We now have a plate tooth, gold backed,with a tube-pivot, the orifice of which opens on the palatalaspect of our tooth. The root-end of the tube is now slit per-pendicularly in three or four places, for about two-thirds of itslength, a thin sheet of warmed gutta-percha is placed on thebase of the crown around the tube, and the whole is pushedsecurely to place. Xow pack gold or tin into the tube, condensingthe bottom portions so that the slit end mill spread and tightly fill thedared end of the hole in the root, and the operation is complete. A collar crown fastened with a tube-pivot as described can beused to advantage in detachable bridge-work, as the tube iffilled with tin foil will admit of the crown being easily 1 Dental Cosmos, May, 1883. 126 ARTIFICIAL CROUX- AXD BRIDGE-WORK.
