Intercommissural width in 4 racial groups as a guide for the selection of maxillary anterior teeth in complete dentures.
OBJECTIVE
To determine whether intercommissural width is a reliable guide for the selection of maxillary denture teeth width.


METHODS
Casts were made of 160 subjects from 4 different racial groups. Locations of intercommissural width landmarks (the corners of the mouth) were made on the subjects and transferred to the casts. The distances between the corners of the mouth and the distal of the canines were measured on the casts and compared.


RESULTS
A weak correlation was found between the distal of the canines and the distance between the corners of the mouth in the 4 racial groups.


CONCLUSIONS
The use of the corners of the mouth for the selection of artificial teeth is generally inaccurate.
