What type of clamp has extra extensions to help retain the dental dam?

The type of clamp that has extra extensions designed to help retain the dental dam is known as a winged clamp. These wings provide additional stability and ease of placement by allowing the dentist to secure the dental dam more effectively during procedures. The extensions facilitate a better fit around the tooth and allow for easier manipulation and control of the dam, enhancing the isolation required for various dental treatments.

This design is particularly useful for cases where maintaining proper positioning of the dental dam is crucial, such as during restorative or endodontic procedures. Winged clamps aid in accommodating different tooth shapes and sizes, making them a popular choice in clinical practice for ensuring that the dental dam remains securely in place throughout the procedure.
