Abstract
An ultrasonic dental scaler insert includes a tool coupled to a connecting body which is mechanically coupled to a transducer. When the insert is placed within an ultrasonic dental scaler device handpiece, the transducer produces ultrasonic vibrations which are transmitted to the tool via the connecting body. In order to reduce the noise generated by the operating scaler insert, the connecting body includes an elastomeric material which surrounds a portion of the connecting body. Additionally, a sleeve is provided which surrounds a portion of the connecting body providing a place to grasp the scaler insert during operation. The sleeve includes a bellows section which provides vibrational damping for the insert. Furthermore, the connecting body includes a vibration dampening bushing at an end adjacent the working tool.
