title: Removal of parallel prefabricated posts: a clinical report.
abstract: The serrations on some parallel and vented prefabricated posts are continuous spirals. Occasionally removal is indicated. If attempts to loosen the post by mechanical vibration fail, the embedded portion may be removed by turning. Careful examination of the radiograph and the exposed portion of the post is needed to determine the proper direction of torque.
