is to ?rst set the two central teeth 64 in correct position,
to thereupon position the two laterals 66 properly, and to
?nally set the two cuspids 68 in proper position, all as
shown in FIG. 4 with respect to a maxillary model 70.
The ?ange 24 is placed in the hamular notches of the model
70 and face 16 of the panel 12 is brought into engagement
with the centrals 64. The technician can thereupon
visually determine whether or not the laterals 66 and the
cuspids 68 form the correct smile line, thereby eliminating
