Final answer:
The right-angle handpiece should be held with a modified pen grasp, which is essential for precision and control. A firm grip involving the thumb, index, and middle fingers aids in maintaining accuracy and preventing hand fatigue.
Step-by-step explanation:
The right-angle handpiece is held with a modified pen grasp. This type of grip is utilized in various healthcare practices, including dentistry, to allow for precision and control during procedures. Holding the handpiece in this way involves a specific technique where the thumb, index finger, and middle finger are used to grip the instrument, much like how one would hold a writing instrument, but with slight modifications for improved control and reduced fatigue. It is important to grip firmly to ensure accuracy and to avoid slippage, all while maintaining a comfortable posture to prevent hand strain. The opposition movement of the thumb toward the fingers is vital in this grasp as it makes it possible to firmly hold objects and perform delicate tasks.
