The present invention relates to a dental matrix band used during tooth restoration procedures. The matrix bands have a smooth interior side which is placed in contact with the tooth requiring restoration. The exterior side a frictional engagement surface which is at least a portion of its surface that is configured to provide increased friction. Such a matrix band is placed around a tooth to be restored with the frictional engagement surface facing the embrasure or space between the teeth. A dental wedge can then be inserted into the embrasure against the frictional engagement surface to hold the dental matrix band stationary with respect to the tooth being restored. The frictional engagement surface is sufficiently rough that dental wedges are much less likely to slip out of an embrasure once positioned against the frictional engagement surface, thereby ensuring that a matrix band will be securely held in place by a dental wedge to enable the practioner to confidently proceed with the restoration. The matrix bands may be formed from opaque materials such as stainless steel or from materials which are at least translucent.

[ What is claimed and desired to be secured by United States Patent is:] [1.]1. A matrix band comprising:a flexible strip having a first end opposite a second end and a top edge opposite a bottom edge,wherein the flexible strip has an elongated and slightly curved configuration such that when the ends are joined together the matrix band has a midsection which is scooped to enable the matrix band to anatomically conform to a tooth when positioned around a tooth requiring restoration,the flexible strip having opposing sides including an interior side and an exterior side,wherein the interior side is smooth for contact with the surfaces of a tooth requiring restoration and for contact with the restoration,wherein the exterior side has at least a portion of its surface configured as a frictional engagement surface to provide frictional engagement with a dental wedge pushed against the frictional engagement surface,wherein the frictional engagement surface of the exterior side is significantly rougher and more abrasive than the interior side.
