BIOCLEAR TwinRing – Sectional Matrix Rings

Bioclear sectional matrix system number 1 over the world
Made in the USA


The Twin Ring is designed to be used in sectional Class II matrix adaptation and can be used with any matrix.

Made of two NiTi wires; The structural design of the Twin Ring causes it to have excellent form memory; it is guaranteed to retain its original shape without deformity, even after hundreds of uses.

The unique design allows the Twin Ring to adapt to a variety of tooth types and shapes. The round cross-section of the ring allows the application of a strong, even tension that:

  • assists in the separation of the teeth
  • creates a strong seal with the matrix without collapsing the matrix into the cavity
  • and doesn’t allow the composite to flow past the gingival margin which eliminates line angle overhangs.



A graph showing the difference between TwinRing yellow and purple separation power and other products’ separation power after 25 uses concludes that the yellow TwinRing has more separation power than any other product.



A Tetra ring

  • Can be used where maximum separation is not required.
