The ROTARY MASTER device is a control unit that drives a dc electric micromotor that can be turned on or off by a foot switch. It is intended for use in general dental applications such as cutting a tooth for crown preparation, cavity preparation, finishing the crown, inlay, or filling, polishing, prophylaxis and endodontic treatment, with use of a straight, right-angle, or contra-angle ISO E-type attachment of equal speed, speed increasing or decreasing sheath. The micromotor speed is adjustable by the control knob on the front face of the control unit from 2,000 to 30,000 rpm.
Special Note: Because the electric motor and its cord are not autoclavable, an adequate covering by plastic sleeving as commonly used in dentistry for infection control should be used during treatment.
