Bioclear™ Push-Pull Instruments

The Bioclear™ Push-Pull is a self-expanding, matrix adjusting instrument and is designed to expand and oppose Evolve and Biofit matrices to ensure tight broad contacts. It applies lateral pressure to create a tight contact, plus it expands the matrix buccal-lingually for a broad contact. This is a more modern version of burnishing. Burnishing was a common compromise necessary with metal matrices that lacked appropriate shapes.

The Bioclear™ Adjustable Push-Pull is a posterior instrument that is designed to expand or contract to fit a variety of preparation sizes in order to expand and oppose Evolve and Biofit matrices to ensure tight broad contacts:

• One side is self-adjusting and is used for small cavity preps
• The second side has an adjustable button that expands or contracts the tines to fit a wider range of tooth sizes. The numbers on the side of the instrument give an approximation of where the button should be placed in order to fit that cavity prep width.
• Rounded tips on both sides ensure that the Adjustable Push-Pull does not perforate or dimple the matrix when adjusting.

PLEASE NOTE: We STRONGLY recommend using the Adjustable Push-Pull with the “Spot-weld” technique as this produces best results.
