Abstract
In a method for controlling a torque of a motor of dental and surgical handpieces to not exceed a set-point value when screwing in implant members, a motor current for applying the set-point torque is determined immediately before screwing in an implant member with the handpiece and the motor current is limited to the set point value with a motor control during subsequent screwing in of the implant member. The device for carrying out the method has a torque limiter, connectable to a tool receptacle of a handpiece, and a motor current measuring device for measuring a motor current of the motor of the handpiece.
