Fig. 258. — Tables of incisors (nat. size). 



The chief features in these teeth (Figs. 256, 257 and 258) are : 

 increased length of crown; decrease of width of the neck of the 

 corner incisors of the upper jaw (Fig. 256) ; increased obliquity of 

 the lower incisors; and decrease of the width of the tables of the 

 central and lateral incisors (Fig. 258), which fact brings them 

 nearly into a straight line in each jaw. Hence, when seen from 

 the front (Fig. 257), the upper corner incisors are well in view. 

 The fact that the upper incisors partly cover the lower incisors 

 of the mouth shown in Fig. 256, gives a false appearance of obliquity 

 to the lower incisors in Fig. 257.
