ABSTRACT:
A dental instrument for assisting in the placement of a dental matrix band around a tooth to be repaired and the associated gingival margin of the repair. The dental matrix includes an elongated slender handle having a thin guide blade disposed from at least one end of the handle. The guide blade is adapted to be fitted between the matrix band and the tooth to be repaired to facilitate positioning of the matrix band over the gingival shoulder of the repair, then progressively around the tooth. The guide blade is preferrably tapered toward its distal end, having a generally curved transverse section to mate against the side of the tooth. The guide blade may also include matrix band engaging means for providing positive connection between the matrix band and the matrix band during manipulation of the guide blade toward the patient's gums and the base of the tooth for enhanced positive and quick disposition of the matrix band.
