SMS Instrument Matrix Siqveland Clamp is a self-adjusting, simple to operate, band retainer, suitable for use on all teeth. For best results and to avoid gingival ledges and overhangs, the wedging of matrix bands is always recommended. The Siqveland Clamp was invented to minimize the problems encountered with the Wagner matrix. A Swivel lock is incorporated into this retainer that permits a withdrawal of the band securely at the gingival third of the tooth.

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.
