Dental Instruments
SMS Instrument Tofflemire Matrix Bands are pre-contoured, thin stainless steel bands that are easy to mold and burnish for proximal contact. Band is carefully smooth (burr-free) edges that keep your patient comfortable and reduce risk of gingival trauma. Available in a variety of sizes.
Matrix band is used when doing interproximal restorations. Simply put, its purpose is to keep composite from coming in contact with the adjacent teeth. It forms the interproximal wall. It has concave surface (upward) & one convex (downward). The conxity of matrix band should put on the occluscal surface.
Used to support the wall.
To replace the missing proximal walls of cavity preparation of condensation of restorative material.

Matrix Retainer
A Dental Matrix Retainer is mechanical used to secure the ends of a matrix band around a tooth. The band provides a substitute wall where a part of the tooth is missing and helps to compact a restoration into a prepared tooth cavity after the carious lesion has been removed. Usually by engaging the ends of the matrix band and drawing the band tight. When a restoration involves an interproximal surface, it is not possible to achieve a properly adapted restoration without a matrix band. A matrix band creates a temporary interproximal surface, and, when appropriate, a matrix retainer secures the matrix band in place.
Function of matrix
- To confine restorative material while it is hardening.
- To established optimal contacts and contours for the restoration.
- To prevent gingival overhangs off restoration.
- To provide acceptable surface texture for restoration.
