For use in sectional Class II matrix adaptation, the Bioclear™ Twin Ring adapts to a variety of tooth shapes, creates a strong and even tension, has excellent form memory and can be used with any matrix.

The Twin Ring Universal is a major advancement in design and function that will be a welcome upgrade to your Class II composite procedure. The unique design allows the Twin Ring Universal to adapt to a variety of tooth types and shapes, even short molars, short premolars, primary molars, and on top of rubber dam clamps. Other features and benefits include:

  • Unique design allows for very strong separation without hand strain
  • Creates a strong seal and doesn't allow the composite to flow past the gingival margin thus eliminating line angle overhangs
  • Excellent form memory; it is guaranteed to retain its original shape without warping, even after hundreds of uses
  • Adapts and adheres to a variety of tooth types and shapes
  • Can be used with any matrix
