Excerpt from The Dental Summary, Vol. 26 The post of the dowel crown, as described by writers and clinicians, is a straight, round platinum wire about number twelve gauge. Those who are frequently called upon to remove and reset such crowns should recognize that this small post is the weak point and real cause of failure of the majority of crowns so con structed. Where these crowns are set on roots improperly pre pared, with the canals considerably larger in Circumferences than the post, as is often done, the force of mastication soon forces the post loose from the cement that anchors it and repeated re cementing, or a new crown, is the result. In crowning anterior teeth three important steps in prep aration should be observed. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
