Dental Rubber Dam Clamp – For bicuspids, especially for sub gingival cavities with deeply festooned serrated beaks. – NES-3290

Fig. 1AT
The NES-3290 (Fig. 1AT) steps up from the standard bicuspid clamp with deeply festooned serrated beaks, purpose-built for sub-gingival cavities where a shallower beak wouldn’t reach the necessary margin. That deeper festoon lets the clamp grip further beneath the gumline than the standard bicuspid pattern.
What makes this deeper festoon useful:
Reaches sub-gingival cavity margins that shallower beaks can’t access
Serrated edge adds extra grip security during longer procedures
Purpose-built for bicuspid anatomy specifically
Fully autoclavable stainless steel construction
Sub-gingival access is a routine challenge in restorative dentistry, particularly when decay or a fracture extends below the visible gumline. A clamp shaped specifically for that depth removes the need to improvise with a shallower, less appropriate beak.
Among the maxillofacial surgery instruments used in restorative isolation work, this deeper-festoon bicuspid clamp fills a specific niche alongside the standard bicuspid pattern, giving practitioners the right tool depending on how far below the gumline the cavity extends.
Built from stainless steel, this clamp withstands repeated sterilization and daily clinical handling, holding its deep-festoon fit reliably over time.
