Now make the pivots or dowels (of platinum and iridium wire),and roughen them before placing in position. Drill holes corre-sponding with the root canals, place the pivots in position, andfasten them to the floor with prepared hard wax. Now removecarefully, and invest pivots, floor, and band in equal parts of plas-ter and marble-dust, and, after removing the wax with boilingwater, unite them with 22-carat gold. Now cut down the over- Fig. 456. Fig. 457. Fig. 458. Fig. 459. Fig. 460.
