When there is a malposition ofthe cuspid on one side of the maxilla, the cuspid of the oppo-site is usually pushed forward, as seen in the same illustra-tion. Owing to a malposition of the germ, the cuspid may befound outside of the incisors in the median line (Fig. 212), oreven inside of the arch (Fig. 213). Karely it is found onthe median line between the incisors, as shown in this illus-tration. 460 ETIOLOGY OF OSSEOUS D

Like the cuspid, the position of the bicuspid is most fre-quently affected by the forward movement of the posteriorcolumns. An irregularity in a lateral direction is rare, sincethe density of the lower maxilla is unfavorable to this. Whenever a bicuspid is found without or within the arch,it is due to the undue retention of the temporary Fig. 213.
