Description

Sectional Contoured Matrix Bands Stainless Steel

Assorted sectional, pre-contoured stainless-steel matrices for reliable Class II contacts and natural proximal contours. 100 pieces across common widths for molars and premolars; ~0.035 mm thin for burnishability with adequate rigidity. Compatible with popular ring/wedge systems.

Key Features

• Pre-contoured, sectional design: expedites emergence profile and tight proximal contacts in posterior composites.

• Thin stainless steel (~0.035 mm): balances adaptability and form memory; comparable systems also offer 0.038 mm options.

• Assorted sizes (posterior): widths for premolar and molar boxes—organized for refill-style use.

• System-agnostic: use with your existing sectional rings and wood/composite wedges. (Examples: Halo™, Cosmedent full-contact, HSI kits.)

• Economical bulk: 100-piece box for clinics, teaching labs, and courses.

Product Description

These posterior sectional matrix bands deliver predictable proximal contacts and contour in Class II composite cases. The pre-anatomical curvature helps reproduce the natural emergence profile while minimizing finishing flash. At ~0.035 mm thickness, the bands adapt with gentle burnishing yet retain shape under ring pressure. The assortment covers typical premolar/molar boxes, so you can pick a width that seats fully gingivally while clearing marginal ridges. Pair with your preferred ring and wedge protocol for a fluid workflow.

What’s in the Box (typical)

• 100 × stainless-steel sectional, contoured matrices

• Mixed widths/sizes for molar and premolar proximals (assortment varies by batch)

Indications & Technique Notes

• Class II MO/DO/MOD posterior composites (premolars & molars)

• Seat the band to full gingival depth, wedge for seal, then place ring for separation/contact.

• Burnish lightly against the adjacent tooth to refine the contact area prior to curing (per your adhesive/composite protocol).

• Remove ring → wedge → band in that order; check contacts and marginal integrity.

FAQs

Do these require a specific ring system?
No. They’re system-agnostic and work with common sectional rings and wedges.

Is 0.035 mm rigid enough?
For most Class II cases, the thickness offers a good adaptability/rigidity balance; some clinicians prefer 0.038 mm for stiffer placement.

Are the bands reusable?
No. Treat as single-use intraoral items per infection-control policy.

What sizes are included?
A practical posterior assortment covering premolar/molar boxes; exact counts per width can vary by batch.
