Which handle design option is noted to provide a lighter instrument?

The option that provides a lighter instrument is the hollow handle design. Hollow handles are constructed to be less dense than solid ones, allowing for a significant reduction in weight without compromising strength. This design is especially beneficial for dental hygienists who need to minimize hand fatigue during lengthy procedures. A lighter instrument can improve maneuverability and ease of use, which is crucial in maintaining dexterity and comfort during dental hygiene practices.

While solid handles may provide a sturdy grip, they do not offer the same weight efficiency as hollow handles. Textured handles focus on enhancing grip and control, rather than weight reduction. Weighted handles, as the name suggests, add additional mass to the instrument, which is contrary to the need for a lighter tool. Thus, the hollow handle design is the optimal choice for achieving a lightweight instrument in dental hygiene.
