An air-driven handpiece is a dental tool powered by compressed air. It is commonly used by dentists for various procedures, such as drilling and polishing teeth. The handpiece operates by converting air pressure into rotational motion, allowing for precise and efficient work on dental surfaces. These handpieces are lightweight and easy to maneuver, making them a preferred choice in dental practices. They typically feature a high-speed option for cutting through hard materials and a low-speed option for more delicate tasks. Regular maintenance is essential to ensure optimal performance and longevity of the handpiece.
