ABSTRACT

Diagnostic indexes are important to predict dental arch size and to suggest the most appropriate treatment plan for each patient. Pont designed a method to determine the width of an ideal dental arch, based on the mesiodistal measurements of the crowns of the upper incisor; besides he provided formulas to obtain norms. The purpose of this study was to determine if Pont’s index norms match the results obtained after non-extraction orthodontic treatment. A cross-sectional, descriptive and comparative study was performed to 54 study models. The statistical analysis showed that there’s a significant difference between Pont’s index norms and the measurements obtained from the models.
