Which clamp is designated for use with four premolars?

The clamp designated for use with four premolars is identified as the W2A clamp. This specific clamp is designed with features that suit the anatomical contours of premolars, providing a secure fit and effective isolation during dental procedures. The W2A clamp has a shape and size that accommodates the narrow and sometimes variable widths of premolar teeth, allowing for better access and visibility for the dentist while preventing any moisture contamination in the treatment area.

The other options listed are designed for different purposes or specific teeth. Options such as the 0, 2, and 2A clamps serve different tooth categories such as molars or anterior teeth, or they may have compliance limitations relating to tooth size or shape, making them less suitable for four premolars. Understanding the specific applications for each clamp helps practitioners select the appropriate tool for optimal dental treatment outcomes.
