6 inch X 6 inch=36 sheets
1. Use latex-free dental dam, as it can be used on all patient.
2. Make sure the punch is sharp and well aligned to achieve a clean hole, otherwise the dam sheet will tear when stretched.
Note largest hole for molars and the second-smallest hole for all other teeth being clamped.
These are mainly made of stainless steel and are either winged or wingless. The wingless clamp tends to be put on the tooth first and then the dam sheet is stretched over the clamp in the mouth. The winged clamp tends to be put into the hole in the dental dam first (outside of the mouth) and then positioned onto the tooth altogether.
Over-expanding dental dam clamps may result in their distortion and fracture.
Used to transfer, position, adjust and remove the clamp from the tooth
