How to choose
- For Class II cavities, the manufacturers indicate Palodent V3 sectional matrices and Adapt SuperCap circumferential matrices. Stainless steel sectional matrices are held with a ring, and contoured saddle matrices with a spring.
- Pro-Matrix and Omni-Matrix have an integrated retainer, so no placement instruments are needed; the band is tightened with its own knob or handle.
- According to the product sheets, Ivory, Pony and Mylar bands and matrices with an integrated retainer are single-use. The Tofflemire and Ivory retainers are stainless steel, and the single ring for saddle matrices is autoclavable; for contoured metal matrices, the product sheet states whether they can be sterilized.
- Wedges hold the matrix at the cervical margin. Palodent V3 anatomical wedges, in small, medium and large (100 pcs), have wings that compress on insertion and then expand, and a hollow section that allows a second wedge from the opposite side. Wooden wedges, Poly wedges with a ring and elastic silicone wedges are under wedges.
The Small clamp helps place the rings.
