Modifications in the Form of Plates for Partial Dentures Sup-ported in the Mouth by Clasps.—The particular form and dimen-sions of a plate, when clasps are used, will be mainly determinedby the number and position of the teeth to be replaced, and by thelocation of the natural organs to which the clasps are will be sufficient in this place to indicate the leading forms asthey relate to the substitution of the several classes of teeth. In Fig. supplying the loss of a superior central or lateral incisor, it willbe sufficient in many cases to attach the plate to either a bicuspidor molar on the same side. If two or more of the front teeth,however, are to be replaced, it is better to extend the plate oneach side of the palatal arch, and attach to a bicuspid or molar(Fig. 80). In all cases where it is necessary to extend a narrowplate from the extreme front part of the mouth to a single toothsituated posteriorly in the arch, the former should be strength-ened by soldering a narrow rim of plate or half-round wire alongthe border next the teeth, and the clasp should, whenever prac-ticable, pass in front of and embrace the anterior face of the toothto which it is applied. If an anterior bicuspid is to be replaced, the plate may beattached to the adjoining bicuspid, or if both are absent, then to I5C MECHANICAL DENTISTRY. the first molar, or the clasp may embrace both of the latter ifr
