Description
Four D Biodam Latex Dental Dam is a natural rubber latex dam made in the United Kingdom by Four D Rubber, the manufacturer behind the Isodam line. The low protein, low powder sheet carries the high tear resistance printed on its retail box, so it stands up to clamping and retraction. One latex dam family covers two sheet sizes, three gauges and two colors, which keeps operatory stocking simple.
- High Tear Resistance – Four D Rubber prints high tear resistance, low powder and low protein on the Biodam retail box.
- Two Sheet Sizes – The 5 by 5 inch sheet comes 52 to a box and the 6 by 6 inch sheet 36 to a box.
- Three Gauges, Two Colors – Thin, medium and heavy sheets in blue or green cover the full placement range.
- Made in the United Kingdom – Four D Rubber manufactures its dental dams at its United Kingdom facility.
Natural Latex Isolation From the Isodam Manufacturer
Biodam is Four D Rubber’s latex dental dam for everyday isolation in restorative and endodontic work. The natural latex is low in protein and low in powder, two properties the manufacturer builds into the sheet to keep the working field clean. Published test data for the material shows a tensile strength of 20.0 MPa and an elongation at break of 800 percent, so the sheet stretches over clamps without giving up. The 5 by 5 inch sheet comes 52 to a box for smaller frames, and the 6 by 6 inch sheet comes 36 to a box for standard adult setups. Thin, medium and heavy gauges in blue or green let each operatory standardize on the sheet it prefers.
Features and Benefits
Material Performance
- 70 N/mm Tear Strength: The published tear strength helps the sheet resist nicking at punch holes and clamp edges during placement.
- 800 Percent Elongation: The sheet stretches to eight times its length before breaking, so it passes over tight contacts and clamp wings.
Cleaner Working Field
- Low Protein Latex: Four D Rubber formulates the sheet as a low protein latex dam, a point its own promotional literature leads with.
- Low Powder Finish: Low powder on the sheet means less loose powder around the preparation.
Size, Gauge and Color Choice
- Every Combination Stocked: Each gauge comes in both sizes and both colors, so the exact sheet a clinician wants is on the shelf.
- Gauge Range For Every Case: Thin sheets place easily, medium covers daily work and heavy gives firmer tissue retraction.
