What type of grasp is used for the removal of cement?

The modified pen grasp is the correct choice for the removal of cement. This grasp allows for better control and precision, which is essential when working in tight and delicate areas of the mouth, such as when removing cement from dental restorations. The modified pen grasp involves holding an instrument with the thumb and index finger while allowing the middle finger to rest against the instrument for stabilization. This positioning enhances dexterity and provides the dental assistant or hygienist the ability to maneuver effectively while minimizing the risk of injury to the patient or damage to the surrounding tissue.

In contrast, the standard pen grasp may not provide the same level of control needed for intricate tasks, while the palm grasp is generally used for instruments that require a firmer hold, such as certain handpieces, and is less appropriate for fine tasks like cement removal. The thumb grasp typically does not offer the precision required for such detailed work. Therefore, the modified pen grasp is the most effective and preferred technique for this specific procedure.
