MANIPULATING COHESIVE GOLD 157 when it is filled separately as before with hand pressure, then condensed with the mallet and afterward united to the main body of gold (Figs. 194 and 195). In proximo-occlusal cavities the same procedure is followed until the top of the step is reached. Then fill the con\enience angles separately at the far end of the step, later uniting them, and then building the gold across the step and uniting it with the first portion of the filling (Figs. 196, 197, 198, 199, 200 and 201). 7. Build the rest of the filling toproper restoration of contact and occlu-sion form, leaving an excess of goldover the cavo-surface angle, and thebalance of the surface to allow for fin-ishing (Fig. 202). 8. After Condensation.—Go over the entire filling witha small foot plugger, and thoroughly Fig. 202—The two portionsunited and the filling com-pleted. Ten Rules for Plugging Cohesive Gold 1. Pluggers.—Use pluggers ranging from 1/2 to i milli-meter in size, 1/2 millimeter for starting in convenienceangles, and larger sizes up to i millimeter for building. 2. Stepping.—Step the plugger in definite lines, movingit only a distance of the diameter of its face, after each thrustor blow, to avoid bridging and imperfect condensation 3. Condensing.—Pack the gold in small pieces and thinlayers, condensing each layer thoroughly by the steppingprocess, to assure thorough condensation. 4. Direction.—Pack in the general direction of the longaxis of the tooth, wherever possible, in order to avoid lateral 158 FILLING MATERIALS strain on the pericementum and to place the layers of gold ina plane with the plane of the forces of occlusion, so that thecrushing stress may be resi
