High-speed handpieces are dental tools used by dentists to perform various procedures, such as drilling and cutting teeth. These devices operate at speeds typically ranging from 100,000 to 800,000 revolutions per minute (RPM), allowing for efficient removal of tooth material and quick preparation for fillings or crowns. They are often powered by compressed air and are designed to be lightweight and easy to maneuver. These handpieces are equipped with a variety of bur types, which are small cutting tools that can be changed depending on the procedure. High-speed handpieces are essential in modern dentistry, improving patient comfort and reducing treatment time. Regular maintenance and sterilization are crucial to ensure their effectiveness and safety in the dental office.
