Twin Ring

The Twin Ring is designed for use in sectional Class II matrix adaptation and can be used with any matrix. The unique design allows the Twin Ring to adapt to a variety of tooth types and shapes. The geometry of the ring causes it to apply 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.
