Description

An absolute standard in operative dentistry, this premium Universal Tofflemire Matrix Retainer is engineered to secure and stabilize matrix bands for flawless Class II restoration anatomies. The universal mechanical design allows clinicians to easily adapt, tighten, and lock thin stainless steel or plastic matrix bands around posterior teeth, effectively replacing missing wall structures during amalgam, composite, or glass ionomer packing. By providing rigid lateral support, this retainer ensures that restorative materials can be densely condensed to form tight, anatomically correct interproximal contact points and smooth marginal borders.

The retainer features a highly polished, smooth-turning adjustment screw and locking nut that offer micro-precise tension control, preventing the matrix band from slipping or stretching during material placement. Its versatile slotted guide channels at the working tip allow the matrix band to emerge straight, left, or right, providing full multi-quadrant accessibility in both the upper and lower arches. Forged from high-tensile, medical-grade surgical stainless steel, this robust instrument is built to withstand heavy clinical clamping pressures and maintain its smooth mechanical thread alignment through thousands of procedures.

Key Features & Technical Specifications

• Universal Multi-Angle Alignment: Designed with a triple-slotted guide head that allows the matrix band to be directed left, right, or straight for maximum quadrant versatility.
• Micro-Threaded Tension Adjustment: Equipped with a precision-machined inner screw mechanism that allows for ultra-fine tightening of the matrix band around the tooth perimeter.
• Anatomical Contact Restorations: Vital for establishing proper proximal contours, preventing material overhangs, and recreating tight interdental contacts in posterior teeth.
• Ergonomic Threaded Handles: Features knurled control knobs that provide a non-slip, positive grip for effortless one-handed tightening and loosening maneuvers.
• Deformation-Resistant Construction: Forged from high-purity surgical steel to prevent the guide arms or internal threads from stripping under high tension.
• 100% Autoclavable: Fully engineered to endure repeated high-temperature autoclave sterilization and ultrasonic cleaning cycles without jamming or mechanical wear.
