Nitin Sectional Matrix Halka

*** Product information “NiTin Molar Rings” Made from drawn Nitinol wire, NiTin rings last longer.
*** You want your separator ring to separate the teeth the same way after 100 uses as it did when it was brand new.
*** Drawn-wire Nitinol does the job better than regular nickel-titanium or stainless steel.
*** The matrix ring refill includes 2 rings.
