Which clamp is most commonly used for a class V restoration?

The most commonly used clamp for a Class V restoration is the butterfly clamp, specifically models 212 or 214. These clamps are designed to provide excellent visibility and access to the gingival margin during the restoration process, which is crucial for achieving a successful Class V restoration that typically involves the cervical area of the tooth.

Butterfly clamps have distinctive wing-like extensions that facilitate easier adaptation to the tooth's anatomy and allow the dental assistant or dentist to work around the marginal areas without obstruction. This is particularly important in Class V restorations, which are often located on the facial or lingual surfaces, close to the gum line, making access challenging.

Other clamps, such as Young’s clamp and winged clamps, may not provide the same level of accessibility and visibility specifically needed for Class V restorations. While standard clamps might be suitable for various other dental procedures, they may not offer the tailored fit and functionality that the butterfly clamp provides for this particular type of restoration.
