Air-driven handpieces are dental tools powered by compressed air. They are commonly used by dentists for various procedures, such as drilling and polishing teeth. These handpieces are lightweight and provide high-speed rotation, making them efficient for tasks that require precision. The design of air-driven handpieces allows for easy maneuverability in the mouth. They typically feature a turbine that spins when air is directed through it, generating the necessary speed for dental work. Many dentists prefer these handpieces for their reliability and ease of use, contributing to effective patient care in the field of dentistry.
