  • Patent number: 4202103
    Abstract: A matrix band guide for use in simultaneously applying a matrix band to a plurality of teeth. The guide is a flexible elongated member having a plurality of slots. The elongated member is of sufficient length and of sufficient width to allow placement of the guide against the teeth and to guide the matrix band around the teeth. The slots are of a width, height and spacing sufficient to permit the looping of the matrix band through the slots to form a plurality of loops for binding engagement with the teeth. When the matrix band is drawn into binding engagement with the teeth, the elongated member and the matrix band substantially conform to the taper and curvature of the teeth.The guide, may have a mounting means for mounting the elongated member to a conventional matrix retainer in such a manner that the matrix band can be drawn into binding engagement with the teeth by the conventional matrix retainer.The elongated member may also be shaped to substantially conform to the alignment of the teeth.
