Winged clamps:

The Dam is hinged to the wings of the clamp outside the patient’s mouth. The dental dam, dental dam clamp and frame are all simultaneously positioned into the patient’s mouth. Once applied, the dam is stretched off the wings of the clamp.

Wingless clamps :

First the clamp is positioned intraorally, then the dental dam stretched over the clamp and tooth. Wingless clamps are designated with a „W“ (wingless) for easy identification.
