What are the main benefits of an electric handpiece vs. an air-driven system?
• Smooth, quiet operation and consistently high torque throughout the entire speed range are the two most important features that distinguish an electric motor from an air-driven high- or low-speed handpiece. The torque produced by an electric is nothing short of amazing! An air-driven high speed will lose power when put under pressure, but an electric will maintain its speed, because the motor will take up more energy. This is especially beneficial during gross reduction procedures. There is no “chatter” when removing old metal-based restorations or when prepping for crowns and bridges. The consistant torque allows the clinician to easily produce accurate, defined, and smooth margins, leading to better impressions and perfectly fitting indirect restorations from the laboratory. Since the attachments in an electric system are all gear driven, clinicians experience quiet operation and less vibration to their hand and concentric cutting on the patient’s tooth. • Another benefit is that t
