Seating of composite inlays with ultrasonic vibration

The use of vibration enables the clinician to use high-viscosity luting agents when seating composite inlays and allows quick and efficient placement of the inlay. The film of composite luting agent is achieved in a much shorter time and with lower loads by ultrasonic vibration than using manual methods. In order to achieve a thin lute, the vibrations of the ultrasonic scaler must be directed perpendicular to the surface of the inlay.
