AVhen the teeth have all been lost on one side of the mouth,or are too mucli decayed to serve as a support for an obturator, either with or without artifi-ficial teeth, the plate may beconstructed with two branchesupon the other side, if therebe two healthy and firmly ar-ticulated teeth, to which claspscan be applied. A piece ap-plied in this manner, in con-nection with nine artificialteeth, namely, the four inci-sors, two cuspids, two bicus-pids and one molar, is shownin Fig. 317. The clasps, asmay be perceived by the cut,;ie mtended for a second bicuspid and second molar. Althoughthe molars on the opposite side of the jaw were absent, it wasnot deemed prudent to increase the weight of the piece by at-taching more than nine artificial teeth to the ARTIFICIAL PALATES AND OBTURATORS. 855 Fig. -MS. An artificial palate, complicated with ten artificial teeth,namely, the central and lateral incisors, the cuspids, the firstbicuspid of the left side, tiiefirst and second of the right, aswell as the first molar, is repre-sented in Fig. 318. The clasps,as maybe seen, are for the firstmolar of the left side and thesecond of the right. The open-ing in the palate to be coveredby the plate, in this case, ex-tended from the alveolar borderbackward a little more than aninch, and was about seven-eigliths of an inch in width. The functions of mastication, deglutition and speech, whichwere all very greatly impaired by the opening in the palate andloss of so many of the teeth, were, in a great degree, restoredby the piece here represented.
