You are confusing the matrix band which wraps around the tooth, with the clamp, which holds the band in place while the cavity filling hardens.
Naturally the number of matrix bands, which are expendable, would number in the millions.
However, the spring clamps, which are re-usable, would naturally, never approach the numbers you show for the matrix bands.
Please go back to the drawing board and make some new conclusions to jump to.....
...Just saying....do your post right the first time.
