Description
SMS Instrument Matrix Squiveland 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 Squiveland 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.
