The Dental Rubber Dam Clamp No. W7 is a foundational posterior isolation instrument engineered for efficient modern dental workflows. Crafted from surgical-grade stainless steel, this clamp features a wingless configuration (‘W’ prefix) and flat jaws, making it the clinical standard for isolating lower molars without disrupting the placement of adjacent restorative matrices.
Key Features and Design
-
Wingless Configuration: Built without lateral wings to offer a more compact profile. This allows the practitioner to precisely seat the clamp on the tooth cervix first, then stretch the rubber dam sheet over the bow and jaws.
-
Flat Mandibular Jaws: Specially paired with a flat, paired jaw contour that adapts perfectly to the unique anatomy of mandibular molars, ensuring solid, non-rocking retention.
-
Premium Stainless Steel: Forged to maintain excellent spring tensile memory and maximum resistance against structural corrosion. Fully compatible with standard high-temperature autoclave sterilization cycles.
