PRIMA Sectional Metal Dental Matrices, Stainless Steel, M/L Sizes, 50 pieces

PRIMA sectional metal dental matrices are professional-grade instruments designed for precise restoration of natural tooth anatomy. Made from high-quality stainless steel, these matrices provide durability, corrosion resistance, and stable performance during restorative procedures.

Technical specifications:
• Material: Stainless steel
• Sizes: M - 5.2 mm / L - 6.4 mm
• Thickness: 3.5 mm
• Pack: 50 pieces
• Silicone-tipped ring ends for secure and precise adaptation

Functionality and principle of use:
These matrices act as a mechanical device to support accurate anatomical restoration using restorative materials. They are positioned on the proximal surface of the tooth and stabilized with a ring and wedge. For MOD (mesio-occluso-distal) cavities, surfaces are restored sequentially to ensure precision. Silicone tips on the rings provide uniform adaptation, prevent slippage, and maintain consistent contact points.

Instructions for use:
• Select the appropriate matrix size for the cavity
• Place the matrix on the proximal surface and secure it with the ring and wedge
• For extended cavities, restore surfaces individually for accurate contouring
• Remove the matrix after restoration is complete
• Clean immediately before and after use to prevent residue hardening

Maintenance and sterilization:
• Clean with water and enzymatic detergent
• Steam sterilization only, in CE/FDA-approved sterilization pouches
• Store the product in the sterilization pouch until use
• Ring and silicone tips must be sterilized separately
• Sterilization may slightly change color without affecting performance

Safety instructions:
• Professional use only
• Avoid use if allergic to any components
• Prevent over-expansion and improper ring handling
• Protect soft tissues and isolate the operative field
• Ensure correct positioning in the clamp

These matrices provide precision, stability, and consistent anatomical contouring in restorative dental procedures, supporting professional-quality results.
