THE RELATIONSHIP BETWEEN THE WIDTH OF THE MOUTH, INTERALAR WIDTH, BIZYGOMATIC WIDTH, AND INTERPUPILLARY DISTANCE IN EDENTULOUS PATIENTS

The width of the mouth, interalar width, bizygomatic width, and interpupillary distance were measured in edentulous patients. The widths varied widely, even when the population was separated into groups by sex and/or race. When mean values were studied, black men differed significantly from black women, white women, and white men in interalar and bizygomatic widths; white women differed from the other groups in all widths. No correlation was found between the widths for the population as a whole, nor when the population was further divided into race, sex, or group. When artificial teeth were chosen for eight randomly selected patients using a method recommended for each of the widths, the same mold was dictated by two methods for seven patients, and by three methods for five patients.
