About Tofflemire Matrix Retainers
A Tofflemire retainer holds a thin metal matrix band around a tooth so that a filling can be packed against it and shaped. The band loops through the slotted head; one knob locks the band in the retainer and the other tightens or loosens the loop around the tooth. It is one of the most familiar instruments on a restorative tray.
How it works
- Thread the band into the slotted head in the direction the cavity needs.
- Turn the locking knob to secure the band.
- Place the loop over the tooth and turn the adjusting knob to tighten it.
- After packing, loosen the band and remove the retainer before taking the band out.
Choosing bands
Matrix bands are separate and come in different widths and shapes. Check that the bands you use fit the slotted head on a sample retainer before ordering in quantity.
Tofflemire or sectional matrix?
A Tofflemire band wraps around the whole tooth. A sectional matrix covers one side and is held with a ring placed with sectional matrix ring forceps.
Ordering
- Order by quantity; each unit is one retainer.
- Evaluation samples of 1–3 pieces per pattern are available.
Care
Check that the screw turns smoothly and the head slots are not damaged. Follow the supplied processing instructions and your facility's validated protocol.
