NES-3374

Every rubber dam procedure starts with a single, precise decision: where exactly does the hole go? The Ainsworth pattern has been answering that question for generations of dental practitioners, and the NES-3374 brings this trusted punch design into modern clinical practice, ready to earn its place as one of the most frequently reached-for instruments on the isolation tray.
Punching accurate holes in dam material is deceptively difficult to do well by hand. Too small a perforation and the dam tears trying to stretch over the tooth; too large and it won’t seal snugly enough to keep the field dry. The Ainsworth punch solves this with a rotating wheel of graduated hole sizes, letting practitioners select the exact diameter needed for a given tooth, whether that’s a narrow incisor or a broader molar, without switching instruments mid-setup.
That graduated wheel is really the heart of what makes this pattern so enduring. Rather than a single fixed punch size forcing compromises across different tooth types, the Ainsworth design adapts hole-by-hole, giving practitioners consistent, clean perforations across an entire arch in one continuous setup sequence.
Among the maxillofacial surgery instruments that support rubber dam isolation, a well-calibrated punch like this one quietly determines how smoothly the rest of the procedure goes. A ragged or mismatched hole creates problems that ripple through every later step, from clamp placement to maintaining a dry field.
Built from stainless steel, this punch withstands the mechanical stress of repeated perforation work and standard sterilization cycles, holding its precision hole sizing reliably appointment after appointment.
