Abstract: A vibrator utilizing a disposable bite probe subject to vibrations of the vibrator is used to seat crowns, bridges and the like. After cement has been applied to the underside of the crown and the prepared tooth surface and the crown initially positioned, the bite probe is received between the crown and opposing teeth in the patient's mouth or dentist's finger in the absence of opposing teeth, the patient or dentist applying pressure on the bite probe. When the vibrator is energized, the vibrations express excess cement working the crown down into a proper and secure position on the patient's tooth. Continued pressure on the bite probe by the patient and/or dentist holds the bite probe in position, the vibrator itself being disconnected from the probe and the probe itself being retained in a stationary position for a sufficient length of time to assure proper seating of the crown as the cement hardens.
