Dental handpiece air turbines, which are also known as air driven handpiece motors, often showcase a motor that ranges from 5,000 rpm to 20,000 rpm. Pressured air and water are often featured as a coolant. Many air driven handpiece motors also provide a light source. Both straight and contra-angle handpieces can be used on most dental handpiece air turbines. Features such as light and coolant can be very beneficial while using these air driven handpiece motors, however, some vendors offer the motors sans features. Dental handpiece air turbines can fit with a variety of dental handpieces, most feature a type “E” connection. It is important to research whether or not the motor can connect handpieces from various vendors.
