A practical treatise on artificial crown- and bridge-work . Fig. 70 Fig. tail form, as shown m cross-section by Fig. 69, Avhere the crownis seen in place over the posts on the root. It is thus madeobvious that the crown may be easily put on and oft the root inthe process of fitting the crown-neck to the root-neck, and alsothat, for occlusion, the crown may be ground low on any or allsides without destroying the dovetail function of the centralcavity. When the fitting is completed, and the crown cut soshort as to be -gL of an inch distant from the occluding tooth,amalgam is packed into the neck recess, around the posts, andthinly over the cervical margin of the root, the crown put inplace, and, with thumb pressure, firmly seated. Then test theocclusion, and complete the operation by packing amalgam intothe crown opening, which will permit the forcing of the amalgamin all directions, to injure a firm base for the crown, and itssecure dovetail attachment to the posts, as shown by Fig. 69. The bicuspid crown (Figs. 70 and 71) is similarly mounted,as may be see
