portion.
