Abstract Purpose The aim of this study was to determine if there were any cast measurements that could help the clinician in predicting the width of maxillary anterior teeth. Material and methods 30 pairs of edentulous casts with good ridges and no relevant clinical abnormalities were selected. On these casts occlusal rims of standard dimensions were constructed and were then adjusted in the patient’s mouth according to esthetics, speech and other occlusal considerations. Canine lines were scribed on theses rims, and the canine-to-canine measurement served as the control. Six measurements were then made on the casts. The estimation bias for each of the six measurements was then determined. For those measurements for which the bias was significantly different from 0, a bias corrected version was obtained. The measurements along with the bias correction were then calculated for each set of casts and a Karl Pearson correlation coefficient was calculated to check for the maximum correlation with the control (canine-to-canine). Result The bias-corrected measurement from the left hamular notch mark to the right hamular notch mark (left hamular notch mark to the right hamular notch mark + 10 mm) was shown to provide the greatest degree of agreement with the control canine-to-canine measurement for selecting denture teeth for all cast sizes.
