The plastic clear band for dental restoration is a dental matrix band having an elongate body with first and second ends and at least one light transmissive portion midway between the first and second ends. The first and second ends have a thickness greater than the light transmissive portion, the band tapering in thickness from a thin central portion to the thick first and second ends. The thick first and second ends are adapted to provide a bearing surface for the clamping screws of a matrix band retainer, while the thin central portion provides a snug fit and tight contact with the tooth. The band is made from biocompatible plastic, and has an inverted V-shape or chevron configuration when viewed from the front.
