Saddle Contoured Metal Matrices large1.312 12 pcs № 4 (0.035mm) -TOR V M-Russia

From Alex Dent's catalogue

There are matrices of 4 shapes: shape 1 – standard, shape 2 – with adjustable central part, shape 3 – with enlarged sub-gingival ledge, shape 4 – with narrowed edges. The height of the tubes at the edges of the matrices of shape 4 is 2 times less than that of matrices of shapes 1 – 3. The narrow edges of the shape 4 matrix do not rest on the gum, that allows the matrix to be placed on a low crown and moved around the tooth. All matrices are available of two thicknesses – 0,050 mm and 0,035 mm. Specify, please, the necessary type, e.g., 1.312 – 0,035 mm, otherwise you’ ll receive matrices of the first type, i.e. 0,050 mm.
