Conodent Retainer Ivory with Shields

The Matrix Retainer Ivory with Shield is a surgical-grade operative instrument engineered for Class II restorations, particularly on mandibular (lower jaw) teeth. Combining the classic Ivory matrix tensioning mechanism with an integrated soft-tissue protective shield, it simultaneously stabilizes matrix bands and retracts adjacent oral tissues—such as the tongue, lip, and buccal mucosa. This multi-functional design ensures a dry, highly visible working field, tight cervical seals, and anatomically precise proximal contacts.

Key Clinical Applications

• Class II Restorative Dentistry: Secures and contours matrix bands for MO (Mesial-Occlusal), DO (Distal-Occlusal), and MOD (Mesial-Occlusal-Distal) cavity preparations.

• Mandibular Tissue Management: Provides passive physical deflection of the tongue and cheek during lower arch restorative procedures.

• Overhang Prevention: Applies uniform circumferential pressure to eliminate composite or amalgam overhangs along the gingival margin.

• Isolation Maintenance: Assists in preserving a clean, moisture-controlled field essential for modern adhesive and bonding protocols.

Detailed Functional & Design Features

1. Integrated Soft-Tissue Protective Shield

The side-mounted deflection shield acts as an intraoral physical barrier. It safely retracts the tongue or cheek away from the active preparation site, preventing accidental soft-tissue contact with burs, hand instruments, or etching agents while maintaining clear line-of-sight visibility.

2. Precise Anatomical Matrix Adaptation

The retainer mechanism delivers balanced lateral tension across the matrix band, pressing it firmly against the cervical tooth margins. This reproduces natural interproximal contours, creates tight contact points, and minimizes time spent on post-restorative finishing and subgingival carving.

3. Optimized for Mandibular Anatomy

Specifically tailored to navigate the anatomical constraints of the lower arch, where active lingual muscle movements and heavy salivary flow frequently complicate isolation and matrix placement.

4. Corrosion-Resistant Stainless Steel Construction

Manufactured from biocompatible, heavy-duty surgical stainless steel. The precision threads remain smooth and reliable through continuous mechanical tension, chemical exposure, and high-temperature autoclave cycles.

Cleaning, Maintenance & Sterilization Guidelines

• Decontamination: Rinse immediately post-procedure under cold running water to remove restorative debris, adhesive resin, or biological material.

• Ultrasonic Cleaning: Immerse in an enzymatic bath to clear debris from internal threads and the clamping hinge.

• Autoclaving: Steam sterilize at standard parameters (121°C for 20 minutes or 134°C for 3–5 minutes).

• Inspection: Periodically inspect adjusting threads for smooth action and check the shield wing for alignment.
