Wedges

Description

Wedges are small, tapered interproximal aids used with matrix systems to shape restorations and seal the gingival margin. Inserted below the contact, a wedge gently separates adjacent teeth to compensate for matrix thickness and prevents overhangs. These color-coded polymer wedges adapt to the papilla, compress slightly for a tight seal, and help deliver proper contour and contact in Class II composites and other posterior restorations.

Key features and benefits:

• Anatomical, triangular profile with a concave side for close gingival adaptation.

• Gentle tooth separation that creates tight, natural contacts after curing.

• Smooth, non-splintering polymer that seats comfortably and resists collapse.

• Color-coded sizes for quick selection and predictable fit.

• Rounded edges to protect papilla and soft tissues.

• Available in translucent options that allow light transmission for cure-through and in radiopaque options for visibility on X-rays.

Typical uses:

• Class II composite restorations with sectional or circumferential matrices.

• Removing excess resin cement around inlays, onlays, and crowns while protecting tissue.

• Refining embrasures and emergence profiles during finishing and polishing.

How it compares:

• Plastic wedges offer shape memory and translucency; wooden wedges provide strong compression but may splinter and do not transmit light.

• Rings provide separation; wedges create the gingival seal. Most clinicians use them together for reliable contacts and margins.

Handling tips:

• Pre-wedge when possible to open the contact and control moisture.

• Seat from the wider embrasure, press apically to seal the margin, and verify matrix adaptation before curing.

• Dispose after single use as part of standard infection-control practices.
