title: The removal of fractured post fragments in general dental practice using ultrasonic vibration.
abstract: This paper describes an evidence-based clinical procedure that is suitable for the removal of fractured metal post fragments using ultrasonic vibration in general dental practice, particularly when non-resin-based cements have been used. Fragments of posts cemented with resin-based cements are likely to be extremely difficult to remove. The use of non-resin-based cements is recommended for luting posts, as fragment or total post removal is much easier with these materials.
