MATRIX -BANDS

Mylar Matrix Bands are thin, solvent-resistant polyester strips used across Egyptian dental clinics to build a convex, natural-looking interproximal surface on anterior composite restorations. Unlike ordinary celluloid, Mylar won't stretch, curl, tear, or soften on contact with bonding solvents, so it holds its shape reliably through the whole restorative sequence.

Clinical Uses

• Shaping the interproximal (mesial/distal) contour of anterior composite fillings
• Class III and Class IV restorations where a convex, anatomically correct contact is critical
• Diastema closures and composite veneers where strip rigidity affects the final contour
• Teaching labs where strips need to survive repeated student handling without tearing

Key Features

• Solvent-Resistant – Unaffected by bonding agents and etchants during placement
• High Tensile Strength – Will not stretch, curl, or break under normal clinical use
• Smooth Finished Edges – Comfortable against gingival tissue on insertion and removal
• Consistent Contour Control – Helps recreate a natural convex interproximal surface

Specifications

How to Use

1. Separate the contact with a wedge prior to placement
2. Position the Mylar strip interproximally, covering the full cavity margin
3. Pack composite through the strip and pull it firmly to define a convex contact point
4. Light-cure while holding tension on the strip, then release and cure again if needed
5. Remove the strip and refine the contact with finishing strips

Why Buy From MedSTA

• Consistent, tear-resistant strips that hold up in high-volume clinics and student practicals
• Fast delivery across Cairo and nationwide Egypt
• Easy to combine with wedges and composite from the same order

FAQ

How is Mylar different from celluloid matrix strips?
Mylar (polyester) is more solvent- and stain-resistant and holds tension better than celluloid, making it a common choice when contour control matters most.

Can I light-cure composite through this strip?
Yes, Mylar strips are used the same way as celluloid strips — position, pack composite, and cure directly through the strip.

Are these strips reusable between patients?
No, they should be used once per restoration and discarded for hygiene and predictable results.

Do these strips work for diastema closure?
Yes, their rigidity and convex-contour control make them a popular choice for diastema closures and anterior composite veneers.
