Which of the following is NOT a common grasp for using the HVE?

The common grasps for using the high-volume evacuator (HVE) tend to follow specific hand positions that allow for optimal control and maneuverability during dental procedures. The "thumb to nose" grip enables a firm hold while allowing the clinician to navigate the HVE effectively within the oral cavity. The "pen" grasp mimics writing, offering comfort and precision, whereas the "modified pen" grip provides enhanced stability while ensuring the operator can easily manipulate the tool.

In contrast, the "web grasp" is not a typical grip used for the HVE. This grip, which involves holding the instrument with the web of the hand, doesn’t provide the necessary dexterity and control required during procedures that demand fine motor skills. Therefore, it stands out as less effective and is not commonly employed compared to the other established grips, emphasizing the importance of adaptability and ease of use when handling suction equipment in a dental setting.
