Arranging the Teeth for a Full Upper and Lower Denture.—In the process of grinding the teeth to the base, above and below, theoperator should commence by first arranging the superior centralincisors, and then the lower, and so, passing back from tooth totooth, grind and adjust an upper and lower tooth alternately, keep-ing the upper ones in advance of those of the lower jaw. The cen-tral incisors above should be placed parallel with each other, but the. ENTIRE DENTURES ATTACHED TO SWAGED PLATE-BASE. 249 cutting edges of the laterals and the points of the cuspids shouldincline slightly toward the median line of the mouth. In arrang-ing the teeth of the upper jaw, the anterior six may be made todescribe, with more or less exactness, the segment of a circle, buta somewhat abrupt angle may begiven to the arch on each side by FlG- I05- placing the first bicuspid within thecircle in such a way that, whenstanding directly in front of thepatient and looking into the mouth,only a narrow line of the exteriorface of the crowns of these teethwill be seen, while the remainingteeth posterior to them should bearranged nearly on a straight line,diverging as they pass backward. When arranged in the manner described, the peripheral outline ofthe arch will exhibit somewhat the form presented in the diagram(Fig. 105).
